Plant diseases
Tomatoes suffer the most from late blight. It happens that in a day or two the entire harvest is lost. The plot is black, as if scorched, the fruits are rotten. This happens very quickly. Sometimes one or two days are enough to lose the harvest.
Potatoes also suffer from late blight. But his tubers remain intact, although they are also covered with rough growths.
Onions are affected by pernosporosis. It rots and cannot be stored.
Grape bushes are affected by a disease called mildew. Its berries crack, darken, and become unfit for consumption.
All these diseases are caused by fungal infections.
Fungal diseases
Pathogenic fungi tend to multiply actively in warm weather. This happens especially quickly at high air humidity. The disease develops very actively, covering large areas. In one day it can destroy the entire crop.
Late blight is especially dangerous for tomatoes. If the onion stops growing after being affected by downy mildew, but can be eaten, then only wilted bushes with black-brown leaves and fruits may remain from the tomato plantation.
Conditions conducive to defeat
Mostly fungal diseases affect plants after heavy rains. The high humidity that follows them promotes the rapid spread of diseases. Although rain itself retards the development of spores, plants begin to disappear soon after heavy rainfall.
Thickened plantings contribute to the rapid spread of diseases. In areas where fresh air easily penetrates between the plants, they are well illuminated by the sun, fungal diseases do not linger for long. A few weak fruits or even bushes may disappear, but the bulk of the harvest will remain.
Compatibility with other agrochemicals
It is not advisable to mix the drug with other chemicals when preparing it. It is impossible to carry out joint treatment with fungicides, since Profit Gold itself is a powerful 2-component product with different directions.Combination is allowed only with stimulants and single regulators. Such preparations should not contain alkaline bases. Among them:
- "Epin"
- "Ribav"
- "Zircon".
Treatment
There are many traditional ways to prevent and treat these diseases. This is a treatment with a solution of potassium permanganate, boric acid, and iodine. These drugs are alternated so as not to cause addiction. But all of them can only slow down the development of the disease and do not help in the event of a mass outbreak of the disease.
Therefore, whether we like it or not, we have to resort to the effects of chemicals.
Nowadays, agronomists have a fairly wide selection of products for treating plants against fungal diseases. Some have a contact effect (affect areas where the product has come into contact), others have a systemic effect.
Plants are sprayed with preparations containing copper (Bordeaux mixture, copper oxychloride). The first time is during the formation of the main number of fruits. The second - in a week and a half. This could be Energen, the organic drug Fitosporin.
Advantages over analogues
The drug has many advantages, which makes it one of the best among fungicides:
- immediate effect on pathogens;
- guaranteed protection for 2 weeks;
- does not wash off during watering and rain;
- gives an effect regardless of the severity of the infection;
- Can be used for all varieties and hybrids of tomatoes;
- no phytotoxicity effect;
- can be constantly used up to 4 times per season;
- pathogenic pathogens do not develop resistance to the drug;
- convenience and economy.
The drug is stored for 2 years. The optimal temperature range is from -30 to +40 degrees.
"Profit Gold"
The fungicide "Profit Gold", or "Profit Gold VDG", receives good reviews. It belongs to the combined drugs of contact-systemic action. Its constituents, cymoxanil and famoxadone, successfully fight pathogens of diseases such as late blight, pernospora, alternaria, and mildew. The first of them penetrates inside the plant, and the second remains on the leaves and protects them. This allows you to use “Profit Gold” against late blight. Reviews indicate the effectiveness of such treatments.
The drug is of French origin. Water-soluble brown granules are the release form of Profit Gold. Customer reviews confirm that they dissolve quickly and completely. As a result, the sprayer used to treat the plants does not become clogged. The granules have a slight odor.
Intended for use in the Profit Gold household.
Application regulations
"Profit Gold" is used in the form of an aqueous solution, which is prepared immediately before use. Plantings are treated by uniformly irrigating the vegetative mass from a spray bottle or garden sprayer until the surface is completely moistened. For work, choose dry weather without sharp gusts of wind. It is advisable to carry out the treatment in the morning or evening.
The first irrigation is performed preventively, without waiting for the symptoms of the disease to appear . If necessary, the treatment is repeated up to 4 times per season with a frequency of 10-15 days.
Important! "Profit Gold" belongs to the reserve type of fungicides. This means that you need to wait a certain time between the last use of the drug and harvesting the fruits. As a rule, the interval should be at least 2 weeks.
The concentration of the working solution depends on the crop being treated. The granules are diluted with clean water in accordance with the table:
Culture | Required volume of water per 1 sachet (1.5 g), l | Treated area, m² | Processing regulations | Waiting period, days |
Potato | 1,25-2,5 | 25 | Spraying tops 3-4 times until the rows close | 15 |
Open ground tomatoes and cucumbers | 2,5 | 25 | The first treatment in the first days after planting the seedlings in the ground, the second and third with a frequency of 2 weeks | 21 |
Grape | 3,5-4 | 40 | Irrigate the vine three times before flowering with a break of 2-3 weeks | 30 |
Floral and decorative | 1,5-3 | 30 | Irrigation of flower beds and rose gardens up to 4 times per season | – |
Onion | 1,2-,3 | 25 | Spraying onion beds three times during periods of intense feather growth | 21 |
Houseplants | Until 3 | – | Irrigation until the leaf is completely moistened: the first treatment is for preventive purposes, subsequent treatments when symptoms of infection appear | – |
Preparation for using the drug
Procedure:
- Prepare an appropriate container. Do not use utensils intended for eating!
- Measure out 1/3 of the recommended volume of water.
- Add the calculated amount of the drug (see table) with continuous stirring until the granules are completely dissolved.
- Add water to the required volume without stopping stirring.
- Fill the sprayer with the working mixture, adjust the nozzle to fine mode and begin processing. The freshly prepared solution should be used within 24 hours, since it cannot be stored.
Instructions for use
Reviews from gardeners say that preparing the solution is easy. Like any dry medicines, the contents of the package are dissolved in a special container in a small amount of water, stirring until completely dissolved. Then add the required amount of water. It depends on the type of plant. For tomatoes and potatoes this is from 5 to 10 liters, for grapes - 15 liters. This largely depends on the quality of the sprayer. This amount of solution should be enough for 100 square meters of potatoes or tomatoes and 150 square meters for grapes.
Having prepared the solution, immediately begin processing the plants. It is advisable that the weather at this time be calm, but not very hot and dry. Leaves and stems are evenly moistened with the solution. If not all of the product is used, then it is not left on the second day, as it loses its healing properties. At the end of the expiration date, the container and unused “Profit Gold” preparation are burned.
Reviews from flower growers say that the product is used for spraying indoor flowers and soaking them for prevention during replanting. The drug protects flowers for one to two weeks.
What diseases does the drug fight?
It can cope with the simplest microbes that cause fungal diseases, even those that are resistant to other drugs. "Profit Gold" can be used on any non-flowering plants. They are processed by:
- beets, potatoes from anthracnose and alternaria;
- tomatoes from stem rot and late blight;
- mildew grapes;
- onions for peronosporosis;
- various crops against powdery mildew;
- strawberries from brown spot;
- flowers from septoria;
- indoor flowers.
Number of treatments with Profit Gold
Reviews indicate that treatment should begin before the first signs of the disease appear - in mid-summer. Then repeat after one or two weeks. The area between the bushes is lined with mulch from mown grass.
In total, tomatoes and potatoes can be processed 4 times, and grapes - three. The last treatment is carried out on tomatoes and potatoes two weeks before harvesting; for grapes this period increases to a month.
Application area
"Profit Gold" is used to prevent and treat an already established fungal infection on any non-flowering crop plantings. The drug is effective against:
- late blight (both stem and leaf forms) and Alternaria of nightshades;
- mildew or downy mildew of grapevine;
- phomosis, downy mildew, phomopsis, gray and white rot of sunflower;
ALL areas of application of Profit Gold (click to expand)
- septoria of wheat and barley;
- brown spot of strawberries and garden strawberries;
- downy mildew of all bulbous plants;
- septoria of flower and ornamental crops;
- fungal infections of various etiologies in indoor potted plants.
The appearance of dark spots on potato tops is the first sign of damage by the late blight pathogen.
The development of late blight is facilitated by high humidity - rain, dew, fog, contrasting temperature changes during the day. To rid tomatoes and potatoes of harmful fungus, it is necessary to take preventive measures. Indeed, when suitable weather conditions occur, late blight spreads rapidly. The new drug “Profit Gold” is ideal for preventive purposes. At high humidity, it destroys infectious agents with even greater force. The advantage is that it is possible to carry out up to 3-4 sprayings per season.
Editor-in-Chief of the newspaper “6 Sotok”, TV presenter, journalist Andrey Tumanov.
To identify the symptoms of late blight on tomatoes and promptly begin to combat the infection, it is necessary to carefully inspect the plantings throughout the growing season.

The main disadvantage of a fungicide is that it is only most effective in wet, cool weather. Profit Gold also treats a limited number of fungal diseases and is used for a limited number of crops.
Gardeners' opinions
User reviews indicate that the drug stops the spread of the disease. They say it's Ridomil, which has a different name. They contain the same active ingredients.
"Profit Gold", customer reviews confirm this, is the best drug for combating late blight. It helps to cure plants in cases where other means fail.
It is not surprising that consumers leave only positive reviews about Profit Gold. For grapes and tomatoes, treatment with the drug is the only way to get a harvest.
Answers to pressing questions
Question No. 1. Does Profit Gold help in the fight against the main pathogens of rose diseases?
“Profit Gold” is guaranteed to cope with fungal infections of roses such as black spot, septoria, rust, and downy mildew. However, it should be kept in mind that this fungicide is not effective against powdery mildew spores. In order to prevent infection and treat various mycoses, rose gardens can be treated several times in one season. The recommended concentration of the solution is 1 g of the drug per liter of water.
Fungal infections of roses, including black spot, respond well to treatment with the Profit Gold fungicide.
Question No. 2. On the forums there are advice from flower growers to water potting soil before planting indoor plants with the Profit Gold fungicide. How effective is this form of application? (click to expand)
Any chemical must be used in accordance with the attached instructions . gives clear recommendations for processing vegetable and horticultural crops exclusively by leaf and stem spraying. This fully applies to indoor plants. It is unacceptable to violate the established treatment regulations: sprinkle the affected areas with dry matter, soak rhizomes and tubers, spill the solution on the soil, etc.
Storage
The drug "Profit Gold" belongs to the third class of danger. It is considered moderately dangerous. Like all chemicals, it should be stored away from children and pets. Drugs should not come into contact with food. The fungicide is suitable for use for two years from the date of manufacture.
What effect does Profit Gold have on insects and fish? Reviews indicate that it is almost not dangerous for bees. The drug is not very dangerous for fish. It can be used in sanitary areas of reservoirs.
Composition, mechanism of action
The drug Profit Gold is based on two active components: famoxadone
and
cymoxanil
. The content of each is ¼ of the total volume. Created exclusively from foreign raw materials. Both substances showed persistence in low acidity environments. And in a neutral or acidic environment, decomposition occurs. At temperatures above +25 degrees it has no effect on pathogens.
Cymoxanil begins its action first. It specifically blocks RNA synthesis in pathogenic microorganisms, ultimately disrupting its entire biological synthesis.
The substance has a limited spectrum of action and acts rapidly within 1 hour after treatment.
Penetrates the green parts, passing through the cuticle. However, further distribution through plant tissues does not occur. The duration of the protection period is from 4 to 6 days. This is generally enough to prevent the fungi from starting to disperse spores.
Anti-phytophthora remedy - PROFIT GOLD
After cymoxanil, famoxadone comes into effect. Unlike the first substance, it penetrates tissue and stops the transfer of negatively charged particles (electrons) in mitochondria.
As a result, pathogens are incapable of mitochondrial respiration. The duration of protection is longer - up to 14 days. As a result, there is no complete destruction of bacteria; only “residues” of mycelium remain, which are completely harmless. Famoxadone is an effective pathogen control agent.
Attention!
Considering the properties of the drug Profit Gold, it is necessary to process the plants exactly on time.
Security measures
They are exactly the same as when working with other chemicals. Do not eat, drink or smoke during treatment. The use of protective clothing and face protection will help avoid contact with the skin and inside the body. If your hands or other parts of the body are splashed with the drug, immediately wash it off with soap and warm water. If the solution does get inside, then you need to quickly give the victim warm water and give him more activated carbon. Then you should induce vomiting and send him to a doctor.
Precautionary measures
To the indicated properties of the Profit Gold fungicide in this section, it should be added that bees, as you know, do not fly to potatoes and tomatoes, and in cool, wet years they do not visit grapes and bulbs - there is no nectar, the pollen is heavy, wet and is not suitable for bribes.
Based on all this, the following security zones for working with the drug are established:
- Apiary – 1.5 km (limited flight of bees for 24 hours).
- Reservoirs, open sources of water supply - according to their water protection zone.
- Children's, medical and recreational institutions, sports grounds, public recreation areas - 150 m (use of areas and institutions for healthy adults - after 3 days without restrictions).
- Open food storages, silos, salting vats, etc. open food and feed processing equipment - 50 m.
- Residential buildings, premises and areas for keeping pets – 15 m.
- Other outbuildings, neighboring plantings - 5 m.
PPE for working with Profit Gold can be simplified: work clothes and shoes, hats, latex gloves, safety glasses. Inhalation of cymoxanil can cause acute poisoning, so you need to put on a filtering respirator with gas cartridges of initial protection level (against aerosols, see figure); it will also cost less than several anti-dust petals for the same total resource.
At the end of the work, the clothes are washed with any detergent (the pH of synthetic washing powders is sufficient to neutralize the DV). Glasses, shoes and gloves are neutralized by washing in a solution of laundry soap and then in clean water; the respirator is treated according to the instructions for it.
If the drug gets on the skin, wash it off with water and wash the affected area with soap; if you get it through wet clothes, wash it in the shower. In case of contact with eyes, rinse them open under running water. If ingested, you need to drink 3-4 glasses of water, induce vomiting and then take a sorbent (3-4 tablets of activated carbon).
Acute poisoning of the DV drug is mildly symptomatic; manifests itself preem. in digestive and respiratory disorders (in case of inhalation). After taking a sufficiently large dose, cardiac disorders are possible; no effects on the nervous system and motor activity were noted. Therefore, if any discomfort occurs while working with the drug and 2-4 days after it, you should consult a doctor. If you feel sick while working, you should, of course, stop immediately.
Profit Gold fungicide is stored under the usual conditions for agrochemicals: in a separate non-residential premises, inaccessible to children and animals, and not intended for storing food products, medicines, clothing (including work clothes) and household items. The temperature in storage should not exceed that indicated on the packaging of the product. Neutralize spilled granules by collecting them in a scoop and pouring them into a waste incinerator. Neutralization of mother liquor and working fluid spilled on the floor - with a soap solution, followed by rinsing with water; spilled on the soil does not require special neutralization measures.
In what cases is it used?
"Profit Gold" is used for the prevention and treatment of fungal infections in any crop plantings.
The action of the product effectively helps with:
- any form of late blight, alternaria;
- mildew, powdery mildew in vineyards;
- Phomosis, Phomopsis, sunflower rot;
- septoria of cereals and flower and ornamental crops;
- spotting of strawberries, wild strawberries;
- peronosporosis of bulbous plants;
- fungal infections of potted flowers.
Trigger mechanism
The two substances that make up the pesticide act harmoniously. Due to this, a combined mechanism of action is triggered. Cymoxanil penetrates plant tissue and destroys lesions from the inside. Famoxadone acts contact-wise, forming a thin film on the leaves and stems. The substance blocks the spread of infection on the surface.

Traditional methods
Plants with weak immunity are susceptible to any disease.
Therefore, in such cases, it is important to have available means with you that at an early stage help prevent the development of late blight
Hydrogen peroxide
The colorless liquid disinfects any damage to tomatoes and eliminates dangerous microbes that live in the soil. Also, due to the oxidative effect, peroxide improves the quality of water for spraying and irrigation.
As a preventative measure, moisten the soil with a peroxide solution at the rate of 3 liters of water per 60 ml of the product. If the disease has already appeared, then treat the stems and leaves with a peroxide solution at the rate of 1 liter of water per 2 tbsp. l. peroxide.
Copper sulfate
One of the advantages of copper sulfate is that it is not absorbed into the soil and tomatoes. The product is available and does not cause addiction in plants. The effect of the treatment lasts for two weeks.
To make the liquid you will need 50 g of granules and 5 liters of water. Treat tomato beds early in the morning or in the evening. If the weather forecast promises rain, it is better to postpone the procedure to another day.
Iodine
Another economical and effective method of preventing and controlling late blight. For 10 liters of water you will need 20 drops of iodine. In addition to treatment, the solution accelerates the development of bushes. It is recommended to treat the bushes with liquid every two weeks.
Experienced farmers also add 1 liter of skim milk to the solution. It forms a protective barrier on the leaves. The medicine can be used even during the ripening period of tomatoes.
Kefir
To make the medicine you will need 1 liter of fermented kefir and 10 liters of water. In humid summer conditions, the bushes are sprayed every week. Also, instead of kefir, whey or milk is used. The product effectively fights fungus on both leaves and tomatoes.
Garlic and potassium permanganate
To prepare the product you will need 100 g of chopped garlic, 1 g of potassium permanganate and 10 liters of water. Spray the beds every 10 days. For 1 bush, 0.5 liters of solution is consumed.
Manganese is one of the most powerful drugs for disinfecting seeds, soil and bushes.
Wood tinder
Since ancient times, the mushroom has been famous for its beneficial properties. Take 100 g of dry crushed mushroom per 10 liters of boiling water. After the liquid has cooled, strain it. Use the product every 10 days.
Chemical fungicides
Among drugs of chemical origin, pesticide-based products are considered especially effective. Many of them have a long shelf life, which means that they need to be used in small quantities.
Bordeaux mixture
The most popular drug for combating late blight on tomatoes and potatoes is the old, proven product based on vitriol and slaked lime. Bordeaux mixture is the most effective drug against fungus. The product is not very toxic. It consists of two substances, each of which has powerful antifungal properties.
A mixture of copper sulfate and slaked lime was invented for plant protection back in the 18th century. Since then, despite the huge number of new drugs against fungal infections, it has been in demand among experienced plant growers.
The drug called "Bordeaux mixture" is produced by many Russian companies, and consists of two separate packages that are mixed according to the instructions. To treat nightshade crops, a solution concentration of 1% is required.
Tomatoes and potatoes are sprayed with the liquid before flowering begins. In greenhouses, floors and all surfaces on which dangerous fungus can live are additionally treated.
Extreme caution must be exercised when working with the drug. The caustic mixture is dangerous to the eyes and mucous membranes
When the period for processing cultivated plants is correctly chosen, harmful substances do not accumulate in the fruits and are therefore not dangerous to human health.
Copper sulfate and copper salts are often used in other preparations in combination with pesticides.
Ordan
Experts recommend the drug Ordan to protect tomatoes and potatoes. This systemic contact fungicide consists of two components that perfectly complement each other. Thanks to this composition, the drug does not cause addiction to the pathogen and can be used several times.
Copper oxychloride in its composition has a bactericidal and fungicidal effect. And cymoxanil, penetrating into plant tissue, destroys spores and regenerates affected cells.
Ordan is slightly toxic to humans and pollinating insects. But in places adjacent to water bodies, it is prohibited to use it.
2 treatments are carried out per season.
HOM
The drug differs little from Bordeaux mixture in properties and composition. But it is much more convenient to use. There is no need to calculate proportions when mixing components and follow the rules for preparing the fungicide. The drug is diluted with water according to the instructions.
The protective effect lasts up to 3 weeks. No more than 5-6 treatments can be carried out per season. The fruits can be eaten no earlier than a month after spraying. For root crops, a twenty-day waiting period is sufficient.
Profit Gold
A two-component preparation containing substances with different effects on the fungus.
Cymoxanil provides systemic action. Penetrating inside, it negatively affects the pathogen and improves the quality of plant cells. External protection lies with famoxadone. This substance kills fungal spores on the leaves and stems of tomatoes and potatoes.
The drug is not phytotoxic, but can be dangerous for humans if the rules of use are not followed. The waiting period from the last treatment is at least 2 weeks.
