Fungicide Pennkozeb: instructions for use, composition and release form

Advantages and disadvantages of the drug

The main advantage of the product is the reliable protection of plant crops from sensitive forms of pathogenic organisms. Also among the advantages of the Penncozeb fungicide are:

eliminating the possibility of developing resistance to the components of the drug;
stimulation of photosynthesis processes thanks to manganese and zinc, which are part of the product;
accessibility and ease of use;
water-soluble powder does not wash away moisture from plants or soil;
not phytotoxic to other plant crops;
increasing planting yields;
Possibility of use in combination with other tank mixtures.

A serious disadvantage of the drug is its high toxicity. It belongs to hazard class 2. This means that the drug may be harmful to human health.

Advantages and disadvantages

Like every chemical used to protect crop plants, Penncozeb has its strengths and weaknesses.

The benefits of using a contact fungicide include:

Possibility of using the chemical throughout the entire period of active growing season of cultivated plants.
Good adhesion to leaves, thereby creating an impermeable film.
Possibility of using the drug to treat various plants, including apple orchards.
Good solubility of the powder in water.
The presence of manganese and zinc in the composition, which additionally feed the root system of crops.
Increase in harvest volume after treatment with Penncozeb.
Ability to combine contact fungicide with other chemicals in tank mixtures.
No addiction.
Safe for birds, bees and fish.

Consumption rate

When treating vineyards against mildew, 20-30 grams of product per 10 liters of water are used. The number of treatments per season is 3-4 times. When spraying potatoes and tomatoes against late blight or macrosporiosis, you need 12-16 grams of fungicide per 10 liters of water. This is enough to process 1 hundred square meters of plantings. The period between processing and harvesting should be at least 20 days.

The fungicide Pennkozeb is also used to protect apple and pear trees from scab along with fruit rot. To do this, you need to mix 20 grams of the drug in 10 liters of water.

The number of treatments of fruit crops per season is 3-4 times.

Step-by-step instructions for use

Tomatoes are treated with Penncozeb during the growing season. The product is easy to use: just dilute the contents of the package with water. There are no difficulties in treating with the product either - the plants are sprayed with the prepared solution.

Instructions for processing tomatoes with Penncozeb:

For treatment, prepare a 0.2% solution of the drug.
For 1 sq. m area, 10 liters of ready-made solution is enough.
The procedure is carried out in the morning or evening on a windless day.
The product is sprayed using a fine spray bottle.
During processing, thoroughly wet the leaves on both sides.
If it rains after spraying, repeat the treatment.
The procedures are carried out at intervals of 7–10 days.

Safety precautions

The fungicide belongs to toxicity class 2. This means that it is hazardous to the health of humans and honey insects. To prevent intoxication of the body, you must adhere to safety rules. These include:

Availability of a change of clothes that can be used when working with chemicals. To do this you need to use things made from thick fabric. It is also recommended to have personal protective equipment in the form of a headgear, vacuum goggles, respirators for respiratory protection, and a rubber apron.
Checking the serviceability of the sprayer using water.
The procedure is recommended in the absence of wind and rain, in the morning or evening.
It is not recommended to drink, eat or smoke during the procedure, as this can lead to intoxication of the body.
After the treatment, you need to neutralize the spray tank with a 5% soda solution or laundry soap.

Is there compatibility?

The only thing you cannot use a contact fungicide with is highly alkaline and highly acidic preparations. Penncozeb is perfectly combined with other chemical plant protection products in tank mixtures.

However, to be more sure of compatibility, it is recommended to conduct a test using a small amount of drugs.

Are there any analogues?

If it is not possible to purchase the drug, it is recommended to use the fungicides Bayleton, T-Rex and Bayzafon. These alternative products have a similar composition and effect, which allows them to be used as a replacement for the main pesticide.

The fungicide Penncozeb is one of the most effective drugs that will protect plant crops from scab, fruit rot, late blight and macrosporiosis. The use of such substances is effective if the instructions for use and safety regulations are followed. This will make spraying beneficial for the crop and safe for health.

Instructions for use

When spraying cultivated plants, you must adhere to the instructions for use in order to get rid of fungal microorganisms and not harm vegetables and fruits. Plants are treated in dry weather; the maximum air temperature should not exceed 30 degrees. Also, do not spray in windy weather so that droplets of the solution do not fall on neighboring crops. After the work, people can go to the fields a week later; mechanized work is allowed after three days.

Characteristics of the fungicide Penncozeb

Penncozeb comes in the form of a wettable powder whose active ingredient is mancozeb. The content of this substance in the fungicide is 800 g per 1 kg. Thanks to the action of mancozeb, Penncozeb effectively protects crops from the penetration of harmful pathogens. The period of protective action lasts up to 15 days. At the same time, the speed of action of the fungicide Pennkozeb is high: it begins to act effectively within 24 hours from the moment of spraying. To avoid the development of resistance to Penncozeb, it must be alternated with fungicides belonging to different chemical groups.

Phytotoxicity

Compatibility with other pesticides

The drug is compatible with most fungicides and insecticides, with the exception of highly alkaline and highly acidic substances. It is recommended to check compatibility before use.

Zinc is a key microelement for plants

The role of zinc in plants

In general, Zn is poorly available in soil, especially in areas with pH (>7) and high doses of phosphorus fertilizers and organic fertilizers.
Zinc is a very expensive micronutrient, so it needs to be used at the right time and dose - spraying is the best option.
Elemental Zinc present in the soil is not available to plants.
Only Zn2+ ions are absorbed from the soil.

Storage conditions

The shelf life of the chemical product is 2 years from the date of release, provided the packaging is sealed, so it is better to purchase small volumes of the fungicide for private households.
