Every agronomist who is engaged in the cultivation of cereals and sugar beets knows that fungal diseases significantly reduce the volume and quality of the crop. Therefore, they use special pesticides to protect plants from pathogenic microorganisms.
One of the most little-known, but effective fungicides is Ferazim, which is used both for preventive treatment and during the period of infection. Let's get acquainted with its description, advantages, features of solution preparation and instructions for use.
Features of the drug
Ferazim - highly effective a systemic fungicide that has protective and healing properties. The drug can replace several other means of similar action, which makes it beneficial and economical.
Purpose and form of release
Fungicide is used for the processing of sugar beets, rye, barley and wheat, as well as for the disinfection of grains. Ferazim drug suppresses the development of many diseases:
- powdery mildew;
- snow mold;
- cercospora (dark brown spot);
- pyrenophorosis (yellow spot);
- fusarium spike;
- rhynchosporia (fringed spot)
- septoria blight of ears and foliage;
- hard and stem smut;
- various rot (root, fusarium, root).
Fungicide released in the form of a concentrated white suspension... On the market, it can only be purchased in a plastic canister with a volume of 10 liters.
Mechanism of action
The active substance of the Ferazim preparation is carbendazim, the concentration of which is 50% or 500 g of the substance per 1 liter of suspension. After 3-6 hours after treatment, the fungicide penetrates the leaves and roots. and is carried throughout the plant tissue. Thanks to its systemic action, the fungicide protects even those parts of the plant that were not sprayed with it.
The active ingredient of the drug Ferazim slows down the process of cell division of pathogenic microorganisms, prevents the growth of fungus and blocks sporulation. A protective film forms on the surface of the plant, which provides protection against re-infection of the culture for a long period.
Dignity
Fungicide Ferazim combines a number of positive aspects:
- can be used both for spraying a plant and for disinfecting seeds;
- long-term protective effect;
- fast action, after 3 hours, the active ingredient of the fungicide already penetrates into the plant tissue;
- the drug spreads throughout the plant and destroys pathogenic microorganisms in all its parts;
- resistant to watering and precipitation;
- does not accumulate in treated plants;
- is effective even after infection;
- prevents lodging of grain crops and promotes their growth;
- does not lose its properties at low temperatures;
- does not cause resistance parasitic fungi to the effects of the active ingredient.
Fungicide Ferazim is a promising drug with many advantages, which is gaining popularity among agronomists.
disadvantages
Plant breeders have identified several disadvantages of Ferazim. It has a high flow rate and is designed to handle large areas.The concentrate is bottled only in 10-liter canisters, which is inconvenient for private and small farms.
Despite the fact that the drug is effective against many fungal diseases, it is not suitable for all crops. The product can only be used on wheat, barley, rye and sugar beets.
Features of the preparation of the solution
Spraying plants with the fungicide Ferazim is carried out when the first symptoms of infection occur every 2-3 weeks... Depending on the type of cultivated crop carry out from 1 to 3 pulverizations for the entire growing season. Disinfection of grains is carried out a couple of days or a year before sowing. The dosage of the concentrate is selected separately for each culture, depending on the processing method.
The diluted Ferazim concentrate cannot be stored for a long time, therefore it is recommended to prepare the working solution on the day of spraying... First comes mix the mother liquor. To do this, add the required amount of fungicide to a bucket of water and stir thoroughly. The spray tank is filled with the remaining clean water, the agitator is turned on, and the mother liquor is gradually poured in. In order for the suspension to dissolve well, the working fluid must be constantly stirred, even when spraying.
Wheat, barley and rye
Ferazim effectively protects crops from root and root rot, powdery mildew, helminthosporiosis, snow mold, various smut and prevents lodging of plants. Diseases can affect both the root system and the aerial part of the culture, including spikelets. They wreak havoc on agricultural production, reducing yields and depleting plants.
Spraying with a fungicide should be carried out when the likelihood of infection arises or when the first signs of infection appear. Plants are usually treated in the spring, but spraying can be done in the fall to protect winter crops. According to the instructions for use, the working solution is prepared from the calculation 10-20 ml of Ferazim concentrate per 10 liters of water. A hectare of planting will need 300 liters of solution (300-600 ml of suspension). It is necessary carry out 1-2 treatments with an interval of 8-14 days depending on the degree of infection.
To etch the grains, the solution is kneaded at the rate of 1-1.5 liters of concentrate per 10 liters of pure water. 10 liters of working fluid are consumed per ton of seeds.
Sugar beet
Sugar beet can become infected powdery mildew and cercospora... The signs and consequences of these diseases are similar: the aerial part of the plant is affected, and spots and plaque appear on the leaves. The tops begin to die off, and a large amount of nutrients are spent on the formation of new foliage. As a result, the weight and sugar content of root crops decreases (with severe damage up to 40-45%).
To prevent powdery mildew and cercosporosis on beets, a solution of the fungicide Ferazim is used. To prepare it in 10 liters of water, you need to dilute 20-27 ml of the concentrate. Per hectare of the site, 300 liters of working fluid (or 600 - 800 ml of suspension) will be required. For greater efficiency you need to carry out 3 treatments with an interval of 8-15 days.
Indoor flowers
The fungicide Ferazim is also used to combat with fungal diseases of indoor and decorative flowers. A solution with a lower concentration is prepared for them: in 1 liter of water is diluted with 0.3-0.5 ml of suspension (you can measure the substance with a disposable syringe). The protective action of the fungicide lasts from 10 to 12 days... To treat flowers, one spraying with Ferazim solution is enough. If necessary, repeat the treatment, but in just a season there should be no more than two procedures.
Compatibility with other drugs
Ferazim can be used in a tank mix with many pesticides that are used at the same time. Fungicide not compatible with drugs that have an alkaline reaction.
In any case, before mixing the mixture, each product must be checked for compatibility with Ferazim. To do this, mix a small amount of drugs and observe the reaction. If a precipitate has formed, agrochemicals cannot be used simultaneously.
Analogs
If the fungicide Ferazim is not on sale, it can be replaced with analogues:
- highly effective drug Fundazol;
- systemic fungicide Derosal, which has a broad spectrum of action;
- contact and systemic fungicide Vitaros;
- Topsin-Mwhich is able to control several diseases at the same time;
- microbiological preparation of a new generation - Fitosporin.
All of these remedies have an active ingredient called Carbendazim. The drugs have similar properties and a broad spectrum of action.
Safety regulations
Ferazim is toxic to humans, it is referred to as to the second class of danger... Therefore, work with the drug should be done with extreme caution. To work with fungicide allergy sufferers, pregnant and lactating women are not allowed. It is not advisable to carry out treatments within a radius of 50 meters from reservoirs and sources of drinking water. Protected zone of apiaries - 3000 meters.
When working with the agrochemical Ferazim, the following safety measures must be observed:
- Availability is required rubber gloves and a respirator mask with gas cartridges. The substance can easily enter the human body through the respiratory tract.
- Work to carry out on open air or in a well ventilated area.
- If the fungicide gets on the skin, wipe the affected area with a cotton pad dipped in a soda solution. Then wash your skin under running water.
- If the drug accidentally gets into the digestive tract, you should drink a couple of glasses of clean water. Induce vomiting to cleanse the stomach. Take activated charcoal according to the instructions and contact a toxicologist.
- After work change clothes, wash your face and hands with soapy water.
The fungicide is stored at temperatures from 0 to +30 degrees.
Conclusion
A large number of different fungicides can scare a novice agronomist. But there is nothing wrong with them. The harm from a progressive disease will be much greater than from the use of an agrochemical. Subject to the instructions, terms and rates of application of the fungicide Ferazim, at the end of the season you can collect a rich and high-quality crop.
