When growing vegetables and fruits, it is important not only to use healthy seed, but also to create conditions for storing the crop. Therefore, it is advisable to use pesticides with thiabendazole at the stages of processing seed material, as well as to disinfect premises intended for storing crops. The substance effectively destroys fungal infections and is harmless to fruits.
Physico-chemical properties of the active substance
Thiabendazole appears as a white, odorless, crystalline substance. Main characteristics of the pesticide:
- does not dissolve in water;
- is characterized by heat resistance;
- does not exhibit carcinogenic properties;
- non-volatile substance. However, at a temperature of 310 °C it can ignite without losing its fungicidal properties. Therefore, bombs of preparations containing thiabendazole are often used to fumigate warehouses with potatoes.
You also need to keep in mind that the solubility of a substance can be increased in the case of acidification.
Mechanism of action and scope of application
The substance is used primarily to protect vegetables and fruits from mold. The essence of the treatment is the creation of a protective film on the surface of the fruit, ensuring the safety of the crop for six months.
In favor of the drug, we can add that processing the harvested potato crop reduces the infection of tubers with Fusarium rot by 3-4 times. The incidence of silver scab is reduced by approximately 7 times and the incidence of formosa rot is reduced by 14 times. If you treat potato seed before planting, the number of diseased tubers is reduced by 10 times.
Medicines containing thiabendazole
Manufacturers produce several drugs whose active ingredient is thiabendazole. When choosing products, you need to familiarize yourself with their purpose and method of use.
- "Vial Trio" is a three-component pesticide (contains thiabendazole, prochloraz, cyproconazole).The seed material of grain crops is treated with a water-suspension concentrate. The manufacturer guarantees the effectiveness of the drug in the fight against soil and seed infections.
- “Maxim Advance” is a three-component disinfectant (mefenoxam, thiabendazole, fludioxonil) that provides seeds and seedlings with enhanced protection against fungal infections. At the same time, the drug stimulates the germination of grains, improves the process of their absorption of nutrients, and helps to enhance photosynthesis.
- In private households, it is effective to use bulk smoke bombs “Vist”. The product is used to protect agricultural products from many fungal infections (dry rot, fusarium, gray rot, fomoz, black rot).
How are such means used?
The drug "Vist" is a small tablet packaged in a plastic box (total weight - 400 g). Since the combustion products released are not harmful to animals and people, it is recommended to fumigate the harvest of vegetables and fruits stored for winter storage.
The preparatory stage consists of calculating the required number of tablets based on the volume of the room. The recommended dosage is one shot per 25 cubic meters. meters. Brief instructions for use:
- in the center of the room, a raised platform is constructed from non-combustible material approximately 25-30 cm high. In spacious warehouses, several stands are placed in the corners;
- checkers are laid out on stands;
- close all window openings and ventilation openings tightly;
- The checkers are set on fire, they leave the room and close the door tightly.
For high-quality fumigation of a room, a day is enough. You can use checkers at any time of the year.
Safety precautions for use
The combustion products of bombs containing thiabendazole are harmless to animals and humans. The substance does not irritate the skin and does not exhibit carcinogenic or teratogenic effects. However, you need to remember that this is a toxic chemical, so in large doses it can lead to poisoning. Symptoms: headaches, nausea, vomiting, drowsiness, fatigue, loss of appetite and diarrhea. Therefore, it is recommended to thoroughly ventilate the premises after fumigation with checkers.
Thiabendazole can be classified as a substance for various purposes, since it exhibits preservative properties and is effective in the fight against fungal infections. For preventive purposes, vehicles used for transporting crops are treated, as well as empty warehouses or premises intended for storing vegetables and grain.
