Thiabendazole: instructions for use and what preparations contain

When growing vegetables and fruits, it is important not only to use he althy seeds, but also to create conditions for storing the crop. Therefore, it is advisable to use pesticides with thiabendazole at the stages of seed processing, as well as to disinfect premises intended for storing crops. The substance effectively destroys fungal infections and is harmless to fruits.

Physical and chemical properties of the active substance

Thiabendazole has the appearance of a white, odorless crystalline substance. The main characteristics of the pesticide:

• does not dissolve in water;
• is heat resistant;
• does not exhibit carcinogenic properties;
• non-volatile substance. However, at a temperature of 310 ° C, it can ignite without losing its fungicidal qualities. Therefore, often for the fumigation of warehouses with potatoes, checkers from preparations containing thiabendazole are used.

It should also be borne in mind that it is possible to increase the solubility of a substance in case of acidification.

Mechanism of action and scope

The substance is mainly used to protect fruits and vegetables from mold. The essence of processing is the creation of a protective film on the surface of the fruit, which ensures the safety of the crop for six months.

In favor of the drug, it can be added that the processing of the harvested potato crop reduces the infection of tubers with Fusarium rot by 3-4 times.Approximately 7 times the defeat of silvery scab is reduced and 14 times - formose rot. If you process potato seed before planting, then the number of diseased tubers decreases by 10 times.

The principle of action of the pesticide is the inhibition of DNA and RNA nucleic acids in weed plants, which contributes to the termination of the nuclear fission phase. But it must be borne in mind that there is a possibility of resistance to thiabendazole in some forms of fungi. This feature significantly reduces the effectiveness of the pesticide in case of long-term use.

Preparations containing thiabendazole

Manufacturers produce several drugs, the active ingredient of which is thiabendazole. When choosing funds, you need to familiarize yourself with their purpose and method of application.

1. "Vial Trio" is a three-component pesticide (contains thiabendazole, prochloraz, cyproconazole). 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.
2. "Maxim Advance" - a three-component protectant (mefenoxam, thiabendazole, fludioxonil), which 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 assimilation of nutrients by them, and enhances photosynthesis.
3. In personal households, it is effective to use bulk smoke bombs "Vist". The agent is used to protect agricultural products from many fungal infections (dry rot, fusarium, gray rot, phomosis, clamp rot).

How these remedies are used

Vist is a small tablet packed in a plastic box (total weight - 400 g). Since the emitted combustion products are not harmful to animals and people, it is recommended to fumigate the harvest of vegetables and fruits laid down for winter storage.

The preparatory stage is to calculate the required number of tablets, based on the volume of the room. Oriented dosage - one checker per 25 cubic meters. meters. Brief instructions for use:

• in the center of the room, an elevation of non-combustible material about 25-30 cm high is constructed. In spacious warehouses, several coasters are placed in the corners;
• checkers are laid out on stands;
• close tightly all window openings, ventilation holes;
• checkers set fire, leave the room and tightly close the door.

A day is enough for high-quality fumigation of a room. Checkers can be used at any time of the year.

Safety when using

Combustion products of checkers containing thiabendazole are harmless to animals and humans. The substance does not irritate the skin, does not show carcinogenic or teratogenic effects. However, it must be remembered that this is a pesticide, therefore, in large doses, it can lead to poisoning. Symptoms: headaches, nausea, vomiting, drowsiness, fatigue, loss of appetite and diarrhea.Therefore, it is recommended to carefully ventilate the premises after fumigating with checkers.

Thiabendazole can be attributed to substances for various purposes, since it exhibits the properties of a preservative and is effective in combating fungal infections. For the purpose of prevention, vehicles used to transport crops, as well as empty warehouses or premises intended for storing vegetables and grain are processed.
