Thiram
Description
Thiram is an organic compound belonging to the dithiocarbamate chemical class. In agronomic practice, this substance is widely used as a contact fungicide with protective properties. It lacks systemic properties, so its main objective is to prevent plant infection at early developmental stages or to create a protective barrier on the surface of seeds and fruits.
The mode of action of Thiram is based on the inhibition of enzymatic systems of fungal pathogens that contain copper or sulfhydryl groups. The substance disrupts cellular respiration processes in fungi and blocks the synthesis of essential amino acids. Due to the lack of specific targeting of a single metabolic pathway, the development of resistance in disease pathogens to this fungicide occurs very slowly.
This product is most frequently applied for pre-sowing treatment of seeds of cereals, legumes, vegetable crops, and sugar beets. It effectively suppresses a wide range of pathogens causing root rots, seed mold, cercospora leaf spot, and anthracnose. Thiram can also be used in orchards to protect fruit and berry crops against scab and various leaf spots during the growing season.
When using Thiram, it is critical to ensure uniform coverage of the entire seed surface. Modern seed treatment machines are used for this purpose to allow precise dosage of the solution. In the case of treating vegetation, spraying must be conducted in dry weather so that the fungicide can adhere to plant tissues before any precipitation occurs.
- High efficacy against a complex of fungal diseases.
- Long duration of protective action on seeds.
- Compatibility with other pesticides in tank mixes.
- Moderate toxicity to beneficial entomofauna when used according to regulations.
Handling Thiram requires strict adherence to personal safety measures. The substance is classified as moderately hazardous, so operators must wear respirators, gloves, and protective clothing. It is essential to prevent the product from entering water bodies and to avoid grazing livestock on treated areas during the established re-entry interval.
