Thiram is highly effective against seed and soil-borne fungal pathogens including damping-off (Pythium, Rhizoctonia), smuts (Ustilago spp.), and certain foliar diseases like apple scab. It's widely used as a seed treatment in cereals, cotton, and vegetables, providing critical early-season protection during germination and seedling establishment.
As a dithiocarbamate (FRAC Group M3), Thiram disrupts fungal metabolism by inhibiting multiple enzyme systems. Its multi-site contact action forms a protective barrier on treated surfaces, preventing spore germination and mycelial growth without systemic activity, making resistance development unlikely.
Yes, Thiram serves dual purposes as both fungicide and bird/animal repellent. When applied to seeds or seedlings, its unpleasant taste deters birds and rodents, significantly reducing crop damage while simultaneously protecting against soil-borne pathogens.
For seed treatment, use slurry or dry formulations at 2-3g/kg seed. As foliar spray, apply 1.5-2.5kg/ha with thorough coverage. Soil drenches (0.2% solution) protect seedlings. Treatment timing is critical - apply before pathogen exposure for maximum efficacy.
Use full PPE during handling due to moderate acute toxicity. Avoid inhalation of dust and skin contact. Implement 24-48 hour REI. Prohibited near water sources due to fish toxicity. Adhere to strict pre-harvest intervals (typically 7-14 days for edible crops).
