TMTD, KS

Mechanism of Action and Technical Efficiency

«TMTD, SC» (TMTD, KS) is a contact fungicide based on thiram, a classic dithiocarbamate. The product functions by creating a protective chemical barrier around the seed, effectively inhibiting the germination of pathogen spores present on the seed surface and in the adjacent soil zone. Manufactured by ZAO Firma August, this formulation is designed for high-performance seed treatment.

Biochemical Basis of Thiram

Unlike systemic fungicides that translocate within plant tissues, thiram works primarily on the surface, blocking copper-containing or sulfhydryl enzymes in the fungal cell. This is vital for early-stage crop development: the substance halts pathogen metabolism before infection can take hold. The high concentration of the suspension ensures uniform coating on seeds of various textures, preventing seed rot, alternariosis, phomosis, and peronosporosis.

Agrotechnical Recommendations

For optimal results when treating sugar beet, winter rapeseed, soy, or corn, adherence to usage protocols is essential:

• Application rate: 1.7–2.3 L/ton, providing a robust protective layer without phytotoxicity.
• Number of applications: 1 (seed treatment prior to sowing).
• Target pests: Alternariosis, Gray mold, Peronosporosis, Phomosis, and seed decay.

The suspension concentrate formulation provides excellent adhesion to the seed coat, minimizing dust-off and ensuring uniform distribution of the active ingredient. Classified as a Class 3 hazard, the product is manageable under standard safety protocols. The technical excellence of this product from ZAO Firma August lies in its ability to sterilize the immediate soil micro-environment surrounding the seed, fostering healthy, uniform emergence even in conditions of high infection pressure.
