Monolith

Synergy of active components in «Monolit»

The fungicide seed treatment «Monolit» by Ukravit is a complex solution for protecting sunflower seeds and winter barley. The technical value of the product lies in the combination of four active substances belonging to different chemical classes: triazoles (tebuconazole, epoxiconazole), oxathiins (carboxin), and neonicotinoids (imidacloprid). This "layering" allows for the simultaneous control of both soil-borne pathogens and hidden infections within the seed.

Why this composition is effective

• Triazoles: Tebuconazole and epoxiconazole block ergosterol biosynthesis in fungal cells, disrupting their membrane integrity. This is a crucial step in suppressing Fusarium and Helminthosporium root rots.
• Oxathiins: Carboxin is a highly specialized component that effectively blocks succinate dehydrogenase in fungal mitochondria, which is critical against the complex of seed molding.
• Imidacloprid: The systemic action of the neonicotinoid ensures protection of seedlings from early soil pests, preventing damage through which fungal spores often penetrate.

The formulation — a suspension concentrate — is specifically chosen to ensure even distribution of active ingredients across the seed surface, creating a durable, «monolithic» protective coating. At a dosage rate of 1.0 to 2.0 L/t, agronomists achieve a balanced concentration sufficient for robust root system formation without phytotoxic effects on seedlings.

Practical application details

The systemic mode of action protects not only the seed but also the primary root system during the initial growth phases. This is vital when facing threats such as Phomopsis, white and grey rot, and Alternaria. It is essential to follow the protocol: the maximum number of treatments is limited to two, and the pre-harvest interval is 30 days. The product is classified as hazard class 3, requiring standard safety precautions when handling agrochemicals.
