Tebuconazole, disrupting the formation of ergosterol in fungal cells, suppresses pathogens that cause root rot, smut fungi, molds.

Difenoconazole causes the death of fungal cells through the development of dysfunction of cell membrane structures resulting from blocking of styrene biosynthesis. The compound is effective in the treatment and prevention of helminthosporiosis, alternaria, and fungal smut infections, including dwarf smut of grain crops.

"Oplot" has a therapeutic and prophylactic fungicidal effect, protects grain crops and soybeans from a number of infections by pre-dressing the seed material. The combination of active ingredients allows you to control fungal diseases at all stages of plant development with a minimal risk of developing resistance to the composition in the absence of phytotoxicity.

Fungicide consumption rate

The standards for the use of the drug are regulated by the instructions and depend on the type of culture and pathogenic strain.
