Advantages
WERNER is one of the most highly effective fungidides used for pre-sowing seed treatment due to its wide spectrum of action.
It quickly controls the occurrence of diseases and helps the plant produce maximum yield.

Mechanism of action

Azoxystrobin is characterized by contact and translaminar action (eradicates, protects, heals). Interrupts the germination of spores and pathogen mycelium by inhibiting mitochondrial respiration.
Tebuconazole and cyproconazole have a pronounced systemic effect, and after treatment they actively move throughout the plant. They inhibit the conversion of lanosterol to ergosterol, a specific sterol that is part of the cell membranes of fungi. Suppression of ergosterol synthesis leads to irreversible damage to the cell membranes of the fungus, resulting in death.
Impact speed
Has rapid initial activity, protecting plants from the moment of germination.
Spectrum of action of the chemical product
Loose smut, hard smut, false smut, stone smut, Fusarium and helminthosporium root rots, snow mold, seed mold, including Alternaria seed infection, powdery mildew (in the early stages of development), net spot; blister and dusty smut of inflorescences, root and stem rot, molding of seeds.
Period of protective action
The period of maximum protective effect under favorable weather conditions lasts about three weeks (until the tillering phase of the crop) when used as a seed protectant.
Recommendations for use
Before use, stir the contents of the canister well. When treating filmy crops and detecting infection with loose smut, it is recommended to use the maximum application rates of the drug.
A convenient preparative form (suspension concentrate), thanks to the optimal content of the adhesive, promotes uniform distribution and preservation of the active substance on the surface of the seeds. After drying, the treated seeds do not “dust”.
The bright red dye included in the preparation allows you to visually control the quality of etching based on the intensity of the coloring.
Seed treatment can be carried out either in advance (acceptably 1-2 weeks in advance) or directly on the day of sowing. Freshly harvested seeds of winter crops are processed no later than 2-5 days before sowing.
When grain seeds are treated in advance, their moisture content may increase slightly, so treated seeds should be stored in a dry room. Treated seeds should not be allowed to enter the food of animals and birds.
Factors influencing efficiency
For dressing, it is recommended to use seeds free of dust and impurities, which guarantees good adhesion and, therefore, better quality of dressing. In addition, dust can absorb the drug, which leads to a significant decrease in the concentration of the drug falling on the seeds.
It is not recommended to use the drug on sprouted seeds that have cracks or other damage (due to the risk of phytotoxicity), as well as on seeds with a moisture content of more than 16%.
Phytotoxicity
When used in strict accordance with the instructions for use, there is no risk of phytotoxicity. There are no restrictions on the placement of subsequent crops in the crop rotation.
Compatibility
Compatible with microfertilizers, biologically active substances and growth stimulants used at the same time. It has a wide spectrum of action, therefore it is not recommended for use in conjunction with other chemical disinfectants.
In each specific case, it is necessary to check drugs for compatibility.
Storage conditions
When storing, avoid direct sunlight and maintain recommended temperature ranges. Upon expiration of the guaranteed storage period, the drug must be checked for compliance with technical specifications. Once compliance is established, it can be used for its intended purpose.
Applied by crops:
Spring and winter wheat, spring and winter barley, oats, millet, rye.
