Yamb

Technological Synergism in Seed Protection

The fungicide "Yamb" represents a balanced formula for pre-sowing treatment of sunflowers, where effectiveness is achieved through a combination of two chemical classes: phenylamides and phenylpyrroles. This architecture allows the preparation to address seedling protection on two levels: systemic and contact.

Active Ingredients and Protection Mechanics

• Metalaxyl-M (phenylamides): A component with strong systemic action. It is rapidly absorbed by the seed and translocated into the seedling, creating a protective shield against pathogens transmitted via both soil and the seed coat itself. Its primary goal is the control of oomycetes that cause downy mildew (peronosporosis).
• Fludioxonil (phenylpyrroles): Provides contact protection. This substance barely moves within the plant, remaining in the application zone, which creates a long-lasting barrier against fungi dwelling in the root zone.
• Amino acid derivatives: Function as adjuvants and anti-stress agents, facilitating the penetration of active ingredients and mitigating initial chemical stress for the young plant.

The practical value of this combination lies in the control of the full spectrum of sunflower diseases: from root rots and phoma to phomopsis and grey mold. The emulsion formulation for seed treatment ensures optimal coverage of the seed, preventing skips during mechanical processing in treatment machines.

Operational Features

The preparation belongs to the 2nd hazard class, which requires strict adherence to safety protocols when working with treatment equipment. The systemic nature of Metalaxyl-M requires high-quality moisture during seed treatment to ensure the active ingredient can effectively migrate deep into the embryo. Using "Yamb" is a preventive measure: investments in the early stages of vegetation allow for uniform emergence, even under the conditions of a heavy infectious background typical of intensive sunflower cultivation zones.
