Melef Protekt

Technological Profile: Metalaxyl-M as a Foundation of Protection

The systemic efficacy of "Meleph Protect" is built upon a combination of Metalaxyl-M and specific amino acid derivatives. Unlike contact-action products, this fungicide penetrates the seedling, creating a protective barrier within plant tissues from the moment of germination. The use of a seed treatment emulsion allows for a uniform distribution of the active ingredient across the seed coat surface, ensuring a stable concentration of the preparation even if the seed material has an irregular structure.

Pathogen Suppression Mechanism

The primary objective of the product is the control of Pythium root rot and downy mildew during the early vegetative stages of sunflower and corn. Phenylamides, the chemical class to which the active substance belongs, interfere with the synthesis of the pathogen's ribosomal RNA, blocking its growth at the cellular level. This is critical for protecting fragile seedlings in conditions of high soil moisture, where the risk of oomycete development increases significantly. The amino acid derivatives included in the formulation act as binding agents, facilitating the penetration of the fungicide and mitigating stress on the young plant.

Application and Safety Considerations

The product is classified as a Hazard Class 3 agent, requiring standard safety protocols when operating seed treatment machinery. The systemic mode of action provides an extended protection window, covering the most vulnerable development phase of the crop. Precise equipment calibration during the application of the emulsion is essential for effectiveness: the preparation must fully encapsulate the seed, forming a protective layer that does not flake off during transport or sowing.
