Metalaxyl belongs to FRAC Group 4 and primarily acts by interfering with RNA polymerase I-related processes in susceptible oomycetes. Mancozeb belongs to FRAC Group M03 and is a multi-site contact fungicide that interferes with various biochemical processes in pathogens.
The distinct modes of action of these two active ingredients provide a complementary product positioning for the management of certain oomycete diseases. Relevant target diseases may include certain downy mildews, late blights, and other registered, susceptible diseases.
WP stands for wettable powder; when purchasing, key considerations should include wettability, suspension properties, particle size, active ingredient distribution, and storage stability.
For importers, the evaluation of formulated products involves not only the two active ingredients but also the actual formulation ratio, formulation quality, and registration requirements of the target market. The concentrations and scope of use for different products cannot be applied interchangeably.
Supply Information
MaFa Agro provides supply consultations for Metalaxyl + Mancozeb products and can coordinate formulation specifications, package sizes, brand labels, and quality documentation according to customer needs.
Prior to official release, the original label or COA must be verified to confirm the accurate content and units of measurement for the active ingredients. The currently provided “80 g/L + 640 g/L WP” raises questions regarding the units; therefore, it is not recommended to include this concentration in the official product title at this time.
