Abstract

The invention relates to the technical field of pesticides, in particular to a suspending agent containing methoxycarbamate and cyazofamid and application of the suspending agent. The bactericidal composition comprises the following raw materials: active components, wherein the active components comprise methoxycarbamate and cyazofamid; the methoxyl carbamate is pyraclostrobin, and the methoxyl carbamate is pyraclostrobin. The suspending agent provided by the invention has the following advantages: (1) the suspending agent has a remarkable treatment effect on grape downy mildew, and provides a powerful guarantee for high-yield and high-quality cultivation of grapes; (2) the suspending agent has the advantages of easily available raw materials, simple process and strong practical operation feasibility, and can be widely applied to the field of prevention and treatment of downy mildew; (3) the suspending agent has excellent stability while having a high downy mildew prevention effect, can be stored for a long time at high temperature, and is low in decomposition rate and free of layering and color changing phenomena; and (4) the suspending agent is high in safety, does not cause phytotoxicity to crops, accords with industrial regulations in toxicological tests, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a suspending agent containing methoxycarbamate and cyazofamid and application thereof. Background technique [0002] Downy mildew is a type of plant disease caused by the fungus downy mildew, which can cause nearly half of the yield loss in severe cases. Downy mildew belongs to the Downy mildew family in the biological classification, which is the largest order in the Oomycetes class with the highest development stage. The mycelium of Downy mildew is well developed and parasitic in the host cell to absorb the nutrients of the host cell with spherical or linear haustoria. According to the difference of infestation patterns, downy mildew is mainly divided into two types. One is local infection, which is caused by the continuous production of sporangia by spot lesions during the production season, and frequent infection occurs. Fast, is the infection mode of most downy mildew; ...
