Abstract

The invention belongs to the technical field of pesticides, and relates to a compound bactericide of azoxystrobin and polyoxin. The active components of the bactericide comprise azoxystrobin and polyoxin, and the weight ratio of the azoxystrobin to the polyoxin in the components is (20:1)-(1:20), preferred (10:1)-(1:10). The invention has the beneficial effects that: because the azoxystrobin is a methoxyl acrylic compound and the polyoxin is a novel agricultural antibiotic, the azoxystrobin and the polyoxin have different mechanisms of action, different action sites and no cross resistance, and pathogenic bacteria are not liable to generate resistance by mutually compounding the azoxystrobin with the polyoxin; and the pesticide consumption and use cost are reduced due to synergy. The cost is higher when the azoxystrobin is singly used, while the cost is obviously reduced by compounding the azoxystrobin with the polyoxin on the premise that the pesticide effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compound bactericide of azoxystrobin and polyoxin. Background technique [0002] Azoxystrobin (Azoxystrobin) is a new disease management product synthesized through artificial biomimetic synthesis with natural antibiotics derived from mushrooms as the lead compound. It belongs to the methoxyacrylate fungicide, which is highly efficient and broad-spectrum, and has multiple functions of protection, treatment, eradication, penetration and systemic absorption. Azoxystrobin inhibits spore germination and hyphal infection by inhibiting the respiratory production process of pathogenic bacteria, thus causing the pathogenic bacteria to lose their vitality. Azoxystrobin has good crop safety and very outstanding environmental compatibility. [0003] At present, the main products of azoxystrobin preparations include 25% amida suspoemulsion, 325 g / L phenylene ether · azoxystrobin suspens...
