Abstract

The invention discloses a germicidal composition containing bromothalonil and copper preparation. The composition comprises an active component A bromothalonil and an active component B selected from any of the following copper preparations: copper 8-hydroxyquinolinate, Cupravit, copper(succinate+glutarate+adipate) and cupric acetate, wherein the weight ratio of the component A and component B ratio is 1:80-80:1. The composition provided by the invention has synergism on a plurality of insects harming agricultural production, reduces drug dose of pesticide, reduces residual quantity of pesticide on crops, mitigates environmental pollution, is safe for human and livestock, has good compatibility and does not cause resistance on insects.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing bromothalonil and a copper preparation on crop diseases. Background technique [0002] Bromothalonil (bromothalonil) molecular formula: (C 6 h 6 Br 2 N 2 ), a broad-spectrum, low-toxicity, mildew-proof, algae-killing fungicide. It can inhibit and eradicate the growth of bacteria, fungi and algae, and is suitable for anti-corrosion and anti-mold of textiles and leather, and algae-killing of industrial water. It has a good control effect on crop diseases, especially for anthracnose. [0003] Copper quinoline, copper rosinate, copper succinate, and copper acetate are all copper preparations, which are widely used in crop diseases. In addition, other copper preparations such as copper thisonate, copper rosinate, and copper hydroxide can also be used with bromothalinil For compounding. [0004] However, in the actual proce...
