Problems solved by technology

Due to the lack of resistant varieties in production, chemical pesticide control is still an important measure to control diseases, but the long-term single use of a certain pesticide, the continuous increase in the frequency and dosage of medication, lead to the problem of pesticide resistance

Abstract

The invention discloses a pesticide composition containing phenycomycin and bromothalonil. The pesticide composition is characterized in that effective active components include the phenycomycin and the bromothalonil, the weight ratio of the phenycomycin to the bromothalonil ranges from 1:30 to 20:1, and the weight percentage content of the phenycomycin and the bromothalonil accounts for 1-50% ofthe composition. A preparation method of the pesticide composition and an application of the pesticide composition to plant anthracnose control particularly have good effects in control of watermelonanthracnose and cucumber anthracnose.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a pesticide composition containing phenethycin and bromothalonil. Background technique [0002] Plant anthracnose is a major disease that often occurs in crops. It mainly damages the leaves of plants, and sometimes also damages stems and twigs. When the damage is serious, it even causes the death of crops. Plant anthracnose is very stubborn, and it is a disease hated by farmers' friends. At present, domestic and foreign research on anthracnose bacteria mostly focuses on the causes and laws of the disease, and some have gone deep into the molecular level. Due to the lack of resistant varieties in production, chemical pesticide control is still an important measure to control diseases, but the long-term single use of a certain pesticide, the increasing frequency and dosage of medication, lead to the problem of pesticide resistance. [0003] Phenethylmycin, chemical ...
