Problems solved by technology

[0006] Although pyrithrimolsulfonate has good systemic absorption and conductivity, its bactericidal spectrum is relatively narrow, and the single use cost is high. Long-term use will not only increase the cost, but also increase the risk of resistance

Abstract

The invention relates to a boscalid and bupirimate-containing sterilizing composition and the application thereof. The composition contains boscalid and bupirimate, and the weight ratio of the boscalid to the bupirimate is 1- 50 to 1-40. The composition can be used for preventing and treating diseases of crops such as cereal crops, fruits or vegetables. The composition has a wide application rangeand good effects, is low in cost and residue, and is safe to people, livestock, the environment and the like.

Description

technical field [0001] The invention relates to a fungicidal composition and its application, in particular to a fungicidal composition containing boscalid and pyrimethrin, which is mainly used for the prevention and treatment of crop diseases. Background technique [0002] Boscalid (cas number: 188425-85-6) is a nicotinamide systemic fungicide with a wide bactericidal spectrum and is active against almost all types of fungal diseases. , Sclerotinia and various rot diseases are very effective, and are mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, vegetables and field crops. Because of its unique mechanism of action, it is not easy to produce cross-resistance, and it is safe for crops and the environment. Its institutions are as follows: [0003] [0004] Bupirimate (Bupirimate, Cas No. 41483-43-6) is a pyrimidine systemic fungicide with protective and therapeutic effects. It can be quickly absorbed by plant roots, stems...
