Application of 1,5-diaryl-3-trifluoromethylpyrazoles in the control of agricultural fungal diseases
ActiveCN108849912BBroad-spectrum bactericidal activityGood control effectBiocideFungicidesFungicideFungal disease
The invention belongs to the technical field of pesticides, and particularly relates to application of 1,5-diaryl-3-pyrazole compound in prevention and control of agricultural fungal diseases. The general structural formula of the 1,5-diaryl-3-pyrazole compound is as shown in the description, wherein R1 is selected from fluorine, methoxyl or methyl; and R2 is selected from -CHOOH, -SO2NH2, -NO2, -F,-C1 or -Br. Compared with a traditional agricultural fungicide, the 1,5-diaryl-3-pyrazole compound provided by the invention is unique in structure, adopts an action mechanism different from that ofa traditional fungicide, and has no cross resistance risks on resistance strains generated by an existing fungicide.
