Abstract
The invention relates to a synergy pesticide composition containing penflufen, an effective component comprises an active component A and an active component B, the active component A is penflufen, the active component B is selected from any one of PEIP, fluopicolide, ethaboxam and fluazinam, and the weight ratio of the active component A to the active component B is 1: 80-80: 1. The composition has high activity to a plurality of diseases on a plurality of crops, and has obvious synergy effect and enlarges a sterilization spectrum. The pesticide composition has the characteristics of less drugs dose, rainwater brushing resistance, and obvious synergy.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of synergetic pesticide composition in crop pest of fluorine-containing azoles bacterium aniline.
Technical background
Fluorine azoles bacterium aniline (penflufen): molecular formula is C
18h
24fN
3o, chemical name is 2 ＇-[(RS)-1,3-dimethylbutyl]-5-fluoro-1,3-dimethyl pyrazole-4-formailide, fluorine azoles bacterium aniline is a kind of succinate dehydrogenase inhibitors, mainly acts on respiratory chain electron transmission Complex II, blocks energy metabolism; Can to prevent and treat kind pass, basidiomycetes that soil passes and sac fungi disease, mainly contain potato black scurf, wheat sharp eyespot, rice sheath blight disease, sclerotinia rot of colza etc. that rhizoctonia causes, also have loose smut of wheat, the bunt of wheat, corn southern leaf blight etc.Seed after process can absorb fluorine azoles bacterium aniline in germination process, is transmitted to other positions of plant corpus, plays the effect of cover crop by xylem.
Pyridine bacterium amine, fluopicolide, Guardian or fluazinam all belong to common fungicide, are widely used in the disease of crops.

Table 17 fluorine azoles bacterium aniline and active component B and the composite control grape grey mould test of pesticide effectiveness thereof
As can be seen from Table 17, fluorine azoles bacterium aniline and active component B and composite after effectively can prevent and treat grape grey mould, control efficiency is all more than 97%, be better than the preventive effect of single dose, and the preventive effect phase is long, and grape powdery mildew and downy mildew of garpe can be prevented and treated, in test scope of medication, target crop is had no adverse effects.
Application Example 11:
Fluorine azoles bacterium aniline and active component B and the composite control sclerotinia rot of colza test of pesticide effectiveness thereof, this experimental establishment, at Shaanxi Province's Weinan City Baishui County, is investigated disease index and calculates preventive effect for after dispenser 2 days, 10 days, 30 days respectively.Experimental result is as follows:
Table 18 fluorine azoles bacterium aniline and active component B and the composite control sclerotinia rot of colza test of pesticide effectiveness thereof
As can be seen from Table 18, fluorine azoles bacterium aniline and active component B and composite after effectively can prevent and treat sclerotinia rot of colza, control efficiency, all more than 97%, is better than the preventive effect of single dose, and the preventive effect phase is long, has no adverse effects in test scope of medication to target crop.
After draw through tests different local throughout the country, fluorine azoles bacterium aniline and pyridine bacterium amine, fluopicolide, Guardian or fluazinam composite rear to the multiple diseases in various crop caused by Basidiomycotina, Ascomycotina, Mastigomycotina or Deuteromycotina pathogen if the preventive effect of the diseases such as banded sclerotial blight, stalk break, rust, loose kernel smut, bunt, helminthosporium maydis, powdery mildew, downy mildew, epidemic disease, gray mold, damping off, rice blast or damping off is all more than 97%, be better than single dose preventive effect, synergistic effect is obvious.
