Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of efficient bactericidal composite on crop pest containing benzene oxygen quinoline and triazole type.
Technical background
The chloro-4-quinolyl of benzene oxygen quinoline (Quinoxyfen) chemical name: 5,7-bis--4-fluorophenyl ether, molecular formula: C
15h
8cl
2fNO.Benzene oxygen quinoline is systemic fungicide, and has the vapor phase activity, contributes to like this reallocation of medicament whole plant.Benzene oxygen quinoline is the growth signals agent interfering.Research shows, it is not neither the sterol biosynthesis inhibitor is again dhodh inhibitors.This product is protective fungicide, and mobility is good, can suppress the appresorium growth, does not have eradicant action.
The triazole bactericidal agent sterilization wide spectrum-many kinds of disease funguses of sac fungi, basidiomycetes, imperfect fungus are had to very high activity, but to the oomycetes non-activity; Efficiently-drug effect is high, dosage reduces; Lasting period length-blade face 15-20 days, seed treatment is about 80 days, and soil treatment 100 days is all long than general bactericide, and extends with the increase of dosage; Interior suction transporting is good, and infiltration rate is fast, dispenser after 2 hours the absorbed amount of triazolone can suppress the growth of powdery mildew; There is strong preventive effect, therapeutic action preferably, stifling and eradicant action.The mechanism of action, for to affect the sterols biosynthesis, is damaged somatic cells film function.
In the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the generation of disease drug resistance.The different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, discovery is mutually composite by benzene oxygen quinoline and Cyproconazole, penconazole, Flusilazole, Tebuconazole, prothioconazoles, good synergistic effect is arranged within the specific limits, and relevant composite about benzene oxygen quinoline and Cyproconazole, penconazole, Flusilazole, Tebuconazole, prothioconazoles, there is not yet relevant report at present at home and abroad.
