Abstract
The invention discloses a sterilization composite whose effective activity components comprise triflumizole and hexaconazole in a weight ratio of 1-60:40-1. Auxiliary agent and excipient are added into the effective activity components to prepare wettability powder, water-dispersion granule, suspending agent, aqua resigen and microemulsion. The invention is mainly used in curing and preventing powdery mildew, cladosporium cucumerinum and alternaria leaf spot.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains fluorine bacterium azoles and own azoles alcohol and be used to prevent and treat powdery mildew, scab, spot defoliation.
Technical background
Fluorine bacterium azoles (triflumizole), structural formula are (E)-4-chloro-α, α, the own azoles alcohol of α-three fluoro-N-(1-imidazoles-1-base-α-third oxygen ethylidene) neighbour-toluidines, molecular formula: C

3ClO.
Fluorine bacterium azoles is by the imidazoles bactericide of Japanese Cao Da company exploitation, is sterol demethylation inhibitor, has the systemic fungicide of protection, treatment and output effect.Be applicable to wheat class, various vegetables, fruit tree and other crops, to crop safety.
Own azoles alcohol (hexaconazole), structural formula are (RS)-2-(2,4 dichloro benzene base)-1-(1H-1,2,4-triazol-1-yl)-own-2-alcohol, molecular formula: C
14H
17Cl

3O.
Own azoles alcohol belongs to sterol demethylation inhibitor, destroys and organize the biosynthesis of the cell membrane important composition composition ergosterol of germ, causes cell membrane not form, and makes germ dead, has interior suction, protection and therapeutic activity.Can effectively prevent and treat disease due to sac fungi, basidiomycetes and the imperfect fungus, like powdery mildew, scab, brown spot, anthracnose etc.
No matter be fluorine bacterium azoles or own azoles alcohol, still other efficient germicides singlely use on a kind of disease repeatedly, and through after the regular hour, drug effect just obviously goes down, even nearly unavailable, and this phenomenon is be exactly germ has produced pesticide resistance.Drug-fast generation forces the peasant to have to increase dosage and medication number of times, has formed a kind of pernicious upgrading phenomenon so again just.After germ receives the doses action of agricultural chemicals, the death that has, wherein insensitive individuality is just survived; And raise up seed, such offspring's pesticide resistance is just stronger, for preventing and treating the disease that develops immunity to drugs on the agricultural; A kind of method is to release the new component that new and existing kind do not have cross resistance; But the new component development cost is high, and the construction cycle is long, and the speed that develops immunity to drugs less than disease forever; Additive method such as crop allocation adjustment etc. are difficult to play obvious effects in actual mechanical process.Adopting the agriculture chemical compounding of two kinds of different sterilization mechanisms is good prescriptions, owing to obviously improved preventive effect, and reduced dosage, and different classes of active ingredient application point is also different, thereby has delayed the generation of disease drug resistance greatly.
Draw according to the test of pesticide effectiveness repeatedly, prescription screening report, fluorine bacterium azoles and own azoles be pure composite to have good synergistic effects, has obviously improved control efficiency, is the important means of integrated control powdery mildew, scab, spot defoliation.
Do not see the report of relevant fluorine bacterium azoles and own azoles alcohol combination sterilization composition up to now as yet.
