Abstract
The invention discloses a sterilization composite whose effective activity components comprise triflumizole and tebuconazole; wherein the weight ratio of triflumizole and tebuconazole is 1-60:60-1; and 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, leafspot and alternaria leaf spot of crops.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains fluorine bacterium azoles and Tebuconazole and be used to prevent and treat powdery mildew, leaf spot, spot defoliation.
Technical background
Fluorine bacterium azoles (triflumizole), structural formula are (E)-4-chloro-α, α, α-trifluoro N-(1-imidazoles-1-base-α-third oxygen ethylidene) neighbour-toluidines Tebuconazole, molecular formula: C
15H

3F
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.
Tebuconazole (tebuconazole), structural formula be (RS)-1-right-chlorphenyl-4,4-dimethyl-3 (1H-1,2,4-triazol-1-yl methyl) amylalcohol, molecular formula: C
16H
22ON
3Cl.
Tebuconazole belongs to the sterol biosynthesis inhibitor, can be is rapidly partially absorbed and mainly shifts to the top by plant is vegetative, not only has bactericidal activity, also can promote plant growth, makes it well developed root system, leaf look dark green, robust plant, thereby improves output.Tebuconazole is mainly used in the disease that control Erysiphe, Puccinia, nuclear cavity Pseudomonas etc. cause.
No matter be fluorine bacterium azoles or Tebuconazole, 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 Tebuconazole be composite to have good synergistic effects, has obviously improved control efficiency, is the important means of integrated control powdery mildew, leaf spot, spot defoliation.
Do not see the report of the bactericidal composition that relevant fluorine bacterium azoles and Tebuconazole are composite up to now as yet.
Summary of the invention
