Abstract
The invention discloses a sterilization composite whose effective activity components are comprise flutriafol and triflumizole in a weight ratio of 1-60 to 60-1. Auxiliary agent and excipient are added into the effective activity components to prepare wettability powder, water-dispersion granule and suspending agent. The sterilization composite is mainly used for preventing and curing powdery mildew, cladosporium cucumerinum and alternaria leaf spot of grain, vegetable and fruit trees.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains Flutriafol and fluorine bacterium azoles and be used to prevent and treat powdery mildew, scab, spot defoliation.
Technical background
Flutriafol (flutriafol) is the triazole bactericidal agent that American Cyanamid Company produces.Molecular formula: C16H13F2N30, chemical name: α-(2-fluorophenyl)-α-(4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol.
Flutriafol belongs to triazole bactericidal agent, has interior absorption, in plant corpus, conducts, and disease is had protection and therapeutic action.Can prevent and treat the cereal crop powdery mildew, Helminthosporium, Puccinia, shell pin Pseudomonas pathogen also can be cooked seed treatment, prevents and treats soil-borne disease and seed-borne disease.The cereal powdery mildew there is special efficacy.
Fluorine bacterium azoles (triflumizole), structural formula are (E)-4-chloro-α, α, α-three fluoro-N-(1-imidazoles-1-base-α-third oxygen ethylidene) neighbour-toluidines fluorine bacterium azoles, molecular formula: C
15H
15N
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.
A kind of agricultural chemicals uses on a kind of disease repeatedly, and through after the regular hour, drug effect just obviously goes down, even nearly unavailable, this phenomenon, the sick exactly pesticide resistance that produced.Drug-fast generation forces the vegetable grower to have to increase dose and medication number of times, has formed a kind of pernicious upgrading phenomenon so again just.After receiving 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.At present, no matter be Flutriafol, fluorine bacterium azoles etc. or other efficient germicides, along with a large amount of single uses, control efficiency is unsatisfactory.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, Flutriafol and fluorine bacterium azoles be 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 the bactericidal composition that relevant Flutriafol and fluorine bacterium azoles are composite up to now as yet.
Summary of the invention
