Description
Technical field
The invention belongs to the composition pesticide field, is the bactericidal composition of active ingredient with two azoles of phenylate and cyprodinil specifically, and the purposes of said composition in control fruit tree, eliminating vegetable botrytis.
Background technology
Gray mold is a kind of fungal disease of the common and difficult control of open country, protection ground crop, belongs to low temperature and high relative humidity type disease, and the pathogen growth temperature is 2～30 ℃, and it is the disease high-incidence season when above that 20～25 ℃ of temperature, humidity continue 90%.Due to gray mold is infected by the Botrytis cinerea bacterium, belong to fungal disease, flower, really, leaf, stem all can fall ill.Fruit is caught an illness, and Chinese olive is injured heavily, and residual column cap or petal are many to be infected earlier; The back causes pericarp to be canescence to the fruit expansion, and the mould layer of thick grey is arranged; Be the rotten shape of water, the blade morbidity begins from blade tip, along becoming " V " shape inwardly to expand between vein; Taupe, limit have the alternate line shape line of the depth, and sick key has a common boundary clearly demarcated.This disease is a kind of typical aeroborne disease, can propagate with air, current and farming operation.In actual disease control process, be difficult to adopt an effective measure and thoroughly cut off source of infection; Under the situation that pathogen is invaded, also be difficult to utterly destroy pathogen, spray like medicament, be difficult to solve the pathogen in air and the dew; And smoked separately canopy can not solve on the invalid bodies such as disease leaf, sick fruit or inner pathogen by emphasis.The sick seedling look of gray mold is shallow, and blade, petiole morbidity are canescence, water stain shape, and organization softening is to rotten, and there is grey mold on the surface during high humidity.Children's stem is many at the nascent irregular water logging spot of petiole base, and very fast deliquescing is rotted, and hangs to contract or roll over, and last sick scutellum rot is withered and died of illness.
The two azoles of phenylate (English common name: Difenodiconazole), chemical name: 2-[2-chloro-4-(4-chlorobenzene oxygen) phenyl]-1, two (1H-1,2,4-the triazol-1-yl)-2-propyl alcohol of 3-.Application number is chemical structural formula, preparation method and the sterilizing use that discloses the two azoles of phenylate in 200610140836.7 the one Chinese patent application, at this this patent application is incorporated herein by reference in full.The two azoles of phenylate have following structural formula:

Regulation with reference to medicine inspecting institute of the Ministry of Agriculture " GB/T 17980.28-2000 pesticide field efficacy medicine test criterion ()---bactericidal agent for preventing and treating eliminating vegetable botrytis "; The sub-district of test medicine, contrast medicament and blank is handled and is adopted district's group arrangement at random, sub-district area 20m
2, 4 repetitions, this test amounts to dispenser three times.For the first time be administered to grape and bloomed preceding 6 days, fruit phase, each dispenser of fruiting period just 1 time, 7 ~ 10 days at interval.5 samplings are adopted in every experimental plot, every some investigation 2 strains.The sick progression of investigation fruit ear number, morbidity fruit ear number and fruit ear calculates disease index.
The disease grade scale is following:
0 grade: full fruit (fringe) is anosis;
1 grade: fruit grain (fringe) below 1/4 rots;
2 grades: 1/4～1/2 fruit grain (fringe) rots;
3 grades: 1/2～3/4 fruit grain (fringe) rots;
4 grades: fruit grain (fringe) rots more than 3/4.
The drug effect computational methods:
According to investigation result, calculate disease index and preventive effect according to following (1), (2) formula.
In the formula: CK

Table 4 control grape grey mould field control effectiveness test result
Comprehensive above-mentioned indoor biometrics and field control effectiveness test result show that the beneficial effect that bactericidal composition according to the invention produces is:
(1) compare with single agent, this bactericidal composition has significant synergistic effect to disease, has improved bactericidal effect;
(2) reduce the medication number of times, lower drug cost, reduce environmental pollution and residue of pesticide;
(3) composition is made up of the active ingredient of different effects mechanism, and the action site increase helps overcoming and delays the drug-fast generation of germ.The present composition does not all have obvious harmful effect to trial crops, and leaf look, growing way etc. are all normal, and safety is good, meets the security requirement of pesticidal preparations.
Bactericidal composition according to the invention has good preventive effect to fruit tree and eliminating vegetable botrytis.
