Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, especially a kind of bactericidal composition containing benzene metsulfovax and Cyproconazole
And its application.
Background technology
Benzene metsulfovax (benthiavalicarb-isopropyl), molecular formula：C18H24FN3O3S, chemical name：[[(6- fluorobenzene is simultaneously
Thiazol-2-yl)-ethylaminocarbonyl] -2- methyl-propyls] carbamic acid isopropyl ester.
Benzene metsulfovax have good bactericidal activity to phytophthora root rot, to its sporangial formation, sporangial sprouting at low concentrations
There is good inhibiting effect, but the release to zoospore and the movement of zoospore are not acted on.In field test, benzene thiophene bacterium
Amine is with relatively low dosage (25～75g a.i./hm2) can effectively control late blight, grape and other crops of potato and tomato
Downy mildew.
Cyproconazole (Cyproconazole), chemical name is：2- (4- chlorphenyls) -3- cyclopropyl -1- (1H-1,2,4- triazol-1-yls) fourth
- 2- alcohol, molecular formula：C15H18ClN3O.Structural formula：
Cyproconazole is a kind of triazole type disinfectant use in agriculture, and the mechanism of action is to suppress sterol demethylation, is made with prevention and treatment
With having been widely used for pesticide field at present, to the Erysiphales on cereal crop, coffee, beet and fruit tree, rest fungus
Mesh, Cercospora, beak genuss, Septoria, Venturia bacterium are effective.Prevent and treat cereal and coffee rust, cereal, fruit tree
Powdery mildew etc., Cyproconazole are mixed with other bactericide, can preferably prevent and treat all kinds of leaf spots and net blotch.
The difficulty of prevention and cure of phytopathogen is increasing at present, on the one hand, with economy such as the change of pattern of farming, melon fruits and vegetables
Crops planting area progressively expands, and disease occurrence degree, generation quantity increase, and in preventing and treating, difficulty is increased；The opposing party
Face, the resistance of pathogen rise under lasting medicament selection pressure year by year, and the prevention effect of single dose is had a greatly reduced quality, plant disease
Preventing and treating is faced with significant challenge.
The content of the invention
The purpose of the present invention be for above-mentioned technical problem provide a kind of applied widely, low cost, effect it is good containing benzene metsulfovax
With the plant bactericidal composition of Cyproconazole.
The purpose of the present invention is realized by following measures：

Indoor biometricses are tested：
Mycelial growth rate method is adopted indoors, determines different agents to cucumber downy mildew bacterial strain (Pseudoperonospora
Cubensis (Berk.et Curt.) Rostov.) EC50Value, using co-toxicity coefficient computational methods, calculates the co-toxicity coefficient of mixture
(CTC), determine the building performance of mixture, circular is as follows：
With in mixture, a certain single dose (generally selects EC as standard agent50Junior), calculated：
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × the B of the toxicity index of theoretical toxicity index=A single doses × A single doses proportion+B single doses in mixture is mono-
Agent proportion in mixture
The EC of actual measurement toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
Co-toxicity coefficient is classified：When CTC is more than 120, mixture has synergetic, and CTC exists for antagonism, CTC when being less than 80
It is summation action between 80-120.

1 indoor biometricses of table test result indicate that, benzene metsulfovax and Cyproconazole weight ratio are 1～70：1～50 composition is altogether
Malicious coefficient is both greater than 120, has obvious synergistic function to bacterium of downy mildew of cucumber.
Field control effectiveness test：
Agent preventing and treating cucumber downy mildew test is carried out with agricultural chemicals system obtained in above-described embodiment.
1st, test process：This test medicine consumption sets three concentration for the treatment of, comparison medicament point respectively according to the difference of each composition
It is not 15% benzene metsulfovax WP of agricultural chemicals single dose and 40% Cyproconazole WP and blank clean water experiment.
2nd, test method：Each plot area is 66.7m2, it is repeated 3 times；Investigation drug effect side after investigating and prevent and treat before dispenser
Method is：5 points of the grab sample in the test process area (takes 5m per2), the state of an illness is carried out according to national field test relevant criterion
Classification, calculates preventive effect.
3rd, result of the test see the table below：
Table 2：Field efficacy result of the benzene metsulfovax+Cyproconazole different ratio to cucumber downy mildew
As shown in Table 2：Compared with single dose, benzene metsulfovax and Cyproconazole composition have significant effect to cucumber downy mildew,
Higher synergistic function can be produced.The consumption of the amount ratio independent reactive compound of bactericidal composition is substantially reduced, that is, mix
Activity of the activity of thing more than independent component, compared with single dose, reduces preventing and treating recruitment, drug cost.
Shown by indoor biometricses and field efficacy result, benzene metsulfovax there is obvious Synergistic to make with Cyproconazole composition
With the prevention effect of composition is excellent, and prevention effect is better than single dose kind, in agricultural application has using value.
