Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, the especially bactericidal composition of a kind of 2-cyano-3-amino-3-phenylancryic acetate-containing and Mancozeb
And its application.
Background technology
2-cyano-3-amino-3-phenylancryic acetate, outward appearance is white powder, molecular formula:C12H12N2O2, chemical name:2- cyano group -3- amino -3-
Ethyl phenylacrylate.
2-cyano-3-amino-3-phenylancryic acetate belongs to 2- cyanoacrylate antibacterial, is a kind of unique new type bactericide of model of action, to reaping hook mushroom
Effectively, the bakanae disease of rice that especially causes to the microbial head blight of reaping hook, fusarium moniliforme, fusarium oxysporum draw for the disease that causes
The tomato wilt for rising has good prevention effect.2-cyano-3-amino-3-phenylancryic acetate is absorbed by root, has translocatable upwards, face on blade
To blade bottom and interlobate translocatable poor.
Mancozeb (Mancozeb), chemical name:The coordination network of ethylene bisdithiocarbamic manganese and zinc ion
The polycomponent coordination compound of compound or ethylidene dithiocarbamate manganese and zinc salt.Mancozeb is mainly used in preventing and treating
The multiple diseases that the Phytophthora of Phycomycetes, the Cercospora of Fungi Imperfecti, Ascochyta etc. cause.To on fruit tree, vegetable
Anthrax, the disease such as early blight it is effective.
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 is to provide a kind of applied widely, low cost, effect good 2-cyano-3-amino-3-phenylancryic acetate-containing for above-mentioned technical problem
With the plant bactericidal composition of Mancozeb.

(1) indoor biometricses test:
Mycelial growth rate method is adopted indoors, determines different agents to capsicum epidemic disease bacterial strain (Phytophthora capsici
Leonian EC)50Value, using co-toxicity coefficient computational methods, calculates the co-toxicity coefficient (CTC) of mixture, determines mixture
Building performance, 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, 2-cyano-3-amino-3-phenylancryic acetate and Mancozeb weight ratio are 1~70:1~50 compositionss are altogether
Malicious coefficient is both greater than 120, has obvious synergistic function to phytophthora capsici.
(2) field control effectiveness test:
Carried out preventing and treating capsicum epidemic disease test with pesticidal preparations 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 pesticide single dose 25% 2-cyano-3-amino-3-phenylancryic acetate SC and 50% Mancozeb WP and blank clean water experiment.
2nd, each plot area of test method is 66.7m2, it is repeated 3 times;Investigation drug effect method after investigating and prevent and treat before dispenser
For:5 points of randomization (takes 5m per in the test process area2), 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 2-cyano-3-amino-3-phenylancryic acetate+Mancozeb different ratio to capsicum epidemic disease
As shown in Table 2:Compared with single dose, 2-cyano-3-amino-3-phenylancryic acetate has significant effect, energy with Mancozeb compositionss to capsicum epidemic disease
Produce higher synergistic function.The consumption of the amount ratio independent reactive compound of bactericidal composition is substantially reduced, i.e. mixture
Activity more than independent component activity, compared with single dose, reduce preventing and treating recruitment, drug cost.
Shown by indoor biometricses and field efficacy result, 2-cyano-3-amino-3-phenylancryic acetate there is obvious Synergistic to make with Mancozeb compositionss
With the prevention effect of compositionss is excellent, and prevention effect is better than single dose kind, in agricultural application has using value.
