Description
Technical field
The present invention relates to the bactericidal composition of a kind of bactericidal composition and application thereof, especially a kind of 2-cyano-3-amino-3-phenylancryic acetate-containing and Propamocarb 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.
Propamocarb (Propamocarb), chemical name is:3- (dimethylamino) propyl carbamic acid propyl ester, molecular formula:
C9H20N2O2.Structural formula:
Propamocarb belongs to carbamate fungicide, and low toxicity, safety, with preferable local systemic action, process energy after soil
By Root Absorption and it is delivered up to whole plant quickly;After stem and leaf spraying treatment, can be absorbed by blade rapidly and play protection work
With.Its mechanism of action is the synthesis of the phosphoric acid and fatty acid that suppress pathogenic bacteria cell membrane component, suppresses mycelial growth to spread and Sporangium
Formation and spore germination.Propamocarb is a kind of wide-spectrum bactericide, especially effective to Phycomycetes funguses, disk mould to tow stalk
Mould, downy mildew, phytophthora, the rotten funguses such as mould have good killing action.Suitable for Fructus Cucumidis sativi, Fructus Lycopersici esculenti, Fructus Capsici, Caulis et Folium Lactucae sativae, Ma Ling
The various crop such as the vegetables such as potato and Nicotiana tabacum L., Fructus Fragariae Ananssae, flowers, fruit tree.
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

(1) indoor biometricses test:
Mycelial growth rate method is adopted indoors, determines different agents to tomato late blight pathogenic bacteria bacterial strain (Phytophthora
Infestans (Mont.) de Bary) 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.
