Abstract
The invention belongs to the technical field of pesticides and specifically relates to a bactericidal composition containing octyl trichlamide and carbendazim and application of the bactericidal composition in preventing fungal diseases of crops. In the composition, a weight ratio of the octyl trichlamide to the carbendazim is 20:1-1:20. The bactericidal composition achieves synergism through compounding, is wide in scope of application, low in cost, good in effect, and capable of being widely applied to soil treatment, leaf surface spraying, and the like, and can be mixed with water to form paste for mainly preventing and treating fruit tree canker.
Description
Technical field
The invention belongs to the technical field of agricultural chemicals, be specifically related to a kind ofly contain pungent bacterium amine and carbendazim carries out composite bactericidal composition, and the application aspect control farm crop fungus, bacterium, virus disease.
Background technology
Pungent bacterium amine is a kind of environment-friendly type amino acids high molecular polymer bactericide, containing synergy composition organosilicon and mew class sterilization factors, high-tech of new generation, environment-friendly type, high-efficiency broad spectrum, low toxicity bactericide, resistance old brand bactericide being produced for crop pest, special development, formula uniqueness, superpower infiltration, 3-10 killing fungus in second, bacterium and virus, can penetrate rapidly the cell membrane of virus, fungi, bacterium, directly enter in pathogen cell, progressively dissolve the respiratory system of pathogen.Thoroughly root out pathogen working condition, and the energy impaired position of rapid healing, stem, leaf, fruit face plant after dispenser form diaphragm, stop germ subintrusion again.Half-and-half know, the killing rate of four subphylum class fungies such as load, flagellum, ascus, bacterium, virus is all more than 98%, has fabulous prevention, treats, roots out effect, long-term use does not produce resistance.
Carbendazim has another name called carbendazol, carbendazol.Carbendazim is a kind of broad-spectrum germicide, and the disease that various crop is caused by fungi (as imperfect fungus, many sac fungis) has control efficiency.Can be used for foliar spray, seed treatment and soil treatment etc.Carbendazim is high-efficiency low-toxicity systemic fungicide, has interior suction treatment and protective effect.Disturb the formation of spindle in pathogen mitosis, affect cell division, play bactericidal action.
Above-mentioned two kinds of component mechanism of action are different, cooperatively interact and have good control efficiency for soil disease, and cost performance is high, are applicable to extensively promoting.This formula also has unique advantage on control fruit tree putrefaction disease.
Summary of the invention
The object of the invention is to provide a kind of for the problems referred to above and carry out composite bactericidal composition and application thereof by pungent bacterium amine and carbendazim, said composition plays synergistic effect by composite, applied widely, cost is low, effective, can be used to prevent and treat common fungoid on the crops such as vegetables, fruit tree, paddy rice, bacillary, Disease as rice blast, rice sheath blight disease, apple scab, apple canker, Pear black spot, citrus anthracnose, citrus scab, damping off, damping off etc.
In the present invention, pungent bacterium amine, the weight of carbendazim, the weight of active ingredient etc. mentioned, all refer to the weight after folding hundred, i.e. the weight of active principle.
Bactericidal composition containing pungent bacterium amine and carbendazim of the present invention, its active ingredient consists of pungent bacterium amine and carbendazim, and described pungent bacterium amine and the weight ratio of carbendazim be, pungent bacterium amine: carbendazim=20:1～1:20.
As preferably, described pungent bacterium amine and the weight ratio of carbendazim be, pungent bacterium amine: carbendazim=5:1～1:5.
Wherein, in said composition, the weight percentage of active ingredient is 1%～90%.
Said composition formulation comprises wetting powder, suspending agent, adds auxiliary agent, film forming agent and excipient, and the production technology of all knowing according to those skilled in the art can be made into required formulation.
This bactericidal composition is for preventing and treating the fungal disease on crop, for preventing and treating common fungoid on the crops such as vegetables, fruit tree, bacillary, Disease as rice blast, rice sheath blight disease, apple canker, Pear black spot, citrus anthracnose, citrus scab, damping off, damping off etc.
Beneficial effect of the present invention is: pungent bacterium amine and two kinds of bactericide of carbendazim are carried out composite, because the mechanism of action between the two is different, pungent bacterium amine is a kind of environment-friendly type amino acids high molecular polymer bactericide, containing synergy composition organosilicon and mew class sterilization factors, be high-tech of new generation, environment-friendly type, high-efficiency broad spectrum, low toxicity bactericide, can dissolve the respiratory system of pathogen.Carbendazim is to disturb in pathogen mitosis to spin cone formation, suppresses mitosis.Combine and expanded fungicidal spectrum, thereby applied widely, composite composition has synergistic effect in certain proportion, not only control efficiency is good, reduce dosage and drug cost, reduced the harmful effect to environment, and greatly delayed the drug-fast generation of germ.This bactericidal composition, can be used to prevent and treat common fungoid on the crops such as vegetables, fruit tree, bacillary, Disease as rice sheath blight disease, apple scab, apple canker, damping off, damping off, tomato virus disease etc.
In a word, combination sterilization composition of the present invention, has obvious economic benefit and environmental benefit.
The indoor virulence of the composite mixture of having studied pungent bacterium amine and the different proportionings of carbendazim with mycelial growth rate method to Valsa mali, experimental technique adopts the abundant method of Sun Yun to calculate co-toxicity coefficient (CTC) and evaluates mixed effect, CTC value is greater than 120 o'clock mixtures and has synergistic effect, being less than at 80 o'clock is antagonism, has summation action in the time of between 80～120.
Concrete grammar is as follows:
Get the liquid preparing and be placed in 100ml 50-60 ℃ of PDA sterilising medium, shake up, pour in the sterilizing culture dish of diameter 60 mm, after cooled and solidified, move respectively the bacterium cake that length is consistent, diameter is 4mm of delivering a child, using and add the sterilising medium of equivalent coordinative solvent as blank, all operations all carries out sterile working at superclean bench, and 3 repetitions are established in every processing.Put into 27 ℃ of constant incubators and cultivate after 3-8 days, adopt right-angled intersection method to measure colony diameter, calculate bacteriostasis rate, EC
50, the relevant parameter such as CTC, relevant calculating formulas is as follows:
Pure amount of growth=bacterium colony average diameter-bacterium cake diameter (0.4cm)
Bacteriostasis rate=[the pure amount of growth of (contrast pure amount of growth-process pure amount of growth) * 100/ contrast] * 100%
The EC50*100 of the EC50/B agent of toxicity index TI(B)=standard agent A
The EC50*100 of the EC50/AB of actual toxicity index ATI (AB)=A
The percentage of percentage+TI (B) the * B of theoretical toxicity index TTI (AB)=TI (A) * A in mixture in mixture
Co-toxicity coefficient CTC=ATI(AB)/TTI(AB) * 100
The pungent bacterium amine of table 1 and the toxicity test table of carbendazim list mixture to Valsa mali
| Reagent agent | Active ingredient weight ratio | EC50（mg/L） | Co-toxicity coefficient (CTC) |
| Pungent bacterium amine | —— | 19.68 | —— |
| Carbendazim | —— | 1.09 | —— |
| Pungent bacterium amine: carbendazim | 20:1 | 2.52 | 178.83 |
