Abstract
The present invention provides a kind of bactericidal composition for preventing and treating muskmelon disease, and active constituent includes carbendazim and fludioxonil, and the weight proportion of carbendazim and fludioxonil is 1:10-10:1.Composition of the invention has notable synergistic effect, can reduce the usage amount of medicament.
Description
Technical field
The invention belongs to agrochemical fields, are specifically related to a kind of bactericidal composition for preventing and treating muskmelon disease.
Background technique
Melon powdery mildew is the important disease for influencing melon yield and quality, can all be occurred in the muskmelon time of infertility, mainly
Cause harm blade, also cause harm petiole and vines when serious.Develop with disease, amyloid plaque color gradually becomes canescence, and the later period occasionally has
Black dot, the withered and yellow necrosis of last disease leaf are generated under bisque.There are generation in melon powdery mildew all parts of the country, and melon patch humidity is big, plant
Strain is easy to happen disease when growing densely, and plants muskmelon in greenhouse, greenhouse and frequently result in muskmelon hundred because sluggish in air circulation
The generation divided.One of the main means of current melon powdery mildew are still using Agro-chemicals control.
It was verified that resistance problem easily occurs in the long-time service of chemical pesticide single dose, dosage is caused to continue to increase, risk
Increase, is unfavorable for Environment Ecological Safe.Seek scientific and rational agriculture chemical compounding, is to solve the problems, such as this preferable method.It will not
Pesticide active ingredient with structure type is compounded, and is current the problems such as solving cost and resistance in pesticide single dose application process
A kind of effective means.Compound synergic is formulated well, can be improved practical control efficiency, be reduced the usage amount of pesticide, facilitate
The generation of delaying drug resistance is the important means of scientific prevention and cure disease.
Summary of the invention
The present invention provides a kind of bactericidal composition for preventing and treating muskmelon disease efficiently, safe.Making for medicament can be effectively reduced
Dosage reduces cost, reduces the harm to environment, and be beneficial to delay the generation of melon powdery mildew drug resistance.
Following technical solution provided by the invention:
A kind of bactericidal composition for preventing and treating muskmelon disease, active constituent include carbendazim and fludioxonil, carbendazim and cough up bacterium
The weight proportion of nitrile is 1:10-10:1.Optimum ratio is 1:7-1:3,10:1.
Also comprising agriculturally acceptable auxiliary agent, the weight percent of active constituent contain in bactericidal composition of the present invention
Amount is 1-60%；It is preferred that 15-25%.
In bactericidal composition of the present invention, the auxiliary agent includes dispersing agent, emulsifier, disintegrating agent, antifreezing agent, disappears
Infusion, wetting agent, filler or solvent.
Bactericidal composition of the invention can be prepared into agriculturally acceptable suitable formulations；Preferred dosage form is wettable powder
Agent, missible oil, water dispersible granules, suspending agent etc..
The bactericidal composition of the present invention is preferred for the anti-of melon powdery mildew for preventing and treating muskmelon disease
It controls.
Compared with prior art, the invention has the following beneficial effects:
It is had obvious synergistic function after bactericidal composition mixture of the invention, improves control efficiency, while
It is conducive to overcome and delay the generation of drug resistance.Present composition medicament mixture reduces dosage, to reduce costs
With alleviate the pollution to environment, safety is good, meets the security requirement of pesticidal preparations.
Specific embodiment
Below with reference to embodiment, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Embodiment 1: the indoor toxicity test of carbendazim and fludioxonil to melon powdery mildew
Subjects: melon powdery mildew (germ picks up from crop field, and Inoculation Method is cultivated)
Experimental pharmacy: carbendazim active compound, fludioxonil raw medicine (commercially available)
Test method: pot-culture method is used.Fresh spores are chosen, after double gauze filters, it is 5*10 that concentration, which is made,5-6*
105The spore suspension of a/ml carries out spray inoculation on growing consistent Muskmelon Seedlings with inoculation sprayer, then carries out
Hot-house culture.Reagent spray processing is carried out after hot-house culture 4 days, is investigated after continuing culture 8 days.
Difference standard: 0 grade: disease-free；1 grade: lesion area accounts for 5% or less full wafer leaf area；3 grades: lesion area accounts for whole
The 6-10% of piece leaf area；5 grades: lesion area accounts for the 11-20% of full wafer leaf area；7 grades: lesion area accounts for full wafer leaf area
21-40%；9 grades: lesion area accounts for 40% or more of full wafer leaf area；
Drug effect calculates: control efficiency=(control disease index-processing disease index)/control disease index * 100%.
It is for statistical analysis with DPS data processing software, the EC50 of each medicament is calculated, then calculates poison altogether by Sun Yunpei's Method
Coefficient (CTC).When CTC≤80, then composition shows as antagonism, and as 80 < CTC < 120, then composition shows as being added
Effect, when CTC >=120, then composition shows as synergistic effect.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100；Theoretical toxicity index (TTI)
In=A medicament toxicity index × mixture in percentage composition+B medicament toxicity index × mixture of A B percentage composition；Co-toxicity coefficient
(CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
The The Toxicity Determination result of 1 carbendazim of table and fludioxonil to melon powdery mildew
As shown in table 1, in bactericidal composition of the invention: the weight ratio of carbendazim and fludioxonil is in 1:10,1:1-7:1 model
In enclosing, co-toxicity coefficient is between 80-120, and composition shows summation action；The weight ratio of carbendazim and fludioxonil is in 1:7-1:
3, within the scope of 10:1, co-toxicity coefficient is all larger than 120, i.e. composition shows as synergistic effect to melon powdery mildew.
Embodiment 2: the field efficacy of carbendazim and fludioxonil to melon powdery mildew
Test method: test carries out in the greenhouse, and test sets 6 processing, 4 repetitions of every processing, and cell random alignment is adopted
Spraying treatment is carried out with conventional nebulizers, for applying medicine three times, 7 days investigation state of an illness after last time medicine.5 points of every cell diagonal line takes
Sample, 10 representational blades of every selection, grade scale and calculation method are referring to embodiment 1.
The field efficacy measurement result of 2 carbendazim of table and fludioxonil to melon powdery mildew
As shown in table 2, in bactericidal composition of the invention, carbendazim and fludioxonil is applied in combination and is remarkably improved it and prevents
Effect is controlled, the dosage of active constituent is reduced, mitigates environmental pollution, field observation is to crop safety.
Any modification made all within the spirits and principles of the present invention, equivalent replacement and improvement etc., should be included in
Within protection scope of the present invention.
