Abstract
The invention relates to a bactericidal composition containing famoxadone and boscalid, wherein the mass ratio of famoxadone to boscalid is (5:1)-(1:5). The pesticide composition provided by the invention is suitable for controlling strawberry powdery mildew diseases; and the bactericidal composition provided by the invention has an obvious synergistic effect, can reduce the used amount of pesticides, and has great economic and social benefits for popularization and application.
Description
Technical field
The present invention relates to a kind of bactericidal composition, active ingredient is nitre benzene bacterium ester and Boscalid, is applicable to prevent and treat powdery mildew of strawberry.
Background technology
Nitre benzene bacterium ester is methoxy acrylic bactericide, and to powdery mildew special efficacy, nitre benzene bacterium ester is close ester compound, plant leaf blade surface can rapidly and blade surface wax coat combination, resistance to rain, have the lasting period grow etc. feature.
Boscalid is Novel tobacco acid amide fungicides; fungicidal spectrum is wider; almost there is activity to all types of fungal disease; shifted in plant by blade face infiltration, suppress mitochondrial succinate acid esters dehydrase, hinder tricarbonic acid cycle; make amino acid, sugar lacks, energy reduces; the division of interference cell and growth, have neural activity to disease, has protection and therapeutic action.Suppress spore germination, the extension of bacterium pipe, mycelial growth and spore mother cell to form the Main Stage of conk and breeding, bactericidal action is directly caused by parent active agent, does not have corresponding metabolic activity.Be mainly used in preventing and treating powdery mildew, gray mold, stalk break and various rots etc., and also effective to the resistance bacterium of other medicaments, for comprising the control of the diseases such as rape, grape, fruit tree, vegetables and field crop.
Powdery mildew of strawberry is commonly called as " flower pedopathy ", is infected by Rhizoctonia solani Kuhn to fall ill, how occurs under high temperature, super-humid conditions.Banded sclerotial blight causes harm seriously in South Rice Region of China, is one of Major Diseases on current strawberry production.The scab ellipse of leaf sheath, blade or Colaesce are the large spot of moire shape, and time moist, scab is blackish green, moistening shape.Scab edge dark brown time dry, middle part olive drab(O.D), to canescence, causes leaf sheath and blade is withered eventually.Especially occur the most general with the high yield field of dense planting hybrid rice of short stem and seriously, the withered strawberry ripening rate that causes of blade reduces, and thousand kernel weight alleviates, and generally causes damage 10 ~ 20%, notably can reach more than 50%.
The mixture of different pesticide species is the common methods of control agricultural pest.Being screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the drug-fast generation of damage by disease and insect, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to nitre benzene bacterium ester and Boscalid conducts in-depth research, and finds that nitre benzene bacterium ester and Boscalid carry out mixture and have obvious synergistic effect in certain mixed ratio scope to powdery mildew of strawberry, after further study, completes the present invention.
Composition and the application of nitre benzene bacterium ester and Boscalid there is no report at present.
Summary of the invention
The object of the invention is to: the bactericidal composition for preventing and treating powdery mildew of strawberry developing a kind of efficient, low toxicity, safety, environmental protection.
For achieving the above object, the technical solution adopted in the present invention is: a kind of bactericidal composition containing nitre benzene bacterium ester and Boscalid, with nitre benzene bacterium ester and Boscalid for active ingredient, the ratio of quality and the number of copies of nitre benzene bacterium ester and Boscalid is 5:1 ~ 1:5, nitre benzene bacterium ester and Boscalid weight summation in the composition percentage by weight are 5% ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
The auxiliary element used in bactericidal composition of the present invention comprises wetting agent, stabilizing agent, dispersant, disintegrant, thickener, pH adjusting agent, defoamer, antifreezing agent, filler etc., be all auxiliary agent conventional in Pesticide formulation, concrete composition and consumption are determined by test according to recipe requirements.
Bactericidal composition of the present invention according to well known to a person skilled in the art method, can be processed into the application forms that the applicable agricultural productions such as suspending agent, wetting powder, water dispersible granules use.
Bactericidal composition provided by the invention, usually adopts and is watered spray method use, also can adopt other operation techniques agriculturally applied as required.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.
The frequency of administration of bactericidal composition of the present invention and amount of application change with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Bactericidal composition provided by the invention has the following advantages:
1, bactericidal composition provided by the invention, in certain ratio range, show obvious synergistic effect to powdery mildew of strawberry, the control efficiency of composition is significantly improved than single dose, reduces the using dosage of agricultural chemicals, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope.
2, two kinds of effective ingredient mechanism of action of bactericidal composition provided by the invention are different, can overcome the single shortcoming making with medicament easily produce resistance for a long time, extend the service life of medicament, to the comprehensive regulation important in inhibiting of disease.
3, the bactericidal composition provided of the present invention is to crop safety.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these embodiments.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Content described in embodiment is all weight percentage.
Example of formulations 1:60% nitre benzene bacterium ester Boscalid wetting powder.
Mix entering in blender after said components in proportion coarse crushing, more namely obtain 60% nitre benzene bacterium ester Boscalid wetting powder after air-flow crushing.
Example of formulations 2:20% nitre benzene bacterium ester Boscalid suspending agent.
After above-mentioned each component in proportion coarse crushing, enter in blender and mix, more namely obtain 20% nitre benzene bacterium ester Boscalid suspending agent after sand mill grinding.
