Description
Technical field
The invention belongs to pesticide combination applied technical field, being specifically related to a kind of composition pesticide containing benzo alkene fluorine bacterium azoles and tetraconazole, for preventing and treating powdery mildew of cucumber.
Background technology
Powdery mildew of cucumber is commonly called as " white defect ", is one of Common Diseases in cucumber cultivation.Be injured the heaviest with blade, be secondly petiole and stem, generally do not endanger fruit.Their early stage, face of blade or the back side produce the rotund little amyloid plaque of white, being expanded into unconspicuous large stretch of white powder district, edge gradually, being covered with blade face, as having spread layer white powder.Erase white powder, visible blade face chlorisis, withered and yellowly to become fragile.When falling ill serious, blade face is covered with white powder, becomes canescence, until whole blade is withered.After powdery mildew infects petiole and tender stem, similar on blade of symptom, only scab is less, and powder is also few.Blade starts produce yellow point, then expand and develop into circle or oval scab, the mould layer of the raw adularescent powdery in surface.Ordinary circumstance bottom blade is more than upper blade, and vacuum side of blade is more than front.Mildew is disperseed separately in early days, after be unified into a large mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, causes early ageing, output incurs loss.Due in recent years, powdery mildew produces certain pesticide resistance, and all can fall ill throughout the year, brings certain difficulty to control.The general time underproduction is about 10%, and the popular time underproduction is at about 20%-40%.
Benzo alkene fluorine bacterium azoles (benzovindiflupyr), pyrazole amide series bactericidal agent, its mechanism of action is succinate dehydrogenase inhibitors (SDHI).
Tetraconazole (tetraconazole) triazole bactericidal agent, its mechanism of action is the precursor of sterol in Antifungi---the demethylation effect on lanosterol or 2,4-methylene dihydro wool steroid 14.
The present invention conducts in-depth research tetraconazole, benzo alkene fluorine bacterium azoles and combination thereof, on the basis of a large amount of tests, find that tetraconazole and benzo alkene fluorine bacterium azoles combine powdery mildew of cucumber performance synergistic effect within the scope of certain proportion, can the excipient formulations of pesticide by technology.After further study, the present invention is completed.
Summary of the invention
The object of the present invention is to provide a kind of efficient, low toxicity, low cost, quick-acting are good, the lasting period is long, to crop safety, environment amenable composition pesticide.
The present inventor, by a large amount of indoor bioassay test and field medicine effect test, finds benzo alkene fluorine bacterium azoles and tetraconazole in certain proportion after mixture, has significant synergistic effect to powdery mildew of cucumber.
On the basis of above-mentioned discovery, after further study, define technical scheme of the present invention, that is: a kind of composition pesticide containing benzo alkene fluorine bacterium azoles and tetraconazole, it is characterized in that: comprise benzo alkene fluorine bacterium azoles and tetraconazole and insecticides adjuvant, the ratio of weight and number of benzo alkene fluorine bacterium azoles and tetraconazole is 1:20 ~ 20:1, and benzo alkene fluorine bacterium azoles and the percentage by weight of tetraconazole weight summation in composition pesticide are 5% ~ 80%.
Composition pesticide of the present invention according to well known to a person skilled in the art method, can be processed into the application forms of the applicable agricultural uses such as suspending agent, water dispersible granules, wetting powder.
Composition pesticide of the present invention is also containing the auxiliary element of preparation needed for pesticidal preparations, comprise one or more mixing in emulsifier, wetting agent, stabilizing agent, dispersant, thickener, defoamer, antifreezing agent, disintegrant, binding agent, filler, filler, medium etc., be known substance, various auxiliary agents conventional in pesticidal preparations, can change to some extent according to different situations, be not particularly limited.
Composition pesticide described in the invention, can finished product preparation form provide, namely in composition, each material mixes, and the composition of composition also can provide by unit dose form, directly mixes in bucket or tank, be then diluted to desired concn before using.
Composition pesticide described in the invention, for preventing and treating powdery mildew of cucumber.
Composition pesticide described in the invention, usually adopts the method for spraying to use, also can adopt other operation technique agriculturally applied as required.
Composition pesticide of the present invention has following beneficial effect:
1, combine in certain ratio range powdery mildew of cucumber performance synergistic function, improve result of use;
2, two kinds of active ingredient mechanisms of action are not identical, effectively administer powdery mildew of cucumber to active ingredient resistance product, extend the service life of active ingredient;
3, cost and the auxiliary agent consumption such as single active ingredient production, packaging, transport is reduced.
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 examples.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.
Chemical control information system of crop pest distribution in China is common method, is combined by dissimilar pesticide active ingredient, usually shows three kinds of type of action, i.e. antagonism, summation action and synergistic effect.The present inventor is on the basis of a large amount of Toxicity Determination, pesticidal preparations Recipe and field control effectiveness test, find that benzo alkene fluorine bacterium azoles and tetraconazole are combined within the scope of certain proportion thorn dish spore bacterium synergistic function, be prepared into suspending agent by pesticidal preparations Recipe, be applied to the powdery mildew of cucumber of preventing and treating the initiation of thorn dish spore bacterium and significantly improve control efficiency.
