The present invention is the development of pyraclostrobin, prothioconazoles suspending agent and suspension seed-coating agent, for the composition pesticide of a kind of pyraclostrobin-containing and prothioconazoles, belong to chemical prevention field, it is made of effective component pyraclostrobin and prothioconazoles and its auxiliary agent, has good synergistic effect, control efficiency to wheat diseases, peanut disease.The synergic ratio of the composition pesticide is 11:1 ~ 1:11.The invention patent has synergistic effect significant, and preventive effect is good, and dosage is low, and to environment and target organisms safety, the features such as controlling a medicine, this composition simultaneous can control other diseases, have good effect to drug resistance of the Common Diseases to medicament more.
Description
Technical field
The invention belongs to pesticide producing application fields, and in particular to a kind of prothioconazoles and 12% aqueous suspension of pyraclostrobin
Agent prescription development and application.
Background technique
Aqueous suspension agent is because of its environment-friendly high-efficiency, and easy to use, production cost is low, and environmental pollution is small increasingly by user's
It welcomes, is the main flow direction of green bioagrochemicals development.Aqueous suspension agent in process, the difference of chemical content, auxiliary agent etc.
Very big difference can be caused to the suspension system of aqueous suspension agent.
Pyraclostrobin belongs to methoxy acrylic bactericide, high-efficiency broad spectrum;Prothioconazoles belong to triazole type sterilization
Agent has good absorbability and bioactivity.Composite reagent is to expand medicament disinfecting spectrum, and delay medicament drug resistance has efficacious prescriptions
One of formula.Both pyraclostrobin and prothioconazoles belong to the fungicide of different role mechanism, can play after mixture very well mutually
Mend synergistic effect.
There is the problems such as crystallization, aggregation, sedimentation in present aqueous suspension agent, good adjuvant system can be good at making up aqueous suspension
These defects of agent, play the role of good.
Summary of the invention
The object of the present invention is to provide the production method of 12% pyraclostrobin prothioconazoles aqueous suspension agent and preventing and treating
Application in wheat scab and rust.The antimicrobial combination preparation stabilization, preventive effect is good, can be very good to realize that a spray is mostly anti-.
The invention provides the following technical scheme:
The 12% aqueous suspension agent development of prothioconazoles and pyraclostrobin, steps are as follows (medicament ratio is without being limited thereto):
Prothioconazoles, pyraclostrobin each 6%, the components such as blended emulsifier, thickener, antifreezing agent are taken, water supplies 100%, is sanded
Machine is sanded to 3-5 microns of partial size, and the substances such as defoaming agent are added, and is uniformly mixed, that is, suspending agent is made.
Wherein emulsifier is preferably sodium lignin sulfonate, NNO, polyethylene glycol, castor oil and ethylene oxide condensate, loses
One of water sorbitan fatty acid rouge, JFC etc. or a variety of compositions;
Wherein thickener is preferably aluminium-magnesium silicate, xanthan gum ,-cyclodextrin, sodium carboxymethylcellulose, polyvinyl alcohol, bleeding agent
One of JFC or a variety of compositions.
Antifreezing agent is selected from one of ethylene glycol, glycerine, glycerol, urea or numerous compositions.
Milling time is 0.3-1 hours.
Aqueous suspension agent performance produced by the present invention is stablized, and spray particle diameter is uniform, has the advantages that higher suspension rate.System of the present invention
The aqueous suspension agent milling time obtained is short, and energy-saving consumption-reducing also complies with the theory of formulations of pesticide Green Development using water as carrier.
12% pyraclostrobin prothioconazoles aqueous suspension agent produced by the present invention can be applied not only to wheat scab,
The prevention and treatment of rust, powdery mildew can also add pigment, film forming agent etc. for crops such as peanut, soybean, corn, wheat, rice
Coating.
12% pyraclostrobin prothioconazoles aqueous suspension agent disclosed in this invention is different from the patent having disclosed
Suspending agent, compared to published suspending agent, in terms of aqueous suspension agent storage stability disclosed by the invention, field use aspect more
Tool advantage not only facilitates spraying use, but also coating is facilitated to make the present invention has the advantages that the total content of both (1) is limited to 12%
With;(2) can be mostly anti-with a spray, there is good preventive effect to the crops multiple diseases such as wheat, be easy to use, reduces cost;(3) it develops
Suspending agent physical behavior it is more stable, by spraying use when mist droplet particle size it is more uniform.
