Description

Composition pesticide containing Difenoconazole and pyraclostrobin
Technical field
The composition pesticide that the present invention relates to, is with pyraclostrobin and Difenoconazole as active ingredient, composition pair Watermelon anthrax pathogen colletotrichum gloeosporioides Penz watermelon specialized form and the yield of watermelon have synergistic function, it is adaptable to preventing and treating watermelon Anthracnose and increasing yield of water melons.
Background technology
Pyraclostrobin (pyraclostrobin), is methoxy acrylic New-type wide-spectrum bactericide, and mitochondria is exhaled Inhale inhibitor, i.e. by stoping electro transfer in cytochromes synthesis.There is protection, treatment, blade infiltration conduction, with When to crop unsoundness effect and production-increasing function.
Difenoconazole (difenoconazole) is that in triazole bactericidal agent, security is higher, and fungicidal spectrum is wide, right Ascomycetes, Basidiomycetes and include Alternaria, Ascochyta, Cercospora, Colletotrichum, ball Cuo Pseudomonas, Phoma, Ramularia, Septoria, Venturia partly know disease at interior, and Erysiphaceae, Uredinales and some Seedborne pathogen have persistently Protection and therapeutic action, be widely used in the crop such as fruit tree, vegetables, effectively preventing and treating scab, anthrachose of grape, white rot, spot Defoliation, powdery mildew, brown spot, rust, stripe rust, head blight etc..
Watermelon anthrax all has generation throughout the country, especially occurs serious with moist area of heavy rainfull, south, causes dead seedling, rotten Melon and the underproduction.In addition to watermelon, the also various vegetables such as harm cucumber, eggplant, tomato, Kidney bean.
Being found by experiment that, pyraclostrobin is mixed special to colletotrichum gloeosporioides Penz watermelon with 10:20 ratio with Difenoconazole Change type has synergistic function；The field time on 3 years 4 ground shows, 10% pyraclostrobin 20% difenoconazole suspending agent pair Watermelon products increase has synergy.
Content of the invention
It is an object of the invention to provide the Synergistic fertilizer group that a kind of active ingredient is pyraclostrobin and Difenoconazole Compound, the preventing and treating for watermelon anthrax provides a kind of effectively management instrument, and increasing for the yield of watermelon provides a kind of effective guarantee.
The present invention is achieved through the following technical solutions:
A kind of composition pesticide containing Difenoconazole and pyraclostrobin, including usual auxiliaries, pyraclostrobin and Difenoconazole, each weight percentages of components is: pyraclostrobin the 10%th, Difenoconazole the 20%th, dispersant 7%～13%, Emulsifying agent 8%～13%, thickener 0.1%～3%, antifreezing agent 0.1%～5%, stabilizer 0.1%～5%, deionized water are mended Foot is to 100%.Concrete production stage is: mix active ingredient and other auxiliary agents, after high speed shear emulsion dispersion, prepares phase Answer the suspending agent of weight percentage.
Described dispersant is that (BBM-3 hereinafter relates to this ternary to a kind of combed carboxylate terpolymer dispersing agent All replacing with BBM-3 of copolymer dispersant), this copolymer comes from Chinese Patent Application No. 201310521909.7, is a kind of With acrylic homolog, mono polyethylene glycol maleate, acrylate as monomer, in aqueous phase system with free radical altogether Poly-method synthesis, concrete, it is made up of the monomer of following weight ratio: acrylate 10～50 parts, acrylic homolog 10 ～80 parts, mono polyethylene glycol maleate 10～50 parts, processing step is as follows: by 1000 parts of distilled waters, 10 parts of surfaces Activating agent joins in four mouthfuls of reaction flasks, heats while stirring；When the temperature of solution in reaction bulb rises to 60 DEG C, add 200 parts of acrylate, 500 parts of acrylic homolog, 100 parts of mono polyethylene glycol maleates and 30 parts of initiator solutions Add in 1 hour, then 60 DEG C of insulation reaction 2 hours；Insulation reaction is down to room temperature after terminating while stirring, molten with NaOH Carboxylic acid in liquid and in system, dosis neutralisata is the 50% of carboxyl molal quantity, prepares destination scatter agent solution.
Detailed description of the invention
In order to be more fully understood that the essence of the present invention, below in conjunction with embodiment, present disclosure is described further, But can not be considered as limitation of the present invention, the following stated is only used for explaining the present invention, for without departing from present invention spirit and principle Modification, replacement or the improvement made, belongs to the scope of protection of present invention.
