Description

A kind of containing pyraclostrobin with the composition pesticide of epoxiconazole
Technical field
The composition pesticide that the present invention relates to, is that compositions is to Semen Tritici aestivi with pyraclostrobin and epoxiconazole as effective ingredient Head blight pathogen Fusarium graminearum (Fusarium graminearum Schw) and wheat yield have synergistic function, It is applicable to prevent and treat wheat scab and wheat increase yield.
Background technology
Pyraclostrobin (pyraclostrobin), for methoxy acrylic New-type wide-spectrum antibacterial, mitochondrion is exhaled Inhale inhibitor, i.e. by stoping electron transfer at cytochrome in synthesizing.There is protection, treatment, blade infiltration conduction, with Time to crop unsoundness effect and production-increasing function.
Epoxiconazole (epoxiconazole) is absorption triazole bactericidal agent in one, its active component epoxiconazole suppression disease The synthesis of bacterium ergosterol, hinders the formation of pathogenic bacteria cell wall, and epoxiconazole molecule is to a kind of fungal enzyme (14- Dencthylase) there is strength affinity, compared with the antibacterial being currently known, can more effectively suppress pathogenic bacteria fungal pathogens.Epoxiconazole Can improve all fourth matter enzymatic activitys of crop, cause the contraction of fungus haustorium, pathogenic bacteria invades in suppression, and this is that epoxiconazole is in all triazoles Unique characteristic in series products.To the leaf on the crops such as Fructus Musae, Herba Alii fistulosi Bulbus Allii, Herba Apii graveolentis, Kidney bean, melon, Germinatus Phragmitis, Semen arachidis hypogaeae, Radix Betae The diseases such as anthrax on pinta, powdery mildew, rust and Fructus Vitis viniferae, white rot have good preventive effect.
Wheat scab another name wheat head wheat head withered, rotten, red wheat head, be one of the Major Diseases of Semen Tritici aestivi.Wheat scab exists The whole world generally occurs, and is distributed mainly on humidity and semi-humid region, especially weather moisten rainy Temperate Region in China and be injured seriously. All can be injured to heading from seedling, mainly cause that Seedling is withered, brown foot rot, stalk rotten and fringe is rotten, the most seriously fringe of wherein causing harm is rotten.Little Wheat head blight is again one of Major Diseases of Semen Tritici aestivi, is also one of disease the most serious in wheat earing stage " three sick three worms ".Little Wheat head blight generally occurs in the whole world, is distributed mainly on humidity and semi-humid region, especially weather moisten rainy ground, temperate zone District is injured seriously.Circulating a notice of according to relevant department, 2012, Huang-Huai-Hai farming region province wheat scab occurring area was about 24,600,000 Mu, has accounted for the 68.3% of the whole province's wheat planting area, created this pathogenetic history of province's gibberella saubinetii, though through with all strength Production loss more than 20 hundred million jin is retrieved in preventing and treating, but still makes wheat yield cause certain loss, has peasant household to thus result in total crop failure, suffers Heavy losses, wheat scab has become the major hidden danger affecting Quality Wheat high yield, should cause everybody great attention.
Being found by experiment that, Fusarium graminearum is had Synergistic to make with epoxiconazole so that 15:5 ratio is mixed by pyraclostrobin With；The field time on 3 years 4 ground shows, 15% pyraclostrobin 5% epoxiconazole suspension concentrate has collaborative work to wheat products increase With.
Can be the dosage form agriculturally commonly used with excipient by certain technological means pyraclostrobin and epoxiconazole composition Such as granule, suspending agent, micro-capsule suspension, the popularization and application of the present invention that is more convenient for after excipient.
Summary of the invention
It is an object of the invention to provide the synergetic pesticide composition that a kind of effective ingredient is pyraclostrobin and epoxiconazole, Preventing and treating for wheat scab provides one effectively to manage instrument, and increasing for wheat yield provides a kind of effective guarantee.
The present invention is achieved through the following technical solutions:
A kind of containing pyraclostrobin with the composition pesticide of epoxiconazole, including usual auxiliaries, pyraclostrobin and phenylate Methyl cyclic-azole, each weight percentages of components is: pyraclostrobin 15%, epoxiconazole 5%, dispersant 7%～13%, emulsifying agent 8% ～13%, thickening agent 0.1%～3%, antifreezing agent 0.1%～5%, stabilizer 0.1%～5%, deionized water complement to 100%.Concrete production stage is: effective ingredient and other auxiliary agent are mixed, and after high speed shear emulsion dispersion, prepares corresponding weight The suspending agent of amount percentage composition.
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 in reaction bulb, the temperature of solution 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 sodium hydroxide 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 The amendment made, replace or improve, belong to the scope of protection of present invention.
