Abstract
The invention discloses a kind of composition pesticide containing pyraflufen-ethyl and pyraclostrobin.It includes active ingredient and auxiliary agent, and wherein active ingredient is made up of pyraflufen-ethyl and pyraclostrobin, and the weight ratio of the two is 1：10~1：20, active ingredient accounts for the 20%~60% of composition pesticide gross weight.The composition pesticide of the present invention has obvious preventive and therapeutic effect to cotton boll blight, and can mitigate the weak saprophytic disease of the other pathogenic bacteria infecting potentials of cotton boll, plays a part of protecting bell volume increase, and dosage is few, facilitate dispenser, alleviates the pollution to environment.
Description
Technical field
The present invention relates to a kind of composition pesticide containing pyraflufen-ethyl and pyraclostrobin, for preventing and treating cotton boll blight, belong to
Agricultural technology field.
Background technology
Cotton boll blight (Phytophthora boehmeriae Sawada) is the important disease in Cotton in China production.Epidemic disease
Disease can fall ill in cotton growth each period, but endanger the most serious with the bell phase.The bell phase susceptible cotton boll that can directly cause harm, be simultaneously
Passage is opened in the invasions of other pathogens, the symptom such as can be caused stiff valve, be rotted, having a strong impact on cotton quality and yield.
Pyraflufen-ethyl (Pyraflufen-ethyl), chemical name：The chloro- 5- of 2- (the chloro- 5- difluoro-methoxies -1- methyl pyrroles of 4-
Azoles -3- bases) -4- fluorophenoxyacetate ethyl esters are a kind of phenyl pyrazoles herbicide after seedling.After the medicament cauline leaf process, it can
It is rapidly absorbed in plant tissue, makes plant downright bad rapidly, or make cauline leaf dehydration withered under sunlight irradiation, with good
Defoliation effect.
Pyraclostrobin (Pyraclostrobin), molecular formula：C19H18ClN3O4, chemical name：Methyl (N)-[[[1-
(4- chlorobenzenes) base of pyrazoles -3)-oxygen] -0- methoxyl groups]-N- methoxymethyl carbamates, methoxy acrylic bactericide.Pyrazoles
Kresoxim-methyl is a kind of mitochondrial respiratory inhibitor, and it suppresses mitochondria and exhaled by preventing electron transmission between thin race pigment b and C1
Suction is acted on, and is prevented energy (ATP) of the mitochondria required for from producing and providing cell eubolism, is ultimately resulted in cell death.Should
Bactericide wide sterilization spectrum, can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete.To spore germination
And the growth of leaf intramatrical mycelium has very strong inhibitory action, with protection and therapeutic activity.Available for wheat, peanut, paddy rice, vegetable
The various crops such as dish, fruit tree, tobacco, tea tree, ornamental plant, lawn, preventing and treating sac fungus, basidiomycetes, Fungi Imperfecti and Oomycete are true
The multiple diseases such as microbial leaf blight, rust, powdery mildew, downy mildew, epidemic disease, anthracnose, shot hole, brown spot, damping-off.
The content of the invention
It is an object of the invention to provide a kind of composition pesticide containing pyraflufen-ethyl and pyraclostrobin.Pyrrole in said composition
Careless ether composition has defoliation effect, can improve cotton plants middle and lower part Growth of Cotton Boll environment, be allowed to be unfavorable for pathogenic bacteria infect and
Growth, while pyraclostrobin composition can effectively prevent and treat the generation of epidemic disease caused by oomycetes.The composition pesticide function admirable, prevents
Sick excellent effect, reduces medicament usage amount, beneficial to environmental protection.
The technical scheme is that：A kind of composition pesticide containing pyraflufen-ethyl and pyraclostrobin, it include effectively into
Divide and auxiliary agent, wherein active ingredient is made up of pyraflufen-ethyl and pyraclostrobin, the weight ratio of the two is 1：10~1：20, effectively into
Divide and account for the 20%~60% of composition pesticide gross weight.
Further, the above-mentioned composition pesticide containing pyraflufen-ethyl and pyraclostrobin can be according to those skilled in the art
Known method, using suitable insecticides adjuvant, is configured to suspending agent, dispersible oil-suspending agent, water dispersible granules, wettable powder
The suitable formulation agriculturally used such as agent.Above-mentioned insecticides adjuvant include solvent, emulsifying agent, wetting agent, disintegrant, stabilizer,
Dispersant, thickener, penetrating agent, pH adjusting agent, defoamer, antifreezing agent, carrier etc. are beneficial to active ingredient and stablized in the formulation
All it is the various composition commonly used in pesticidal preparations or allow to use, specific composition and consumption root with the known substance for playing drug effect
Determined according to recipe requirements by testing.
It is a further object of the invention to provide the composition pesticide containing pyraflufen-ethyl and pyraclostrobin in preventing and treating cotton boll
Application in terms of epidemic disease.
The composition pesticide of the present invention prevents and treats the method for cotton boll blight：In cotton boll early stage, using pyraflufen-ethyl pyrrole
Azoles kresoxim-methyl suspending agent or other preparations, add water and are made into suspension spray administration.
The beneficial effects of the invention are as follows：The present invention has obvious prevention effect to cotton boll blight, and can mitigate cotton boll its
The weak saprophytic disease of its pathogenic bacteria infecting potential is (if the effectively hair of other bell phase diseases such as control boll rot of cotton, rouge and powder disease
It is raw), play a part of protecting bell volume increase.After the present invention is with pyraflufen-ethyl and pyraclostrobin compounding simultaneously, its prevention effect is than independent
It is significantly improved using bactericide pyraclostrobin, and reduces the dosage of agricultural chemicals, reduces cost.And dosage
It is few, facilitate dispenser, alleviate the pollution to environment, application value is big, and economic and social benefit is very notable.
Embodiment
Matching somebody with somebody for composition pesticide of the present invention containing pyraflufen-ethyl and pyraclostrobin can pass through embodiment 1, implement
Example 2 and embodiment 3 are specifically described, but not limited to this.

For checking pyraflufen-ethyl and the prevention effect of pyraclostrobin, the present invention is carried out to pyraflufen-ethyl and pyraclostrobin mixture
Field control effectiveness test, process is as follows：
Test site：Stubble is cotton before Selection experiment cotton field, and fertility is higher, and irrigation condition is good, and weed in cotton field is less, four
All environment are cotton, and herbicide used in cotton field is mixed native to broadcast preceding trefanocide (Trifluralin).
Experimental planting management condition：For studying thing for spring sowing cotton, cotton culture managerial skills are higher, it is ensured that cotton is just
It is frequently grown development.Every mu of planting density is 3500-4000 plants.
Insecticide-applying way：10-15 days before Cotton Boll Rot big generation (about early August) dispenser once, using manually bearing
Shi Linong board sprayer spray pesticides, spray piece bore 0.7mm, pump enough air in, even spraying is in cotton boll surface, middle and lower part blade and ground
Face, every mu of actual used water amount is 60 liters (900 liter/hectare).
Investigation method and number of times：Two row cottons (sum is no less than 40 plants) are fixed per cell, medicine is investigated respectively after administration
Afterwards 7, the rotten bell sum of 14 and 21 days.
Preventive effect is calculated：
Preventive effect (%)=(the rotten bell number of the average individual plant of the rotten bell number-processing of the average individual plant of control)/rotten bell number of the average individual plant of control
×100
Result of the test refers to table 1.
Prevention effect of the composition pesticide of the invention containing pyraflufen-ethyl and pyraclostrobin of table 1 to cotton boll blight
As can be seen from Table 1：Substantially, the preventive effect to cotton boll blight is bright for synergistic effect after pyraflufen-ethyl and pyraclostrobin compounding
The aobvious amount ratio for being better than active ingredient in single dose, compound drug is significantly reduced when being used alone, and total active ingredient is also relative to be reduced,
So as to alleviate carrying capacity of environment, reduce use cost.
