Description
Technical field
The present invention relates to a kind of composition pesticide containing pyraflufen-ethyl and trifloxystrobin, for preventing and treating cotton boll blight, belong to agricultural
Technical 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.
Trifloxystrobin (Trifloxystrobin), molecular formula C20H19F3N2O4, chemical name：Methyl (E)-methoxyl group imines
Base-{ (E)-α-[1- (the fluoro- m- tolyls of α, α-three)-ethyleneimino epoxide]-o-tolyl } ethyl acetate.Trifloxystrobin belongs to oxime
Bacterium esters wide-spectrum bactericide, is the class successfully developed as bactericide lead compound from natural products Strobilurins
New fungicides, with efficient, wide spectrum, protection, treat, root out, permeate, systemic activity, resistance of rainwater washing against, lasting period it is long
Etc. characteristic.Trifloxystrobin produces resistance to Isosorbide-5-Nitrae-demethylation enzyme inhibitor, benzamides, dicarboxyl amine and benzimidazole
Bacterial strain effectively, bactericide no interactions resistance is had with current.To nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete
And Fungi Imperfecti) disease such as powdery mildew, leaf spot, rust, downy mildew, damping-off, apple apple scab, sclerotinia sclerotiorum etc. have
There is good activity.Because its in soil, water it is capable of being fast degraded, it is therefore environmentally safe.
The content of the invention
It is an object of the invention to provide a kind of composition pesticide containing pyraflufen-ethyl and trifloxystrobin.Pyraflufen-ethyl in said composition
Composition has defoliation effect, can improve cotton plants middle and lower part Growth of Cotton Boll environment, is allowed to be unfavorable for pathogenic bacteria to infect and grow,
Trifloxystrobin composition can effectively prevent and treat the generation of epidemic disease caused by oomycetes simultaneously.The composite behaviour is excellent, and protection effect is excellent, reduces
Medicament usage amount, beneficial to environmental protection.
The technical scheme is that：A kind of composition pesticide containing pyraflufen-ethyl and trifloxystrobin, it include active ingredient and
Auxiliary agent, wherein active ingredient are made up of pyraflufen-ethyl and trifloxystrobin, and the two weight ratio is 1：10~1：20, active ingredient accounts for agricultural chemicals group
The 30%~70% of gross weight in compound.
Further, the above-mentioned composition pesticide containing pyraflufen-ethyl and trifloxystrobin can according to well known to a person skilled in the art
Method, using suitable insecticides adjuvant, is configured to suspending agent, dispersible oil-suspending agent, water dispersible granules, wettable powder etc. and fits
Close the formulation agriculturally used.The insecticides adjuvant used in composition pesticide of the present invention includes solvent, emulsifying agent, wetting agent, collapsed
Solution agent, stabilizer, dispersant, thickener, penetrating agent, pH adjusting agent, defoamer, antifreezing agent, carrier etc. are beneficial to active ingredient
Stablize and play the known substance of drug effect in the formulation, be all the various composition commonly used in pesticidal preparations or allow to use, specifically
Composition and consumption are determined according to recipe requirements by testing.
Cotton boll blight is being prevented and treated it is a further object of the invention to provide the composition pesticide containing pyraflufen-ethyl and trifloxystrobin
The application of aspect.
The composition pesticide of the present invention prevents and treats the method for cotton boll blight：In cotton boll early stage, using pyraflufen-ethyl oxime
Bacterium ester 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 trifloxystrobin compounding simultaneously, its prevention effect is than being used alone
Bactericide trifloxystrobin is significantly improved, and reduces the dosage of agricultural chemicals, reduces cost.It is convenient and dosage is few
Dispenser, alleviates the pollution to environment, and 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 trifloxystrobin can pass through embodiment 1, the and of embodiment 2
Embodiment 3 is specifically described, but not limited to this.

Comparative example 2：
40% trifloxystrobin suspending agent.
For checking pyraflufen-ethyl and the prevention effect of trifloxystrobin, the present invention has carried out field medicine to pyraflufen-ethyl and trifloxystrobin mixture
The process for imitating experiment 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 trifloxystrobin of table 1 to cotton boll blight
As can be seen from Table 1：Substantially, the preventive effect to cotton boll blight is substantially good for synergistic effect after pyraflufen-ethyl and trifloxystrobin compounding
Significantly reduced when the amount ratio of active ingredient is used alone in single dose, compound drug, total active ingredient is also relative to be reduced, so that
Alleviate carrying capacity of environment, reduce use cost.
