Description
Technical field
The present invention relates to a kind of composition pesticide for preventing and treating cotton field bollworm and application, belong to agricultural technology field.
Background technology
Cotton (Gossypium hirstum L.) is 5,330,000 hm in the long-term cultivated area in China2Left and right, account for cosmopolitan species
The 15% of area is planted, is the important industrial crops in China and textile industry raw material.But cotton be also insect species survey compared with
More, one of heavier crop of causing harm by insect, causes the cotton underproduction 15%~20% throughout the year.Bollworm (Helicoverpa
Armigera) be cotton primary pest, since the 1990s, bollworm is in China's big generation year after year, annual economic damage
Lose and be up to tens billion of members.In recent years, with the promotion and application of Bt cottons, Amount of Cotton Bollworm, band can be efficiently controlled
Significant economic benefit and social benefit are come.But large area plantation Bt cottons generate influence on the ecosystem in cotton field, main
Show as：(1) some sucking pests in cotton field rise to primary pest；(2) transgene cotton later stage Bt toxin expression quantity
Decline, the insecticidal effect of bollworm is weakened；(3) transgene cotton causes lasting selection pressure also to make insect slow to bollworm
Slowly resistance is produced to it.The resistance monitoring as shown by data of nearly 10 years, the field population of heliothis zea generate resistance in the U.S.,
Simultaneously in China, Australia, India, by indoor resistance screening for many years, obtained several has Gao Shui to Cry1A toxin
The strain of flat resistance.Therefore under current shape, the preventing and treating for how effectively carrying out cotton pest ensures the high yield of cotton and high-quality
An important problem, in terms of existing situation, rationally promote and use new chemical insecticide, while with transgenosis Bt cottons
Fit applications are more effectively preventing strategies.
Piemarker (Abutilon theophrasti Medic.) is Malvaceae annual herb plant, is distributed widely in complete
State various regions, it in farmland, wasteland or roadside, is cotton, corn, the main weeds in beans farmland to be frequently grown, while it is cotton boll again
The main Trap plants of worm.Piemarker have the amount of setting seeds greatly and seed vitality it is high the characteristics of, its often easily formation persistence soil species
Word bank, and seed bank is once it is difficult thoroughly to remove to be formed, when piemarker weeds reach certain density can significantly reduce it is most of
The yield of crops, it is therefore necessary to remove.The use of chemical herbicide significantly reduces harm of the weeds to crop.However,
Due to depending on the herbicide similar with mechanism of action is reused for a long time unduly, cause have drug-fast weeds bion continuous
Occur, reduce the preventive effect of chemical herbicide, add the difficulty of weed control.Cut-off 2014, Serbia,
The U.S. and Zelanian corn and Soybean Field kind are found that the piemarker population of anti-atrazine.
Glyphosate (Glyphosate) is to be developed by Monsanto companies in world agriculture with epoch-making for 1971
The broad-spectrum herbicide of meaning.It is the post-emergence herbicide of a kind of efficient, low toxicity, wide spectrum and the non-selective foliage-spray of Uptake and translocation,
Mainly by suppressing enolpyruvyl shikimene phosphate synthase in plant, so as to suppress shikimene to phenylalanine, junket ammonia
The conversion of acid and tryptophan, the synthesis of protein is interfered causes Plant death.At present, glyphosate turns into and in the world should
With the pesticide species most wide, usage amount is maximum, its year sales value occupies first of agricultural chemicals always.However, find in use, grass
Sweet phosphine is low or in the case that illumination is bad in temperature, and drug effect plays not only slow but also relatively low, and general weeds show in 4-7 talent
Damage symptoms：Chlorosis, jaundice, 15-20 talent show that whole strain is withered and dead.
Emamectin-benzoate (abbreviation emamectin benzoate) be with edaphon Avid kyowamycin tunning Ah
It is parent compound to tie up rhzomorph B1, is derived, a kind of new and effective antibioticses Insecticidal and acaricidal agent of optimum synthesis.It is made
With mechanism by suppress the intranueral aminobutyric acid transmission of pest movements make in insect a few houres rapidly paralysis, food refusal, slowly or
It is motionless and dead in 24~48h.The mode of action is using stomach toxicity as main action of contace poison, to beneficial insect in normal dosage ranges
And natural enemy, people, animal safety, can be with most of combined use of pesticides.But 2004 to 2008 years Pakistan reports local twill night
Moth field population has generated 16-77 times of resistance to emamectin benzoate；Jinning, Yunnan, Spring in Pig House of Shanghai Fengxian are found in the monitoring of 2010
45 times to 437 times have been reached to the resistance level of emamectin benzoate with the beet armyworm population of Luhe；Shantou occurs within 2011
The high anti-population of the emamectin benzoate of diamondback moth.At present, North china bollworm to the resistance of emamectin benzoate also in lasting rising.
The content of the invention
The problem of in order to overcome glyphosate and emamectin benzoate single dose quick-acting, preventive effect and lasting period difference, the invention provides one
The composition pesticide of kind preventing and treating cotton field bollworm and application.The present invention by glyphosate and emamectin benzoate single dose respectively with organosilicon auxiliary agent
After compounding, its quick-acting, preventive effect and lasting period are improved.Glyphosate, emamectin benzoate and organosilicon auxiliary agent are carried out ternary by the present invention

All it is to be commonly used in pesticidal preparations or allow the various composition used, specific composition and dosage true by testing according to recipe requirements
It is fixed.
Above-mentioned composition pesticide can directly buy commercially available glyphosate, emamectin benzoate and organosilicon auxiliary agent system when in use
The single dose of agent (such as 41% glyphosate isopropyl amine salt AS, 1% emamectin benzoate EC) mixes by proportioning after diluting respectively and sprayed, and also may be used
So that glyphosate, emamectin benzoate and organosilicon auxiliary agent pesticide original medicine addition auxiliary agent are configured into pesticidal preparations (such as aqua, aqueous emulsion)
After store, be directly watered during use and spray.
It is a further object of the invention to provide the composition pesticide containing emamectin benzoate and organosilicon auxiliary agent in preventing and treating cotton boll
Application in terms of worm, there is provided the composition pesticide containing glyphosate, emamectin benzoate and organosilicon auxiliary agent is while bollworm is prevented and treated
And can prevents and kill off the application in terms of its host plant piemarker.
The application method of present invention preventing and treating cotton field bollworm is as follows：
Method 1：Preventing and treating before cotton planting
Before cotton planting, the region for first having piemarker to field sprays, and eliminates host plant, using sweet containing grass
The composition pesticide of phosphine, emamectin benzoate and organosilicon auxiliary agent, cauline leaf spray-on process are sprayed to piemarker, and spraying is thoughtful uniform；
Prevented and treated using the above method, the bollworm on piemarker and piemarker can be prevented and kill off simultaneously, prevented and treated from root
Piemarker propagates bollworm, has the function that anti-, cost-saving synergistic more than a spray.
After the preventing and treating before cotton planting, piemarker can be thoroughly eliminated, bollworm occurs quantity and declined.If in 2-3
It is still more for bollworm generation phase bollworm, the composition pesticide containing emamectin benzoate and organosilicon auxiliary agent can be used, to cotton
Plant carries out cauline leaf and sprayed 1~2 time, eliminates bollworm.
Method 2：The preventing and treating of phase occurs for bollworm for 2-3
For bollworm phase, and the peak period that the weeds such as cotton field piemarker occur occur for 2-3, using containing glyphosate, emamectin benzoate
With the composition pesticide of organosilicon auxiliary agent, cauline leaf spray-on process is sprayed to piemarker, prevents and kill off piemarker；Simultaneously using containing emamectin benzoate with
The composition pesticide of organosilicon auxiliary agent, to cotton plants carry out cauline leaf spraying, prevent and treat bollworm, if later stage bollworm still compared with
It is more, it can supplement and spray 1 time.
Preferably, when being sprayed to piemarker, if piemarker grass age is smaller (2-5 leaf phases), 41% glyphosate AS 400-500 are recommended
Times, 1% emamectin benzoate EC 1000 again with 1000 times of liquid of organosilicon auxiliary agent；If piemarker grass age is larger (6-7 leaf phases), recommend 41% grass
Sweet 300 times of phosphine AS, 1% emamectin benzoate EC 1000 again with 1000 times of liquid of organosilicon auxiliary agent.
Preferably, cotton plants are sprayed, compounded again with 1000 times of liquid of organosilicon auxiliary agent using 1% emamectin benzoate EC 1000
Afterwards, cauline leaf spraying is carried out to cotton plants.
Further, if the cotton of field planting is transgenosis resistance glyphosate cotton, 41% glyphosate AS 300- can be used
500 times, 1% emamectin benzoate EC 1000 with 1000 times of liquid of organosilicon auxiliary agent, stem is carried out to cotton plants and piemarker after ternary built again
Leaf spray-on process, liter/hectare of water consumption 300~450, spraying are thoughtful uniform.It can be prevented and kill off in piemarker and cotton, piemarker simultaneously
Bollworm, preventing and treating bollworm ratio is more thoroughly.
Piemarker is the main weeds in cotton field, and when piemarker density is long up to 5~8 plants/m rows, weed competition causes cotton to give birth to
Phase postpones, and cotton bell weight, single bell seed number and ginning outturn decline, it is therefore necessary to the piemarker in removes cotton field.Piemarker is bollworm again
Main Trap plants, if prevent and kill off the host plant piemarker of bollworm, after piemarker is withered, the bollworm on piemarker is still
So it can further select to be transferred on cotton plants to endanger.Glyphosate, emamectin benzoate and organosilicon auxiliary agent are carried out three by the present invention
After member compounding, the double effectses prevented and kill off cotton field piemarker and prevent and treat bollworm are played.
The present invention is found through experiments that：(1) after glyphosate and the outstanding effect profit of organosilicon auxiliary agent compound, accelerate glyphosate and prevent and kill off
Quick-acting, preventive effect and the lasting period of piemarker, wherein after 300,400,500 times of liquid and 1000 times of organosilicon auxiliary agent compounding use,
The preventive effect of 5 days has reached more than 85% after medicine, and the preventive effect of 28 days has reached 100% after medicine, far above glyphosate conventional amount used
The single dose preventive effect of (200 times)；(2) after the outstanding effect profit compounding of emamectin benzoate and organosilicon auxiliary agent, improve preventing and treating bollworm quick-acting,
Preventive effect and lasting period, and delayed pest resistance to insecticide, 48h preventive effects improve 20% after its Chinese medicine；(3) glyphosate, emamectin benzoate and have
Machine silicon additive ternary recompounded composite to the preventive effect of piemarker and bollworm respectively with glyphosate and organosilicon auxiliary agent, emamectin benzoate
It is on close level with the effect of organosilicon auxiliary agent compounding；Ternary recompounded composite plays pair prevented and kill off cotton field piemarker and prevent and treat bollworm

5 brief summaries
Preventive effect of the Ternary composition of table 4 to 2-3 leaf phase piemarkers
Preventive effect of the Ternary composition of table 5 to 4-5 leaf phase piemarkers
Preventive effect of the Ternary composition of table 6 to 6-7 leaf phase piemarkers
Prevention effect of the Ternary composition of table 7 to bollworm
41% glyphosate AS sprays different bearing again according to 300,200 (conventional amount useds) it can be seen from table 4, table 5, table 6
The piemarker of phase shows as, and according to the use of 200 times of conventional amount used, has preferable preventive effect to the piemarker of 2-3 leaf phases, to medicine after 21 days,
Preventive effect reaches 95.0%, but quick-acting is poor；The preventive effect of 4-5 leaf phases, 6-7 leaf phases are gradually dropped with the increase of breeding time
It is low.It is poor to the piemarker preventive effect of 2-3 leaf phases, 4-5 leaf phases, 6-7 leaf phases according to 300 times of uses.Also, later stage discovery has portion
Divide withered plant and can to grow tender shoots from base portion, therefore be decreased obviously to the strain preventive effect of 28 days after medicine.
However, after glyphosate and organic silicon compound, respectively according to low dosage 300,400,500,600 times of liquid and 1000 times
After organosilicon auxiliary agent compounding use, in the case where reducing the dosage of glyphosate, the herbicidal effect of glyphosate can be significantly improved, and
Quick-acting is significantly improved, processing of the damage symptoms than being not added with organosilicon auxiliary agent, which occur, in weeds will shift to an earlier date 2-3 days, such as in piemarker
2-3,4-5 leaf phase, 5 days its preventive effects are more than 80.0% after medicine for above-mentioned 4 kinds of complex compositions, and 200 times of conventional amount used
The preventive effect used only respectively reaches 31.7%, 58.9%.Meanwhile after glyphosate and organic silicon compound, its lasting period is also extended,
After to medicine 28 days its preventive effects still be up to more than 97.0% (except 600 times+auxiliary agent of glyphosate, 1000 times of compositions), do not find from
Withered plant base portion grows new tender shoots, and piemarker is thoroughly eliminated.Above-mentioned 4 kinds of complex compositions are with 300+
1000th, 400+1000,500+1000 compounding use effect are best, especially 300+1000,400+1000, to 3 kinds of different bearings
The preventive effect of the piemarker of phase is significantly better than the preventive effect of alone 200 times of liquid of glyphosate.
As can be seen from Table 7,1% emamectin benzoate EC uses according to 1000 times of liquid, prevention effects of the 48h to bollworm after medicine
Reach 73.2%, and with after additive compound, significantly improving its prevention effect to bollworm, to medicine after 48h preventive effects be up to
93.3%.
Glyphosate, emamectin benzoate and organosilicon auxiliary agent ternary recompounded composite are to piemarker and cotton boll it can be seen from table 4- tables 7
Effect of the preventive effect of worm respectively with glyphosate and organosilicon auxiliary agent, emamectin benzoate and organosilicon auxiliary agent compounding is on close level.Can
See, while bollworm is prevented and treated, and can is enough significantly effective for glyphosate, emamectin benzoate and organosilicon auxiliary agent ternary recompounded composite
The host plant piemarker of bollworm is removed, while dosage is reduced, serves the anti-effect of a spray two.
In summary, the prevention and controls of recommendation are as follows：
Method 1：Preventing and treating before cotton planting
Before cotton planting, the region for first having piemarker to field sprays, and host plant is eliminated, if piemarker grass age
Smaller (2-5 leaf phases), recommend 41% glyphosate AS 400-500 times, 1% emamectin benzoate EC 1000 again with 1000 times of organosilicon auxiliary agent
Liquid；If piemarker grass age is larger (6-7 leaf phases), recommend 300 times of 41% glyphosate AS, 1000 times of 1% emamectin benzoate EC and organosilicon
1000 times of liquid of auxiliary agent, use cauline leaf spray-on process after ternary built, liter/hectare of water consumption 300~450, and spraying is thoughtful uniform.
After the preventing and treating before cotton planting, piemarker can be thoroughly eliminated, bollworm incidence declines.If in 2-3 generations
Bollworm generation phase bollworm is still more, after recommending 1% emamectin benzoate EC 1000 to be compounded again with 1000 times of liquid of organosilicon auxiliary agent,
Cauline leaf is carried out to cotton plants to spray 1 time, prevents and kill off bollworm.
Method 2：For bollworm phase preventing and treating occurs for 2-3
For bollworm phase, and the peak period that the weeds such as cotton field piemarker occur occur for 2-3, if piemarker grass age smaller (2-5 leaves
Phase), recommend 41% glyphosate AS 400-500 times, 1% emamectin benzoate EC 1000 again with 1000 times of liquid of organosilicon auxiliary agent；If piemarker
Careless age is larger (6-7 leaf phases), recommend 300 times of 41% glyphosate AS, 1% emamectin benzoate EC 1000 again with 1000 times of organosilicon auxiliary agent
Liquid, piemarker cauline leaf is sprayed using cauline leaf spray-on process after ternary built, liter/hectare of water consumption 300~450, meanwhile, recommend
1% emamectin benzoate EC 1000 is again with after 1000 times of liquid compoundings of organosilicon auxiliary agent, carrying out cauline leaf spraying to cotton plants, preventing and treating cotton boll
Worm.
If the cotton of field planting is transgenosis resistance glyphosate cotton, 41% glyphosate AS 300-500 times, 1% first can be recommended
Salt EC 1000 is tieed up again with 1000 times of liquid of organosilicon auxiliary agent, and cauline leaf spray-on process is carried out to cotton plants and piemarker after ternary built, used
Liter/hectare of water 300~450, spraying are thoughtful uniform.
