Description
One, invention and created name
Longicorn is clearly a thiophene worm quinoline suspending agent, is that the former medicine of thiophene worm quinoline is with wetting agent/dispersant, thickener, stabilizing agent, antifoaming agent, antifreezing agent, thixotropic agent, antifoaming agent and deionized water high shear, again through obtaining product behind the sand mill sand milling.Longicorn is clearly series of products, and the content of former medicine thiophene worm quinoline can be 5%, 20% or 48%, and the innovation of present technique is thiophene worm quinoline is processed into stable suspending agent, and is used for the control of pine nematode.
Two, background technology
Pine nematode is the dangerous forest disease and pest of in the world tool, and host plant infects pine wood nematode can be dead after 40 days after being ill.Therefore, be called as pine tree " cancer ".Again because of its spread speed is exceedingly fast, and in case infection is difficult to control, so claim pine tree " AIDS " again.Its harm that causes is destructive.The control of this disease has become global problem, causes the great attention of countries in the world.Many countries classify this disease as the import and export quarantine object.
China's area of woods reaches 1.75 hundred million hectares.According to forest department's statistics, the whole nation has more than 500,000,000 mu of pine forest to meet with the erosion of pine wood nematode, and the direct economic loss that causes every year reaches 2,500,000,000 yuan, and indirect loss reaches 25,000,000,000 yuan.Zhejiang Province is that the most serious province takes place national pine nematode, area takes place the half the of the gross area takes place the whole nation nearly.By in October, 2002; The lesion has related to the whole province 18 counties (city, district); 8.0 hundred million yuan of direct economic losses have been invaded holy place of Buddhism Mount Putuo and well-known scenic area, the West Lake at present, and national scenic spot such as Thousand-Island Lake, the Tian Mu Shan Mountain, Xi Kou, Wild Goose and Reed Marsh Mountains are constituted a serious threat.In pine nematode emphasis generating region, the part forest land deteriorates to the deserted mountain because of pine nematode endangers continuously.
At present, this disease is not effectively controlled, and with regard to the whole nation, no matter this disease is that local area or entire scope all are the gesture that expansion spreads, and is still constantly spreading to whole middle and southern large tracts of land pine forest new epidemic place.Last year, epidemic situation fed through to the ground such as Xingzi County of underfooting, Mount Lushan, Jiangxi; Situation is very severe; Is world's natural culture legacy of main view to China with pinaceae plant, constitutes a serious threat like the ecological safety in famous mountains, the world such as Mount Huang, Zhangjiajie, Mount Lushan, has caused the great attention of country.
Pine tree is industrial or agricultural with material, the masses main source with material.Because the frequent generation of forest disease and pest, the pine tree that catches an illness can not be used, and the influence foreign exchange earning is seriously restricting the performance of forest resources function.It is thus clear that pine nematode has not only destroyed the forest resources and ecotope, and hindered the sound development of national economy with society.
The control of pine wood nematode is a global problem.Because pine wood nematode survives in the trunk; Medicine is difficult to directly act on polypide; The method of generally acknowledging in the world at present is the vector insect to pine wood nematode---Monochamus alternatus Hope carries out prevention and control, and (Monochamus alternatus Hope can be propagated pine wood nematode very effectively; Average 15000 of every longicorn portability pine wood nematode), to cut off the route of transmission of pine wood nematode.But worldwide also do not produce a kind of economy, effective ideal product of environmental protection again so far.China mainly is to adopt chemical agent to the method for preventing and treating of pine wood nematode, sprays chemical pesticide because of large tracts of land and causes the enhancing of disease worm pesticide resistance, contaminated environment, destruction ecology, killed natural enemies to form vicious circle.Human to the consideration of sustainable development and to the care of its own existence environment, much more more and more in insect is administered, require to take with the biological control is the integrated management principle of leading.World developed country comprises that some developing countries are all in the development that steps up forestry PCO Study on Technology and biopesticide.
Thiophene worm quinoline is novel chloro nicotine compound, acts on the nicotinic acid acetylcholinergic receptor of insect, have stronger tag, stomach toxicity and systemic action, be one of efficient medicament of control pierce-suck type and pests with chewing mouthparts.The former medicine of thiophene worm quinoline was developed cooperatively by Japanese Bayer farmingization company and Bayer farmingization company the nineties in last century.Japan once was the most serious country of pine nematode harm, and in recent years, Japan promotes the use of thiophene worm quinoline control Monochamus alternatus Hope, and control efficiency is very good, makes pine nematode obtain effective control in Japan, the withered loss rate of pine tree dropped to ten thousand/.
Gloomy anti-master station of country will have promoted mainly thiophene worm quinoline preparation aspect the control pine nematode since the end of the year 2008, mainly there are following characteristics in former medicine of thiophene worm quinoline and preparation:
(1) desinsection is quick-acting, and the power of knocking down is strong: thiophene worm quinoline desinsection is quick-acting, and the power of knocking down is strong.Thiophene worm quinoline acts on the neural caudacoria that engages of insect, through combine the neural normal conduction of interference insect with the nicotinic acid acetylcholinergic receptor; Cause the obstruction of neural channel, cause a large amount of accumulation of acetylcholine, thereby make the insect exaltation; The whole body spasm, paralysis and dead.The Monochamus alternatus Hope and other the multiple longicorns that are difficult to prevent and treat for general insecticide; Has killing effect fast; Can make coleopteron such as longicorn in 10min, lose ability to act, can effectively cut off the main communication media of pine wood nematode, suppress the generation of pine nematode.Test shows that thiophene worm quinoline is fairly obvious to the effect of tagging of Monochamus alternatus Hope, and 2 hours longicorns begin mortality after the dispenser, and the control efficiency after 24 hours can reach more than 90%.
(2) insecticidal spectrum is wide
Thiophene worm quinoline insecticidal spectrum is very wide, and a lot of insects of coleoptera, Lepidoptera, Semiptera, Homoptera and orthoptera are all had good control efficiency, can be widely used in multiple forestry and agricultural insect management.In the control Monochamus alternatus Hope; To simultaneous other longicorns, Chinese chestnut beta pruning resemble, hylobitelus xiaoi zhang, flatheaded borer, colorado potato beetle, black cutworm, white line dart moth of turnip, peanut grub, chafer, bright strong different stinkbug, poplar caterpillar, fall webworm, Yang Xiaozhou moth, Closteraanastomosis L., tent caterpillar, dendrolimus punctatus, Parocneria orienta Chao, oriental moth,, bag moth, two spotted spider mite, bamboo locust, grassland caterpillar, grassland grasshopper, aphid, tea geometrid, tea lesser leafhopper etc.; Also can play preventive and therapeutic effect simultaneously; Need not dispenser separately; Can receive " medicine is prevented many worms " double effect of controlling, reduce and repeated to prevent and treat cost.
(3) no cross resistance
Organic phosphates, carbamates act on the acetylcholinesterase of insect, and pyrethroid acts on neural axon, influence the sodium-ion channel in the insect nerve cell.Because action site is different with the mechanism of action, thiophene worm quinoline and common insecticides do not have cross resistance, thereby can be used for resistance management, are widely used in those have produced the forestry pest of resistance to organic phosphates, carbamates, cinerins control.
(4) half life period weak point, safety and environmental protection
Thiophene worm quinoline low toxicity, environmental protection, very little to external environment influence, have the following advantages:
1. to people, animal safety.Thiophene worm quinoline has very high insecticidal activity to Monochamus alternatus Hope, but its toxicity is extremely low, and people and animals are had very high safety, and medicament is destitute of smell or excitant, to dispenser operating personnel and applying area resident safety.
2. environmentally safe.Because the steam of its active ingredient forces down, thiophene worm quinoline can contaminated air.Because the half life period is short, after getting into soil and water body, the residual matter of thiophene worm quinoline also can decompose fast, and very little to the influence that environment causes.
3. to aquatile safety.Thiophene worm quinoline is also very low to fish and other hydrobiological toxicity, generally to aquatile not influence basically.
4. to natural enemies security.Thiophene worm quinoline is very little, particularly very safe to honeybee and birds to the natural enemy influence, also can use trees and flowering phase of crop.
Thiophene worm quinoline suspending agent has possessed all characteristics of former medicine, also has simultaneously:
(1) better stability of preparation: the former medicine of thiophene worm quinoline is difficult to be dissolved in organic solvent, and the solvability in water is also very little, is well suited for to do aqueous suspension agent, and this product was placed 2 years at normal temperatures, and no bleed does not have deposition, and former medicine can not decompose.
(2) formulation is advanced, can be used for multiple use: thiophene worm quinoline aqueous suspension agent good dispersion in water, suspensibility height both be fit to large-area aircraft ultra low volume spraying, also were fit to the engine-driven atomiser spraying or the vehicular engine-driven atomiser spraying control of small size.
(3) resistance of rainwater washing against, the lasting period is long: the fineness of thiophene worm quinoline aqueous suspension agent can reach 3um, and adhesiveness is good on blade and branch, resistance of rainwater washing against, so the lasting period is longer, and saved dosage, indirect reduction drug cost.
(4) cost performance is high: because the control of thiophene worm quinoline suspending agent spectrum is very wide, a dispenser can solve the harm of various pests, has saved the cost and the time of repeated drug taking greatly.
Show that through large-area experiment and demonstration result thiophene worm quinoline suspending agent is remarkable to the control efficiency of Monochamus alternatus Hope adult, can be used for the control of large-area pine nematode.
Three, innovation and creation purpose
Agricultural chemicals is to the actual harm of environment, and is not only relevant with former medicine, also relevant with the formulation of agricultural chemicals.Maximum to the harm of environment with missible oil in the present employed formulations of pesticide, and suspending agent is owing to be that the former medicine of solid is suspended in the water, not with an organic solvent, major part is a water, so suspending agent is one of formulation of the environmental protection of agricultural chemicals.
In the use; The most drought and water shortage of northern longicorn generating region of China; In the pine nematode generating region of south except that the locality water shortage problem; Mountain region and knob account for agricultural and major part, especially forest, the trees of forestry land, mao bamboon is taller and bigger and the pesticide application medical instruments do not catch up with, and in control of insect, just face difficulty.Therefore press for a kind of efficient, low toxicity, low-residual, to people and animals, aquatic animal safety, biological agent easy to use solves the problem of longicorn control.
Four, technical scheme and invention effect, advantage
Proposition of the present invention is to fill up the control blind spot that domestic and international existing insecticide can not effectively be prevented and treated the communication media Monochamus alternatus Hope of pine wood nematode, prepares simultaneously a kind ofly can reach broad spectrum activity, safety, special effect agent efficiently.
