Abstract
The name of the invention is thiamethoxam for preventing and treating forestry defoliators. The invention belongs to the agricultural science in terms of disciplines, the agricultural field in terms of technologies, and the subfield of plant protection. In the invention, a thiamethoxam original drug is compounded into certain dosage forms, such as powder or wettable powder, for preventing and treating forestry defoliators, which are mainly pine caterpillar larvae, Clostera anachoreta larvae and Hyphantria cunea larvae, etc. And the dosage of per 667 square meters (or 1 mu) is 1.5-3g. The thiamethoxam of the invention not only has a good quick-acting insecticidal effect, but also has a wide insecticidal spectrum, is safe to human, livestock, natural enemies of pests and other beneficial organisms, and avoids environmental pollution caused by a large number of organic solvents. Characterized by simple preparation process and low cost, the invention is suitable for promotion and application.
Description
One, technical field
Ambit is an agricultural science under this patent, and affiliated technical field is an agricultural, and the segmentation field is plant protection.
Two, background technology
Thiophene worm piperazine is called Acker Thailand again, and English name thiamethoxam is anabasine insecticide, be by Novartis Co.,Ltd in successful development in 1991, one of latest generation high-efficient broad-spectrum insecticide of listing in 1997.Pure article are white crystalline powder, 139.1 ℃ of fusing points, vapour pressure, 6.6 * 10
-9Pa (25 ℃) belongs to low toxic pesticide, and rat acute per os LD50 is 1563mg/kg, and these article are to exempting from eyes and skin has no stimulation.The mechanism of action of thiophene worm piperazine is similar with Imidacloprid, alternative inhibition insect central nervous system nicotinic acid acetylcholinesterase acceptor, and then the normal conduction of blocking-up insect central nervous system, and it is dead to cause insect paralysis to occur.Not only have tag, stomach toxicity, systemic activity; And have higher activity, better safety, wider insecticidal spectrum and characteristics such as speed of action is fast, the lasting period is long, be the better kinds that replace those are high to mammalian toxicity, residual and environmental problem are arranged organic phosphor, carbamate, organochlorine insecticides.To coleoptera, diptera, Lepidoptera; Especially homoptera pest has high activity, can effectively prevent and treat the insect that insect such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and knot polytype chemical pesticide produce resistance.There is not cross resistance with Imidacloprid, Acetamiprid, Nitenpyram.Both can be used for cauline leaf processing, seed treatment, also can be used for soil treatment.Suitable crop is rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.Under RD, use crop safety, no poisoning.
The agricultural chemicals of control defoliator mainly contains AVM, first dimension salt, pyrethroid pesticide, go out young urea, fenoxycarb, matrine, nicotine, bacillus thuringiensis etc. in forestry at present, and these pesticide species all have certain disadvantages: first dimension salt and AVM cost are too high; The young urea desinsection speed of going out is too slow; It is too fast that pyrethroid pesticide produces resistance, but also the people is had stronger excitant; Matrine, nicotine, bacillus thuringiensis insecticidal activity are low, and desinsection speed waits slowly.Comprehensive relatively, thiophene worm piperazine has the unexistent advantage of above pesticide species: desinsection is quick-acting, with low cost, be difficult for developing immunity to drugs etc., and thiophene worm piperazine is relatively safe, and is less to the environment side effect.Also have the insecticidal spectrum of thiophene worm piperazine wider, not only efficient to homoptera pest, also higher to Lepidoptera, coleopteran pest virulence.Therefore, the author is used for preventing and treating the forestry defoliator through consulting lot of documents and on the basis of field trial, having invented the pulvis of thiophene worm piperazine and the prescription of wetting powder.
Three, summary of the invention
This patent invention is thiophene worm piperazine to be processed preparation be used for preventing and treating the forestry defoliator; Thiophene worm piperazine is a second generation anabasine pesticide, mainly is used for anti-eliminating aphis, homoptera pests such as trialeurodes vaporariorum, rice fulgorid, up to the present; Also not seeing has report to have to use thiophene worm piperazine to prevent and treat lepidoptera pest; In fact, thiophene worm piperazine not only has very high activity to homoptera pest, and outstanding too to the control efficiency of Lepidoptera and coleopteran pest.The author is on the basis of consulting lot of documents and a large amount of woodland tests, and invention thiophene worm piperazine pulvis and thiophene worm piperazine wetting powder are used for preventing and treating forestry defoliators such as pine caterpillars, poplar caterpillar, fall webworm.
The prescription of pulvis consists of: thiophene worm piperazine 0.2-10%, dispersant sodium lignin sulfonate 2-3%, filler talcum powder or kaolin complement to 100% (percentage in the prescription composition is weight ratio).
The prescription of wetting powder consists of: thiophene worm piperazine 6-10%, detergent LS 6-8%, wetting powder special assistant 2-3%, wetting agent lauryl sodium sulfate 2-3%, white carbon 2-3%, kaolin complement to 100% (percentage in the prescription composition is weight ratio).
Forestry pest mu dosage 1.5-3 grams (being converted to the former medicine of 100% content) such as control pine caterpillars, poplar caterpillar, fall webworm.
Four, description of drawings
Accompanying drawing is thiophene worm piperazine control forestry defoliator research and development process charts.
Five, embodiment
1, preliminary indoor medicament is given birth to survey, measures the activity of thiophene worm piperazine to pine caterpillars larva, poplar caterpillar larva, fall webworm larva;
2, survey the result according to indoor giving birth to, debugging prescription sample;
3, woodland is given birth to and is surveyed, and confirms thiophene worm piperazine mu dosage;
4, debugging prescription;
5, workshop pilot scale;
6, mass production;
7, the various places experiment and demonstration is promoted;
8, product is released market.
Claims (4)
1. to be to adopt second generation nicotinic insecticide thiophene worm piperazine be primary raw material to thiophene worm piperazine control forestry defoliator principal character, and thiophene worm piperazine has characteristics such as desinsection is quick-acting, insecticidal spectrum wide, safety and environmental protection.Thiophene worm piperazine is not only to vertebrate low toxicities such as people, animal; And it is very friendly to environment; Not contaminated air, water source; Also do not kill and wound beneficial organisms such as honeybee, birds, fish, shrimp, it is very strong that thiophene worm piperazine is knocked down power to lepidoptera pest, is suitable for the control of forestry Lepidoptera defoliators such as pine caterpillars, poplar caterpillar, fall webworm.
2. prescription according to claim 1, the content that it is characterized in that Acetamiprid are 0.2-10% (weight ratio).
