Abstract
The invention relates to a compound pesticide with the effective and active components being tetrachlorvinphos and triflumuron, comprising the effective and active components, an auxiliary agent and a solvent. The compound pesticide is characterized in that the effective and active components comprise the tetrachlorvinphos and the triflumuron. The weight mixture ratio of the tetrachlorvinphos to the triflumuron is (1-20):(1-40). After the tetrachlorvinphos and the triflumuron are compounded, the invention has the obvious effects of synergia and persistent prevention and treatment, multi-functional pesticide with high efficiency and persistent effect to rice leaf roller pests is obtained, the medicament dosage, the drug delivery frequency and the application cost are remarkably lowered, and the generation of the drug resistance of the pests is relieved.
Description
Technical field:
The invention belongs to control pest agricultural chemicals, relating to a kind of effective active composition is that indenes worm prestige is killed earworm urea compounded pesticides.
Background technology:
Chemical pesticide is that one of primary armament of high crop yield is struggled, captured to peasant and insect, also coming kill pests by spraying agricultural chemicals inevitably in for a long time from now on, improves crop yield.
In order to protect food security; the protection environment; the protection human beings'health; the research and development of agricultural chemicals are just striden along towards efficient, long-acting, low toxicity, low-residual direction with application; researchers at different levels have been done fruitful effort for it, and new, as to be subjected to that society welcomes efficient, long-acting, low toxicity, the pesticide species of low-residual constantly occur.
Continuous appearance new, that be subjected to the agricultural chemicals of society's welcome will be updated the agricultural chemicals use habit, comprise being used alternatingly agricultural chemicals.For delaying the pesticide resistance of insect, protect useful natural enemy, finally reduce the usage amount of agricultural chemicals, new approach is provided.
Indenes worm prestige (indoxacarb) rat acute per os LD
501732mg/kg (hero) has and tags and stomach poison function, and is all effective to each instar larvae, sodium-ion channel by in the blocking-up insect nerve cell makes the nerve cell loss of function, mainly prevents and treats insects such as Lepidoptera, dead in 24-60 hour behind the medicine, safer to natural enemy insect.
Kill bell urea (chlorobenzuron) rat oral LD
50＞5000mg/kg is an insect chitin synthetic inhibitor insecticides, based on stomach poison function, certain action of contace poison is arranged, but do not have systemic action, insecticidal effect is preferably arranged, this medicine has special efficacy to lepidoptera pest etc., enters dead worm peak in 4-5 days behind the medicine, to natural enemies security.
Use above-mentioned a kind of agricultural chemicals separately, not only the pest control cost is higher, is repeatedly used the pesticide resistance that also can bring out insect, influences drug effect.
Agricultural chemicals is reasonably composite to be raising preventive effect, expanding prevention object, delay a kind of effective ways that pest resistance to insecticide produced, reduced environmental pollution, reduces residue of pesticide.Through screening, with indenes worm prestige with kill the bell urea and carry out compositely, can realize above-mentioned a series of advantages.
Summary of the invention:
The objective of the invention is to:, provide a kind of indenes worm prestige to kill the composite insecticide of bell urea at using at present separately indenes worm prestige, killing that cost is higher in the bell urea pest control process, preventive effect is on the low side, the medicament frequency of utilization is higher and easily bring out the practical problem that insect develops immunity to drugs.
The object of the present invention is achieved like this: a kind of compound pesticide of tetrachlorvinphos and triflumuron, comprise effective active component, and auxiliary agent and solvent is characterized in that: the effective active composition is indenes worm prestige and kills the bell urea that indenes worm prestige is 1-20: 1-40 with the weight ratio of killing the bell urea.
Indenes worm prestige is 1%-80% with the active constituent content that kills the bell urea in the compound insecticidal agent formulation finished dosage forms that the present invention relates to, auxiliary agent 5-20%, and all the other are solvent.
In the compounded pesticides that the present invention relates to, the formulation of compound pesticide of tetrachlorvinphos and triflumuron is missible oil or suspending agent.
The invention has the advantages that: indenes worm prestige with kill the bell urea composite after, obtained the notable synergistic effect to rice leaf roller, the quick-acting of desinsection is remarkable, the lasting period prolongation, has reduced dosage, spraying times and drug cost, hang down pollution, low-residual, and delayed the generation of pest resistance to insecticide.
Embodiment:
In each of the embodiments described below, the former medicine of indenes worm prestige Shanghai Nongle Biological Product Co., Ltd. (du pont company); Killing the former medicine of bell urea is produced by Tonghua, Jilin Province pesticide chemical limited company.
Embodiment 1
(1) 10% indenes worm prestige is killed the preparation of bell urea missible oil (active drug quality proportioning 1: 1), and auxiliary agent is selected DMF, and solvent is selected toluene.Each component is got the raw materials ready by mass percentage: indenes worm prestige 5%, kill bell urea 5%, about DMF8%, acetone about 5%, solvent toluene is an amount of.
(2) process for preparation: with indenes worm prestige acetone solution, add successively again and kill bell urea, DMF, be filled to 100% with toluene then.Said mixture is mixed in dissolve measuring bottle, 10% indenes worm prestige kill bell urea missible oil.
Embodiment 2
(1) 10% indenes worm prestige is killed the preparation of bell urea suspending agent (active drug composition weight proportion 2: 3), auxiliary agent is selected ethylene glycol, organic silicone, sodium lignin sulfonate, agricultural newborn 0201B, white carbon, solvent is selected water, and each compositions in weight percentage is got the raw materials ready: indenes worm prestige 4.0%, kill bell urea 6.0%, dispersant sodium lignin sulfonate 9.0%, the newborn 0201B 4.0% of wetting agent farming, thickener white carbon 1.0%, antifreeze glycol 5.0%, defoamer organic silicone 0.01%, surplus are water.
(2) process for preparation: with indenes worm prestige, kill bell urea, sodium lignin sulfonate, agricultural newborn 0201B, thickener white carbon, antifreeze glycol, place reactor according to the above ratio, water adds to 100%, mix again mixture is introduced in the sand mill, being milled to the material fineness is 2-5 μ m, mix after milling suspending agent.
