Abstract
The invention discloses an insecticide containing brassinolide and thiamethoxam. The effective active components of the insecticide are brassinolide and thiamethoxam, wherein the weight ratio of brassinolide to thiamethoxam is (0.001-50):(1-800). The insecticide disclosed by the invention realizes a synergistic effect on multiple pests harming the agricultural production; the dosage of pesticide can be reduced, the pesticide residue on crops is reduced, and environmental pollution is relieved; the insecticide is safe to human bodies and livestock and has good environmental compatibility; the pests do not generate drug resistance easily.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the insecticide of a kind of brassinolide-containing and Diacloden.
Background technology
Brassin lactones (brassinolide is called for short BR) is a kind of sterols plant hormone.Brassin lactones is applicable to cereal crops, economic crops, vegetables and fruit etc.; can promote growth; increase output, have that brute force is taken root, promoted growth, carries seedling, strong sprout, keeps a full stand of seedings, yellowtop leaf turns green, promote fertilization, flower and fruit protecting, promotion Fruit are precocious, alleviate that disease is alleviated poisoning, coordinated nutrient balance, drought resisting, cold-resistant, resist the multi-functionals such as saline and alkaline, enhancing crop anti-adversity.To the dead seedling causing because of reasons such as continuous cropping, disease, poisoning, freeze injury, salt damagies, rotten, vertical withered, the phenomenon of dampinging off first aid effect is remarkable, uses obviously to take effect for 12～24 hours, comes back to life, and recovers rapidly life.
Diacloden (Thiamethoxam), has another name called Acker Thailand, ACTARA, is a kind of nicotinoids broad spectrum pesticide of efficient, low toxicity, belongs to low toxic pesticide.Pure Diacloden is white crystalline powder, and preparation outward appearance is brown graininess.Diacloden has stomach toxicity, tags and systemic action insect; Be mainly used in preventing and treating Lepidoptera, diptera, coleoptera class pest, especially homoptera pest has high activity.Diacloden is as desirable in control efficiency such as aphid, plant hopper, leafhopper, aleyrodids to sucking pest.
The patent documentation that much contains the insecticide of brassin lactones or Diacloden is disclosed both at home and abroad.CN102910981A for example, disclose a kind of 8000UI/mg bacillus thuringiensis,Bt SC and preparation method thereof, under normal temperature, first dropped into organic phosphoric acid ester polyether and water, open high-speed shearing machine, speed with 2800 revs/min is uniformly mixed material, then drops into aluminium-magnesium silicate, xanthic acid, Sodium Benzoate, bacillus thuringiensis,Bt, ethylene glycol, silicone defoaming agent, xanthic acid, brassin, shears uniform stirring after half an hour, use the sand mill of three series connection to grind successively, after end, detect, qualified.The present invention adds and contains fulvic acid nutritional agents and each analog assistant obtains 8000UI/mg bacillus thuringiensis,Bt SC in formulation of pesticide, and this agricultural chemicals not only has insecticidal function, has also possessed the ability of fertilising.
For example CN103238619A, discloses a kind of Diacloden and imidaclothiz compounded pesticides, and its active ingredient comprises Diacloden and imidaclothiz, and all the other used additives or excipient complement to 100%, and wherein the part by weight of Diacloden and imidaclothiz is 1～85: 1～85.The multiple homoptera pest that this insecticide easily produces resistance to rice fulgorid, aphid, leafhopper, thrips etc. has good preventive effect, and suppresses insect single Diacloden and imidaclothiz preparation are developed immunity to drugs, and practical effect is remarkable.Utilize Diacloden and imidaclothiz composite to reaching the most of sucking pest of effective control, reduce the effect of environmental pollution, improve drug effect and lasting period simultaneously, reduced peasant's labour cost, there is good economic benefit.
At present, also do not find to take that brassinolide-containing and Diacloden are re-dubbed the Patents document of insecticide as active component.
Summary of the invention
The technical problem to be solved in the present invention is to provide the insecticide of a kind of brassinolide-containing and Diacloden, take brassin lactones and Diacloden as active component, various pests to harm agricultural production has synergistic effect, can reduce agricultural chemicals dosage, reduce the residual quantity of agricultural chemicals on crop, alleviated environmental pollution, to person poultry safety, Environmental compatibility is good, and insect is difficult for developing immunity to drugs.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
An insecticide for brassinolide-containing and Diacloden, its effective active composition is brassin lactones and Diacloden, the weight ratio of described brassin lactones and Diacloden is 0.001～50:1～800.
In such scheme, the preferred weight ratio of described brassin lactones and Diacloden is 1:800～3000.
In such scheme, the optimum weight ratio of described brassin lactones and Diacloden is 1:2000.
Further, described insecticide, except containing the brassin lactones and Diacloden as active ingredient, also contains the pesticidal preparations auxiliary elements such as auxiliary agent.Now, the composition that the insecticide in such scheme comprises following percentage by weight: brassin lactones 0.0001%～5%, Diacloden 0.1%～80%, auxiliary agent 5%～20%, surplus is one or more in demineralized water, solvent or filler.
Further, described auxiliary agent is agricultural agent conventional in this area, can be selected from one or more in aliphatic acid polyethenoxy ether, calcium dodecyl benzene sulfonate, phenethyl phenol polyethenoxy ether, alkylphenol-formaldehyde resin polyvinyl sulfonate, dodecyl sodium sulfate, aluminium-magnesium silicate, xanthans.
Further, described solvent is agriculture medicinal organic solvent conventional in this area, can be selected from one or more in dimethylbenzene, cyclohexanone, isopropyl alcohol.
Further, described filler is agricultural chemicals filler conventional in this area, for example kaolin or starch.
According to the composition of pesticidal preparations auxiliary element and the difference of addition of adding, the formulation of described insecticide can be aqueous emulsion, microemulsion, suspending agent, granule, wetting powder or water dispersible granules.
The present invention has the following advantages:
1, to take brassin lactones and Diacloden be active component in the present invention, developed a kind of new pesticide species;
2, brassin lactones of the present invention and Diacloden are after composite, to preventing and treating disease, there is excellent synergistic function, can improve control efficiency, anti-eliminate aphis, the insect such as thrips effective, reduced pesticide dosage, brassin lactones also can play the effect of plant growth regulator, can improve the output of crop;
3, this insecticide toxicity is lower, residual less, uses safety, is conducive to protect person poultry safety, and to the infringement of ecotope with pollute littlely, insect is difficult for developing immunity to drugs.
