Abstract
The invention relates to a synergistic pesticide composition of ivermectin and chitosan oligosaccharide. The synergistic pesticide composition is characterized by being prepared from the ivermectin and the chitosan oligosaccharide which serve as active ingredients, and a pesticide aid, wherein the mass ratio of ivermectin to the chitosan oligosaccharide is (1:0.01)-(1:100), preferably (1:0.1)-(1:50), and optimally (1:1)-(1:10). The synergistic pesticide composition can be used as water aqua, a suspending agent, wettable powder, aqueous dispersion granules, missible oil and water emulsion, and is used for preventing and controlling rice leaf folder. By the synergistic pesticide composition, the pesticide resistance of injurious insects is overcome and delayed; and the complexed synergistic pesticide composition has a synergistic effect, and is safe in application and environment-friendly.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the synergetic pesticide composition of ivermectin and chitosan oligosaccharide.
Background technology
Rice leaf roller is a kind of migratory pest, from north and 1 ~ 11 generation occured Nan Yinian.Ministry of Agriculture's prediction, rice leaf roller has maintained higher level always since national breaking out occured in 2003, and year generation area is more than 300,000,000 mu.Show as: the peak increases, and the main peak that moves increases; Occurrence scope enlarges, area change; The field generation overlap is serious, and harm time is long; The south of the River, the middle and lower reach of Yangtze River, southwestern northeast occur year after year.
Ivermectin is take Avermectin as lead compound, by two key hydrogenations, and structure optimization and the novel synthetic pesticide succeeded in developing.Structure optimization product as agricultural antibiotic, compare with the parent Avermectin, its expelling parasite and acaricidal activity have not only been kept, and safety is higher, be difficult for to produce resistance, for the production of vegetables, fruit, cotton etc. provides efficient a, high security and eco-friendly agricultural insecticidal miticide.Ivermectin has stomach toxicity and action of contace poison, and the horizontal infiltration conduction is arranged, and insect, mite class and nematode are killed effect.
Chitosan oligosaccharide is the product of chitin or shitosan decomposed, is a class by N-acetamide and glucose or the Glucosamine carbohydrate by the low polymerization degree (3-10) that β-the Isosorbide-5-Nitrae glycosidic bond couples together.Compare with this large biological molecule of chitin and shitosan, it has unique physiologically active and function, such as water-soluble, moisture retention, antibiotic property, antitumor and immune promotion etc.Recent study finds can be used as a kind of inducible factor, the expression that improves plant self-defense enzyme is had certain effect, but the immunity of Effective Raise crop, and the raising of this immunity does not cause the retardation of plant growth, the growth of crop is not produced poisoning yet, and chitosan oligosaccharide itself is nontoxic, so can not produce medicament residue to the fruit of crop harvesting.
Be used alone active ingredient, insect easily develops immunity to drugs.Therefore, the composite use of ivermectin and chitosan oligosaccharide can reduce the dosage of active ingredient, plays the effect that improves preventive effect, delays pest resistance to insecticide.
Summary of the invention
The present invention is the synergistic composition of ivermectin and chitosan oligosaccharide.Can effectively prevent rice leaf roller.The two composite dosage that reduces active ingredient delays pest resistance to insecticide.
The present invention is the synergistic composition of ivermectin and chitosan oligosaccharide, it is characterized in that: the active ingredient take ivermectin and chitosan oligosaccharide as composition is aided with that insecticides adjuvant is composite to be formed.Wherein, the mass ratio of ivermectin and chitosan oligosaccharide is 1:0.01 ~ 1:100, is preferably 1:0.1 ~ 1:50, and the best is 1:1 ~ 1:10.
Described composition pesticide formulation is aqueous emulsion, soluble liquid, aqua, suspending agent, wetting powder, water dispersion granule, missible oil.
Described composition pesticide is used for control paddy rice rice leaf roller.
Specific embodiment
Embodiment 1 preparation 10.5% ivermectin chitosan oligosaccharide aqueous emulsion
Active ingredient mass percent (%): ivermectin: chitosan oligosaccharide is 10:0.5
Auxiliary agent mass percent (%): emulsifier: lignosulfonates 5.0; Thickener: gum Arabic 2.0, xanthans 0.5; Antifreezing agent: sorbic acid 5.0; Defoamer: efficient polysiloxanes 0.2; Preservative: potassium sorbate 2.0; Solvent: diesel oil 10.0; The surplus deionized water.
Embodiment 2 preparations 20% ivermectin chitosan oligosaccharide soluble liquid
Active ingredient mass percent (%): ivermectin: chitosan oligosaccharide is 19:1
Auxiliary agent mass percent (%): surfactant: anhydrous sorbitol APEO 11.0; Antifreezing agent: glycerine 2.0; Solubilizer: ethyl acetate 15.0; Solvent is supplied surplus.
In order to verify 10.5% ivermectin chitosan oligosaccharide aqueous emulsion and 20% ivermectin chitosan oligosaccharide soluble liquid to the control efficiency of rice leaf roller, carried out the effect control experiment of field, land for growing field crops.
Table 1 10.5% ivermectin chitosan oligosaccharide aqueous emulsion and to the control efficiency of rice leaf roller
By table 1 result as can be known, the composite control efficiency to rice leaf roller of ivermectin and chitosan oligosaccharide is apparently higher than the imitation of independent use ivermectin, this shows that the present invention makes up and has obvious synergistic effect.
