Abstract

本发明是一种含柴油的植物保护杀虫、杀螨剂,其特点是将柴油以及其它农药、乳化剂、渗透剂按一定比例混配制成复方制剂,所述的其它农药包括阿维菌素、浏阳霉素、有机磷类、氨基甲酸酯类、拟除虫菊酯类以及有关的化学农药。本发明利用柴油具有封闭昆虫呼收气孔以及促进农药向作物和昆虫表皮细胞渗透作用,从而使农药充分发挥药效,同等含量时防效可提高0.5—2.5倍,这样就可以减少大田农药使用量,从而减少化学农药对环境的污染,也降低了生产成本。The invention is a plant protection insecticide and acaricide containing diesel oil, which is characterized in that diesel oil and other pesticides, emulsifiers and penetrating agents are mixed in a certain proportion to form a compound preparation, and the other pesticides include abamectin , Liuyangmycin, organophosphates, carbamates, pyrethroids and related chemical pesticides. The invention utilizes diesel oil to close insect exhalation pores and promote the penetration of pesticides into crops and insect epidermal cells, so that the pesticides can fully exert their efficacy, and the control effect can be increased by 0.5-2.5 times when the content is the same, so that the amount of pesticides used in the field can be reduced , thereby reducing the pollution of chemical pesticides to the environment, and also reducing production costs.

Description

The insecticide that a kind of plant protection that contains light diesel fuel is used

The present invention relates to the insecticide of the hydrocarbon-containifirst that plant protection uses, more particularly, is a kind of Insecticidal and acaricidal agent by light diesel fuel and other agriculture chemical compounding.

Itself has certain insecticidal activity diesel oil, it is strong to insect epidermis penetration, can react with pest body inner cell matter, can also on polypide, form oil film, sealing insect body surface is used to exhale the getter hole, insect is suffocated, can impel the epidermal cell infiltration of other agricultural chemicals in composite dose again, thereby the drug effect of giving full play to and prolong drug effect improves the effective rate of utilization of Recompounded pesticide to crop and insect, save the consumption of agricultural chemicals, reduce residually, reduce environmental pollution (" newly organized agricultural chemicals handbook sequel ", Chinese agriculture publishing house, 1998, P202-206).

The objective of the invention is the characteristic of utilizing diesel oil to have, make that a kind of cost is low, the agricultural insecticidal that contains diesel oil of good drug efficacy, kill the mite mixed emulsifiable solution.

The objective of the invention is to realize: diesel oil, other agricultural chemicals, emulsifier, bleeding agent, solvent are prepared into missible oil by following technical proposals.

Missible oil of the present invention is concrete to be formed and content (percetage by weight):

Diesel oil 3-70%, other agricultural chemicals 0.05-40%, emulsifier 3-50%, bleeding agent 0-5%, other is a solvent.

Diesel oil of the present invention is that boiling range that PETROLEUM PROCESSING obtains is 200-380 ℃ a light diesel fuel, comprises commercially available 0-10 diesel oil.

Other agricultural chemicals of the present invention comprise bromine cyanogen bacterium ester in A Wei chrysanthemum element, macro tetrolide, organic phosphates, carbamates, the pyrethroid class, beta-cypermethrin, brofluthrinate, cyfluthrin bacterium ester, sumicidin with and comprise other chemical pesticide of Imidacloprid, Amitraz, azacyclotin.

Described Avermectin is the tunning of A Foman streptomycete (Streptomyces avermitilis), is AvermectinA by the mixture of forming of the quite similar homology of eight structures _1a, A _1b, A _2a, A _2b, B _1a, B _1b, B _2a, B _2b, generally use B more _1a, B _1bMixture, it can adopt existing technology extract and separate (William C.Campbell. " Ivermectin and Abamectin ", Springer-Verlag, New York Inc, 1989, P1-3).

Described macro tetrolide is the mite farm antibiotics extremely that is produced by streptomyces griseus Liuyang mutation Streptomyces griseusvar liuyanggensis fermentation, by five components is tetranactin, trinactin, dinactin, monactin, nonactin forms (" newly organized agricultural chemicals handbook sequel ", Chinese agriculture publishing house, 1988, P87-89).

Described organophosphorus insecticide comprises that chlopyrifos, chlorpyrifos-methyl, isocarbophos, fenthion, carbamate comprise carbosulfan, Methomyl, pyrethroid class (comprising decis, beta-cypermethrin, brofluthrinate, cyfloxylate, sumicidin) and other chemical pesticide that comprises Imidacloprid, Amitraz, azacyclotin.

Emulsifier of the present invention comprises Tween-80,0203B and comprises OP-10 and the OP series of OP-21.

Bleeding agent of the present invention comprises JFC, is the commercially available prod.

Solvent of the present invention comprises dimethylbenzene, ethanol, acetone, isopropyl alcohol.

Method for producing insecticide of the present invention: at first dissolve other agricultural chemicals with partial solvent, add emulsifier again, stir evenly the solvent that the back adds diesel oil and surplus, mixing promptly obtains required cream pesticide.

Missible oil of the present invention is taked the using method used always: carry out constant, low volume or direct ultra low volume spray behind the dilute with water; Also spray behind the dilutable water or brush.

The major advantage of insecticide of the present invention:

Insecticide of the present invention is exhaled getter hole and the insect cuticle Premeabilisation of cells effect that promotes agricultural chemicals to crop owing to utilize diesel oil to have the sealing insect, therefore less agricultural chemicals dosage obtains the better effect of common using dosage, during equal pesticide concentration, preventive effect can improve 0.5-2.5 doubly, so just can reduce the usage amount of agricultural chemicals, thereby reduced production cost, reduced the pollution of chemical pesticide environment.Insecticide of the present invention can be used for preventing and treating insect and the evil mite on the crops such as vegetables, fruit tree, cotton, flowers, tobacco.

Further describe characteristics of the present invention below by example.

Example 1
