Abstract

The present invention is a kind of desinsection, miticide, with the crude cotton seed oil is primary raw material, in the sodium soap saponification liquid of crude cotton seed oil and sodium hydroxide reaction generation, add stabilizing agent, turpentine oil, insecticide, synergist etc. are combined into a kind of efficient, low toxic pesticide, this agricultural chemicals is to tag, stifling is main, solved existing agricultural chemicals to containing the shortcoming that the wax insect lacks molten wax effect, has good disinsection effect, spray in three days the killing rate average out to more than 90%, cost is low, and remarkable in economical benefits is pollution-free, being particularly useful for the control of fruit tree diseases and pests, is a kind of composite agricultural chemical that suits large area to popularize.

Description

A kind of emulsified oil of meta-tolyl-N-methyl-carbamate

The invention belongs to the preparation technique field of Insecticidal and acaricidal agent agricultural chemicals, is primary raw material with ore deposit, vegetable oil, adds compositions such as stabilizing agent, synergist in right amount and is combined into a kind of emulsified oil of meta-tolyl-N-methyl-carbamate.

In the prior art, for anti-cure the disease, worm, bacterium be to the harm of crops or in order to promote crop growth, the organic agricultural chemicals of people's synthetic commonly used, organic complex compound that elements such as its Main Ingredients and Appearance is mostly phosphorous, chlorine, sulphur, arsenic, mercury are formed.As parathion (1605), malathion, chlorophos, zineb, acephatemet, Belmark etc.Because the high poison of these agricultural chemicals.The safety that residual hazard is big, cost is high, particularly parathion usually jeopardizes people and livestock, when these pesticide sprayings on fruit class plant, usually can cause adverse consequences because of eating by mistake in the maturing stage, therefore existing pesticide variety is difficult to adapt to some fruit class plant and prevents damage by disease and insect in the phase of bearing fruit, as cabbage caterpillar and the tea caterpillar of apple, peach fruit borer, mite class, vegetables, cluster caterpillar; The cotton aphids of sugarcane etc., these agricultural chemicals lack molten wax effect to the insect that thrips, liver moss, cotton bollworm, lichens etc. contain wax in addition, can not satisfy the needs of cultural control damage by disease and insect.

The objective of the invention is to overcome the deficiencies in the prior art part and the composition of can desinsection, can kill mite is provided, this composition low toxicity, cost are low, residual hazard is a kind of emulsified oil of meta-tolyl-N-methyl-carbamate applied widely for a short time.

Another object of the present invention is to have overcome the shortcoming that existing agricultural chemicals lacks molten wax effect, provides a kind of molten cured matter effective emulsified oil of meta-tolyl-N-methyl-carbamate.

Above-mentioned purpose of the present invention is achieved in that emulsified oil of meta-tolyl-N-methyl-carbamate comprises turpentine oil emulsifier and ore deposit, vegetable oil sterilization, agrochemical.It is characterized in that emulsifier turpentine oil, insecticide light diesel and stabilizer alcohol add crude cotton seed oil and sodium hydroxide generates a kind of new emulsified insecticide by height saponification and oxidation reaction, synergist goes out and sweeps profit, carbon disulphide (CS ₂) and carbon tetrachloride (CCl ₄) add in the emulsified insecticide and be combined into the composite agricultural chemical emulsified oil of meta-tolyl-N-methyl-carbamate after the reaction, the present invention is to be primary raw material with the crude cotton seed oil, because of crude cotton seed oil includes gossypol and fatty acid composition, have insecticidal effect but belong to acidic materials, unstable, generate stable sodium soap saponification liquid after through height saponification oxidation with the sodium hydroxide reaction.Insecticidal effect is more obvious, permanent, add light diesel again, pine tar oil and ethanol make it to generate a kind of emulsified insecticide, go out and sweep profit, carbon disulphide and carbon tetrachloride but add synergist again because of the effect of emulsified insecticide is low, be combined into a kind of composite agricultural chemical of high-efficiency low-toxicity.

The present invention is stifling to tag, and have very strong interior absorption, adhesivity and permeability concurrently, wax coat to insect has strong corrosiveness, so elimination is contained the insect best results of cured matter, through evidence, killing rate of the present invention reaches more than 95%, and prevention and treatment range is wide, is applicable to the white-backed planthopper in mite class, cotton bollworm and two spotted spider mite, cotton aphid, the paddy rice, brown planthopper in the cotton crop; The control of damage by disease and insect such as the peach fruit borer of the cabbage caterpillar in the vegetables, diamond-back moth, apple, mite class.

Each set of dispense ratio of the present invention is to calculate 15 kilograms of crude cotton seed oils, 0.5 kilogram in water, 40Be by the emulsified insecticide proportioning of producing 130 kilograms ⁰9 kilograms in sodium hydroxide, 20 kilograms in turpentine oil, 80 kilograms of light diesels, 10 kilograms of 70% ethanol, on the basis of above each component overall weight, precentagewise proportioning synergist goes out and sweeps profit, carbon disulphide (CS ₂) and carbon tetrachloride (CCl ₄), its proportioning is swept sharp 3-4%, carbon disulphide (CS for going out ₂) be 1.5%, carbon tetrachloride (CCl ₄) 1%.The reaction of crude cotton seed oil and sodium hydroxide should be carried out at normal temperatures, and saponification time should be not less than 48 hours, and oxidization time should be not less than 2 hours, makes it fully could prepare other compositions after the reaction.

Embodiment: when 130 kilograms of emulsified insecticides of preparation, in reaction vessel, add 0.5 kg water in proportion earlier, add 15 kilograms of crude cotton seed oils then, 40Be ⁰9 kilograms in sodium hydroxide, fully carry out 50 hours saponification and 3 hours oxidation reaction after stirring evenly, then in saponification liquor, add 80 kilograms of diesel oil again, with 20 kilograms in turpentine oil, fully stir evenly leave standstill 30 hours after, add again 10 kilograms of 70% stabilizer alcohols and synergist go out sweep profit, carbon disulphide, carbon tetrachloride, after above each component preparation finishes, until obtain solution the no oil slick in surface with do not have to precipitate and can think and react completely.This missible oil is light brown oily liquids, the 600-1000 of being made into soluble in water even milky white liquid doubly, be made into best results about 800 times according to experiment, during use, consumption in accordance with regulations, adding suitable quantity of water is stirred into milky white liquid and can sprays, because of this medicine belongs to alkaline solution, can not mix use with acid agrichemical.

The present invention compared with prior art has good disinsection effect, it is average more than 90% to spray in rear three days insecticidal effect, especially better to the fruit tree pest control effect, and cost is low, remarkable in economical benefits, reduce cost about 60% than existing agricultural chemicals, low toxicity, pollution-free is a kind of composite agricultural chemical that suits large area to popularize and use.
