Abstract

A missible oil of permethrin-Bassa-malathion belongs to the broad-spectrum mixed insecticide. Its main effective components are permethrin, Bassa and malathion, and it is compounded with synergistic and emulsion and is built by making up the surplus with fluid wax. This invention is a high-effect, low-toxicity and low-residue broad-spectrum insecticide and is a new built farm chemical with excellent killing power of injurious insects of sting-suck and mouth-suck types and with contact killing and gastro-killing as the principal function. It can be widely used for cotton, vegetable, fruit, tea, tobacco and forest.

Description

Permethrin-bassa-malathion (jubama) missible oil

A kind of permethrin-bassa-malathion missible oil is called for short jubama missible oil (down together) and relates to technical field of pesticide, belongs to the broad spectrum insecticide mixture.

In order to improve the safety of agricultural chemicals, control is also eliminated residue of pesticide and is produced the pollution of emission to natural environment.The relevant rules increasingly stringent in various countries.The most noticeable in the insecticide is pyrethroids.The gross yield of states such as American and Britain, day, method has surpassed 500 tons (in 100% active ingredient) at present, and annual countries in the world are estimated to increase progressively 2.5% to the demand of pyrethroid.Extensive use the dichloro phenylate arranged, chrysanthemum ester cypermethrin, decis and the speed chrysanthemum ester that goes out, though their drug effects are high, the desinsection scope is wide, and is very safe again to environment, relatively poor to the acarid killing effect.(the mite class is various in style, and it is wide to distribute, the class pest that fertility is strong, harm is very big).Therefore, the acaricidal activity of raising pyrethroid becomes important exploitation problem.

At present used Pesticidal mixture made major part is two composite mixtures, obviously is better than single agent to the retarding action of pest resistance to insecticide development with to the preventive and therapeutic effect of insect pest.But the synergy amplitude of mixture and different exist the very big-differences of control efficiency because of component and proportioning.The disclosed a kind of agriculture chemical compounding agent of Chinese patent CN87101394.0 kills emulsion for cleaning for one times, be effective ingredient mainly with Belmark and phoxim, being equipped with suitable emulsifier and solvent complex and making, is composite dose of a kind of Synergistic fertilizer that is applicable to control vegetable-crop pest-insect, high-efficiency low-toxicity.The disclosed Pesticidal mixture made of CN90103780.X contains cypermethrin, malathion, synergy phosphorus, No. 30 machine oil, emulsifier and solvents.Though above-mentioned compound agricultural insecticide has better prevention insect effect, insect is difficult for producing drug resistance, synergistic effect is not remarkable, in use, can not reduce the consumption of effective ingredient.The application of composite lethane is more and more wider, and further exploitation is efficient, low toxicity, low-residual, and wide spectrum (effectively, safety, stable, multi-functional) is the needs of agricultural chemicals development

The objective of the invention is to overcome above-mentioned weak point, thus provide a kind of insecticidal spectrum wide, use wide medicament, the insect of multiple effect is had killing action, to sanitary insect pests such as mosquitos and flies, cockroach, bedbug also effective jubama missible oil.

Main solution of the present invention is achieved in that it mainly adopts Permanone, Ba Sha, malathion is effective ingredient, is equipped with synergist and emulsifier, and supplies surplus with liquid paraffin and carry out composite.In the effective ingredient: permethrin is 4.5-8.5%; Ba Sha is 7.5-13.5%; Malathion 12-18%.In the synergist: Octachlorodipropyl Ether is 4.5-8.5%; Synergy phosphorus is 12-19%.In the emulsifier: alkyl sulfide polyoxy alkene ether-10 is: 12-8%; Hexadecyltrimethylammonium chloride is 4-6%.

The jubama missible oil (trade name hundred worms are clear) that uses above-mentioned prescription to make is unique application cationic surfactant in the present domestic agricultural insecticide; In formulation of pesticide, adopt liquid paraffin without organic solvent, and the ternary built agent of utilization double increase agent.Co-toxicity coefficient of the present invention is 371.32, and composite dose of remarkable, a large amount of field trials of synergistic effect have proved its high efficiency and broad spectrum activity, and virulence LC50 is minimum to be 31.61PPM.

Following the present invention will be described further summary of the invention in conjunction with the embodiments: each component is in 100% (pure product) in this prescription.

Embodiment 1:

Getting Permanone is 4.5%, and Ba Sha is in the 7.5% input heating kettle, heating and melting, drop into mixing kettle again, getting the malathion is 12%, and Octachlorodipropyl Ether is 4.5%, synergy phosphorus is 12%, liquid paraffin is supplied surplus, and alkyl sulfide polyoxy alkene ether-10 is 12%, and hexadecyltrimethylammonium chloride is 4% to drop into mixing kettle together and mix and stir, by 80 order filtrations, shearing, emulsification, mixed storage mixes and stores, and is packed as finished product jubama missible oil.On April 9th, 96, with the dosage of jubama missible oil 25 gram/mus, extension rate is 3000 times, is used to prevent and treat the rice field rice weevil, and after the dispenser, lethality is 95.7%.

Embodiment two:

Getting Permanone is 6.5%, and Ba Sha is a heating and melting in the 10.5% input heating kettle, puts into mixing kettle again; Get malathion 15%, Octachlorodipropyl Ether is 6.5%, liquid paraffin supplies surplus and alkyl sulfide polyoxy alkene ether-10 is 15%, hexadecyltrimethylammonium chloride 5% drops into mixing kettle together and mixes stirring, by 80 order filtrations, shearing, emulsification, mixed storage, mix and store, be packed as jubama missible oil.Use the dosage of jubama missible oil 25 gram/mus in April, 96, and 3000 times of extension rates are used to prevent and treat citrus red mite, and control efficiency reaches 99%.

Embodiment three:

Getting Permanone is 8.5%, and Ba Sha is 13.5%, drops into heating and melting in the heating kettle, puts into mixing kettle again; Getting the malathion is 18%, Octachlorodipropyl Ether is 8.5%, liquid paraffin supplies surplus and alkyl sulfide polyoxy alkene ether-10 is 18%, hexadecyltrimethylammonium chloride is 6% to drop into mixing kettle together and mix to stir, by 80 order filtrations, shearing, emulsification, mixed storage, mix and store, be packed as jubama missible oil.Adopt the dosage of jubama missible oil 20 gram/mus in May, 96, extension rate is 5000 times, is used to prevent and treat " aulacophora femoralis " on the watermelon, and after the dispenser, 5 minutes, insect was promptly dead, and control efficiency is 98.8%.

The present invention has the following advantages:

1, the security of safety and low toxicity, this preparation is embodied in person poultry safety, low toxicity (rat footpath mouthful LD₅₀＞1500mg/KG) low-residual (longevity of residure 7-9 days, disable period 3-4 days);

2, purposes is wide, can be widely used in cotton, vegetables, melon and fruit, tealeaves, tobacco, forest and grass The aspect such as former;

3, be difficult for developing immunity to drugs, because this preparation is many components agricultural chemicals, so insect is difficult for producing resistance;

4, the no three wastes are free from environmental pollution, degrade rapidly at occurring in nature after the Main Ingredients and Appearance dispenser of this preparation, and environment is not polluted;

5, stable performance, owing to adopt new compound surfactant, stability of emulsion is good, but the shelf-life is 2 years, the missible oil storage root of Dahurian angelica is not stratified, does not precipitate, and keeps original emulsifiability and drug effect.

6, raw material sources are convenient, and cost is low, and every mu only needs 2.5-2.7 unit at every turn.

In sum, the present invention is efficient a, low toxicity, low-residual, broad spectrum pesticide.Insect to sucking mouth parts and biting mouthparts all has good killing power, is the novel agrochemical formulations of pest control, evil mite, based on tag, stomach extremely, have food refusal concurrently, kill ovum, the pupa killing effect.
