Abstract

The present invention discloses a compounded pesticide for killing moth and killing aphid, and its raw material composition contains (wt%) 2-10% of imidacloprid, 10-25% of chlorbenzuron and proper quantity of filling material and adjuvant. Said invented compounded pesticide possesses obvious action for controlling apple leaf miner and apple aphid, and its control effect is above 90%, and its co-toxic coefficient is greater than 200, so that it possesses obvious synergistic action, its toxicity is low and its control cost also is low.

Description

A kind of Recompounded pesticide of killing moth and aphis

The present invention relates to a kind of agricultural chemicals, refer in particular to a kind of Recompounded pesticide (trade name: EYaLing) of killing moth and aphis.

In prior art, on the fruit tree generations such as second generation apple leaf miner (late May) larva and apple yellow aphid close period, all need prevent and treat every year, and twice medication.The young urea that goes out that my company produces is for No. 3 the best good medicine of control apple leaf miner, is the jinx of phosphorus wing order insect; And Imidacloprid on sale is one of the most desirable medicament of control apple yellow aphid, spiraea aphid on the market.In order to prevent and treat above-mentioned two kinds of insect apple leaf miners and apple yellow aphid, the orchard worker will be sprayed medicine respectively, causes the orchard worker repeatedly to look for the medicine control, and is time-consuming expensive.

The objective of the invention is provides a kind of a drug the double simultaneously Recompounded pesticide of controlling the killing moth and aphis of moth, two kinds of insects of aphid at above-mentioned deficiency.

The object of the present invention is achieved like this: the Recompounded pesticide of killing moth and aphis, form by following raw materials by weight percent: and Imidacloprid 2-10%, No. 3 10-25% of young urea that go out, filler, auxiliary agent are an amount of.According to using needs, can be re-dubbed wetting powder, suspending agent, missible oil etc.

Described auxiliary agent is diffusant 1-3%, bleeding agent 5-10%, and white carbon 10-20%, surplus is a carclazyte, makes wetting powder through pulverizing certain fineness.

Described auxiliary agent is emulsifier 10-25%, dimethyl formamide 30-40%, dimethylbenzene is supplied surplus, the powerful stirring, filter finished product missible oil.

Described auxiliary agent is emulsifier 10-25%, bleeding agent 5-10%, and white carbon 10-20%, ethylene glycol 5%, surplus is a water, grinds after pulling an oar and forms suspending agent.

Method for making: will stipulate the Imidacloprid of ratio, No. 3, the young urea of going out, filler, auxiliary agent add successively and are mixed, and break into corresponding dosage forms, are packaged as finished product after the assay was approved.

Working concentration: 1000-2500 times liquid.

Through " this pesticide sample that the Ministry of Chemical Industry's chemistry security evaluation supervision and inspection " center " send my company detects the examining report of being provided and shows:

1, " but 25% EYaLing wet-milling acute skin irritation test is reported " shows: but 25% EYaLing wet-milling is " nonirritant " to skin irritatin intensity.

2, " but 25% EYaLing wet-milling acute dermal toxicity test report " shows: but the acute dermal toxicity of 25% EYaLing wet-milling belongs to " low toxicity ".

3, " but 25% EYaLing wet-milling acute oral toxicity test is reported " shows: but the acute oral toxicity of 25% EYaLing wet-milling belongs to " low toxicity ".

4, " but 25% EYaLing wet-milling eye irritant test is reported " shows: but the eye stimulus intensity of 25% EYaLing wet-milling is classified as " slight excitant ".

This pesticide sample that my company is sent through " coming plant protection system of positive agricultural college " detects the examining report of being provided and shows:

" 25% EYaLing wetting powder is measured report to the apple yellow aphid co-toxicity coefficient " shows: 25% EYaLing wetting powder is 209.99 to the co-toxicity coefficient of apple yellow aphid, belongs to notable synergistic.

This pesticide sample that my company is sent through " Fruit Institute, Chinese Academy of Agricultural Sciences " detects the examining report of being provided and shows:

1, " the 25% EYaLing wetting powder control apple apple leaf miner test of pesticide effectiveness is reported " shows: 25% EYaLing wetting powder has good drug effect to the apple apple leaf miner.1500-2500 times of liquid of Sheng phase sprinkling EYaLing just takes place field adult or ovum, control efficiency is all more than 90%, the phase is effectively controlled more than 15 days in the field, obviously be better than or be equivalent to the special agent 25% 2000 times of liquid of No. 3 suspending agents of young urea that go out, and the apple spiraea aphid there is the well double effect of controlling, be that apple leaf miner and aphid mix a phase better prevention medicament, can on producing, promote the use of.

2, " 25% EYaLing wetting powder control apple spiraea aphid field control effectiveness test is reported " shows: 25% EYaLing wetting powder is the effective agent of control apple spiraea aphid, 2 days correction preventive effect is up to more than 99% behind its 1500-2000 times of liquid medicine, the field is effectively controlled the phase and can be reached about 15 days, be equivalent to 10% drug effect than 4000 times of liquid of worm quinoline wetting powder, and, can on producing, promote the use of apple safety.

This pesticide sample that my company is sent through " Yantai City Inst. of Agricultural Science, Shandong Prov. " detects the examining report of being provided and shows:

" EYaLing 25WP control apple leaf miner, the report of apple yellow aphid field control effectiveness test " shows: EYaLing 25WP prevents and treats apple leaf miner, the apple yellow aphid preventive effect is remarkable.

The utility model has the advantages that: (1) to apple apple leaf miner, apple yellow aphid have moth, aphid is double controls, the lasting period is long, and tangible preventive and therapeutic effect is arranged, preventive effect is more than 90%.(2) co-toxicity coefficient has obvious synergistic effect greater than 200.(3) toxicity is low.(4) saving of labor, save time, to prevent and treat cost low.
