Embodiment 1

[0040] One, the formula proportioning example 1 in table 1, by weight content is as follows:

[0041] Chlorpyrifos 12%

[0042] Iso blast net 18%

[0043] Solvent is Xylene 16%

[0044] Emulsifier 5050PB 9% and D935 2%

[0045] Antifreeze is propylene glycol 8%

[0046] The co-solvent is N,N-two% methylformamide 3%

[0047] The remainder is water 32%

[0048] Second, the preparation process:

[0049] With reference to the technological process in accompanying drawing 1, take quantitative organic solvent by the prepared concentration and add in the there-necked flask with stirring, take quantitative chlorpyrifos, isopyridine and emulsifier, co-solvent respectively, add respectively, stir After dissolving, transfer it to a container with a high-speed shear emulsifier, adjust the speed to 2000-5500r / min, then add a certain amount of antifreeze and water, and emulsify for 10-60 minutes to make the oil phase evenly dispersed in the water phase to become stable water emulsion...

Embodiment 2

[0052] One, the formula proportioning example 2 in table 1, by weight content is as follows:

[0053] Chlorpyrifos 3%

[0054] Isomyza net 1.5%

[0055] The solvent is toluene 25%

[0056] Emulsifier 5050PB 10% and D935 5%

[0057] Antifreeze is ethylene glycol 10%

[0058] Co-solvent is N,N-dimethylformamide 5%

[0059] The remainder is water 39.5%

[0060] Two, preparation method is with embodiment 1, makes water emulsion.

Embodiment 3

[0062] One, the formula proportioning example 3 in table 1, by weight content is as follows:

[0063] Chlorpyrifos 10%

[0064] Iso blast net 15%

[0065] The solvent is mesitylene 20%

[0066] Emulsifier 5050PB 9% and D935 5%

[0067] The antifreeze is polyethylene glycol with a degree of polymerization of 200 7%

[0068] Co-solvent is N, N-dimethylformamide 4%

[0069] The rest is 30% water

[0070] Two, preparation method is the same as embodiment 1, makes water emulsion.

Abstract

The pesticide composite consists of chlorpyrifos 3-55 wt%, isoketazine 1.5-40 wt%, emulsifier 4-15 wt% and C6-C20 hydrocarbon or halohydrocarbon as organic solvent 10-50 wt% and has water as dispersing medium as well as, maybe, antifreezing angent and cosolvent. It has a CTC as high as 355, less organic solvent consumption, relatively high environment compatibility and low cost. It has specificeffect on longitudinal leaf roller of rice, certain effect on cotton tetranychidae, aphid, cabbage worm and other pests as well as preventing effect on sheath and culm blight of rice, banded sclerotial blight of rice and microspheric rhizoctonia disease.

Description

1. Technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with chlorpyrifos as the main active ingredient and its application. 2. Background technology [0002] Chlorpyrifos (English name chlorpyrifos), chemical name O, O-diethyl-O (3,5,6-trichloro-2-pyridyl) phosphorothioate, also known as Lesben (Dow AgroSciences, Inc. Product name), Anminle, Keleshi, etc., were first developed by DOW Chemical Company of the United States in 1965. It is an organophosphorus insecticide and acaricide with high efficiency, broad spectrum and low toxicity. Chlorpyrifos is an extremely broad-spectrum insecticide that can control above-ground and below-ground pests. More than 20 years of application have proved that the use concentration has not increased, and pests have basically no resistance to it. Chlorpyrifos mainly controls pests through three modes of action: contact killing, stomach poisoning and fum...
