Abstract

The invention provides a low-toxicity and high-efficiency insecticide for silk cocoons and silks in a warehouse, which is characterized by being prepared by mixing four effective components, namely high-efficiency cypermethrin, permethrin, dichlorvos and trichlorphon, with a nonionic surfactant and a synergist, wherein the low-toxicity pesticide effect is over 90 percent, the silk cocoon untying performance is hardly influenced, and the warehouse insecticidal test effect is excellent. Based on the broad spectrum of the invention, the pesticide can also be used for killing pests and pests of other agricultural and sideline products and grain warehouses.

Description

Low toxicity, efficient silk cocoon, silk warehouse insecticide
The present invention relates to a kind of insecticide, particularly low toxicity, efficient silk cocoon, silk warehouse insecticide.
According to statistics, the annual production of China's silk cocoon in recent years reaches 500,000 tons approximately, accounts for the No. 1 in the world.The silk cocoon place of production spreads all over provinces such as the Guangdong, Guangxi, Zhejiang, Jiangsu, Jiangxi, Sichuan, Yunnan, Fujian of China.Silk cocoon and silk often suffer the infringement of stored grain insects.Insect mainly showed as the gluttony silk, gnaws through cocoon layer or eats silkworm chrysalis causing harm of silk cocoon.Not only separated an achievement decline by the silk cocoon that insect was caused harm, and make cocoon of fine quality become mashed cocoon down, caused serious economy loss to Silk Mill.Identification and analysis according to investigations, the Cocoon Warehouse insect mainly contains hook grain leather moth, red flour beetle, ostomatid, rice weevil etc.Up to the present, when silk cocoon, the generation insect pest of silk warehouse, just adopt some agricultural chemicals simply, as acephatemet, hexachlorcyclohexane powder etc., these agricultural chemicals not only toxicity are big, people and animals are had serious harm, and insecticidal effect is not so good, it is relatively poor especially harm silk cocoon the most serious red flour beetle to be killed effect, some also can reduce silk cocoon and separate an achievement, as makes silk jaundice etc.
The objective of the invention is the insect at silk cocoon, silk warehouse, a kind of low toxicity, wide spectrum, insecticide efficiently are provided, name of product is insecticide ICW-98.
The object of the present invention is achieved like this:
A kind of low toxicity, efficient silk cocoon, silk warehouse insecticide, its feature is being light yellow liquid, cooperates by effective ingredient A, B, C, D and assistant agent E, F to form, wherein:
A, beta-cypermethrin (High effect Cypermethrin) claim efficient cis-, trans-cypermethrin again, molecular formula C 22H 19Cl 2NO 3, molecular weight 416.30
B, permethrin (Permethrin), molecular formula C 21H 20Cl 2NO 3, molecular weight 319.30
C, dichlorvos (DDV), molecular formula C 4H 7Cl 2O 4, molecular weight 220.87
D, chlorophos, molecular formula C 4H 8Cl 3O 4P, molecular weight 257.32
E, Butacide (piperonyl butoxide), molecular formula C 19H 30O 5, molecular weight 338.43
F, non-ionic surface active agent AE09 or TX10
Recipe ratio is:
A:1-10%;B:1-10%;C:0.5-5%;D:0.5-5%;E:1-5%;F:2%
The total content of effective ingredient is 8-18%, and solvent is ketone, aromatic hydrocarbons or alcohols.
About 0.901 (25 ℃) of-described insecticide proportion, boiling point 140-143 ℃, 31 ℃ of flash-points are to light, thermally-stabilised.
-described insecticide can any ratio mix with water, becomes milky white liquid after the mixing.
The LD of-described insecticide 50Be 1250mg/kg,, guinea pig skin do not had obvious stimulation for the low toxicity level insecticide, non-stimulated to the rabbit eyes, when diluting 100 times, LC 50Be 10000mg/kg.
-described insecticide is in dispenser after 7 days, to the LC of red flour beetle worm 50Be 10.64 μ g/ml, to the LC of hook grain leather moth 50Be 99.22 μ g/ml, to the LC of ostomatid worm 50Be 22.28 μ g/ml, to the LC of yellow mealworm 50Be 46.59 μ g/ml.
Below by embodiment, the invention will be further described:
The insecticide ICW-98 of preparation 10%: get A, B, each 25 gram of C, D, after adding 50 ℃ of-80 ℃ of dissolvings of a small amount of dimethylbenzene heating, with non-ionic surface active agent AE0920 gram and Butacide 20 grams, adding ad pond om with solvent xylene after stirring is 1000 grams, after stirring evenly, be the light yellow missible oil of 10%ICW-98 insecticide.
Carry out desinsection in order to following method:
1, stoste spray-on process: with 10%ICW-98, be sprayed at outside the cocoon bag with agroatomizer, every 1000M3 space consumption 1kg sealed door and window 2-7 days then;
2, fumigating system: the ICW-98 with 10%, stoste hangs over the small fan fore blow after soaking cotton, allows medicine gasify, sealing door and window 2-7 days;
3, spray behind the thin up: with the ICW-98 of stoste 10%, spray behind 100 times of the thin ups, consumption is every 1000M 31kg, the sealing door and window is about 10 days.
Beneficial effect of the present invention is the LC to cocoon storehouse insect 50Reach 99-10 μ g/ml, to ticklish insect red flour beetle, LC 50Reach 10.64 μ g/ml, killing rate all is higher than 90%, and silk cocoon is separated almost not influence of an achievement, and anthelminthic test effect in bin is good.Because broad spectrum activity of the present invention is used for silk cocoon so this product is removed, outside the silk warehouse insecticide, the desinsection that also can be used for other agricultural byproducts warehouses and grain depot is removed the evil.
