Abstract
The grains fumigating pesticide is compounded with Chinese herbal medicine manchurian rhododendron leaf and pricklyash leaf as well as methanol as assistant. It is used to treat wheat moth, corn weevil and other grains pests, and has high pesticidal effect. Rattus and rabbit experiments show that it has no irritation, low toxicity and high safety.
Description
The present invention relates to a kind of insecticide, particularly a kind of fumigating pesticide that is used for the processing of grain desinsection.
Tradition adopts the method for fumigation Celfume that grain is carried out desinsection and handles.Recently find that Celfume can damage the ozone layer, and carcinogenesis arranged that therefore, most countries or prepare to stop using Celfume.Organophosphorus insecticides such as people are also with dichlorvos, aluminum phosphate and natural instincts material are mixed and made into sustained release agent and are used for the grain desinsection and handle, but organophosphorus insecticide toxicity is bigger, remains in the grain to be detrimental to health.Therefore, people are in low, the safe grain desinsection new technology of research toxicity.
In recent years, Mitsubishi heavy industry company develops a kind of technology of grains such as paddy being carried out the desinsection processing by increase and decrease carbonic acid gas air pressure.This technology has been utilized the principle that decompression suddenly can make object expand under high pressure conditions, and grain is placed in the treatment trough, feeds carbonic acid gas, and carbonic acid gas will be penetrated into the interior and worm's ovum inside of body of adult pest, larva, and penetrates into grain hardly; Then the groove internal gas pressure is elevated to 30 atmospheric pressure, continues decompression suddenly after several minutes.At this moment, nearly all insect all can be dead because of the health swelling fracture, and worm's ovum is also destroyed, and grain is then unaffected substantially.Compare with conventional method, new technology is to environment damage and all less to the harm of human body.But this new technical equipment investment is bigger, and processing cost is higher, also not exclusively is fit to China's national situation at present, and actual applying still had any problem.
It is low to the purpose of this invention is to provide a kind of toxicity, safe grains fumigating pesticide.
Fumigating pesticide of the present invention is to make with Chinese herbal medicine FOLIUM RHODODENDRI MICRANTHI and bunge pricklyash leaf and additive compound, and its medicine is formed and is:
FOLIUM RHODODENDRI MICRANTHI 50-80% bunge pricklyash leaf 5-20%
Ethanol 10-30%
Further the medicine composition is:
FOLIUM RHODODENDRI MICRANTHI 60-70% bunge pricklyash leaf 1-15%
Ethanol 20-30%
Wherein ethanol should use content at ethanol more than 95% or absolute ethyl alcohol.
The manufacture method of above-mentioned fumigating pesticide is: after FOLIUM RHODODENDRI MICRANTHI, bunge pricklyash leaf are dried, mix in proportion, be ground into 8-120 purpose fine powder, add the ethanol of ormal weight, mix and make.
Rhododendron micranthum is the section of Cuculidae plant Xiao Hua cuckoo, isolated volatile oil from FOLIUM RHODODENDRI MICRANTHI, mouse gavaging LD
50=85.5g/kg, " plateau Chinese herbal treatment handbook is described its " bitter, cold in nature, poisonous ".Bunge pricklyash leaf is the leaf of luxuriant growth aromatic plant Chinese prickly ash, and Compendium of Material Medica is put down in writing its " desinsection, foot bath gas and dermatitis rhus ".Two kinds of medicines all have the function of fumigation desinsection, can be used for preventing and treating insects such as gelechiid in the grain, corn weevil.
The purpose that adds ethanol is to help the effectively volatilization of insecticidal constituent in the Chinese herbal medicine, improves insecticidal effect.
Fumigating pesticide of the present invention is carried out toxicity test, rat oral, through skin median lethal dose LD
50All＞and 2150mg/kg, suck median lethal dose LD
50＞4640mg/m
3, all belong to low toxicity, the skin of rabbit and the test of eye irritation fluidity are all shown nonirritant, therefore, fumigating pesticide toxicity of the present invention is low, safe, to the person poultry safety.
The present invention also has easy to use, good disinsection effect, the advantage that the term of validity is long.
Be Application Example of the present invention below.
Embodiment 1:
After the FOLIUM RHODODENDRI MICRANTHI plucked and bunge pricklyash leaf dried, take by weighing FOLIUM RHODODENDRI MICRANTHI 30kg, bunge pricklyash leaf 5kg mixes, be ground into whole energy by 80 purpose fine powders, in fine powder, add the 15kg absolute ethyl alcohol again, mix, make grass green powdery fumigating pesticide, bottling by the dosage of 200g/ bottle packs.
Can preserve 300kg grain for every bottle, use term of validity half a year.
During use, bottleneck sealing is opened, be put in the grain and get final product.
