Description

A kind of anistree chrysomelid method of insecticide and control thereof

Technical field

The present invention relates to Epidemic Disease of Forest prevention and control field, specifically a kind of insecticide formulation and the method for preventing and treating anistree chrysomelid insect pest thereof.

Background technology

Anistree (formal name used at school: Illicium verum), it is a Plants of Illiciaceae Illicium, its dry fruit is one of flavoring of Chinese dishes and south east asia culinary art, be grown in moistening, warm half cloudy environment, be mainly distributed in South China mainland, fruit was plucked in autumn and winter, after dry, be rufous or yellowish-brown, fragrant odour is and sweet, and fresh branches and leaves or ripening fruits can be made into anise oil, is widely used in spices and pharmaceutical industry.Anistree chrysomelid (Oides leucomelaena Weise), has another name called chrysomelid, the anistree leaf beetle of anistree wooden dipper firefly, belongs to the wide ovum Galeruca of coleoptera Chrysomelidae.This worm is with larva, the adult anistree blade of causing harm, the lighter affects tree growth, severe one the old and new's blade is eaten up entirely, cause Illicium verum Forest full wafer woods leaf to be eaten up, cause the octagonal fruit underproduction year after year, even plant is withered, is the natural enemy of anistree producing region maximum, one of key factor of development Illicium verum production success or failure.The chrysomelid pest control means of identification of traditional anise is the agent of water spray painting or sprays with aerosol, because anistree producing region mostly is area, mountain area, the agent of water spray painting need consume a large amount of water, often lack of water and by a large amount of manpower transport of water on mountain, cost is large, not easy to operate, to spray and be subject to mountain area airflow influence large with aerosol, control efficiency is unstable.

Summary of the invention

goal of the invention:

The object of the invention is for the cost existing in prior art greatly, not easy to operate, the unsettled problem of control efficiency, a kind of insecticide formulation is provided, employing talcum powder is inserts, sneak into decis and the white muscardine fungi conidial powder alive of tagging property and make insecticidal dust, the feature with good disinsection effect, cost little, easy to operate, suitable mountain area work also provides the method for utilizing the anistree chrysomelid insect pest of this insecticide control simultaneously.

Technical scheme: a kind of insecticide of the present invention, the component of this insecticide is as follows: 100 kilograms of talcum powder, 10% 800～1200 milliliters of deltamethrin milk oils, every gram containing 0.8～1.2 kilogram of the beauveria bassiana spore powder of the spore amount 10,000,000,000 of living.

The invention also discloses a kind of anistree chrysomelid method of insecticide control of utilizing, the concrete steps of the method are as follows:

(1) every 100 kilograms of talcum powder are added to 800～1200 milliliters of 10% deltamethrin milk oils, then add every gram containing 0.8～1.2 kilogram of the beauveria bassiana spore powder of the spore amount 10,000,000,000 of living, stir, make insecticidal dust;

(2) mid-March to mid-April, anistree chrysomelid larva was caused harm the phase every year, adopted duster that insecticidal dust is evenly sprayed in the Chinese anise being injured and Illicium verum Forest ground.

beneficial effect:

Compared with prior art, its beneficial effect is in the present invention:

(1) by contact pesticide decis insecticidal action, directly kill the insect of anistree chrysomelid and other harm Chinese anise, play the effect of potion Zhiduo County worm, improve the effect of the anistree extermination of disease and insect pest;

(2) infect by white muscardine fungi and infect insect morbidity, indirectly killing anistree chrysomelid and other insect, pre-pest control occurs again, effectively eradicates the generation of insect;

(3) this insecticide have efficiently, the feature of low toxicity, low-residual, to person poultry safety;

(4) easy and simple to handle, save labour, be subject to mountain area airflow influence little, not water, is not subject to the restriction of anistree forest land lack of water.

embodiment

Below in conjunction with the concrete example of implementing, technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to the art embodiment of institute.

Implement place: anistree forest land, that advection branch, Malin field, Bose City Napo County, Guangxi Zhuang Autonomous Region, 100 mu of forest land areas.

The enforcement time: on March 23rd, 2012

Preparation insecticide: 200 kilograms of talcum powder, 10% 2000 milliliters of deltamethrin milk oils, every gram containing 2 kilograms of the beauveria bassiana spore powders of the spore amount 10,000,000,000 of living.

Step: (1) first adds 2000 milliliters of deltamethrin milk oils in 200 kilograms of talc material and stirs, and adds now the beauveria bassiana spore powder of 2 kilograms, stirs, and makes insecticidal dust;

(2) directly the insecticide preparing is directly sprayed at Chinese anise and Illicium verum Forest on the ground with duster, can see Chinese anise chrysomelid insect land one after another death.
