(1) join by above-mentioned, the middle herbaceous plant that screening is good is pulverized separately, and it is standby to cross 80 mesh sieves;

The medicinal powder of also crossing 80 mesh sieves that (2) will crush mixes standby by proportioning;

(3) medicinal powder that crushes is put into high-pressure bottle, add suitable quantity of water, boiling 2 hours, a pressure 1--5 atmospheric pressure, 100 ℃ of temperature;

(4) with well-done medical filtration, the bottling packing is the finished product warehouse-in.

Using method is: soup is diluted 20--50 doubly, be sprayed directly on crops, fruit tree, vegetables blade face, also can be used for stirring kind.

Advantage of the present invention is synthetic by herbaceous plant in multiple, manufacture craft is simple, the raw material abundance is easy to get, cost is low, through for many years the development and repetition test, various insects are had good inhibition and killing action, particularly all can reach green vegetables worm, cotton sandfly worm, aphid, two spotted spider mite and suppress and killing action, total effective rate reaches 95%.The present invention is synthetic by natural plants; so do not contain any poisonous chemical analysis; can be on plant and fruit tree, vegetables after the sprinkling the residual and infiltration of noxious material; and avoided user's poisoning; also protected eater's safety; having avoided the pollution of soil environment and water resource simultaneously, be widely used in rural area, vast city, is a kind of novel nuisanceless environment-friendly insecticide.
