Description

A kind of macleaya cordata plant powder pesticide

Technical field:

The invention belongs to insecticide, relate in particular to a kind of insecticidal dust agricultural chemicals with the natural plants macleaya cordata.

Background technology

The agricultural chemicals that is used to prevent and treat diseases and pests of agronomic crop at present mostly is a chemicals.Second edition in " Chinese patent newspaper " on June 2nd, 1993 " pesticide industry development Overview and patent situation " one literary composition is introduced: nineteen ninety China's Pesticidal products account for the second place of the world, produce 156 kinds of pesticide species, 59 kinds in its insecticide, 9 kinds of miticides, 3 kinds of fumigant, 7 kinds of rodenticides, 39 kinds in bactericide, 33 kinds of weed killer herbicides, 6 kinds of plant growth regulator.These agricultural chemicals overwhelming majority belong to chemicals.As chemicals such as Methomyl, decis, efficient chlorine nitrogen chrysanthemum ester, nuvacron, Rogor, phoxims, these chemicals make disease have pesticide resistance for a long time, when spraying insecticide, the concentration of agricultural chemicals rises year by year, bring serious environment pollution thereupon, particularly too much spray chemical pesticide residual vegetable problem, caused people's common concern.According to United Nations Environment Programme's statistics, the whole world has 2,000,000 people that acute pesticide poisoning takes place every year, and wherein 40,000 people die.

In view of the shortcoming that chemical pesticide exists, numerous scientific workers begin one's study, and extraction composition effectively alive prepares insecticide from plant.As U.S. a company from tropical plants---the margosa seed provides a kind of toxin to make insecticide, can carry out effectively preventing to little white fly and other insect more than hundred kinds, but this raw material sources are subjected to very big restriction, yield poorly, as the insecticide of non-state Dalmatian chrysanthemum exploitation, because of the soil utilize uneconomical, yield poorly, plantation has been abandoned in the places of production such as Japan, the barren mountain planting in present non-state, output is restricted." a kind of wettable plant insecticide pulvis " (Chinese patent application number 00122074.8) is though select some natural plants for use, as Thunder God rise, radicant such as kuh-seng, southern snake are risen, but these plant growing drug effects need 3-5, resource has been subjected to certain restriction equally, gives to produce to develop and has brought influence.

Summary of the invention:

The purpose of this invention is to provide that a kind of raw material is easy to get, free of contamination macleaya cordata plant powder pesticide.

Macleaya cordata pulvis of the present invention, the percentage by weight of each component is composed as follows:

Humic acid 20-40% is sweet by 2-10%

Macleaya cordata 20-30% Radix Glycyrrhizae 10-15%

Anemone Vitifolia 3-15% short-pedicel aconite root 1-5%

Cortex periplocae 5-10% girald daphne bark 5-10%

Kuh-seng 5-15% sodium lignin sulfonate 1-5%

Poison fly grass 2-10% Octachlorodipropyl Ether 1-3%

Lilac daphne 2-10% cycloheptaamylose 1-3%

Potassium dihydrogen phosphate 1-5%

Preparation method of the present invention carries out the natural plants in the above-mentioned prescription selected, rejecting is damaged by worms, and is spoiled, rotten plant, be crushed to the 60-100 order respectively, by above-mentioned prescription each component is added in the stainless steel still, add entry again and make the material in the still become humidity, be warmed up to 40-60 ℃ then, agitating heating 3-5 hour, take out the back oven dry, be crushed to the 300-450 order, make product.

Chinese herbal medicine insecticidal dust of the present invention is mainly used in corps leaf surface and sprays, seed dressing and soil treatment.

With 800 times of plant insecticide pulvis water dilutions of the present invention, can be used for foliage spray, can prevent and treat various crops such as cotton, melon dish, fruit tree, tealeaves, rape, wheat aphid, mythimna separata, worm, cabbage caterpillar, select the bridge worm, inhale slurry worm, two spotted spider mite etc. strong killing action is arranged, virus, the germ to crop has remarkable prevention effect simultaneously.

Vegetable insecticide of the present invention is used for crops seed dressing and soil treatment, can prevent and treat insect pest in soil effectively, soil insects such as cutworm, Qi teacher, mole cricket worm, wireworm, green onion, garlic, leek root maggot, and can underground laying eggs powerful killing action be arranged to various insect pests, utilize insecticidal dust of the present invention, belong to the biofermentation preparation, can change soil structure, and can play the effect that increases fertilizer.

The present invention has following advantage:

(1) high efficiency.After special process is handled, promptly there is desinsection to render a service, there is fertilising to render a service again, can compete water and spray, but ground is mixed and spilt again.

(2) broad spectrum activity.Can prevent and treat various crop such as cotton, melon dish, fruit tree, tealeaves, wheat, rape aphid, mythimna separata, cabbage caterpillar, select bridge worm, two spotted spider mite etc. that strong killing action is arranged.And the insects that lay eggs such as underground worm such as the cutworm of soil worm, grub, mole cricket worm, wireworm, green onion garlic, leek root maggot there is killing action.

(3) hypotoxicity.Can desinsection evil, can honest and cleanly apply fertilizer again, nontoxic to people and animals, crops are not stayed residual hazard, produces pollution-freely, be the good approach that develops pollution-free food.

(4) plant origin is extensive, is easy to get, and can satisfy requirements of large-scale production.
