Abstract
The present invention relates to a green nuisance-free pesticide and its preparation method. It is characterized by that it is composed of mixed 78-98% of extract of whole plant of pueraria peduncularis and 1-22% of white sugar. The fresh or dried whole plant of pueraria peduncularis is socked, then pulped, pressed for 3-4 time to make juice, filtered and the filtrate is stood still to remove starch, then concentrated so as to obtain the extract of pueraria peduncularis. It can be used for killing various injurious insects of crops, and can obtain good control effect.
Description
Technical field
The present invention relates to technical field of pesticide, specifically green nuisance free pesticide and preparation method thereof.
Background technology
Existing pesticide variety is many, but is chemosynthesis mostly.Though insecticidal effect is better, unsatisfactory is residue of pesticide, and people and animals' health is had harmful effect.
Summary of the invention
The purpose of this invention is to provide a kind of pure plant extract preparation, to the person poultry harmless, green nuisance free pesticide that insecticidal effect is outstanding and preparation method thereof.
Technical scheme of the present invention is: with bitter Pueraria lobota [pueraia.Peduncularis (Berth.) Grad.] herb extract 78～98%, white sugar 1～22% mixes and gets.
The preparation method of above-mentioned green nuisance free pesticide is by poly-carrying out of following step:
1) behind the aquatic foods product or dry product immersion with bitter Ge Quancao, making beating is squeezed the juice 3～4 times repeatedly, filters, and filtrate is left standstill except that desizing, and it is standby to get bitter Pueraria lobota extract after concentrating;
2) with 1) after the bitter Pueraria lobota extract 78～98% of gained and white sugar 1～22% mixes, add 0.1～0.5% preservative and obtain green nuisance free pesticide.
The filter residue that bitter Pueraria lobota prepares behind the extract is used for insect preservative paper raw material and fertile as farming.
Green nuisance free pesticide of the present invention can also be produced by the following method: the velvet-like hammer out thing of bitter Ge Quancao is dried, break into powder, cross the above sieve series of 60 orders and become pulvis, bitter kudzuvine root starch agent with 10～20% makes and applies the underground dual-purpose agricultural chemicals of fertile medicine with after fertilizer such as calcareous fertilisers or fertiliser containing magnesium or phosphate fertilizer or potash fertilizer or composite fertilizer mix.
Green nuisance free pesticide of the present invention can kill underground black worm, and (daytime in the ground, evening is on stem leaves of plants, be commonly called as cutworm), grub, earthworm, leech in the water, little red worm and the invisible worm of naked eyes, cabbage caterpillar on the plant, aphid and plant powdery mildew, rust, downy mildew and mite class (two spotted spider mite, rust wall wind, coccid) etc. are all had better prevention effect and killing effect all have killing action for the insect of the seedling that eats in the ground, any seedbed.Its desinsection worm spectrum broad again because plant itself has alkalescence, easily holds and separates, thus can be not residual on plant, can not destroy soil structure, can not pollute beneficial insect and environment.
After preparing by certain dose and water when agricultural chemicals of the present invention uses, be spilled on the base of leaf of plant, by tag, stomach kills and the action kill insect of food refusal.
Below be the insecticidal test of agricultural chemicals of the present invention:
1, seeks aforesaid insect, after finding the worm source, spray insecticide on the base of leaf of nibbling in the worm source again, observed once, the insect food refusal will occur every 2 hours, dry moving uneasiness, through 2～24 hours, the worm that has began death, and what death was the fastest is maggot and water leech, the all death in 24 hours of little red worm in the water, the longest death time of other worm is 72 hours.
2, put agricultural chemicals in the lavatory of having grown maggot, half an hour, maggot will be more active, through observation after a while, finds that maggot is dead, and death time one is well matched to be 2～24 hours, makes the eyes of maggot blind, loses food and death.
3, on the dish leaf, spray insecticide for the cabbage caterpillar food, find cabbage caterpillar death.
4, to some insects such as mosquito, fly eradications, the death with the pulvis sootiness.
5,, can prevent and treat plant powdery mildew, rust, downy mildew and mite class with this pesticide spraying plant.
6, apply the tuberous root plant with the dual-purpose agricultural chemicals of fertile medicine of the present invention, plant looks healthy and strong, and tuberous root does not have sting.
