Abstract

The invention relates to a botanical medicine for preventing and treating aphids of crops. The raw material of the botanical medicine is a Lepidium apetalum and Polygonum glabrum extract liquid, and the extract liquid contains an antiseptic. Rhizomes and leaves of Lepidium apetalum and Polygonum glabrum are adopted as raw materials and are juiced to obtain the extract liquid, the extract liquid is diluted with water, and the diluted extract liquid is sprayed on crops in order to realize a prevention effect when no aphids exist in the crops and realize a very good treatment effect when the aphids exist in the crops; a field test result shows that the prevention and treatment effect reaches 98% or above; the extract liquid can prevent and treat the aphids, and also can obviously prevent and treat thrips, red spiders and other piercing and sucking pests; and Lepidium apetalum and Polygonum glabrum are wild vegetables and can be eaten, so drug residual and environmental pollution problems do not appear in the practical use process, thereby harms of pests are reduced, and the yield increases by 5-8%.

Description

A kind of method using the extract for preventing and treating aphid of pepper grass and polygonum flaccidum

Technical field

The invention belongs to crops control of aphids technical field, especially a kind of method using the extract for preventing and treating aphid of pepper grass and polygonum flaccidum.

Background technology

Aphid, also known as aphid, aphid etc., belongs to Homoptera Aphidiadae more, is the insect of sucking mouth parts, is often clustered in the positions such as blade, tender stem, bud, terminal bud, and thorn inhales juice, makes leaf-shrinkage, curling, lopsided, causes the even whole strain of die back dead time serious.Aphid secretion honeydew also can bring out sooty mould, spread disease the harm such as viral disease.Aphid body is little and soft, belly has tubular protrusion, sucking plant juice, because the fertility of aphid is very strong, female aphid one is born and can gives birth to soon, within 1 year, can breed 10 ~ 30 generations, generation overlap phenomenon is serious, after aphid make inroads on crop, growth rate reduction, generation tikka, yellowing, depauperation, leaf roll, output reduction, quality degradation can be caused, withered and dead, and aphid can also between crops transmitted virus, cause the further disease of crops to occur.

In actual production, people are in order to the anti-harm eliminated aphis, the integrated control of general employing number of ways, comprise: eliminate the aphid of Wintering Period, the new crops introduced be rigid in checking up, prune residual flower deadwood in time, choose there is insect pest variety of crops, chemicals deinsectization, the rational deployment of carrying out field and cleaning to reduce aphid source, interval lays silver grey film bar, sets up the yellow plate, the insect-sticking plate that are coated with machine oil, plant to drive the methods such as aphid plant and prevent and treat.

In aforesaid way, medicine deinsectization is Initiative defence, and other is auxiliary methods, but a large amount of chemical agent that uses is prevented and treated, and the high amount of drug in farming object can be caused to remain, and control efficiency is not fine.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, the medicine based on herbs of environmental protection, noresidue, a kind of crops control of aphids that control efficiency is good is provided.

The technical scheme that the present invention takes is:

A medicine based on herbs for crops control of aphids, is characterized in that: its raw material is the extract liquid of pepper grass and polygonum flaccidum.

Further, described extract comprises preservative, adds the washing powder of 0.1% during use, opens up effect to increase.

Another object of the present invention is to provide a kind of preparation method of medicine based on herbs of crops control of aphids, it is characterized in that: comprise the following steps:

(1) pepper grass and polygonum flaccidum are gathered together with root, stem and leaf, impurity elimination, clean after for subsequent use;

(2) step product is (1) added in cracker and squeeze the juice;

(3) filtered by the solidliquid mixture after squeezing the juice, namely filtering residue makes extract.And, add preservative after described filtering residue, store for future use.

A kind of pepper grass and polygonum flaccidum squeeze the juice the application of extract in crops control of aphids should to put prevention first.

Another object of the present invention is to provide a kind of using method of medicine based on herbs of crops control of aphids, it is characterized in that: comprise the following steps:

(1) extract is mixed with water, then add the washing powder of 0.1%, be prepared into spray;

(2), when preventing eliminating aphis, choose the sunny date, spraying is carried out 1 ~ 2 time to complete stool;

(3), time as prevention aphid, choose the sunny date, spraying is carried out 1 time to complete stool.

Another object of the present invention is to provide a kind of pepper grass and the application of polygonum flaccidum extract in crops control of aphids.

Advantage of the present invention and good effect are:

In the present invention, with pepper grass and polygonum flaccidum together with root, stem and leaf for raw material, by acquisition extract of squeezing the juice, then by the spraying of laggard for extract dilute with water row crop, crop can play the effect of prevention when there is not aphid, good preventive and therapeutic effect can be played during crop generation aphid, test through practical application, prevent and treat efficiency and reach more than 98%, the extract liquid of this pepper grass and polygonum flaccidum, except can preventing eliminating aphis, also obvious preventive effect is had to other sucking insect pest, as thrips, two spotted spider mite etc., and pepper grass and polygonum flaccidum are wild vegetable, edible, so the problem of medicament residue can not be produced in actual use, because decrease the harm of insect, and have the effect of increasing production of 5-8%.
