Abstract
The invention relates to a botanical pesticide for lepidoptera pests.The botanical pesticide comprises, by mass, 20-30 parts of mulberry latex, 0.2-0.3 part of antiaris toxicaria lesch latex, 1.5-2 parts of nux vomica extracting liquid, 6-10 parts of duchesnea essential oil.The botanical pesticide is prepared in the mode that water is added according to the dilution ratio of 1:(600-800).According to the botanical pesticide, testing and field experiments for toxicity for lepidoptera pests after use alone and mixing of the four raw materials are researched, and the broad-spectrum-pest-killing botanical pesticide capable of effectively preventing pests from generating pesticide resistance is formed through reasonable mixing.
Description
Technical field
The present invention relates to natural insecticide formula technique field, particularly relate to a kind of planting for lepidoptera pest
Thing insecticide.
Background technology
For a long time, due to aborning in order to ensure that agricultural output and quality use chemical insecticide in a large number,
Cause ecological environment is produced immense pressure, and cause some insect to develop immunity to drugs rapidly, if adding further
Big insecticide consumption, thus cause Practice for Pesticide Residue in Agricultural Products amount severe overweight, people and animals, environment are caused huge
Big harm.Therefore, development and utilization has Environmental compatibility and is increasingly subject to the pesticide resource that the mankind are harmless
The favor of various countries.
Botanical pesticide is the insecticides being processed into by the extracting solution of plant or plant, kills with microorganism
Worm agent equally belongs to biological pesticide, and its effective ingredient is naturally occurring, it is easy to degraded, long-pending in ecological environment
Tired toxicity probability is little, has Environmental compatibility.Organic food ever-increasing to demand, pollution-free food have
Guaranteed effect, it is to avoid the negative effect that applied chemistry pesticide causes, and have and make insect be difficult to produce anti-
The property of medicine, does not kill the advantages such as pest natural enemy, is preferable pesticide type.
Lepidoptera includes moth, butterfly two class insecticide.Belong to Pterigota, Holo metabola.The whole world known about 200,000
Kind, China known about more than 8000 plants.This mesh is the 2nd the big mesh being only second to coleoptera in Insecta.Point
Cloth scope is extremely wide, the abundantest with torrid zone kind.The larva of most kinds is caused harm all kinds of cultivated plant,
Bodily form the greater is often eaten most blade or bores moth branch.Bodily form smaller often leaf roll, sew leaf, knot sheath, weave silk
Knot or pierce plant tissue and take food and cause harm.
Summary of the invention
In order to provide a kind of plant insecticide specific to lepidoptera pest, the present invention provides techniques below
Scheme:
A kind of plant insecticide for lepidoptera pest, is made up of the following raw material in terms of mass fraction:
Mulberry latex 20-30 part, Radix aconiti hemsleyani milk 0.2-0.3 part, Semen Strychni extracting solution 1.5-2 part, Herba Duchesneae Indicae
Quintessence oil 6-10 part;Then according to the dilution ratio of 1:600-800 adds water formulated.
There are a kind of special Buchner's bodies ML × 56 in Mulberry latex, it is hypertoxic to lepidopteran insects,
But it is nontoxic to silkworm;Radix aconiti hemsleyani milk is originally as severe toxicity, and its toxicity mainly acts as in blood circulation
With and mainly showing as when entering in insect digestive system be prevented from insect and Drug resistance occur;Semen Strychni
Extracting solution can improve the epidermis sensitivity of insect so that insecticide can faster deeper into infiltrate through insect
The internal effect reaching to kill insect;Herba Duchesneae Indicae quintessence oil is on the one hand as assist infiltration agent, and on the other hand Herba Duchesneae Indicae is smart
Oil has the effect of convergence, can make the branch and leaf healing acceleration gnawed by insect.By rational for above-mentioned 4 kinds of compositions
Compare after Fu Pei individually certain composition insecticidal effect more preferably, take effect faster and can prevent insect from Drug resistance occurring,
Preventing and treating can be truly realized combine.
Further, described Semen Strychni extracting solution uses microwave-assisted leach extraction method, and granularity is 20 mesh, molten
Agent concentration of alcohol is 45%, and pH value is 7.0, and liquid ratio is 8:1, and before microwave, soak time is 40min, micro-
Wave power 300W, microwave irradiation time is 8min.Use this microwave condition can make in Semen Strychni this parasite killing
The different kind organism alkali that agent plays a major role is extracted to greatest extent, and the extraction ratio of total alkaloids is up to 84.35%.
A kind of preparation method of the plant insecticide for lepidoptera pest, weigh in proportion Mulberry latex,
Radix aconiti hemsleyani milk, Semen Strychni extracting solution, Herba Duchesneae Indicae quintessence oil, heat while stirring, persistently overheating to 45 DEG C time,
The warm water adding 600-800 times is made, and described warm water is to be water-cooled to 45 DEG C after boiling.This parasite killing
Dissolubility is optimal at 45 DEG C for 4 kinds of main components of agent, can form the emulsion system of stable chemical nature.
The beneficial effects of the present invention is: for lepidoptera pest, there is good prevention effect, medication 2-3
Major part lepidoptera pest can be killed, after medication 7-8 days, it is possible to kill almost all of squama wing after it
Mesh insect, and can prevent insect from developing immunity to drugs, meanwhile, the insecticide of the present invention is nontoxic to crop itself,
Do not interfere with the growth of crop itself, it is to avoid the negative effect that applied chemistry pesticide causes.
