Description
Technical field
The present invention relates to the pesticides and Chinese medicine mixture composition of a kind of killing subterranean pest-insect and nematode, can prevent crops
Nematode, soil-borne disease, kill subterranean pest-insect, be a kind of low toxic and environment-friendly product.
Background technology
In recent years, as the farming year after year of China crops, multiple crop index are continuously improved, chamber planting area constantly expands
Greatly, returning to the field, chemical pesticide continue largely to use year by year for not decomposed fertilizer and crops stubble, and peasant is with lacking integrated control
The consciousness of lower pest and soil-borne disease, in addition subterranean pest-insect type is various, it is known that up to more than 300 kinds, and it is widely distributed, fit
Ying Xingqiang, concealment are strong, cause subterranean pest-insect occurring and damage to be on the rise, bring about great losses to agricultural production.
Soil is the place that subterranean pest-insect inhabites, breeds and survives.It is an environment complicated and changeable, to subterranean pest-insect
Have a direct impact.The friendship that subterranean pest-insect is collectively formed with bacterium, fungi, nematode, microsporidian and the virus etc. in soil
Wrong complex environment so that the situation of prevention subterranean pest-insect and soil-borne disease is increasingly serious.
Root-knot nematode be China's grain, vegetables, industrial crops one of great pathogen, root-knot nematode becomes north at present
Square vegetable at protected field destructive disease, and southern outdoor cropping fruits and vegetables Major Diseases.It is also maximum to the harm of crops.Root
Root-knot mainly infects crop root, but can also infect the blade of stem tuber, bulb, underground fruit pod and chamber crop sometimes.Ground
Upper part there is not specific symptoms, and when plant harm is serious, leaf is small and yellow, plant are downgraded, or even wilts dead.
Usually not apparent the specializing in of host of root-knot nematode, the plant that can be infected are more than 2000 kinds.National vegetable root
Tie lines worm occurring area is more than 20,000,000 mu, and the vegetables of aggrieved most serious are mainly Solanaceae (such as tomato, eggplant, capsicum), cucurbit
Section (such as various melon) vegetables.
Such as root knot nematode in tobacco occur in Sichuan, Chongqing, Henan, Yunnan, Guangxi, Hunan, Hubei and Shandong it is heavier,
And have the tendency that continuing to aggravate.With the rapid development that tissue culture seedlings of bananas is factory produced, greenhouse nutritive cup seedlings soil zone disease, transplanting
When root-knot nematode is directly brought into crop field, cause banana root knot nematode disease generally to occur.Guangdong, Guangxi, Hainan, Fujian, Yunnan,
The provinces and cities such as Taiwan banana root knot nematode diseases occurs serious, and incidence is typically up to 20%~30%, serious up to 60% or more, the underproduction
40%~60%, seedling stage morbidity then seriously affects outplanting rate.The generation of root-knot nematode infected also with banana bunchy top disease is close simultaneously
Cut phase is closed, and causes to seriously threaten to banana production.
Agriculturally preventing pesticide used in subterranean pest-insect at present mainly has, and carbofuran (Furadan) drips prestige of going out, Nemacur, rice
Le Er etc..Currently without preferable substitution pesticide, this kind of high-toxic pesticide has the shortcomings that：1. by use cost and user
Method limits, and not yet large area uses.2. though a pair nematode prevents preventive effect, do not protrude.3. can polluted source, soil and peripheral ring
Border endangers people and animals larger.4. such pesticide is used for a long time, develop immunity to drugs.
Same vegetable variety is planted in continuous cropping, continuous cropping for many years, is the main reason for root-knot nematode disease occurs.In recent years,
Due to the plantation continuous for many years of crops, then stubble plant growth is suppressed or serious, subterranean pest-insect and soil-borne disease occur for disease
Evil seriously affects the normal growth and yield of crops, causes crop yield low, of poor quality.Because of soil-borne disease and subterranean pest-insect
It infects jointly, the low problem that continuous cropping disease is presented of plant autoimmune function brings about great losses to peasant.With cropping system
Change, subterranean pest-insect endangers trend and aggravates, and prevents and be also increasingly difficult to.
Being more toxic for the pesticide of conventional chemical prevention, endangers the production of pollution-free food, so new technology should be found.
Paecilomyces lilacinus biological pesticide biological control plant pathogeny line insect is the hot spot studied at present, it has been found that can prevent nematodiasis
Biology has fungi, nematode, turbellarian worm, enchytrae, insect, mite class of nematode-trapping etc.；The virus of parasitic nematode, protozoan, bacterium
Deng；It also can be used the extracting solution of plant, control effect also preferable.
For this problem of prevention subterranean pest-insect, generation, development, protecting ecology and the extension of pest resistance to insecticide are avoided or delayed
The service life of conventional pesticide kind, research and development insecticide mixture preparation is one of effective measure.My company selects
The mixtures such as Paecilomyces lilacinus, Avermectin B2, maidenhair, Diacloden, clothianidin and Dipel, for preventing vegetables, cigarette

The Important Natural Enemy of some plant nematodes can parasitize ovum, can also infect larva and female adult, can substantially reduced various crop
The harm of the nemas such as root-knot nematode, cyst nematode, Ditylenchus dipsaci.Paecilomyces lilacinus is Meloidogyne incognita and white cyst
Effective bacterial parasite of line eggs is up to 60%~70% to the percentage of egg parasitism of Meloidogyne incognita.There is prevention to a variety of nematodes
Efficiency, host have root-knot nematode, cyst nematode, golden nematode, golden nematode, even people and animals' bellyworm, are prevention root knots
The most promising biological prevention and control agent of nematode.Paecilomyces lilacinus is Paecilomyces lilacinus and nematode egg capsule to the inhibiting mechanism of root-knot nematode
After contact, in adhesive matrix, biocontrol microorganisms mycelia surrounds entire ovum, and mycelia end is thicker, due to exogenous metabolism object and fungi
The activity of chitinase makes chorion surface layer rupture, and subsequent fungi invades and replaces.Also it can excrete poison and poisoning is risen to nematode
Effect.
Paecilomyces lilacinus microbial inoculum is pure microorganism work spore preparation, has efficient, spectrum, long-acting, safe and pollution-free, nothing
It the features such as residual, can obvious stimulation plant growth.Experiment proof, can not only using Paecilomyces lilacinus microbial inoculum around root system of plant
It is apparent to inhibit nematode infection, and the growth of root system of plant and plant nutrition organ, such as seed dressing can be promoted, cave when field planting
It applies, with growth of seedling there is facilitation to the sprouting of seed, it can be achieved that seedling is complete, Miao Lv, robust seedling, can generally make crop yield
15% or more.
Maidenhair, composite family Tagetes herbaceous plant contain eelworm-killing activity object α-terthienyl and 5- (3-J alkene-
1 alkynyl-α, 2 '-Dithiophenes).Under the action of light, the nematode in soil, the photosensitive molecular of three thiophene is lured to absorb luminous energy,
It is transformed into excitation state from ground state, biomembrane is made to aoxidize, destroys the structure and function of nematode cell membrane, it is dead to finally result in nematode
It dies.
Avermectin B2 is the active constituent of abamectin fermented generation, and main active is avermectin B2a, right
Root-knot nematode, a variety of nematodes such as Ditylenchus dipsaci, parasite have extra high killing activity.
Avermectin B2 is a kind of nerve toxicant, has unique mechanism of action, acts on insect neuron cynapse or god
γ-aminobutyric acid (GABA) system through muscle cynapse promotes the channels C1- that GABA is gated to extend and opens, and a large amount of C1- are poured in
Cause neural membrane potentials hyperpolarization, neu caused to be in holddown, to block nerves impulse conduction and make insect paralysis,
Food refusal, death.Experiments have shown that Avermectin B2 is to cucumber, tomato, watermelon, banana, great Jiang, citrus, sweet potato, soybean, rice, small
The infectivities nematode activity such as root-knot nematode, pratylenchus of the crops such as wheat is very high, and toxicity is low, using more safety and environmental protection, has
Society and economic value well.
