Abstract
In the present invention ginkgo leaf, ginkgo epicarp and other parts as raw material are prepared to plant pesticide via drying, crushing, solvent extraction, effective component separation and other steps. The said pesticide is in oil emulsion, water emulsion, microemulsion, wettable powder and other forms. It can be used in killing various pests, including homoptera and lepidoptera pests, such as cotton leafworm, rice stem borer, cabbage moth, plant hopper, etc. and has obvious pesticidal effect, high selectivity, low toxicity, low residue, less drug resistance, etc.
Description
Technical field
The present invention relates to the purposes of ginkgo, belong to the pesticide processing field, in particular ginkgo is as the application of vegetable insecticide.
Background technology
Ginkgo Ginkgo biloba L. is a Ginkgoaceae Ginkgo plant, is China's endemic tree, have the title of " living fossil ", has another name called maidenhair tree, Gong Sunshu, dita.Extensively plant various places, more with East China and southwest.Now extensively introduce a fine variety for countries in the world.But the gingko resource of China accounts for about 70% of world's total amount.Ginkgo leaf has value medicinal and aspects such as health care, nutrition, so research is more.When studying as medicine and health products etc., the extraction of active ingredient, product development etc. are quite ripe.But finding no so far with the ginkgo is primary raw material, makes the report of vegetable insecticide as the research of pesticide plant and report so far seldom.Our result of study shows, the extract of ginkgo leaf, exocarp is effective to various pests, comprise Homoptera and lepidopterous insect, reach more than 80%, the preventive effect of plant hopper, leafhopper and aphid is reached more than 90% as preventive effect to prodenia litura, striped rice borer and diamond-back moth.By the method that biologically active is followed the trail of and chemical separation technology combines, isolate active component.The objective of the invention is to the ginkgo is primary raw material, makes the vegetable insecticide of a kind of efficient, low toxicity, low-residual.
Summary of the invention
The new purposes that the purpose of this invention is to provide ginkgo, i.e. new application in vegetable insecticide.
The technical solution adopted for the present invention to solve the technical problems.Ginkgo of the present invention is primary raw material as the application of vegetable insecticide with ginkgo leaf, exocarp etc., after drying, the pulverizing, extracts with different solvents, and measures the insecticidal effect of each extract.Ginkgo leaf, pericarp carry out the active ingredient separation after with alcohol extract, through certain process, can be made into the vegetable insecticide of formulations such as missible oil, aqueous emulsion, microemulsion, wetting powder.
Ginkgo of the present invention is as the application of vegetable insecticide, application is a various pests, comprise Homoptera and lepidopterous insect, reach more than 80%, the preventive effect of plant hopper, leafhopper and aphid is reached more than 90% as preventive effect to prodenia litura, striped rice borer and diamond-back moth.
In order to understand essence of the present invention better, its new purposes in the vegetable insecticide field is described below by test and result.(1), ginkgo biloba crude extract is to the effect of keeping away of refusing to brown planthopper of biologically active 1.1 ginkgo biloba extracts of brown planthopper
The results are shown in Table 1, ginkgo biloba p.e has the stronger effect of keeping away of refusing to brown planthopper, with the rice stem behind the 4mg/ml extract-treated 24h brown planthopper is refused the rate of keeping away up to 92.59%.Refuse the effect of keeping away in time increase and reduce, but behind 96h, still have the higher rate of keeping away of refusing.The rice stem of handling 24h, 48h and 96h refuses to keep away middle concentration (AFC to brown planthopper
50) be respectively 0.57,0.98 and 1.70mg/ml.

1.2 ginkgo biloba extract is refused the effect of keeping away to the interior suction of brown planthopper
The results are shown in Figure 1, ginkgo biloba p.e has stronger interior suction to refuse the effect of keeping away to brown planthopper, and refuses the rate of keeping away and increase along with increasing progressively of concentration.When the concentration of ginkgo biloba p.e is 0.01mg/ml, be 21.67% to the rate of keeping away of refusing of brown planthopper nymph; And when concentration is 10mg/ml, refuses the rate of keeping away and then reach 83.56%, there were significant differences between each concentration.

Ginkgo biloba p.e has action of contace poison hardly to the brown planthopper nymph, and when concentration reached 50mg/ml, the lethality of brown planthopper only had 4%.1.4 small plot experiment
The results are shown in Table 2, in small plot experiment, ginkgo biloba extract still has the higher effect of keeping away of refusing to brown planthopper.After using 0.1% ginkgo biloba p.e, remaining brown planthopper borer population is starkly lower than contrast on the paddy rice, proofreaies and correct and refuses the rate of keeping away all more than 98%.

The result shows that after getting food 5d on the blade of handling, the survival of black peach aphid adult is subjected to than obvious suppression.Under 1.0% the concentration, the survival rate of aphid is 56.67%, and comparison is according to descending about 40%.But a little less than the next influence of low concentration.The life-span of black peach aphid adult all is subjected to suppressing more significantly under different concentration with the farrowing amount simultaneously, black peach aphid life-span and farrowing amount are compared respectively according to having reduced 60.31% and 66.95% under 1.0% concentration, under 0.2% concentration, black peach aphid life-span and farrowing amount are compared respectively according to reducing 25.01% and 50.07%, also are significant difference with contrast.Illustrate that ginkgo biloba extract has certain toxic action to the black peach aphid adult, but a little less than the effect, when concentration was higher, toxic action was comparatively obvious, and concentration is when low, and the insecticidal activity of black peach aphid is mainly shown as the life-span to ginkgo biloba extract and fecundity all is subjected to stronger inhibition.Aspect two of life-span and fecundities, the suffered inhibitory action of black peach aphid fecundity bigger (seeing Table 2).

Along with increasing of concentration, the ginkgo crude extract strengthens gradually to the control action of black peach aphid population.The population quantity of getting the black peach aphid of food on the blade that 1.0% concentration was handled is 24.0 a/leaf, and contrast is 78.1 a/leaf, and only 30.73%, 0.2% concentration for contrast also has certain control action, and the population quantity comparison is according to reducing by 21.79% (see figure 1).

The result shows that ginkgo biloba p.e has stronger food refusal effect, stomach toxicity toxic action and the inhibitory action of growing to black peach aphid.Through extract-treated, can cause the black peach aphid life-span (time-to-live) to shorten, fecundity descends, and causes individual death, first farrowing aphid is especially had tangible lethality, thereby suppress the population growth of black peach aphid effectively.After ginkgo biloba crude extract is mixed with cream preparation, can reach insecticidal effect preferably in the field, the preventive effect that 1000 times dilution preventive effect reaches 89.86%, 2000 times dilution has also reached 77.93%, and the lasting period is about 7d.(3), the ginkgo leaf ethanol extract to the biologically active 3.1 ginkgo leaf ethanol extracts of striped rice borer to the striped rice borer deterrent effect of laying eggs
The results are shown in Table 1.The ethanol extract of ginkgo leaf has the stronger deterrent effect of laying eggs to the striped rice borer adult, and along with the deterrent effect of laying eggs that increases the striped rice borer adult of concentration strengthens gradually.Through soup handled the ovum amount of wild rice stem blade all far below contrast, account for the 16.29-38.24% of contrast ovum amount, concentration 0.125%, ginkgo biloba extract reaches 61.76% to the rate of keeping away of avoiding of striped rice borer, and it avoids the rate of keeping away up to 83.71% under 0.50% the concentration.
