Embodiment
The invention provides a kind of Osthole biological insecticides, comprise the each component of following mass parts: Osthole 1-3 part, soybean grease 3-5 part, emulsifier 6-10 part, wetting agent 2-6 part, dispersant 5-8 part, water 10-15 part.
Osthole biological insecticides of the present invention can suppress chitin on insects body wall and fungal cell wall deposition, thereby destroy the body wall structure of insects, can also act on the nervous system of insect simultaneously, make the insect can not eubolism, finally cause its death.
Diffusibility while using as insecticide separately in order to solve existing Osthole is low, be sprayed on crop easily dry, the easy problem such as decomposition, using Osthole in main insecticide, to the soybean grease that adds 3-5 part in Osthole, owing to containing the saturated or undersaturated fatty acid of more long-chain in soybean grease, belong to reasonable organic solvent, can effectively dissolve and disperse Osthole.Can also improve the anti-oxidant and anti-decomposability of Osthole, greatly strengthened the stability of insecticide simultaneously.
In insecticide, add 6-10 part emulsifier simultaneously, when emulsifier is dispersed in dispersate surperficial, form film or electric double layer, can make to disperse the facies tract lotus that powers on, thereby effectively stop the droplet of disperse phase to condense mutually, make the emulsion of formation more stable, after being sprayed on crops surface, can not produce the phenomenon of condensing, guarantee the effect of insecticide.
Owing to having added the water-soluble bad compositions such as emulsifier and soybean grease in this insecticide, immersional wetting for active principle and solvent in further enhancing insecticide, therefore in insecticide, add wetting agent 2-6 part, can either effectively fuse each component, can also guarantee can keep moistening after insecticide spraying is to crops, thereby can effectively prevent that insecticide is because air-dry causing lost efficacy rapidly simultaneously.
The hydrophobic material owing to having added the oleophylics such as soybean grease and emulsifier in above-mentioned insecticide, when being used, insecticide also needs to add 10-15 part water as coordinating solvent and regulating concentration, simultaneously in order to prevent that above-mentioned substance is difficult for the problem of disperseing in water, in insecticide, add dispersant 5-8 part, be used for disperseing each component, can also prevent each component sedimentation and cohesion, form stable suspension simultaneously.
From the above, adopting Osthole biological insecticides of the present invention is not by Osthole and the collocation of other Synergistic fertilizers, but Osthole is added to the material of various miscellaneous functions, further improved pure Osthole insecticide diffusibility low, be sprayed on crop easily dry, the problem of easy decomposition etc., overcome other biological agricultural chemicals unicity simultaneously, slow shortcoming takes effect, to all kinds of aphids, tea geometrid, cabbage caterpillar, corn weevil, lesser grain borer, rice green smut, downy mildew, powdery mildew of cucumber, powdery mildew of strawberry, grape powdery mildew, graw mold of tomato, tea gall etc. have unique control efficiency.During use, there is good Environmental compatibility, a small amount of biopesticide can be brought into play high-effect effect, effect highly significant, and to animal low toxicity, basic noresidue.
Further, in the above-described embodiment, emulsifier of the present invention select dodecyl benzene sulfonate (such as sodium, potassium, calcium salt all can, simultaneously these metallic elements can also be as the fertilizer of plant growth) or polyoxyethylene oleic acid ester.These two emulsifier that the present invention adopts are except containing a large amount of hydrophobic emulsification groups, and itself and Osthole do not produce antagonism, and amalgamation is relatively good, can effectively promote effect.
