Embodiment
The invention provides a kind of Osthole biotic pesticide, comprise 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 biotic pesticide of the present invention can suppress the chitin on insects body wall and fungal cell wall to deposit, thus destroys the body wall structure of insects, can also act on the nervous system of insect simultaneously, makes insect can not eubolism, finally causes it dead.
In order to solve diffusibility when existing Osthole uses as insecticide separately low, to be sprayed on crop easily dry, the easy problem such as decomposition, using Osthole as while primary insecticide, the soybean grease of 3-5 part is added in Osthole, due in soybean grease containing more long-chain saturated or undersaturated fatty acid, belong to reasonable organic solvent, can effectively dissolve and disperse Osthole.The anti-oxidant of Osthole and anti-decomposability can also be improved simultaneously, greatly strengthen the stability of insecticide.
In insecticide, add 6-10 part emulsifier simultaneously, when emulsifier is dispersed in dispersate surperficial, form film or electric double layer, dispersion facies tract can be made to power on lotus, thus effectively stop the droplet of disperse phase to condense mutually, make the emulsion of formation more stable, after being sprayed on crop surface, the phenomenon of condensation can not be produced, ensure that the effect of insecticide.
Owing to the addition of the water-soluble bad composition such as emulsifier and soybean grease in this insecticide, in order to strengthen the immersional wetting of active principle and solvent in insecticide further, therefore in insecticide, wetting agent 2-6 part is added, effectively can either fuse each component, can keep moistening after simultaneously can also ensureing on insecticide spraying to crops, thus can effectively prevent insecticide due to air-dry rapidly and cause inefficacy.
Owing to the addition of the oleophylic such as soybean grease and emulsifier and hydrophobic material in above-mentioned insecticide, also need when insecticide uses to add 10-15 part water as coordinating solvent and regulating concentration, problem simultaneously in order to prevent above-mentioned substance from not easily disperseing in water, dispersant 5-8 part is added in insecticide, for disperseing each component, each component sedimentation and cohesion can also be prevented simultaneously, form stable suspension.
From the above, Osthole biotic pesticide of the present invention is adopted not to be by Osthole and the collocation of other Synergistic fertilizers, but Osthole is added the material of various miscellaneous function, further improve pure Osthole insecticide diffusibility low, be sprayed on crop and easily do, the problem of easy decomposition etc., overcome other biological agricultural chemicals unicity simultaneously, take effect slow shortcoming, to all kinds of aphid, 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.There is during use good Environmental compatibility, a small amount of biopesticide can 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 selects dodecyl benzene sulfonate (such as sodium, potassium, calcium salt, simultaneously these metallic elements can also as the fertilizer of plant growth) or polyoxyethylene oleic acid ester.These two emulsifier that the present invention adopts are except containing except a large amount of hydrophobic emulsification groups, and itself and Osthole do not produce antagonism, and amalgamation is relatively good, effectively can promote effect.
In order to be combined with other components above-mentioned better, wetting agent of the present invention is sodium butylnaphthalenesulfonate or isopropyl naphthalene sulfonate, with the hydrophilic of other and oleophilic substance, all there is good solvation, the infiltration of insecticide can be met further after interpolation, can wetability be kept in making it use, strengthen efficacy window.
The dispersant adopted in the above-mentioned embodiment of the present invention is fatty acid ethylene ether or sorbate APEO, and through learning this test repeatedly, the dispersion effect adopting these two kinds of materials to make dispersant is best.
Further, in the above-described embodiment, the optimum ratio of insecticide of the present invention is Osthole 2 parts, soybean grease 3 parts, emulsifier 7 parts, wetting agent 5 parts, dispersant 6 parts, water is 12 parts.Adopt this ratio, in insecticide, the proportion of each component is relatively more even, and stability, wetability and uniformity are best.After being sprayed onto crops, can have good elastic space with the dew on crops, fog etc., consumption is minimum, effect is also best.
