Embodiment 1

[0027] Example 1 4% nano spinosad parent powder containing solid lipids

[0028] The content of spinosad is 40 g / kg

[0029] Capric acid content is 785 g / kg

[0030] Polyvinyl alcohol content of 165 g / kg

[0031] Dissolve 41.5 grams of 97% spinosad and 785 grams of capric acid in 100 grams of chloroform, then mix with 2200 grams of 7.5% polyvinyl alcohol aqueous solution, and mix the mixture evenly by stirring or shaking or high shear It is emulsified, then micronized by ultrasonic waves to make it into 100-500 nanometer particles, stirred for another 2 hours, and finally freeze-dried to obtain solid lipid nano-type spinosad mother powder.

Embodiment 2

[0033] 8% solid lipid nano spinosad parent powder

[0034] The content of spinosad is 80 g / kg

[0035] Capric acid content is 760 g / kg

[0036] Polyvinyl alcohol content of 160 g / kg

[0037]Dissolve 82.5 grams of 97% spinosad and 760 grams of capric acid in 200 grams of chloroform, then mix with 2000 grams of 8% polyvinyl alcohol aqueous solution, and mix the mixture evenly by stirring or shaking or high shear To the emulsified state, then use ultrasonic micronization to make it into 100-500 nanometer particles, stir for 3.5 hours, and then freeze-dry to prepare.

Embodiment 3

[0039] 12% solid lipid nano spinosad parent powder

[0040] The content of spinosad is 120 g / kg

[0041] The content of capric acid is 700 g / kg

[0042] Polyvinyl alcohol content of 180 g / kg

[0043] Dissolve 124 grams of 97% spinosad and 700 grams of capric acid in 300 grams of chloroform, then mix with 2000 grams of 9% polyvinyl alcohol aqueous solution, and mix the mixture evenly by stirring or shaking or high shear to emulsified state, and then micronized by ultrasonic to make it into 100-500 nanometer particles, stirred for 5 hours and then freeze-dried to prepare.

[0044] 2. Composition preparation and bioassay effect

[0045] The pesticide active ingredients used in the following examples are all calculated according to 100% purity unless otherwise specified. In actual operation, the actual purity of the original drug used is converted, and the difference is adjusted with filler or water.

Abstract

The invention applies to the technical field of pesticide preparations, provides a solid lipid nano spinosad, and also provides a preparation method of the solid lipid nano spinosad and application of the solid lipid nano spinosad on pesticide preparations. Compared with a compound preparation prepared by directly taking nano spinosad raw pesticide as the raw material, the pesticide preparation of the solid lipid nano spinosad has enhanced cold and hot storage chemical stability, reduced photolysis rate, prolonged efficacy period, reduced dosage and obviously improved insecticidal effect.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a solid lipid nano spinosad, a preparation method thereof and an application in pesticide preparations. Background technique [0002] Spinosyn, also known as spinosad (Spinosad), is a macrolide pollution-free biopesticide extracted from the fermentation broth of Saccharopolyspora spinosa. [0003] Spinosad has rapid contact and stomach poisoning effects on pests, has a strong penetrating effect on leaves, can kill pests under the epidermis, has a long residual effect, and has a certain ovicidal effect on some pests. No systemic effect. It can effectively control pests of Lepidoptera, Diptera and Thysanoptera, and can also control some pests in Coleoptera and Orthoptera that eat leaves in large quantities. It is effective against sucking pests and mites. The control effect is poor. [0004] Its mechanism of action is considered to be the effector of t...
