Ultralow volume liquid containing spirotetramat

The invention discloses ultralow volume liquid containing spirotetramat, which is prepared by using spirotetramat or a compound of the spirotetramat and an activated ingredient II as an activated ingredient and adding adjuvant and solvent. An activated ingredient B is optional one of etofenprox, efficient cypermethrin, deltamethrin, tolfenpyrad, chlorantraniliprole, flubendiamide, ivermectin, indoxacarb, RH-5849 (1, 2-dibenzoyl-1-tert-butylhydrazine) and tebufenozide. The ultralow volume liquid containing spirotetramat has the advantages of convenience in processing, long-term effect, a target being not easy to resist the pesticide, low environmental pollution, pesticide and water economization, increase of pesticide utilization rate, and can be used for controlling various pests on rice, wheat, vegetables, tobacco plants, tea plants, fruit trees and sugarcanes by means of ultralow volume spray, low volume spray or ultralow volume static spray.

Preparation method of ivermectin sustained-release microspheres

The invention relates to ivermectin sustained-release microspheres used as an animal medicine for animal injection, and a preparation method thereof. The invention belongs to an interdisciplinary field of biomedical polymer materials and controlled release preparations. The invention discloses ivermectin sustained-release microspheres, which are characterized in that: the ivermectin sustained-release microspheres have particle sizes of 0.1 to 10mum, a medicine loading capacity of 20% to 35%, and an entrapment rate of above 80%. The preparation method of the ivermectin sustained-release microspheres comprises steps that: a carrier material and the medicine ivermectin with a mass ratio of 1:1-10 are dissolved in an organic solvent; the solution is processed through supersonic wave or mechanical stirring, such that the solution is emulsified into an oil phase, wherein a volume ratio of oil phase to water phase is 1:5-10; under a temperature of -10 DEG C to 30 DEG C, the oil phase is injected into a water phase disperse medium solution step-by-step; constant-temperature magnetic stirring is carried out with a rotation speed of 400 to 10000rpm, the mixture is sufficiently emulsified, such that an S/O/W type emulsion is obtained; the emulsion is stirred under room temperature for 3 to 4 hours, such that the organic solvent is sufficiently volatilized; the obtained product is centrifuged, washed, collected, and is vacuum-dried with a pressure of 0.01 to 0.04MPa under room temperature for 10 to 12 hours or is lyophilized under a temperature of -0 DEG C to -20 DEG C. With the processes, ivermectin sustained-release microspheres with particle sizes of 0.1 to 10mum are obtained.
