A synergistic type spinosyn suspensions and microsphere preparation

The present invention discloses a synergistic type spinosyn suspensions of microspheres and a preparation method for spinosad and piperonyl butoxide as a core material for the polylactic acid biodegradable material as wall material, manufactured much spinosad synergistic microspheres, and then microspheres spinosyn synergistic wetting dispersants, thickeners magnesium aluminum silicate, ethylene glycol antifreeze, silicone defoamers and water are mixed to prepare the synergistic type spinosad microsphere suspension. The present invention overcomes the deficiencies of the prior art, the prepared potentiated spinosyn suspensions of microspheres can be provided with only low levels of high biological activity, and thus address the active ingredient content is not high microsphere suspension many problems brought on production applications. Wide-enhancing of the present invention spinosyn suspensions of microspheres control spectrum, high efficacy, stability, environmental pollution, long duration, low cost prevention, pollution-free agricultural meet production requirements.
