Problems solved by technology

However, due to the narrow insecticidal spectrum and high volatility of AITC, the agent can only control stored grain insects and molds in a short period of time. The original drug has strong tear-inducing properties and high cost of use, which affects its application.
[0006] So far, there has been no report on the compounding of spinosad and horseradish to form a synergistic composition used as a pesticide for controlling insects and mildew in stored grains

Embodiment 1

[0037] The preparation of embodiment 1 spinosad and horseradish composite synergistic suspension

[0038]The compound synergistic suspension of spinosad and horseradish of the present invention is composed of spinosad, horseradish, organic solvent and water, and the mass percentage of each component is: spinosad 1-30%, horseradish 1- 30%, Tween 80 (emulsifier) ​​1-20%, xanthan gum (thickener) 0.1-3%, glycerol (antifreeze) 1-5%, calcium lignosulfonate (dispersant) 0.1- 10% and the balance water. Prepare as follows:

[0039] First, the spinosad powder is pulverized by an ultrafine pulverizer, and then the ingredients of spinosad, horseradish and emulsifier are added into a stirring container, stirred for 20-30 minutes, and then emulsified under high-speed shearing In the machine, disperse at a speed of 1000-3000r / min for 20-30min until uniform. Then add the dispersant, thickener, antifreeze, and defoamer in the amount of ingredients into the remaining water in turn under stir...

Embodiment 2

[0041] The preparation of embodiment 2 spinosad and horseradish composite synergistic water dispersible granule

[0042] The spinosad and horseradish composite synergistic water-dispersible granule of the present invention is composed of spinosad, horseradish and auxiliary agents, and the mass percentage of each component is: spinosad 1-10%, horseradish 1- 10%, sodium hexametaphosphate (dispersant) 2-10%, sodium lignosulfonate (wetting agent) 1-10%, urea (disintegrant) 1-5%, and diatomaceous earth (filler) balance . Prepare as follows:

[0043] Add active ingredient spinosad, horseradish, dispersant, wetting agent, disintegrant and filler in batching amount into a container with stirring, add a certain amount of water, and mix evenly by stirring. Then, the material is pulverized by an ultra-fine jet mill, and after kneading, it is granulated, dried, and sieved in a fluidized bed granulation dryer, and various indicators of the product are analyzed by sampling. Water-dispers...

Embodiment 3

[0044] Preparation and Application of Example 3 Spinosyn and Horseradish Composite Synergistic Water Emulsion

[0045] The compound synergistic water emulsion of spinosyn and horseradish of the present invention is composed of spinosad, horseradish, organic solvent and water, and the mass percentage of each component is: spinosad 1-20%, horseradish 1- 20%, ethyl acetate (solvent) 0.5-10%, polyglycerol fatty acid ester and polyoxyethylene fatty acid ester (emulsifier) ​​1-10%, silicone oil (defoamer) 0.5-2%, xanthan Glue (thickener) 0.1-3%, glycerol (antifreeze) 1-10%, sodium hexametaphosphate (dispersant) 1-10% and the rest of the water. Prepare as follows:

[0046] Step 1, preparing spinosad oil phase and horseradish oil phase

[0047] Firstly, add the ingredient amount of spinosad original drug and co-solvent into a stirring container, and stir until the spinosad is completely dissolved. Add the ingredients of horseradish and emulsifier in another stirred container, and d...

Abstract

The invention discloses a pleocidin and athomin compounded composition and application thereof.The effective ingredients of the compounded composition comprise pleocidin and athomin.A method in the technical field is adopted, the compounded composition can be prepared into emulsion in water or microemulsion or a suspending agent or wettable powder or water dispersible granules or the like.The pleocidin and athomin compounded composition has an obvious synergistic effect as a protective agent for grain storage, the insect killing toxicity is obviously higher than that of any single agent, the double effects of insect killing and mould preventing are achieved, and the insecticidal spectrum and the mould proof spectrum are wide.

Description

technical field [0001] The invention belongs to the fields of biological pesticides and grain storage, and relates to a compound composition of spinosyn and horseradish, a stored grain control agent containing the compound composition, and their application in preventing and controlling stored grain insect mold. Background technique [0002] "The warehouse is solid, the world is safe." Insects and molds are the most important factor threatening the safety of grain storage. In my country, the annual losses caused by stored grain pests and mildew are as high as 20-30 billion yuan. At present, due to the long-term single use of phosphine fumigation for the control of stored grain insects and molds in my country, a series of problems such as increasing pest resistance, chemical residues, and environmental pollution have been caused. Therefore, the development of safe, efficient, environment-friendly and no impact on the quality of stored grain insect mold biocontrol agents has ...
