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] Example 1 Preparation of spinosyn and horseradish compound synergistic suspension

[0038] The compound synergistic suspension agent of spinosyn and horseradish of the present invention is composed of spinosyn, horseradish, organic solvent and water, and the mass percentage of each component is: spinosyn 1-30%, horseradish 1- 30%, Tween80 (emulsifier) ​​1-20%, xanthan gum (thickener) 0.1-3%, glycerol (antifreeze) 1-5%, calcium lignosulfonate (dispersant) 0.1-10 % And the balance of water. Prepare according to the following steps:

[0039] First, pulverize the spinosyn powder with an ultrafine pulverizer, and then add the ingredients of spinosyn technical, horseradish and emulsifier into a stirred container, stir for 20-30 minutes, and mix, then emulsify at high speed. In the machine, disperse at a speed of 1000-3000r / min for 20-30min to uniformity. Then add the dispersant, thickener, antifreeze, and defoamer of the ingredients in order to the remaining water under agitati...

Embodiment 2

[0041] Example 2 Preparation of spinosyn and horseradish compound synergistic water dispersible granules

[0042] The compound synergistic water dispersible granules of spinosyn and horseradish of the present invention are composed of spinosyn, horseradish and auxiliary agents, and the mass percentage of each component is: spinosyn 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 according to the following steps:

[0043] Add the effective ingredients spinosyn, horseradish, dispersant, wetting agent, disintegrant and filler into a container with stirring, add a certain amount of water, and mix evenly by stirring. Then the material is pulverized by an ultrafine jet mill, after kneading, granulation, drying, and screening are carried out in a fluidized bed granulation dryer, and various indicators of the product are analyzed through sampling...

Embodiment 3

[0044] Example 3 Preparation and application of spinosyn and horseradish compound synergistic water emulsion

[0045] The compound synergistic water emulsion of spinosyn and horseradish of the present invention is composed of spinosyn, horseradish, organic solvent and water, and the mass percentage of each component is: spinosyn 1-20%, horseradish 1- 20%, ethyl acetate (cosolvent) 0.5-10%, polyglycerol fatty acid ester and polyoxyethylene fatty acid ester (emulsifier) ​​1-10%, silicone oil (defoaming agent) 0.5-2%, xanthan Gum (thickener) 0.1-3%, glycerol (antifreeze) 1-10%, sodium hexametaphosphate (dispersant) 1-10% and the balance water. Prepare according to the following steps:

[0046] Step 1. Prepare spinosyn oil phase and horseradish oil phase

[0047] First, add the ingredient amount of spinosyn technical and cosolvent into a container with stirring, and stir until the spinosyn is completely dissolved. Add the ingredients of horseradish and emulsifier into another stirred ...

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 field of biological pesticides and grain storage, and relates to a compound composition of spinosyn and horseradish, a stored-grain control agent containing the same, and their application in preventing and controlling Entomophthora in stored grain. Background technique [0002] "The warehouse is real, the world is safe." Insect mold is the most important factor threatening the safety of grain storage. The losses caused by stored grain pests and mildew in my country are as high as 20-30 billion yuan every year. At present, due to the long-term single use of phosphine fumigation for the prevention and control of insects in stored grains in my country, a series of problems such as increasing pest resistance, chemical residues, and environmental pollution are caused. Therefore, the development of safe, efficient, environmentally friendly and non-influencing on the quality of stored grain insecticides for biological control has bec...
