Problems solved by technology

[0008] More importantly, most of emamectin benzoate and indoxacarb on the market are mainly in the form of emulsifiable concentrates, which not only has high product cost and poor drug efficacy, but also causes serious environmental problems during the use of the products. Pollution and excessive waste of resources

Embodiment

[0026] Embodiment: Preparation of 20% emamectin benzoate · indoxacarb suspension

[0027] 1. Take raw materials by weight percentage:

[0028] Emamectin Benzoate 4%

[0029] Indoxacarb 16%

[0030] Nonylphenol ethoxylates (NP-9) (wetting and dispersing additive) 8%

[0031] Propylene glycol (alcohol antifreeze) 2%

[0032] Xanthan gum (thickener) 0.5%

[0033] Silicone defoamer (SAG612) 1%

[0034] Water (filler) 68.5%

[0035] Two, prepare according to the following steps:

[0036] 1. Weigh emamectin benzoate, indoxacarb, nonylphenol polyoxyethylene ether (NP-9) (wetting and dispersing agent), propylene glycol (alcohol antifreeze) according to the above ratio Mix well with some water and transfer to a sand mill for grinding.

[0037] 2. Mix and dissolve xanthan gum (thickener) and water at a ratio of 1:50. Mix silicone defoamer (SAG612) with filler water evenly, and add the amount according to the above ratio to the material being ground. Keep grinding.

Abstract

The invention discloses an insecticidal suspending agent with synergism and a production method thereof, relating to the technical field of the production of the insecticidal suspending agent compound with synergism. The production method comprises the following steps: evenly and fully mixing emamectin benzoate, Indoxacarb, wetting dispersant, cryoprotectant and parts of water; grinding in a sand mill; mixing and dissolving thickener and water at the ratio of 1:50; fully and evenly mixing organic silicon defoaming agent and water; adding the mixture at the above ratio into a grinded material, and continuing to grind; in the grinding process, adding the defoaming agent, and continuing to grind; and finally, discharging. The emamectin benzoate and the Indoxacarb are combined to be adopted in the insecticidal suspending agent, the insecticidal suspending agent has the advantages of stable chemical property and obvious synergism, shows obvious synergism and complementation on a prevention and treating object and can alleviate insecticide resistance.

Description

technical field [0001] The invention relates to the technical field of production of an insecticide suspension composition with synergistic effect, in particular to a preparation method of an insecticide suspension compound compounded with a synergistic chemical pesticide and an antibiotic pesticide. Background technique [0002] In recent years, due to the extensive use of various pesticides, the resistance of agricultural pests has become higher and higher. For example, rice planthoppers, rice stem borers, rice stem borers, and rice leaf rollers are the main pests of rice in my country. In the Yangtze River Basin, rice region is particularly serious. It will cause a large number of dead hearts in the tillering stage, and in addition to causing white ears in the later stage of rice growth, it will also cause a large number of insect damage to the plants, making them lodging in patches. Another example is that vegetable and flower seedling pests are an important cause of har...
