Embodiment

[0025] Embodiment: prepare 1.1% abamectin · azadirachtin suspension concentrate

[0026] 1. Take raw materials by weight percentage:

[0027] Abamectin 0.9%

[0028] Azadirachtin 0.2%

[0029] Nonylphenol polyoxyethylene ether (NP-9) (wetting and dispersing agent) 8%

[0030] Propylene glycol (alcohol antifreeze) 2%

[0031] Xanthan gum (thickener) 0.5%

[0032] Silicone defoamer (SAG612) 1%

[0033] Water (filler) 87.9%

[0034] Two, prepare according to the following steps:

[0035] 1. Weigh avermectin, azadirachtin, nonylphenol polyoxyethylene ether (NP-9) (wetting and dispersing agent), propylene glycol (alcohol antifreeze agent) and part of water according to the above ratio and mix well , into a sand mill for grinding.

[0036] 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 to the grinding material according to the above ratio. Keep grinding.

Abstract

The invention provides a living insecticide suspending agent and a production method thereof, relating to the technical field of living insecticide composition production. The living insecticide suspending agent comprises the following components in percentage by the total weight of the living insecticide suspending agent: 0.1-5 percent of abamectin, 0.1-5 percent of nimbin, 4.05-34 percent of addition agent and 56-95.75 percent of water, wherein the addition agent comprises the following components in percentage by the total weight of the living insecticide suspending agent: 1-15 percent of wetting dispersant, 2-6 percent of alcohol anti-freeze agent, 1-10 percent of thickening agent and 0.05-3 percent of silicone antifoam agent. The invention has stable chemical property and obvious synergy, shows obvious synergy and complementation actions for preventing objects, can delay drug resistant generation and achieves the purposes of increasing production and income in agriculture.

Description

technical field [0001] The invention relates to the technical field of biopesticide composition production. 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 harm to the production of vegetables and flower seedlings. In recent years, although the state has ordered to prohibit the use of highly toxic pesticides on vegetables and flower seedlings, there a...
