Embodiment 1

[0018] Example 1 1% spinosad aqueous pesticide

[0019] Weigh 1.0g of spinosad, 4g of phenylethylphenol polyoxypropylene polyoxyethylene ether (1602﹟), 4g of phenylethylcumylphenol polyoxyethylene polyoxypropylene ether (1601-Ⅱ#), 3g of polyoxyethylene sorbitan glyceride (Tween), 3g of ethylene glycol, 3g of penetrant, and 82g of tap water were placed in a reaction bottle. Start stirring and ultrasonically disperse for 30 minutes to obtain the product. The product is a transparent liquid, and the spinosad is completely dissolved.

Embodiment 2

[0020] Example 2 2% spinosad aqueous pesticide

[0021] Weigh 2.8g of spinosad, 3g of phenylethylphenol polyoxyethylene polyoxypropylene ether (1601﹟), 2g of phenylethylcumylphenol polyoxypropylene polyoxyethylene ether (1602-Ⅱ﹟), 92.2 g of tap water was placed in a reaction bottle, started stirring and ultrasonically dispersed for 30 minutes to obtain the product. The product is a transparent liquid, and the spinosad is completely dissolved.

Embodiment 3

[0022] Example 3 5% spinosad aqueous pesticide

[0023] Weigh 5.6g of spinosad, 4g of phenylethylphenol polyoxypropylene polyoxyethylene ether (1602#), 2g of phenylethylcumylphenol polyoxyethylene polyoxypropylene ether (1601-Ⅱ#), Alkylsulfonic acid formaldehyde condensate (sopa) 3g, nonylphenol polyoxyethylene ether phosphate (NP-10PT) 3g, tap water 82.4g, in a reaction bottle. Start stirring, and stir at 50°C for 30 minutes to obtain the product. The product is a transparent liquid, and the spinosad is completely dissolved.

Abstract

The invention relates to a pleocidin water formulation pesticide. The technical scheme of the pesticide comprises the following components in percentage by weight: 0.1-30% of pleocidin, 1-25% of surfactant and the balance of water. To resist cold and improve the pesticide effect and the stability of the formulation, 1-10% of antifreeze agent and / or 1-10% of penetrating agent can be added. The surfactant is non-ionic surfactant and / or anionic surfactant. The pleocidin water formulation pesticide is a green and environment-friendly pure water formulation pesticide.

Description

technical field [0001] The invention relates to a pesticide, in particular to a pesticide in water formulation containing spinosad. Background technique [0002] Since the beginning of the 21st century, my country's pesticide industry has developed rapidly. Nearly one million tons of pesticides are applied to various crops every year. It controls the occurrence of various diseases, insects, and weeds, and has made great contributions to successive harvests. However, the large-scale use of pesticides also has its negative effects. For example, more than 10% of grains and more than 20% of fruits and vegetables contain excessive pesticides. For the sake of human health and reducing environmental pollution, the government has ordered to prohibit the use of highly toxic and high residue pesticides, and vigorously develop green pesticides with high efficiency, low toxicity, low residue and environmental friendliness, especially biological pesticides. [0003] At present, the vari...
