Abstract

The invention discloses a low-foam low-quantity glufosinate-ammonium and glyphosate surfactant. The surfactant comprises the following components in percentage by weight: 10-30% of ammonium oxide, 10-30% of the surfactant, 1%-20% of dispersing agent is, 1%-20% of wetting agent, 0.1%-10% of the penetrant0.1%-10% of pH regulator and the balance of deionized water, wherein the ammonium oxide is a combination of one or more of lauramidopropyl dimethyl ammonium oxide, cocamidopropylamine oxide, dodecyl dimethyl amine oxide, tetradecyl dimethyl amine oxide, hexadecyl dimethyl amine oxide, dodecyl dihydroxyethyl amine oxide, tetradecyl dihydroxyethyl amine oxide, octadecyl dihydroxyethyl amine oxide and octadecanamide propyl amine oxide.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a low-foaming and low-volume glufosinate-ammonium and glyphosate surfactant and a preparation process thereof. Background technique [0002] Glyphosate is the most widely used herbicide in the world. It is non-flammable, non-explosive, and stable at room temperature. It is a non-selective and non-residual herbicide. Glufosinate-ammonium is a broad-spectrum contact herbicide with weak systemic effect. The herbicide has the characteristics of high efficiency, low toxicity and easy degradation. Due to the difficulty of synthesis, the market price of glufosinate-ammonium is relatively high. These two herbicides are quite different, especially in their distinct mechanisms of action. Glufosinate-ammonium is a glutamine synthetase (GS) inhibitor, which kills weeds by inhibiting this enzyme; unlike glyphosate that kills roots, glufosinate-ammonium kills leaves first, and...
