Embodiment 1

[0017] On May 21, 2011, in the farmland along the highway section of Changjiang Town, with a total area of ​​126 square meters, it was divided into 9 plots, biological fulvic acid glyphosate, common glyphosate and clean water were compared, with two repetitions, and each plot was designed 7 square meters, the drug is 4ml for each plot, spraying at nine o'clock in the morning. Our experimenters made observations after 3, 5, 7, 10, and 15 days. Biological glyphosate fulvic acid began to react two days after spraying, while ordinary glyphosate did not appear phytotoxicity until four days later. And the efficacy of bio-fulvic acid glyphosate is 25% higher than that of ordinary glyphosate water.

Embodiment 2

[0019] On July 8, 2011, a glyphosate spray test was carried out in Xuzhou, Jiangsu. The overall plan is divided into 9 plots, biological glyphosate fulvic acid, common glyphosate and clear water control, set up two repetitions, each plot is designed to be 15 square meters, the drug is 4.5ml per plot, and spraying is carried out at 9 am. Our experimenters made observations after 3, 5, 7, 10, and 15 days. Biological glyphosate fulvic acid began to react two days after spraying, while ordinary glyphosate did not appear phytotoxicity until four days later. And the efficacy of bio-fulvic acid glyphosate is 30% higher than that of ordinary glyphosate water.

Embodiment 3

[0021] On July 29, 2011, a glyphosate spraying test was carried out in the company's flower beds. The overall plan is divided into 9 plots, biological glyphosate fulvic acid, common glyphosate and clear water control, set up two repetitions, each plot is designed to be 10 square meters, the drug is 2.6ml per plot, and spraying is carried out at 9 am. Our experimenters made observations after 3, 5, 7, 10, and 15 days. Biological glyphosate fulvic acid began to react two days after spraying, while ordinary glyphosate did not appear phytotoxicity until four days later. And the efficacy of biological fulvic acid glyphosate is 25% higher than that of ordinary glyphosate water, especially for foxtails and grasses.

Abstract

The invention discloses a 41% glyphosate AS and a preparation method thereof; the glyphosate isopropylamine is added with biological fulvic acid or fulvic acid salts and water; the process comprises the following steps: mixing and stirring 62% glyphosate isopropylamine mother liquor, water, alkyl glucoside for half an hour, adding biological fulvic acid, stirring for 1 hour till the mixture is uniform, filtering the mixture through a 800-mesh filter screen to obtain the finished product. The invention combines fulvic acid substances with glyphosate isopropylamine, can maintain the soil fertility and promote the growth of crops; the invention can reinforce the adhesion and rapid absorptive capacity of plant roots, and especially has obvious effect on physiological diseases caused by trace element deficiency.

Description

technical field [0001] The invention relates to a 41% glyphosate and a preparation method thereof, in particular to a pesticide mainly composed of glyphosate isopropylamine salt and a preparation method thereof. Background technique [0002] Glyphosate herbicide is a destructive (broad-spectrum) pesticide, which can control almost all weeds and has a wide range of uses. However, the herbicide also has certain side effects, which are explained below in conjunction with its mechanism: Glyphosate binds to enolpyruvate shikimate-3-phosphate synthase (EPSPS) and inactivates it, enolpyruvateshikimate-3-phosphate Synthase is a key enzyme in the plant shikimate synthesis pathway and is necessary for the synthesis of aromatic amino acids, including the essential amino acids phenylalanine, tryptophan and tyrosine, as well as downstream products such as plant growth promoters - indole Acetic acid and plant defense compounds - phytoalexins [4]. In reality, glyphosate-resistant (GT) tr...
