41% glyphosate and preparation method thereof

Abstract

The invention discloses 41% glyphosate and a preparation method thereof. According to the invention, biological fulvic acid or a mixture of biological fulvic acid and water, and a nutrient substance potassium fulvate are added to glyphosate isopropylamine. The method comprises technological steps that: a glyphosate isopropylamine mother liquor, water, and alkyl polyglucoside are mixed and stirredfor half an hour; potassium fulvate is added to the mixture, and the mixture is stirred for 1 hour; when the mixture is uniform, the mixture is screened by using a sieve of 800 meshes, such that a finished product is obtained. According to the invention, fulvic acid substances and glyphosate isopropylamine are used in combination, such that other toxins left in soil can be ameliorated. Therefore,fertility of the soil can be maintained, and crop growth can be promoted. The adhesion force and the rapid absorbing capacity of plant roots can be reinforced. Especially, 41% glyphosate provides a substantial effect against physiological diseases caused by the shortage of trace elements.

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...

Embodiment 1

[0018] On April 21, 2011, in the farmland along the highway section of Changjiang Town, a total of 63 square meters, divided into 9 plots, potassium fulvic acid glyphosate, common glyphosate and water control, set two repetitions, each plot design 7 square meters, the drug is 2ml for each plot, spraying at nine o'clock in the morning. Our experimenters observed after 3, 5, 7, 10, and 15 days. Potassium fulvic acid glyphosate began to react two days after the drug was administered, while ordinary glyphosate did not appear phytotoxicity until four days later. And the efficacy of potassium fulvate glyphosate is 20% higher than that of ordinary glyphosate water.

Embodiment 2

[0020] On July 23, 2011, a glyphosate spray test was carried out in Shanxian County, Shandong Province. The overall plan is divided into 9 plots, potassium fulvic acid glyphosate, common glyphosate and clear water control, set up two repetitions, each plot is designed to be 20 square meters, the drug is 6ml per plot, and spraying is carried out at 9 am. Our experimenters observed after 3, 5, 7, 10, and 15 days. Potassium fulvic acid glyphosate began to react two days after the drug was administered, while ordinary glyphosate did not appear phytotoxicity until four days later. And the efficacy of potassium fulvate glyphosate is 20% higher than that of ordinary glyphosate water.

Embodiment 3

[0022] 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, potassium fulvic acid glyphosate, common glyphosate and clear water control, set up two repetitions, each plot is designed to be 5 square meters, the drug is 1.3ml per plot, and spraying is carried out at 9:00 am. Our experimenters observed after 3, 5, 7, 10, and 15 days. Potassium fulvic acid glyphosate began to react two days after the drug was administered, while ordinary glyphosate did not appear phytotoxicity until four days later. Moreover, the efficacy of potassium fulvic acid glyphosate is 20% higher than that of ordinary glyphosate water, especially for foxtail and gramineous.
