Embodiment 1

[0033] The combination herbicide containing γ-polyglutamic acid was prepared according to the following steps.

[0034] Weigh 1% γ-polyglutamic acid, 5% quizalofop-p-ethyl, 1% imazethapyr, 1% fomesafen, 5% clomazone, 5% lignosulfonate, 1% Warm-60#, 0.5% benzoic acid, 0.5% silicone, 0.2% urea, and deionized water were added to 100% by weight. The above-mentioned raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to obtain a combination of 1% γ-polyglutamic acid and 12% quizalofop, imazethapyr, fomesafen and clomazone. suspending agent.

Embodiment 2

[0036] The combination herbicide containing γ-polyglutamic acid was prepared according to the following steps.

[0037] Weigh 5% γ-polyglutamic acid, 5% quizalofop-p-ethyl, 5% imazethapyr, 5% fomesafen, 5% clomazone, 5% lignosulfonate, 1% Warm-60#, 0.5% benzoic acid, 0.5% silicone, 0.2% urea, soybean oil were added to 100% by weight. The above-mentioned raw materials are mixed, dispersed at high speed for 30 minutes, and then sanded with a sand mill to obtain a combination of 5% γ-polyglutamic acid and 20% quizalofop, imazethapyr, fomesafen and clomazone. Disperse oil suspension.

Embodiment 3

[0039] The combination herbicide containing γ-polyglutamic acid was prepared according to the following steps.

[0040] Weigh 0.5% γ-polyglutamic acid, 12% quizalofop-p-ethyl, 8% imazethapyr, 1% fomesafen, 9% clomazone, 5% lignosulfonate, 1% Warm-60#, 5% ethyl acetate, 0.5% benzoic acid, 0.5% silicone, 0.2% urea, 1% acetic anhydride, and deionized water were added to 100% by weight.

[0041] Operation steps: (1) after completely dissolving quizalofop-p-ethyl, imazamox, fomesafen and clomazone in the above-mentioned raw materials with the solvent, add an emulsifier and mix them uniformly; (2) mix γ-polyglutamic acid and other auxiliaries; (3) put the uniformly mixed material obtained in step (1) into the material in step (2), disperse by high-speed shearing for 30 min, and grind with a sand mill to obtain 5% γ-polyglutamic acid and 30% suspoemulsion of a combination of quizalofop-p-ethyl, imazethapyr, fomesafen and clomazone.

Abstract

The invention discloses a combined herbicide containing gamma-polyglutamic acid. The combined herbicide is composed of 5-25% of quizalofop-p-ethyl, 5-15% of clomazone, 0.2-6% of fomesafen, 1-12% of imazethapyr, 0.05-5% of gamma-polyglutamic acid and the balance of auxiliaries, and is mainly used for preventing and treating various weeds including gramineous weeds, broadleaf weeds and cyperaceae weeds. The gamma-polyglutamic acid in the combined herbicide containing gamma-polyglutamic acid can fully chelate various active components and is attached to surfaces of plants, so that effectiveness of the active components is enhanced. Meanwhile, based on green degradability of the gamma-polyglutamic acid, flora is easily enriched around the plants, and decomposition of residual pesticides in soil is accelerated, so that the half-life period of the pesticides is reduced.

Description

technical field [0001] The invention is applied to the field of pesticide chemistry, in particular to a combined herbicide containing γ-polyglutamic acid and its application in agricultural control. Background technique [0002] Chemical pesticides are an important guarantee for a bumper harvest in modern agriculture, among which herbicides are the largest component of pesticide production and use. Although the long-term, large-scale and extensive use of herbicides has promoted the high yield of food, it has also caused serious harm to farmland and the surrounding ecological environment, which seriously threatens human health and life safety. It has attracted widespread attention. In recent years, the direction of pesticide development is to reflect high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", namely (1) high safety, which requires not only low toxicity, low residue, but also no pollution; (2) high b...
