Embodiment 1

[0025] The configuration method of thickening composition 1 is as follows: put 12 grams of ammonium pyrrolidinedithiocarbamate and 180 grams of surfactant A1 into a 1 kg reactor, then pump in 808 grams of water, start stirring, and heat up to 45°C. Stir for 20 minutes until the solid is completely dissolved, then add 20 g of ammonium chloride, and stir for 20 minutes to achieve a uniform system to obtain thickening composition 1.

[0026] Wherein the structural formula of surfactant A1 is as follows:

[0027]

Embodiment 2

[0029] The configuration method of thickening composition 2 is as follows: put 25 grams of ammonium pyrrolidine dithiocarbamate, 350 grams of surfactant A2 and 200 grams of surfactant B1 into a 1 kg reactor, then pump in 425 grams of water, and start Stir, heat up to 45°C, stir for 20 minutes until the solids are completely dissolved, then add 20 g of ammonium sulfate, stir for 20 minutes until a homogeneous system is obtained, and thickening composition 2 is obtained.

[0030] Wherein the structural formula of surfactant A2 is as follows:

[0031]

[0032] The structural formula of surfactant B1 is as follows:

[0033]

Embodiment 3

[0035] (1) Composition and properties of 18.5% glufosinate-ammonium sodium dimethyltetrachloride aqueous solution

[0036] The 18.5% glufosinate-ammonium dimethyltetrachloride aqueous solution consists of the following components according to the mass percentage:

[0037]

[0038] The properties of 18.5% glufosinate-ammonium dimethyltetrachloride sodium solution are as follows:

[0039]

[0040] Herbicidal efficiency (the total usage of glufosinate-ammonium and sodium dimethyltetrachloride is 200g / ha): 92.1% after 15 days of application; 96.9% after 30 days of application.

[0041] (2) Control agent and performance

[0042] Control drug 1: Compared with the 18.5% glufosinate-ammonium-dimethyltetrachloride aqueous solution in the title (1) of this example, the only difference is that it does not contain thickening composition 1. The viscosity (25°C, rotational viscosity) of the control drug 1 was 12-15 cp.s. Herbicidal efficiency (the total usage of glufosinate-ammoniu...

Abstract

The invention provides a thickening composition for glufosinate and Chipton, and preparation and application thereof, and relates to the field of pesticide chemistry. The thickening composition is prepared from the following components in percentage by weight: 1%-3% of pyrrolidine ammonium dithiocarbamate, 15%-55% of a surfactant, 1%-5% of salt and the balance of water, wherein the surfactant is one or two of (A) and (B). A preparation method of the thickening composition comprises the steps that the water is added into a formula amount of the pyrrolidine ammonium dithiocarbamate and the surfactant, heating is conducted to 40-50 DEG C, and stirring is conducted till solid is dissolved; and a formula amount of the salt is added, the mixture is stirred into a homogeneous system, and the thickening composition is obtained. The thickening composition is specially used for water agents of the glufosinate and the Chipton, adhesion of medical liquid on the leaf surface can be improved, the medicament loss caused by mutual collision and friction of plant leaves due to rain washing and wind blowing is reduced, the using effect is improved, and the preparation method is simple and efficient.

Description

technical field [0001] The invention relates to the field of pesticide chemistry, in particular to a thickening composition for glufosinate-ammonium and dimethyltetrachloride and its preparation and application. Background technique [0002] Glufosinate-ammonium is an organophosphorus-based broad-spectrum herbicide for stem and leaf treatment developed by the former German company Agrefort. Its target is glutamine synthetase. After spraying glufosinate-ammonium for 3 to 5 days, the rate of plant carbon dioxide fixation drops rapidly. , The leaves of the plant appear yellow and necrotic symptoms. Glufosinate-ammonium has the characteristics of high activity, good absorption, broad herbicidal spectrum, low toxicity, and good environmental compatibility. It is another herbicide with excellent performance after glyphosate. [0003] Mixed use of herbicides has indeed played a very significant role in controlling weeds in crop fields. With the advent of genetically modified crops...
