Embodiment 1

[0017] Example 1: 38% glufosinate-ammonium-propachlor aqueous solution.

[0018] The following substances are all percentages by weight: glufosinate-ammonium 30%, propachlor 8%, phenethylphenol polyoxyethyl polypropylene ether 8%, nonylphenol polyoxyethylene ether 5%, diethylene glycol 5% , Deionized water makes up 100%. Dissolve and mix the above-mentioned components in water to form a transparent and homogeneous liquid, and then a 38% glufosinate-ammonium-propachlor aqueous solution can be prepared.

Embodiment 2

[0019] Example 2: 40% glufosinate-ammonium-propachlor soluble liquid.

[0020] The following substances are all percentages by weight: glufosinate-ammonium 10%, propachlor 30%, styrene polyoxyethylene ether ammonium sulfate 8%, castor oil polyoxyethylene ether 8%, cyclohexanone 8%, propylene glycol 5% , Deionized water makes up 100%. Stir the above active ingredients and solvent to form a uniform oil phase, then add emulsifier, antifreeze and water to mix into a transparent and homogeneous liquid, and then a 40% glufosinate-ammonium-propachlor soluble liquid can be prepared.

Embodiment 3

[0021] Example 3: 55% glufosinate-ammonium-propachlor soluble granules.

[0022] The following substances are all percentages by weight: glufosinate-ammonium 35%, promethachlor 20%, pull-off powder BX 10%, lignosulfonate 10%, sodium bicarbonate 2%, and kaolin to make up 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrating agent and carrier evenly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving, that is Can produce 55% glufosinate-ammonium-propachlor soluble granules.

Abstract

The invention discloses a herbicidal composition containing glufosinate-ammonium and propachlor, comprising commonly used adjuvants, glufosinate-ammonium and propachlor, and the weight-number ratio of glufosinate-ammonium and propachlor is 10: 1-1:10, the weight percentage of the sum of glufosinate-ammonium and promethachlor in the pesticide composition is 1%-80%. The pesticide composition of the present invention is suitable for preventing and controlling weeds in non-cultivated land, orchards, and farmland. One-time application of pesticides can not only kill some weeds on the ground, but also has a good sealing effect on unearthed weed seeds, saving time, effort, and Reduce the burden on farmers.

Description

technical field [0001] The invention relates to a pesticide herbicide composition and its application field, in particular to a pesticide composition with glufosinate-ammonium and promethachlor as active ingredients, which is mainly used for preventing weeds in non-cultivated land, orchard and farmland. Background technique [0002] Glufosinate-ammonium is an organophosphorus non-selective contact herbicide targeting glutamine synthetase (GS). It is mainly used to control annual or perennial dicotyledonous and gramineous weeds and sedges in orchards, vineyards, non-cultivated land, etc., but it is ineffective for unearthed young shoots and seeds, and it will lose its activity after contacting the soil. [0003] Propisochlor is an amide systemic selective pre-emergence herbicide. It is suitable for dryland crops such as soybean, corn, sunflower, potato, sugar beet and pea to control annual gramineous weeds such as barnyard grass, goosegrass, crabgrass and foxtail, as well as...
