Embodiment 1
[0017] Example 1: 40% glufosinate-ammonium water purifier.
[0018] Glufosinate-ammonium 25%, arazine 15%, calcium alkylbenzene sulfonate 10%, nonylphenol polyoxyethylene ether 5%, propylene glycol 5%, and deionized water make up 100%. The 40% glufosinate-ammonium water purifier can be prepared by dissolving and mixing the above-mentioned components in water to form a transparent and homogeneous liquid.
Embodiment 2
[0019] Example 2: 30% glufosinate-ammonium soluble liquid preparation.
[0020] Glufosinate-ammonium 10%, arazine 20%, triethanolamine salt 10%, castor oil polyoxyethylene ether 10%, cyclohexanone 8%, propylene glycol 5%, and deionized water make 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 30% glufosinate-ammonium soluble liquid can be prepared.
Embodiment 3
[0021] Example 3: 60% glufosinate-ammonium·ametrazin soluble granules.
[0022] Glufosinate-ammonium 35%, ametryn 25%, pull open powder BX 10%, alkylbenzene sulfonate calcium salt 10%, sodium bicarbonate 2%, kaolin 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 It can produce 60% glufosinate-ammonium · ametryn soluble granules.

Abstract
The invention discloses a weeding composition containing glufosinate-ammonium and ametryn, which comprises common assistants, glufosinate-ammonium and ametryn, wherein the weight ratio of the glufosinate-ammonium to the ametryn is 90:1-1:50, and the sum of the glufosinate-ammonium and ametryn accounts for 5-85 wt% of the pesticide composition. The pesticide composition is suitable for preventing and removing weed in uncultivated areas, orchards and farmlands, has obviously higher preventing and treating effects than a single agent, lowers the pesticide consumption, and reduces the adverse effect of the pesticide on the ecological environment; and thus, the pesticide composition has important meanings for comprehensive treatment of resistance of weed, and has huge economic benefits and social benefits.
Description
technical field [0001] The invention relates to a pesticide herbicide composition and its application field, in particular to a herbicide composition with glufosinate-ammonium and ametryn 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] Ametryn belongs to the triazine herbicides and can be used before and after emergence. After the plant absorbs ametryn, it conducts upward and concentrates in the top meristem of the plant, inhibiting the electron transfer in the photosynthesis of sensitive plants. Lead to...
