Problems solved by technology

However, in the actual use process, it was found that for grasses and other weeds that are difficult to control, the effect of using pure glyphosate preparations or glyphosate-based preparations is not very obvious. Therefore, it is considered to use a variety of raw materials to compound, to improve weed control

Embodiment 1

[0011] Embodiment 1 (concentration is the compound herbicide of 30%)

[0012] 20% by weight of 2-methyl-4-chlorophenoxyacetic acid isopropylamine salt, 10% by weight of glyphosate isopropylamine salt, 20% by weight of emulsifier and the rest of water. The emulsifiers include 1% NPE, 1% AEO, 1% 100#, 1% 300#, 1.5% T, 1.5% 600#+P 2 o 5 - Phosphate salt, 3% Ci-ester. Put 2-methane-4-chlorophenoxyacetic acid isopropylamine salt and glyphosate isopropylamine salt into the blending kettle according to the weight ratio, then add water in the weight ratio and emulsifier in the weight ratio, stir to make it fully and uniformly mix, stir After about 1 hour, it is pumped into the storage tank, and finally the 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide in the storage tank is packed in the automatic liquid filling line.

Embodiment 2

[0013] Embodiment 2 (concentration is the compound herbicide of 20%)

[0014] 15% by weight of 2-methyl-4-chlorophenoxyacetic acid isopropylamine salt, 5% by weight of glyphosate isopropylamine salt, 20% by weight of emulsifier and the rest of water. The emulsifier includes 1% NPE, 1% AEO, 1% 500#, 1% 102#, 1.5% BY (or EL), 1.5% 2000#, 1.5% 1600#, 1.5% NPE+P 2 o 5 - Phosphate salts. Put 2-methane-4-chlorophenoxyacetic acid isopropylamine salt and glyphosate isopropylamine salt into the blending kettle according to the weight ratio, then add water in the weight ratio and emulsifier in the weight ratio, stir to make it fully and uniformly mix, stir After about 1 hour, it is pumped into the storage tank, and finally the 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide in the storage tank is packed in the automatic liquid filling line.

Embodiment 3

[0015] Embodiment 3 (concentration is the compound herbicide of 15%)

[0016] 12% by weight of 2-methyl-4-chlorophenoxyacetic acid isopropylamine salt, 3% by weight of glyphosate isopropylamine salt, 20% by weight of emulsifier and the rest of water. The emulsifier includes 1% of NPE, 1% of 600#, 1% of 700#, 1% of 102#, 3% of BY (or EL), 1.5% of Ci-ester, 1.5% of NPE+P 2 o 5 - Phosphate salts. According to the weight ratio, 2-methyl-4-chlorophenoxyacetic acid isopropylamine salt and glyphosate isopropylamine salt are put into the blending kettle, then add water in weight ratio and emulsifier in weight ratio, stir to make it fully and uniformly mix, stir for 1 After about an hour, it is pumped into the storage tank, and finally the 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide in the storage tank is packed in the automatic liquid filling line.

Abstract

The invention discloses a 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide which is characterized by mainly comprising the components in percentage by weight: 1-20% of 2-methyl-4-chlorophenoxyacetic acid isopropylamine, 1-10% of glyphosate isopropylamine, 1-20% of emulsifier and the balance of water. Due to the adoption of the proportion, the 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide has a remarkable synergistic effect for grassy weeds, has an additive effect for broad leaf weeds such as chandali and can be used as a sterilant herbicide. Compared with the traditional herbicide, the 2-methyl-4-chlorophenoxyacetic acid and glyphosate compound herbicide has the advantages of brand new herbicide formulation, stronger pesticide effect, smaller dosage, good preventing effect, high weed killing speed and strong adaptability.

Description

technical field [0001] The invention relates to a compound herbicide of 2-methyl-4-chlorophenoxyacetic acid and glyphosate, which belongs to the field of pesticide preparations. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any type of plant, but due to these have residual effects. In agricultural production, malignant weeds often use pure glyphosate preparations or glyphosate-based preparations, which mainly inhibit the enolpyruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikime to phenylalanine. The transformation of acid, tyrosine and tryptophan interferes with protein synthesis, leading to plant death. However, in the actual use process, it was found that for grasses and other weeds that are difficult to control, the effect of using pure glyphosate preparations or glyphosate-based ...
