Problems solved by technology

It is very sensitive to grass seedlings, the resistance increases from the 4-leaf stage, and the sensitivity increases at the young panicle differentiation stage. Therefore, it is difficult to solve many grass weeds
[0007] Sodium 2M-4Cl3 has poor effect when used alone as a total herbicide
However, in the actual use process, firstly, it is not easy to control the mixed dose, and secondly, it is mixed according to the doses of glyphosate isopropylamine salt and 2-methyl-4-chloride sodium salt alone, and the cost is relatively high, so it is difficult to popularize and use
[0008] Some products, considering the above problems, the solution is to use glyphosate (glyphosate) and 2-methyl-4-chloride sodium salt to make a solid mixture, which has received a certain effect. However, due to the glyphosate (glyphosate) The herbicidal effect is poorer than that of glyphosate isopropylamine salt. In addition, the cost of making a solid mixture is higher than that of a liquid mixture. In comparison, the liquid mixture of glyphosate isopropylamine salt and 2-methyl-4-chlorisopropylamine salt Has obvious effect advantages and cost advantages

Embodiment 1

[0020] Embodiment 1: each component is by weight percentage:

[0021] Glyphosate Isopropylamine Salt 34%

[0022] Dimethyltetrachloroisopropylamine salt 6.5%

[0023] Alkyl Polyglucoside 10%

[0024] Ethylene glycol 10%

[0025] water balance

[0026] Glyphosate, dimethyltetrachloride, water, and isopropylamine are dissolved into salts, added alkyl polyglucosides, and then ethylene glycol, and the remainder is mixed with water to form an aqueous solution containing 40.5% of the active ingredient. The herbicidal effects are shown in Table 1 ( Thai fire in the table is the total herbicide of the present invention). Among them, 46% glyphosate·dimethyl soluble powder is a solid dosage form mixture made of glyphosate and dimethyl tetrachloride sodium salt. It can be seen from Table 1 that under the same or close active ingredient dosage conditions, Taihuo’s weed control The effect is higher than that of the mixture of solid glyphosa...

Abstract

A sterilant composite herbicide with broad spectrum is proportionally prepared from glyphosate-isopropylamine salt, MCPA-isopropylamine salt, and surfactant.

Description

technical field [0001] The invention belongs to chemical pesticides, in particular to a herbicidal composition. Background technique [0002] The molecular formula of glyphosate-isopropylammonium is C 6 h 17 N 2 o 5 P, the chemical name is N-(phosphonic acid methyl) glycine isopropylamine salt, and its structural formula is: [0003] [0004] The molecular formula of agroxone-isopropylammonium is C 12 h 18 ClNO 3 , the chemical name is 2-methyl-4-chlorophenoxyacetic acid isopropylamine salt, and its structural formula is: [0005] [0006] Glyphosate is a systemic broad-spectrum herbicide, which can control almost all annual or perennial weeds, but it is less sensitive to some weeds, and it needs to increase the dose to improve the control effect. For some weeds, even if the increase Use dosage, also can not receive good preventive effect, and medication cost improves greatly. The commonly used 13% 2M4Cl sodium salt solution in the market has good control effe...
