Embodiment 1

[0008] A kind of herbicide, it is made of the raw material of following percentage by weight:

[0009] Raw material %

[0010] N-(phosphonomethyl)glycine 5

[0011] 1,1-Dimethyl-4,4’-bipyridine cation 8

[0012] 2-[[N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)

[0013] -Methyl N-methylcarbamoyl]sulfamoyl]benzoate 43

[0014] 3-Isopropyl-2,1,3-benzothiadiazinone-(4)-2,2-dihydride 44 is mixed to give a herbicide. The control effect on vicious weeds in the lawn such as sedge weeds, spinach, water peanuts and other broad-leaved weeds reaches 92%.

[0016] Raw material %

[0017] N-(phosphonomethyl)glycine 2

[0018] 1,1-Dimethyl-4,4’-bipyridine cation 8

[0019] 2-[[N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)

[0020] -Methyl N-methylcarbamoyl]sulfamoyl]benzoate 44

[0021] 3-Isopropyl-2,1,3-benzothiadiazinone-(4)-2,2-dihydride 46 is mixed to give a herbicide. The control effect on vicious weeds in the lawn such as sedge weeds, reeds, spinach, water peanuts, ground millet and other broad-leaved weeds can reach 90%.

Embodiment 3

[0023] Raw material %

[0024] N-(phosphonomethyl)glycine 4

[0025] 1,1-Dimethyl-4,4’-bipyridine cation 8

[0026] 2-[[N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)

[0027] -Methyl N-methylcarbamoyl]sulfamoyl]benzoate 38

[0028] 3-Isopropyl-2,1,3-benzothiadiazinone-(4)-2,2-dihydrogenate 50 is mixed to give a herbicide. The control effect on broad-leaved weeds such as sedge weeds, spinach, water peanuts, ground millet and other broad-leaved weeds in the lawn can reach 94%.

Abstract

The invention discloses a herbicide comprising N-(phosphono methyl) glycine, 1,1-dimethyl-4,4'-bipyridylium ion, 2-[[-(4-methoxyl-6-methyl-1,3,5-trigine-2-yl)-N-methylammonocarbonyl] sulphamoyl] methyl benzoate, 3-isopropyl-2,1,3-benzothiadiazine-(4)-2,2-dihydride.

Description

technical field [0001] The invention relates to a herbicide which is suitable for weeding grass lawns. Background technique [0002] The chemical control technology of lawn weeds. At present, there are a large number of reports abroad on the use of different types of herbicides to control weeds on different types of lawns. In my country, the chemical control technology of lawn weeds is still limited to a few farmland herbicides with limited herbicidal spectrum. above. How to solve the weed control of lawn has been a major problem in improving the quality of lawn in my country. For vicious weeds in the lawn, such as sedge weeds, reeds, spinach, water peanuts, ground millet, etc., glyphosate can be used to control them, but the actual operation is difficult. In gramineous turf, different dosages of Ping'an No. 1 have good effects on Cyperaceae weeds and malignant weeds such as spinach, water peanut, and ground millet. Shaporon has special effects on Cyp...
