Technical Field

The invention relates to the field of pesticide preparation, in particular to a sugarcane field herbicide containing 2-methyl-4-chloro-isooctyl ester.

Background

The weeds in the sugarcane field are common and various, and the broad-leaf weeds such as purslane, abutilon, cocklebur, black nightshade, spiny sedge, dayflower and the like are mainly used; grassy weeds such as large crabgrass, green bristlegrass, goosegrass herb, bermudagrass grass, and the like; cyperaceae weeds such as Cyperus rotundus L. Weeds compete with crops for water, nutrients, illumination and space, affect the normal growth of crops and even cause serious yield reduction. Chemical weeding is economical, effective and labor-saving, but most of herbicides have limited weed control spectrum and are easy to cause weed resistance after long-term use, and the herbicides with different action mechanisms are mixed, so that the weeding effect and the weed control spectrum can be improved, and the weed resistance can be delayed.

2-methyl-4-chloro-isooctyl ester is a phenoxy acetic acid selective systemic transduction hormone herbicide, can destroy the conduction tissue of dicotyledonous plants, and can interfere the growth and development. 2 methyl 4 chloro isooctyl is ester soluble organic matter, easily permeates the weeds paraffin layer, gets into the weeds inside, can cooperate other herbicidal component to transmit to each part of weeds, has reduced the quantity of medicament. 2 methyl 4 chloro isooctyl ester is used for replacing 2 methyl 4 chloro sodium, so that unnecessary loss caused by precipitation reaction of the latter can be solved, and the weeding activity of the herbicide is better.

Amicarbazone, the english name is amicarbazone, the chemical name is: 4-amino-5-oxo-3-isopropyl-N-tert-butyl-1, 2, 4-triazole-1-carboxamide. The action mechanism is protoporphyrinogen oxidase inhibitor, which is mainly used for preventing and treating part of annual broadleaf and gramineous weeds in corn fields, sugarcane fields and lawns by inhibiting protoporphyrinogen oxidase in the chlorophyll biosynthesis process to cause cell membrane damage and rapidly wither and die leaves

Aiming at the current research situation of the herbicide for the sugarcane field, the invention provides a compound herbicide of 2-methyl-4-chloro-isooctyl ester and amicarbazone, so as to solve the problems existing in the use of the herbicide for the sugarcane field at present.
