Abstract
The invention relates to weeding composition containing foramsulfuron, halosulfuron-methyl and iodosulfuron-methyl-sodium. The active ingredients comprise foramsulfuron, halosulfuron-methyl and iodosulfuron-methyl-sodium in a weight proportion being (0.1-50): (0.1-40): (0.1-20). The weeding composition is suitable for controlling and eliminating annual weed in the corn field, especially for annual dominant weed such as amaranthus retroflexus, cirsium setosum and cyperus rotundus in the corn field. The weeding composition has the synergistic interaction effect, enlarges the weed control spectrum and reduces the weed resistance risk.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations being active ingredient with foramsulfuron, halosulfuronmethyl, iodine metsulfuron-methyl, be mainly applicable to prevent and kill off corn field especially with Amaranthus retroflexus (Amaranthus retroflexus), field thistle (Cirsium setosum), the rhizome of nutgrass flatsedge (Cyperus rotundus L.) for advantage weeds are in corn field annual weed.
Background technology
Foramsulfuron (foramsulfuron), sulfonylurea systemic herbicide, can be weeds cauline leaf and root absorption, conduct in plant corpus subsequently, cause sensitive plant growth retardation, cauline leaf chlorisis, withered gradually, generally death in 20-25 days, but when temperature is lower, needed to some perennial weed the longer time.Dispenser good drug efficacy before 4 leaf phases after bud, when seedling is large, dispenser drug effect declines.This medical instrument has activity of weeding before bud, but activity is comparatively low after bud, can prevent and kill off annual and perennial grassy weed, part broad leaved weed.Test shows, the weeds strong to Drug Sensitivity have And-gather grass, green foxtail, wild oat, Amaranthus retroflexus; The medium weeds of susceptibility have Ben Shi knotweed, rule grass, kitchen garden, Monochoria vaginalis, Siberian cocklebur and piemarker, nutgrass flatsedge; The poor weeds of susceptibility mainly contain lamb's-quarters, black nightshade, Commelina communis, summer cypress and weasel hemp nettle.
Halosulfuronmethyl (halosulfuron-methrl), for sulfonylurea wide spectrum selectivity inner-adsorption conduction-type herbicide, absorbed mainly through root system, also absorb by cauline leaf, shift rapidly in weeds plant body, Developing restraint, weeds are dead gradually, annual broadleaf weed and sedge weed can be prevented and kill off, be applicable to the crop such as corn, paddy rice.
Iodine metsulfuron-methyl (Iodosulfuron-methyl-sodium) is grand also known as methyl iodide sulphur, for sulfonylurea herbicide, be mainly used in preventing and kill off cereal crop field annual broadleaf weed, to cereal crop safety, on succession crop without impact, high to the compatibility safety of environment, ecology.
Foramsulfuron, halosulfuronmethyl, iodine metsulfuron-methyl composite without relevant report.
