Abstract
The invention relates to a herbicide composition for a wheat field. The herbicide composition contains effective components including florasulam, aminopyralid (or salt compounds of aminopyralid) and a phenoxy carboxylic acid herbicide, wherein the phenoxy carboxylic acid herbicide is one selected from 2-methyl-4-chlorophenoxyacetic acid, 2-methyl-4-chlorophenoxyacetic acid sodium salt, 2-methyl-4-chlorophenoxyacetic acid-isooctyl, 2,4-D, 2,4-D butyl ester and 2,4-D isooctyl ester. The herbicide composition disclosed by the invention has a synergistic effect and is remarkably better than each independently-used agent in effect on preventing and removing annual weeds in the wheat field; and by using the herbicide composition, the herbicide controlling spectrum is widened, meanwhile, the dosage is reduced, the generation of herbicide resistance of the weeds is delayed, and the environment pollution is relieved.
Description
Technical field
The invention belongs to technical field of pesticide, being specifically related to a kind of is the Herbicidal combinations of active ingredient with florasulam, chlorine Fampridine acid (or its esters compound), phenoxy carboxylic acid herbicides, is applicable to prevent and kill off wheat paddock especially with the wheat paddock annual weed that shepherd's purse (Capsella bursa-pastoris), geranium wilfordii (Geraniumwilfordii), field thistle (Cirsium setosum), Descurainia sophia (Descurainia sophia) are advantage weeds.
Background technology
Florasulam (florasulam) florasulam is triazolopyrimidine sulfonamides super-high-efficient weed killer herbicide, florasulam is inner-adsorption conduction-type herbicide, weeds complete stool can be conducted to, thus herbicide is thorough, can not recur, efficacy stability at low temperatures, even still stable drug effect can be ensured 2 DEG C time, florasulam broad weed-killing spectrum, the most of broad leaved weed of wheatland can be prevented and kill off, comprise the difficult anti-weeds such as clearvers (Rubiaceae), corn gromwell (Boraginaceae), and have extraordinary inhibitory action to the wartwort (Euphorbiaceae) prevented and kill off the most difficult in wheatland.
Chlorine Fampridine acid (aminopyralid), for picolinic acid class new herbicides, be mainly used in preventing and kill off annual and perennial broad leaved weed, be widely used in mountain region, grassland, the preventing and kill off of planting site and uncultivated area weeds, the acid of chlorine Fampridine is reacted to potassium hydroxide, sodium hydroxide, ammoniacal liquor etc. and can also be obtained corresponding salt.
