Description
Technical field
The present invention relates to a kind of weed killer herbicide, be specifically related to a kind of corn field herbicide composition.
Background technology
Along with industrialization development with to the demand of feed, China is progressively increasing the demand of corn.2007, China's maize planting area surpassed paddy rice, became the crops of China's cultivated area maximum.China's maize planting geographical distribution is very extensive, east is from Taiwan and coastal provinces, to Xinjiang and Tibet plateau, south is from the Hainan Island of north latitude 18 degree, all there is cultivation in north to the north of the Heihe of north latitude 53 degree, thereby the weeds kind is also very complicated with harm, and grassy weed mainly contains barnyard grass grass, eleusine indica, lady's-grass, green foxtail etc., and broad leaved weed mainly contains kitchen garden, Amaranthus retroflexus, acalypha copperleaf, piemarker, Siberian cocklebur, lamb's-quarters etc. and some sedge weeds such as the rhizome of nutgrass flatsedge etc.It is sym-trinitrobenzene, substituted urea class, amide-type and development in recent years sulfonylurea rapidly that China uses more weed killer herbicide.The weed killer herbicide kind that is used for corn at present China produces only has atrazine, piperazine humulone, alachlor, Acetochlor, isopropyl methoxalamine, propisochlor, trefanocide, 2, kind surplus the 4-D etc. 10, and the cauline leaf inorganic agent is seldom behind the seedling.
Carfentrazoneethyl (have another name called triazolone grass ester, the azoles humulone or the spirit of going out soon, CAS number is 128621-72-7) is that its chemical name is by the triazolineone weed killer herbicide of U.S. FMC Corp. exploitation: (
RS)-2-chloro-3-[2-chlorine]-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4-triazol-1-yl)-4-fluorophenyl] ethyl propionate.Structural formula is as follows:
It is a kind of proporphyrinogen oxidase inhibitor, have active high, easily degraded, weeding fast, be subjected to advantages such as climatic effect is little, dispenser still can keep good effect under low temperature (≤5 ℃) condition.Can prevent and kill off annual broadleaf weed, grassy weed and nutgrass flatsedge.But it is because of mechanism of action restriction (no systemic activity), all make during use whole weeds abundant medicine, invalid to the weeds that grow after the dispenser.It is narrower also to exist the optimum period for applying fertilizer, and the longevity of residure is longer, the shortcoming that safety is relatively poor.
The chemical name of halosulfuronmethyl (have another name called the pyrrole chlorsulfuron, CAS number is 100784-20-1) is: 3-chloro-5-(4,6-dimethoxypyridin-2-base amino carbonyl amino sulfonyl)-1-methylpyrazole-4-carboxylate methyl ester.Structural formula is as follows:
It is a kind of sulfonylurea herbicide, can be used for wheat, corn, paddy rice, Chinese sorghum, cotton, sugarcane, lawn etc. and prevents and kill off broad leaved weed and sedge weed, also begins extensive use in China.But have the highly active while, its application conditions is comparatively harsh, uses the improper poisoning that causes easily.
