Description
Technical field
The invention belongs to pesticide field, relate to a kind of Herbicidal combinations, be specifically related to a kind of sulfur contained quarry grass calmly and Herbicidal combinations and the application thereof of Triclopyr.
Background technology
Current, a problem that can not be ignored is heavily to plant light supporting in the lawn construction, and especially the harm of weeds is on the rise, and makes the lawn changed beyond recognition.Turf weed is not only the harm on lawn and is won honour for, strives fertilizer with the lawn, strives the space, and the effect on desalination lawn, reduces the aesthetic values on lawn.The lawn plant that is injured shows as individual very thin, fragile, cold-resistant, drought-enduring, anti-trample reduction, so that easily degeneration and dead of lawn, even cause the farmland running to weeds.Therefore, management of weeds is crucial in the planting lawn.
The weeds on harm lawn are nothing more than following three classes: the one, and grassy weed, the 2nd, sedge weed, the 3rd, broad leaved weed.In these a few class weeds, grassy weed and sedge weed are referred to as again monocotyledon weed; Broad leaved weeds is called again broadleaf weed.The key that annual gramineous weed is prevented and kill off is prevented and kill off before rudiment, and the weed killer herbicide kind that the bud rear defence removes is few, and must be careful especially when spraying, in case the grass lawn is produced poisoning.Perennial grassy weed is to nourish and generate as main, and the difficulty of preventing and kill off is large, in malignant weed growth in summer animated period, selects and executes or smear the strong high concentration steriland herbicide of interior suction conduction, and is good such as the glyphosate texts.Dispenser period: plant and broadcast the lawn at 4～5 leaf after dates; Sodding the lawn should be in planting 7 days; The Cheng Ping lawn is at green returning of lawn before the phase.The bud pre-treatment of broadleaved herb, general combination is prevented and kill off grassy weed and is carried out simultaneously.
Therefore, select suitable weed killer herbicide, and correctly use these weed killer herbicides just to become to prevent and kill off the key link of these weeds, selective herbicide generally all uses after weeds emerge, it is the first-selection of lawn chemical weeding, often be 2 kinds～3 kinds and unite use, and do not use separately, but herbicide mixture also to be noted its activity of weeding and safety.
Dithiopyr (dithiopy), chemical name: S, S '-dimethyl-2-difluoromethyl-4-isobutyl group-6-5-flumethiazine-3, the 5-dithio formate belongs to picolinic acid class weed killer herbicide, belongs to picolinic acid class weed killer herbicide.Be used for rice field and Kill weeds, to use before 0.06kg (a.i.)/ha bud and to use with (1.5 leaf phases of barnyard grass) behind 0.12kg (a.i.)/ha bud, can prevent and kill off the annual weed such as barnyard grass, Monochoria vaginalis, difformed galingale herb, mexicana, alisma canaliculatum.But can not prevent and kill off firefly Lin, Herba Cyperi Glomerati, Sagittaria pygmaea and wild arrowhead.The impact that the activity of weeding of this weed killer herbicide is not changed by environmental factor, to rice safety, but the lasting period reaches annual gramineous weed and some broad leaved weeds in the front Weeds in Turf of 80d. dithiopyr bud, also can prevent and kill off eleusine indica, chickweed, the root of Beijing euphorbia and other annual pernicious single, double cotyledon weeds.But because the dithiopyr price comparison is expensive, the use cost of unit are is large, and to the anti-heterodyne of part broad leaved weed, therefore, and many and other herbicide mixtures in use.
Triclopyr (triclopyr) has another name called lid and fills with energy; Lid is filled with woods; Chemical name: 3,5,6-three Chloro-2-Pyridyle fluoroacetic acid.A kind of pyridines weed killer herbicide, it is a kind of selectivity inner sucting conduction type herbicide after seedling, it has the activity of plant hormone, simultaneously, respiration, metabolism of nucleic acid to the mitochondria system are inhibited, Triclopyr can be by the blade of plant and root absorption and in vivo fast conduction, accumulate in growing point, make weeds withered, disleave, necrosis occur, final whole strain is dead, greenweed is effectively prevented and kill off the multiple broad leaved weeds such as dayflower, piemarker, knotweed, acalypha copperleaf, lamb's-quarters, Amaranthus retroflexus surely, to lawn safety.But Triclopyr is invalid to grassy weed, and herbicide spectrum is limited, during use many with prevent and kill off the pharmacy mix of grassy weed.
Lawn herbicide is limit by crop safety at present, the herbicide spectrum is also limited, be used alone the weed killer herbicide single dose and can not control completely effectively the generation of turf weed, moreover some weed killer herbicide is because water-soluble large or the lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all easily causes peripheral flowers and crop or rear stubble flowers of dispenser.
Summary of the invention
