Abstract
The invention discloses a weeding composition which comprises effective amount of trifluralin and bensulfuron methyl, wherein the ratio of the two by weight percent is 1: 999-999: 1, the active ingredients are the trifluralin and the bensulfuron methyl, and the two are mixed and compounded, thereby realizing the synergistic effect, increasing the weeding complementarity of the two and making up for the insufficiencies during the single use. On the one hand, the weeding composition is a composite weeding agent which can reduce the total amount of the applied active ingredients under the premise of ensuring the same weeding effect and have the excellent control effect for dominant populations of vicious weeds and big weeds; on the other hand, the weeding composition can achieve the purpose of controlling both broadleaf weeds and grass weeds by being applied in transplanted rice fields after mixing, thereby playing the effects of increasing yield and increasing effect.
Description
Technical field
The invention belongs to agriculture weeding chemicals technical field, relate in particular to a kind of compound weed killer herbicide that is applicable to the rice field weeding.
Background technology
The chemical name of trefanocide (trifluralin) is: 2, and 6-dinitro-N, N-di-4-5-trifluoromethylaniline.It is to pass in the process of soil layer absorbed by the weed seed germinating growth.Mainly absorbed by the hypocotyl of young shoot of gramineous plants and broad leaved plant, cotyledon and young root also can absorb, but stem after emerging and leaf can not absorb.The classical symptom that causes phyto toxicity is to suppress growth, and the tip of a root and plumular axis histocyte volume significantly expand.Plant cell after being injured stops division, and apical meristem cell diminishes, and is thick and flat, and the cell in the cortical parenchyma increases, the cell wall thickening.Because the vacuole in the cell increases, make cell forfeiture polarity, produce deformity, present the rhizome of " gooseneck boom " shape.After trefanocide is manured into soil, decompose disappearance gradually owing to volatilization, photodissociation, microorganism and chemical action, wherein volatilization and photolysis are the principal elements of decomposing.The loss of executing in initial several hours of the trefanocide of soil watch is the fastest, and moist and high temperature can be accelerated its decomposition rate.
The chemical name of bensulfuron-methyl (bensulfuron-methyl) is: α-[(4, the amino carbonyl amino of 6-dimethoxypyridin-α-yl)] the sulfonyl methyl } methyl benzoate.It is a selectivity inner sucting conduction type weed killer herbicide, active ingredient can be in water diffusion rapidly, transfer to each one of weeds for weeds root and blade absorb, the biosynthesis of hindered aminoacid, lysine, isoleucine stops the division and the growth of cell.The susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the growth of leaf portion, hinders root growth and necrosis, and it is harmless inertia chemicals that active ingredient enters the interior metabolism rapidly of paddy rice body, to rice safety.
Trefanocide, two kinds of weed killer herbicides of bensulfuron-methyl generally are to use separately respectively preventing and kill off on the paddy field weed in the existing technology, and range of application has certain limitation, and effect is general.
Summary of the invention
