Background technology
Penoxsuam, English name penoxsulam, chemical name is: 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) triazole-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN).Be broad spectrum activity translocated herbicide, medicine, via cauline leaf, young shoot and Root Absorption, conducts to meristematic tissue by xylem and phloem, suppresses plant strain growth, makes growing point chlorosis, and the rear 7 ~ 14d terminal bud of process reddens, necrosis, and within 2 ~ 4 weeks, plant is dead.Effectively can prevent and kill off grassy weed barnyard grass, moleplant seed and annual sedge weed, and effective to numerous broad leaved weed, and the lasting period is long.Meanwhile, it also can prevent and kill off anti-bensulfuron-methyl weeds in rice field, and has residual activity to many broad-leaveds and sedge weed and barnyard grass etc., is the kind that herbicide spectrum in current herbicide for rice field is the widest.Be applicable to the direct-sowing dry field of paddy rice, direct-sowing rice, rice seedling bed and rice transplanting, rice transplanting cultivation field.Direct-sowing dry Tian Yuya is front or after pouring water, direct-sowing rice is applied in early days after seedling; Rice transplanting cultivation then 5 ~ 7d dispenser after rice transplanting.Insecticide-applying way can adopt spraying or mix soil process.Lasting period reaches 30 ~ 60d, a drug energy basic controlling full season Weed infestation.
Cyhalofop-butyl, English name cyhalofop-butyl, chemical name is (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate.Cyhalofop-butyl belongs to aryloxyphenoxypropionic class weed killer herbicide, has Uptake and translocation effect, has tight security to paddy rice.By blade and the leaf sheath absorption of plant corpus, phloem conducts, and accumulates the meristem zone in plant corpus, resist acetyl-CoA carboxylase (ACCase), fatty acid is synthesized and stops, the growth division of cell can not normally be carried out, membranous system etc., containing fat structural deterioration, finally cause Plant death.Be absorbed into weeds Mortality Ratio from cyhalofop-butyl comparatively slow, generally need 1 ~ 3 week.
Benthiocarb, English name thiobencarb, has another name called benthiocarb, weed eradication pellet, Benthiocarb, except field green bristlegrass, chemical name is: S-[(4-chlorphenyl) methyl] diethyl thiocarbamate.Benthiocarb is carbamates selectivity inner sucting conduction type soil processing herbicide, can be absorbed by the root of weeds and young shoot, and particularly young shoot is transferred in plant corpus after absorbing, and has very strong inhibitory action to growing point.Benthiocarb hinders α-amylase and protein synthesis, also has strong inhibition effect to the mitosis of plant cell, thus causes the weeds at the weed seed of sprouting and the initial stage of sprouting withered.The speed of barnyard grass Assimilation and conductivity benthiocarb is faster than paddy rice, and the speed of degradation in vivo benthiocarb is slower than paddy rice, and this forms optionally physiological foundation.This type of weed killer herbicide can rapidly by adsorption by soil, and the leaching thus with moisture is little, is generally distributed in soil layer 2 centimeters.The suction-operated of soil decreases the loss caused by evaporation and photodissociation.Half life period in soil, being 2 ~ 3 weeks under ventilation good condition, is then 6 ~ August under anaerobic condition.By soil microbial degradation, by the dechlorination benthiocarb that edaphon is formed under anaerobic condition, can suppress paddy growth consumingly.
A kind of weed killer herbicide of the single use of paddy field, the generation of control paddy field weed that can not be fully effective, if consumption is excessive, easily causes residual hazard to this season crop or succession crop.Penoxsuam, cyhalofop-butyl and benthiocarb are all not identical in chemical classes with the mechanism of action, widely different on water prevention weeds in paddy field.By literature search, the relevant report of penoxsuam, cyhalofop-butyl and benthiocarb ternary built is not yet found that there is at present.
Inventor through the screening of a large amount of formula indoors and field control effectiveness test, find penoxsuam, cyhalofop-butyl and benthiocarb to carry out within the specific limits composite after, have paddy field weed and close and weeding double effects; Speed of action is fast, to the preventive effect of barnyard grass and moleplant seed comparatively penoxsuam and cyhalofop-butyl mixture weeding speed fast; Comparatively penoxsuam and cyhalofop-butyl mixture, add benthiocarb, to barnyard grass and moleplant seed synergistic effect remarkable.The composite expansion control of weeds spectrum of three, reduces use cost, delaying drug resistance, high to crop safety.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, synergistic effect is remarkable, and herbicidal effect is good, and control of weeds spectrum expands, and drug cost is low, energy delaying drug resistance, and the ternary weeding composition to rice safety.
Another object of the present invention is to provide the preparation formulation of the Herbicidal combinations containing penoxsuam, cyhalofop-butyl and benthiocarb.
