Abstract
The invention relates to a herbicide composition containing cyhalofop-butyl and thiocarbamate. The herbicide composition is mainly characterized by comprising 1 to 40 weight percent of active ingredient A, namely cyhalofop-butyl, 5 to 60 weight percent of active ingredient B, auxiliary agents and other excipients, wherein the active ingredient B is selected from thiobencarb and molinate; and the herbicide composition is prepared into a suspension agent, emulsion in water and microemulsion. The herbicide composition is used for preventing and controlling annual gramineous weeds of paddy fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of contain the effective constituents A cyhalofop-butyl with the Herbicidal combinations of thiocarbamates, be used to prevent and treat the paddy field annual weed.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active height; (3) selectivity height.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Cyhalofop-butyl (cyhalofop-butyl), molecular formula: C
20H
20FNO
4, relative molecular mass 357.4.It is the aryloxy carboxylic acid weed killer herbicide of LG-DOW agricultural science company exploitation.Seem unique kind that paddy rice is had tight security in the fragrant phenoxy propionic acid class weed killer herbicide, inhale conductivity in having, blade and the leaf sheath carried by plant absorb, the phloem conduction accumulates the meristem zone in plant corpus, always acetyl-CoA carboxylase, fatty acid is synthesized to be stopped, the division of cell can not normally be carried out, and film system etc. contains ester structure and destroys, and causes plant death at last.In the paddy rice body, cyhalofop-butyl can be degraded to the diacid attitude to the acetyl-CoA carboxylase non-activity rapidly, and paddy rice is had safety highly, and degraded rapidly in soil and in the typical paddy field water either.Be mainly used in the control grassy weed, not only the barnyard grass natural plant height imitated, also can prevent and treat weeds such as moleplant seed, lady's-grass.
Benthiocarb (thiobencarb) also claims weed eradication pellet, benthiocarb, Benthiocarb, straw pellet, molecular formula: C
12H
16ClNOS is by the dithiocarbamate herbicide of Japanese combinatorial chemistry company exploitation, is the lipoid synthetic inhibitor, but is not the ACC enzyme inhibitor.The selective herbicide that belongs to a kind of inner sucting conduction type suppresses the biosynthetic process of α-Dian Fenmei, the starch hydrolysis of chitting piece kind is weakened or stops, and makes young shoot death.Main young shoot and root absorption by weeds to not effect of suppressing weed seed germination, have only to absorb medicament just work behind weed germination.
Molinate (molinate) also is molinate, molecular formula: C
9H
17NOS, relative molecular mass 187 is the dithiocarbamate herbicides by Syngenta Co.,Ltd's exploitation.Be the lipoid synthetic inhibitor, but be not the ACC enzyme inhibitor.Molinate is a kind of paddy field herbicides special of inner sucting conduction type, impose on Tanaka, because its density is greater than water, and be deposited in the interface of water and mud, form the medicine layer of high concentration, when weeds pass through the medicine layer, can be gone out to take root, especially be absorbed rapidly by bud scale, and be accumulated in the meristematic tissue of growing point, stop protein synthesis.Can also suppress alpha-amylase activity, stop or weaken the hydrolysis of starch, protein synthesis machine cell division degradedness is supplied with.The cell of being injured expands, and the growing point distortion is and dead, and the seed rice of well ridge vernalization is sowed on the medicine layer, and it is few that the rice root is passed down through medicine layer absorption dose.Bud scale upwards growth thereby can not be injured by the medicine layer, and concrete symptom is the weeds back young shoot swelling of being injured, and stops growing, and blade thickening, look dense, and plant is downgraded deformity, and lobus cardiacus can't pump out, and is dead gradually.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of benthiocarb, molinate about cyhalofop-butyl.

Benthiocarb solution: accurately take by weighing the former medicine of 0.205g93% benthiocarb, with the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to benthiocarb 750g a.i./ha solution, again with clear water be diluted to 500,250a.i./ha concentration is standby.
Molinate solution: accurately take by weighing the former medicine of 0.1926g99% molinate, with the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to molinate 750g a.i./ha solution, again with clear water be diluted to 500,250a.i./ha concentration is standby.
Blank solution: the 1mL vegetable oil adds the water of 80mL 0.1% agricultural newborn 600#.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): the amount of setting soil in the polypots of high 6cm, diameter 9cm, will be in polypots for 15～20 sowings of examination target weed seed, be placed on cultivation in the greenhouse after covering the thick fine earth of 0.5～1cm, treat that weeds grew to for 2～4 leaf phases and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL, every processing repeats 4 times, and establishes the contrast that is treated to that does not contain medicament.Handle the back examination and just place in the greenhouse in and cultivate, the growing state of routine observation target weeds, be injured symptom and growth inhibition situation of range estimation target behind the 15d, and title acrial part fresh weight or strain fresh weight are with the toxicity action of form fresh weight inhibiting rate evaluation medicament to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are handled behind the 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
Estimate weed killer herbicide synergy mode (NY/T 1155.7-2006) according to the Gowing method, its formula is as follows:
E
0＝X+Y-XY/100
In the formula, X is that cyhalofop-butyl is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that benthiocarb or molinate are with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for cyhalofop-butyl and benthiocarb or two kinds of pharmacy mix of molinate to the theoretical value of target weeds fresh weight inhibiting rate; When E is cyhalofop-butyl and benthiocarb or two kinds of pharmacy mix of molinate to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0Be expressed as synergistic effect at＞10% o'clock, as 10%≤E-E
0Be expressed as summation action, and worked as E-E in≤10% o'clock
0Be expressed as antagonism at＜-10% o'clock.
