Description

A kind of Herbicidal combinations that contains cyhalofop-butyl

Technical field

The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains effective constituents A cyhalofop-butyl and active ingredient B, be used to prevent and treat paddy field barnyard grass grass, moleplant seed, grassy 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.

Anilofos (anilofos), molecular formula: C 13H 19ClNO 3PS, relative molecular mass 367.8 is weed killer herbicides of Sanofi-Aventis's exploitation.Anilofos belongs to cell division inhibitor, be interior suction conduction selective herbicide, medicament mainly in the young shoot by plant and the ground stem absorb, suppress cell division and elongation, weeds are subjected to grow behind the medicine and stop, blade is dark green, sometimes decolouring, blade shortens and thick, very easily fractures, young leaves is difficult for extracting out, and whole at last strain is withered.

Oxazine humulone (oxaziclomefone), molecular formula: C 20H 19Cl 2NO 2, relative molecular mass 376.3 is the weed killer herbicides by Sanofi-Aventis's exploitation.Clomazone is mainly used in broad leaved weed, sedge weed and Echinochloa weeds, to rice safety.

Clomazone (clomazone), molecular formula: C 12H 14ClNO 2, relative molecular mass 239.7 also is clomazone, is the weed killer herbicide of FMC Corp.'s exploitation.Clomazone is the carotenoid biosynthesis inhibitor, and is synthetic by suppressing pentylene compound, hinders carrot and chlorophyllous biosynthesis, absorbs, upwards dredges, and diffuse to leaf portion through xylem through plant roots, young shoot.Though sensitive plant can be unearthed in rudiment, owing to do not have pigment to form Bai Miao, and dead in a short time.

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 about the relevant composite product of cyhalofop-butyl with anilofos, clomazone Huo oxazine humulone.

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 anilofos is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E 0During for cyhalofop-butyl and two kinds of pharmacy mix of anilofos to the theoretical value of target weeds fresh weight inhibiting rate; When E is cyhalofop-butyl and two kinds of pharmacy mix of anilofos 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.
