Abstract
The invention discloses weeding composition containing saflufenacil and trichlopyr. The weeding composition comprises saflufenacil and trichlopyr serving as effective ingredients as well as the balance of a pesticide adjuvant, wherein a weight ratio of saflufenacil to trichlopyr in the composition is 1:1-1:50, and the weight sum of saflufenacil and trichlopyr accounts for 1%-60% of the weight of the composition. An oil suspension and wettable powder can be prepared from the weeding composition during actual application; weeding composition has the synergistic effects when used for controlling and removing broadleaf weeds in uncultivated areas, orchards, ridges and the like, the effect of the weeding composition is better than that of separate use of saflufenacil and trichlopyr, the application dosage of a pesticide is reduced, the adverse effect of the pesticide on the ecological environment is reduced, and the problem of pesticide resistance of the weeds is effectively solved.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically a kind of Herbicidal combinations containing benzene flumetsulam and trichlopyr.
Background technology
Chemical method weeding is one of Main Means of agriculturally control of weeds, the researcher in synthetic chemistry field invention polytype except immunomodulator compounds and compound formulation, a lot of compound and compound formulation are open in the literature, and a large amount of herbicidal compounds preparation is at agricultural use.Pest in scientific prevention and cure agricultural production, effectively improve compound to disease, worm, prevention and control of weeds effect, plant protection researcher explores a set of feasible method in long-term practice work.
Evaluate described in weed killer herbicide mode of application (NY/T1155.7-2006) evaluation criterion according to Colby method, Multiple Pesticides carries out combining to rake mark virulence performance " synergy ", be two or more factor interactions, evaluate combination acts synergistically and show synergy or addition or antagonism.The present invention is measured by indoor virulence test, pharmaceutical formulation screens, field efficacy checking, based on following discovery: the wherein one of known independent herbicidal compounds (a) benzene flumetsulam and (b) 2 first 4 chlorine, trichlopyr combines, to most broad leaved weed synergistic function, improve herbicidal effect.
Benzene flumetsulam (saflufenacil), chemical name: N ＇-[the fluoro-5-of the chloro-4-of 2-(3-methyl-2,6-dioxy-4-(trifluoromethyl)-3,6-dihydro-1 (2H)-pyrimidine) benzoyl]-N-isopropyl-N-methyl sulphamide.Benzene flumetsulam is proporphyrinogen oxidase (PPO) inhibitor, can effectively prevent and kill off multiple broad leaved weed, comprise glyphosate, and ALS and triazines produce the weeds of resistance.
Trichlopyr (triclopyr), chemical name: 3,5,6-trichloro-2-pyridyl fluoroacetic acid.Trichlopyr rapidly by leaf and root absorption, and can conduct in plant corpus.Act on metabolism of nucleic acid, make plant produce excessive nucleic acid, make some structural transformations become meristematic tissue, cause blade, stem and root growth deformity, reserve substance exhausts, and vascular tissue is by embolism or break, and plant is dead gradually.
The present invention conducts in-depth research benzene flumetsulam and trichlopyr, on the basis of a large amount of tests, finds that benzene flumetsulam and trichlopyr combine, and to most broad leaved weed performance synergistic function, significantly improves herbicidal effect.After further study, the present invention is completed.
Summary of the invention
Technical problem to be solved: the object of the invention is to the synergistic function utilizing benzene flumetsulam and trichlopyr, provides a kind of efficient, low cost, is conducive to the Herbicidal combinations of the weeds comprehensive regulation.
Another object of the present invention is to provide the broad leaved weed being applied to by this Herbicidal combinations and preventing and kill off uncultivated area, orchard, farmland.
Technical scheme: for achieving the above object, the invention provides a kind of Herbicidal combinations being active ingredient with benzene flumetsulam and trichlopyr, active ingredient is benzene flumetsulam and trichlopyr, benzene flumetsulam and trichlopyr weight ratio is in the composition 1:1 ~ 1:50, benzene flumetsulam and trichlopyr weight summation in the composition percentage by weight are 1% ~ 60%, and surplus is insecticides adjuvant.
Described Herbicidal combinations is prepared into the one in oil-suspending agent, wetting powder by pesticide production technology.The production technology of various application forms all belongs to existing known technology, does not repeat them here.
Herbicidal combinations provided by the invention, can be applicable to the broad leaved weed preventing and kill off uncultivated area, orchard, farmland.
Herbicidal combinations provided by the invention, usually adopts the method for directed spraying to use, also can adopt other operation techniques agriculturally applied as required.
Compared with prior art, composition provided by the invention has following beneficial effect:
1, synergistic function, improves and uses herbicidal effect.
2, reduce single compound formulation, circulation cost, reduce material and use, reduce energy resource consumption.
3, the single compound mechanism of action contained by composition is different, overcomes single compound easy to the biological problem producing resistance of rake mark for a long time, extends the service life of compound, to the comprehensive regulation important in inhibiting of Weed Resistance.
Embodiment
In order to understand essence of the present invention better; below in conjunction with embodiment, content of the present invention is described further; but can not limitation of the present invention be considered as; the following stated is only for explaining the present invention; for not departing from amendment that the present invention's spirit and principle make, replacement or improvement, all belong to the scope of protection of present invention.
Embodiment 1: composition synergism determination.
At the in-built quantitative soil of the polypots of high 6cm, diameter 9cm, will for 15 ~ 20 sowings of examination target weed seed in polypots, be placed in greenhouse after the fine earth that lid 0.5 ~ 1cm is thick and cultivate, treat that weeds grow to 5 ~ 7cm and carry out spraying process, every alms bowl spraying liquid 1mL, often process repetition 4 times, and set the process not containing medicament as contrasting.After process, examination material is placed in greenhouse and cultivates, the growing state of routine observation target weeds.Take acrial part weeds fresh weight after test process 20d, calculate dense EC in suppression by method of least squares
50.
Evaluate weed killer herbicide associated form (NY/T1155.7-2006) according to Gowing method, its formula is as follows:
In formula:
X be benzene flumetsulam alone with certain dosage time fresh weight inhibition to target weeds;
Y be trichlopyr alone with certain dosage time fresh weight inhibition to target weeds;
E
0for when benzene flumetsulam and trichlopyr two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibition or desired value;
E be benzene flumetsulam and trichlopyr two kinds of pharmacy mix time to target weeds fresh weight inhibition be contrast measured value or observation.
Evaluation criterion: as E ﹣ E
0during > 10%, be expressed as synergistic function; As ﹣ 10%≤E ﹣ E
