Description
Technical field
The present invention relates to pesticide production technology field.
Background technology
Paddy rice is the main food long-term cropping of China, and national rice growing area is stabilized in about 4.5 hundred million mu always for many years.Along with the continuous propagation and employment of paddy rice cultivation technique, direct seading rice development is particularly swift and violent.Because it has the huge advantage of dart transfer, liberating rural productivity, progressively become a kind of tool rice cropping mode with broad prospects for development in China main paddy rice producing region at present.Due to planting type and the feature in direct seading rice field, the crop smothering generation problem in direct seading rice field is very outstanding.
Direct seading rice field weed kind is with grassy weeds such as barnyard grasses for sociales, and how and early go out grass, maximum to rice hazard, being secondly the broad leaved weed such as Monochoria vaginalis, pondweed, is sedge weed again.With plough compared with transplanting rice field, due to direct sowing rice weed and paddy rice synchronous growth, especially barnyard grass generating capacity is large, makes weeds generation total amount high.For direct seading rice field weed occurrence characteristic, current weed control is still prevented and kill off based on chemical agent, closes down process and cauline leaf process of tagging combines before taking bud, prevents and kill off in conjunction with cultivation simultaneously, thus effective its occurrence and infection of control.In chemical agent is prevented and kill off, the main pesticide species used has at present: Jing Ke Cao Xing wetting powder, 10% bensulfuron-methyl, 20% methoxone aqua and 25% Bentazon missible oil etc.These products due to service life longer, weeds drug resistance is greatly increased.
Penoxsuam is translocated herbicide, through cauline leaf, young shoot and Root Absorption, conducts to meristematic tissue by xylem and phloem, suppresses plant strain growth, makes growing point chlorosis, and after process, 7 ~ 14d terminal bud reddens, downright bad, and within 2 ~ 4 weeks, plant is dead; This agent is strong inhibitor of acetolactate synthetase, and medicament presents comparatively slow, needs certain hour weeds just dead gradually.Be applicable to the direct-sowing dry field of paddy rice, direct-sowing rice, rice seedling bed and rice transplanting, rice transplanting cultivation field.Consumption is 15 ~ 30g a.i./hm2.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.Effectively can prevent and kill off barnyard grass (comprising the barnyard grass to Stam F-34, dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), annual sedge weed, and effective to numerous broad leaved weed, as raw different in natural pond stamen flower (Heteranthera limosa), carp intestines (Eclipta prostrata), sesbania (Sesbania exaltata), ring flower (Commelina diffusa), Monochoria vaginalis (Monochoria vaginalis) etc.Lasting period reaches 30 ~ 60 days, a drug energy basic controlling full season Weed infestation.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., but invalid to moleplant seed weeds, as needed control, and can be mixed with cyhalofop-butyl.For the kind that herbicide spectrum in current herbicide for rice field is the widest.
Pyribenzoxim is novel oxime ester compound, wide spectrum selective post-emergence herbicide.It is similar that mechanism of action and sulfonylurea and imidazoles stay type herbicides, all belongs to acetolactate synthestase (ALS) inhibitor.To paddy rice, common wheat, Korea lawn grass, there is activity of weeding after selectivity super-high-efficient bud, without activity of weeding before bud, for prevent and kill off the various grassy weed such as barnyard grass, large fringe amur foxtail, polygonum flaccidum and broad leaved weed effect distinguished, to paddy rice, common wheat safety.Chemical weeding speed is comparatively slow, can suppress weed growth after dispenser, but must be withered after 2 weeks.
Summary of the invention
The object of the invention is the multiple weak point existed for current wide spectrum, highy potent herbicide shortage and existing weed killer herbicide, providing a kind of is product forms with missible oil, has weed killer herbicide that is efficient, broad spectrum weeding function simultaneously.
Active ingredient of the present invention is made up of penoxsuam and pyribenzoxim, and it is characterized in that penoxsuam accounts for 5 ~ 25% of weed killer herbicide gross mass, pyribenzoxim accounts for 3 ~ 25% of weed killer herbicide gross mass, and all the other are emulsifier and solvent.
The present invention adopt penoxsuam and pyribenzoxim composite, there is efficient, broad spectrum weeding function, expand weeding scope simultaneously, effective to multiple prevention and control of weeds such as direct seading rice field barnyard grass, moleplant seed, nutgrass flatsedge, convexutricle sedge herb, wild water chestnut, short arrowhead, water peanut and four ridge surrounding Paspalum distichums, crop is had no adverse effects, exceedes the use of penoxsuam and pyribenzoxim two single dose kinds.
Preferred penoxsuam accounts for 2% of weed killer herbicide gross mass, and pyribenzoxim accounts for 3% of weed killer herbicide gross mass.
Emulsifier account for weed killer herbicide gross mass 5 ~ 15%, solvent accounts for 35 ~ 87% of weed killer herbicide gross mass.
Described solvent is at least one in dimethylbenzene, toluene, methyl alcohol, cyclohexanone, dimethyl formamide, isophorone.
Described emulsifier is at least one in WJD-100, agriculture breast 500, NP-10, OP-10, Tween 80.
The present invention applies preventing and kill off in the multiple crop smotherings such as direct seading rice field barnyard grass, moleplant seed, nutgrass flatsedge, convexutricle sedge herb, wild water chestnut, short arrowhead, water peanut and four ridge surrounding Paspalum distichums, and to crop safety, cost is low, preventive effect good.Proving after tested, herbicidal composition stable chemical nature of the present invention, high-efficiency broad spectrum, revealing obvious broad-spectrum weed-killing and complementation to preventing and kill off Object table.
Advantage of the present invention: penoxsuam and these two kinds of combination of active principles of pyribenzoxim use, and expand weeding scope and herbicidal effect.Through test determination: penoxsuam is used for preventing and kill off the grassy weeds such as barnyard grass and broad leaved weed, be obviously better than herbicide for paddy field kinds all at present.And although pyribenzoxim is a kind of broad-spectrum herbicide, annual after paddy field seedling and perennial broadleaf weed is prevented and kill off all there is good effect.Therefore penoxsuam and pyribenzoxim composition to the direct seading rice owner of farmland wide spectrum of wanting Weed infestation to reach and synergistic effect the most remarkable.Secondly use cost reduces, current penoxsuam and pyribenzoxim single dose use cost higher, it is not again fine that low dosage is used alone effect, and therefore penoxsuam and pyribenzoxim combinationally use preventive effect and improve, again reduce agriculture this.
