Abstract
The invention provides an oil suspension type herbicide containing cyhalofop-butyl and penoxsulam, relating to the technical field of production of pesticides. The oil suspension type herbicide is composed of effective components including the cyhalofop-butyl and the penoxsulam, wherein the cyhalofop-butyl accounts for 8% of the total mass of the herbicide; the penoxsulam accounts for 2% of the total mass of the herbicide; and the oil suspension type herbicide also contains 8% of a dispersion wetting agent, 1% of an anti-freezing agent, 1% of a thickening agent, 2% of a de-foaming agent and 78% of a filler. The oil suspension type herbicide contains the effective components including the cyhalofop-butyl and the penoxsulam, and can be applied to prevention and removal of various weeds including direct seeding paddy field barnyard grass, leptochloa chinensis, nutgrass flatsedge, convexutricle sedge herb, wild water chestnuts, short sagittaria sagittifolia, alternanthera philoxeroides and paspalum distichum at the periphery of four ridges are good; the oil suspension type herbicide is safe to crops and has low cost and good prevention effect; and the herbicide composition has a stable chemical performance, is efficient and broad-spectrum, and has obvious broad-spectrum weeding and supplementary effect on prevention and removal objects.
Description
Technical field
The present invention relates to the production technical field of agricultural chemicals.
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 the grassy weed such as moleplant seed, barnyard grass 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 moleplant seed, barnyard grass generating capacity are large, make 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.
Cyhalofop-butyl is a kind of efficient, low toxicity diphenyl ether herbicide, paddy field selective herbicide.This kind is prevented and kill off in process can only be used as cauline leaf process at direct seading rice field weed, and bud pre-treatment is invalid.Be mainly used in preventing and kill off barnyard grass, the grassy weeds such as moleplant seed.Herbicide for paddy field kinds all at present is obviously better than to the preventive effect of moleplant seed.
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.
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 formulation with oil-suspending agent, has weed killer herbicide that is efficient, broad spectrum weeding function simultaneously.
The present invention is made up of active ingredient cyhalofop-butyl and penoxsuam, and it is characterized in that cyhalofop-butyl accounts for 8% of weed killer herbicide gross mass, penoxsuam accounts for 2% of weed killer herbicide gross mass, dispersion moisture agent 8%, antifreeze 1%, thickener 1%, defoamer 2%, filler 78% forms.
The present invention with cyhalofop-butyl and penoxsuam for active ingredient, apply 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, 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.
Embodiment
One, 10% cyhalofop-butyl penoxsuam oil-suspending agent is prepared:
Take cyhalofop-butyl 8kg, penoxsuam 2 kg, polyoxyethylene nonylphenol ether (NP-9) (dispersion moisture agent) 8 kg, propane diols (antifreeze) 1 kg, xanthans (thickener) 1 kg, silicone defoaming agent (SAG612) 2 kg and methyl oleate (filler) 78 kg respectively.
After cyhalofop-butyl and penoxsuam are first fully mixed in enamel stirred tank, add other raw material again, again stir 30 minutes, stir again after sand milling, namely obtain the large packaging of finished product, finished product meets or higher than every compulsory index requirement of country to missible oil and oil-suspending agent product.
Two, effect:
Get 30 milliliters/mu, preparation that said method makes, 40 milliliters/mu, 50 milliliters/mu preventive effects to paddy rice barnyard grass, moleplant seed, nutgrass flatsedge, result of the test shows: preventive effect, all more than 90%, is also better than cyhalofop-butyl and penoxsuam two products are alone simultaneously.
table 1 10% cyhalofop-butyl penoxsuam oil-suspending agent prevents and kill off rice direct seeding field
after annual weed control efficiency (%)-dispenser, strain in 45 days is prevented
