Abstract
The invention relates to herbicide composition. The herbicide compositioncomprises effective components, namely,benzobicylon and oxadiargyl, wherein the weight part ratio of the benzobicylon to the oxadiargyl is in a range of 30:1-1:30. The herbicide composition has an obvious synergistic effect on barnyard grass and dayflower, can improve the weed eradication effect, can expand the herbicide controlling spectrum and is applicable to control on annual weeds in paddy fields.
Description
Technical field
The invention belongs to agriculture weeding technical field, be specifically related to a kind of Herbicidal combinations taking benzobicylon, Bing Que Evil humulone as active ingredient, be applicable to prevent and kill off paddy field annual weed.
Background technology
Along with progressively eliminating of high-toxic pesticide, need efficient, low toxicity, safety, environment amenable pharmaceutical preparations, the long-term use of agricultural chemicals simultaneously produces the pesticide resistance of disease pest and weed, requirement to control medicament is also more and more higher, this just needs agricultural chemicals research staff to develop the pharmaceutical preparations of highly effective and safe, meets control requirement.Because China's agricultural chemicals initiative is at the early-stage, the pesticide species with independent intellectual property right can't be satisfied the demand, and the therefore pesticide mixed preparation of development of new is the only way of current Agrochemicals.
Benzobicylon is the research and development of Japanese SDS bioscience Co., Ltd., compound patent expires in January, 2014, be mainly used in preventing and treating paddy field barnyard grass, annual broadleaf weed and sedge weed, the weeds that sulfonylurea produced to resistance have good preventive effect, can effectively prevent and kill off the paddy field weeds such as barnyard grass, firefly Lin, Monochoria vaginalis, pondweed, false rice by soil treatment, just can reach desirable preventive effect to short arrowhead high dose, lasting period can reach 6 weeks, this compound be at present in the world a unique energy on paddy rice, use and to the effective medicament of false rice.
Bing Que Evil humulone Shu Yu oxadiazole ketone weed killer herbicide, the inhibitor that the mechanism of action is proporphyrinogen oxidase.Can effectively prevent and kill off paddy field annual gramineous weed, broad-leaved, sedge weed and the water silk flosses such as firefly Lin, barnyard grass, wild water chestnut, cyperus iria, difformed galingale herb, needle spikesedge herb, mexicana, little najas marina, moleplant seed, convexutricle sedge herb, Monochoria vaginalis, Monochoria korsakowii, rhizoma alismatis, short arrowhead, arrowhead, bur beggar-ticks, pondweed.
Weed killer herbicide is rationally composite is to improve preventive effect, expand herbicide spectrum or widen service time, delaying the speed of shift of weed community, reducing the resistance risk that the single use of agricultural chemicals brings, alleviate the pollution to environment, reduce a kind of effective ways of use cost and reduction herbicide residue.The inventor conducts in-depth research the mixture of benzobicylon, Bing Que Evil humulone, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that benzobicylon, Bing Que Evil humulone carry out mixture, within the scope of certain mixed ratio, barnyard grass, Monochoria vaginalis are shown to synergistic function, be applicable to prevent and kill off paddy field annual weed, after further study, completed the present invention.
Summary of the invention
The object of the invention is to solve the deficiency that weed killer herbicide is single while using, provide a kind of efficient, low toxicity, low cost, quick-acting good, and the lasting period is long, is conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Technical scheme of the present invention is: a kind of Herbicidal combinations, formed by active ingredient benzobicylon, Bing Que Evil humulone and suitable insecticides adjuvant, and the ratio of weight and number of benzobicylon and Bing Que Evil humulone is 30:1～1:30.
Described Herbicidal combinations by certain technological means can excipient water dispersible granules, the formulation that uses in the applicable agricultural such as wetting powder.
Described Herbicidal combinations is processed into water dispersible granules, and each weight percentages of components is: benzobicylon 0.1%～80%, and Bing Que Evil humulone 0.1%～80%, surfactant 1%～20%, all the other are carrier.
Described Herbicidal combinations is processed into wetting powder, and each weight percentages of components is: benzobicylon 0.1%～80%, and Bing Que Evil humulone 0.1%～80%, surfactant 1%～20%, all the other are carrier.
Described Herbicidal combinations is processed into water dispersible granules, wetting powder, and surfactant is one or more of neopelex, lauryl sodium sulfate, lignosulfonates, aliphatic alcohol sulfate, aliphatic alcohol polyethenoxy, sodium butylnaphthalenesulfonate, naphthalenesulfonate formaldehyde condensation compound and polycarboxylic acid; Carrier is one or more in kaolin, attapulgite, bentonite, diatomite, talcum powder, precipitated calcium carbonate, urea, white carbon.
The production technology of the described various application forms of Herbicidal combinations all belongs to existing known technology, does not repeat them here.
Herbicidal combinations provided by the invention, is applicable to prevent and kill off paddy field annual weed.
Herbicidal combinations provided by the invention has following beneficial effect:
1, Herbicidal combinations provided by the invention, for paddy field chemical weed control provides a kind of economy, environmental protection, efficient solution.Composition has expanded the herbicide spectrum of benzobicylon and Bing Que Evil humulone single dose, within the scope of 30:1～1:30, barnyard grass, Monochoria vaginalis are shown to obvious synergistic function, the control efficiency of composition has had raising than single dose, reduce the using dosage of agricultural chemicals, reduced drug cost and the agricultural chemicals risk to ecotope adverse effect.
2, Herbicidal combinations provided by the invention, can reduce the resistance risk that the single benzobicylon of long-term use or Bing Que Evil humulone produce, and extends the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
