Abstract
The invention relates to a herbicidal composition with synergy. The herbicidal composition has active ingredients of quizalofop-p-tefuryl and acifluorofen sodium in a mass part ratio of 1:1-1:5. The herbicidal composition has an excellent effect of preventing and killing weeds in soybean fields, and is safe for soybeans.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, active ingredient is comprised of quizalofopPtefuryl and acifluorfen.
Background technology
QuizalofopPtefuryl, the careless ester of another name R-sugar, quinoline standing grain health ester, sugared careless ester, chemistry (RS)-2-[4-(6-chloro-quinoxaline by name-2-oxygen base) phenoxy group] propionic acid-2-tetrahydrofuran methyl ester, it is a kind of outstanding sharp leaf weeds herbicide, can be used for broad leaf crop and prevent and kill off most of grassy weed, use for it in Soybean Field is at present domesticly also mentioned without any patent, so the immixture of itself and other composite use of compound is unpredictable.
Acifluorfen is a kind of contact killing type selective post-emergence herbicide, can be absorbed by the weeds cauline leaf, not by root absorption, and easily decomposed by microorganism in soil, thus can not make soil treatment, to soybean safety.Be mainly used in preventing and kill off broad leaved weed.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.Screening by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of pest resistance to insecticide, extend the service life of medicament, is the important means of the agriculture disease pest and weed comprehensive regulation.The inventor is on the basis of the screening of a large amount of indoor virulence and field medicine effect test, and discovery quizalofopPtefuryl and acifluorfen be composite has synergistic function.
Summary of the invention
The objective of the invention is the quizalofopPtefuryl that the mechanism of action is different and acifluorfen and carry out compositely, the Herbicidal combinations of a kind of efficient, low toxicity, low-residual is provided, be used for preventing and kill off soybean weeds.
Technical scheme of the present invention: take quizalofopPtefuryl and acifluorfen as active ingredient, the ratio of quality and the number of copies of quizalofopPtefuryl and acifluorfen is 1:1～1:15, and all the other are to allow in agricultural chemicals to use and the acceptable auxiliary element.
Herbicidal combinations of the present invention can adopt known method to be prepared into suspending agent, water dispersible granules, wetting powder.
The auxiliary element that uses in Herbicidal combinations of the present invention comprises that surfactant, dispersant, filler, filler etc. and other are of value to the known substance of active ingredient stable and performance drug effect in preparation, all various compositions commonly used in pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by simple test according to formula.
Product described in the invention can finished product preparation form provide, namely in composition, each material mixes; The composition of composition also can single dose form provide, directly mix in tank or bucket before use, then be diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation, can reach the purpose of control by using suitable formulation.
Herbicidal combinations of the present invention is used for preventing and kill off the Soybean Field weeding, and using method is cauline leaf spraying after seedling.
Beneficial effect of the present invention is: 1, two kinds of active ingredient is composite has an obvious synergistic effect, has improved control efficiency; 2, two kinds of active ingredients are composite, there is not cross resistance in mechanism of action uniqueness, has reduced the agricultural chemicals usage amount, thereby has reduced cost and the pollution that has reduced environment, be conducive to the resistance comprehensive regulation of weeds, it is applied has larger economic benefit and social benefit.
Embodiment
Below in conjunction with embodiment, content of the present invention is described in further detail, in embodiment, mentioned content is not limitation of the invention, material prescription select to suit measures to local conditions and on result without substantial impact.In these embodiments, unless otherwise indicated, all percentages all are weight percentage.
Embodiment 1:20% quizalofopPtefuryl acifluorfen suspending agent.

Embodiment 2:24% quizalofopPtefuryl acifluorfen water dispersible granules.
Take 4% quizalofopPtefuryl, 20% acifluorfen, 4% lauryl sodium sulfate, 2% polycarboxylic acid salt, 5% naphthalene sulfonic acid condensate salt, 10% urea, 0.5% carboxymethyl cellulose, add starch and mend to 100%.With the mixing in proportion of above-mentioned formula, granulation, drying, screening, make 24% quizalofopPtefuryl acifluorfen water dispersible granules.
Embodiment 3:45% quizalofopPtefuryl acifluorfen wetting powder.
Take 3% quizalofopPtefuryl, 42% acifluorfen, 2% lauryl sodium sulfate, 3% naphthalene sulfonic acid condensate salt, 4% lignin sulfonic acid calcium salt, 5% white carbon and add kaolin to 100%.After above-mentioned raw materials is mixed, make 45% quizalofopPtefuryl acifluorfen wetting powder through air-flow crushing.
Embodiment 4:To the preventive effect of soybean weeds,
Choose 20% quizalofopPtefuryl acifluorfen suspending agent of the embodiment of the present invention 1, be used for preventing and kill off soybean weeds.
Reagent agent and dispenser dosage are as follows.
(1) 20% quizalofopPtefuryl acifluorfen suspending agent (2% quizalofopPtefuryl: 18% trifluoro carboxylic
Grass ether), 300 g/has of effective ingredient consumption.
(2) 4% quizalofopPtefuryl missible oil (contrast single dose), 48 g/has of effective ingredient consumption.
(3) 21.4% acifluorfen aquas (contrast single dose), 480 g/has of effective ingredient consumption.
Dispenser period and application method: cauline leaf spraying after seedling.
Result of the test: see Table 1.Can be found out by result of the test, 20% quizalofopPtefuryl acifluorfen suspending agent of the present invention obviously is better than contrasting single dose to the control efficiency of soybean weeds, and the dosage of pesticide active ingredient is lower than the contrast single dose.
Table 1, the field control effectiveness test result of preventing and kill off soybean weeds.
