Abstract
The invention relates to a composite herbicide containing triclopyr and flucarbazone-sodium, which is prepared from the triclopyr and flucarbazone-sodium according to the weight ratio of (0.5-8) to 1. The invention also discloses application of the composite herbicide in preventing and controlling weeds in wheat fields. The two agents can respectively kill different groups of weeds with high efficiency, and have obvious synergistic effect after being compounded, thereby accelerating the exertion of drug effect and reducing the dosage of the herbicide, thereby improving the safety of the herbicide to wheat fields. The weed control spectra of the two medicaments are complementary, and after the two medicaments are mixed, the weed control spectra can effectively cover common weeds in a wheat field, so that the market potential is huge.
Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a weeding composition and application thereof.
Background
Wheat is one of the three major grains, is almost all eaten, and only about one sixth of the wheat is used as feed. The two river basin is the earliest region for cultivating wheat in the world, and China is one of the earliest countries for cultivating wheat in the world. Wheat in 2010 is the second food crop of the world in total production (6.51 hundred million tons), second only to corn (8.44 hundred million tons). China has a large population, and the guarantee of national food safety is always the first major thing for treating national political affairs. Wheat is one of the most important food in China, and the quality and the yield of wheat are one of the basic tasks of the planting industry in China. Weed damage is one of the important threats faced in wheat planting. The main method for preventing and controlling the weeds in the farmland is to use chemical agents.
Chemical weeding in farmlands in China starts in 1954, and in the past 50 years, the herbicide industry in China has gone through a diffuse process from introduction to introduction, and from imitation to creation. According to statistics, nearly 200 herbicide varieties (effective components) registered by Ministry of agriculture are obtained in sequence since pesticide registration is carried out in China in 1982, more than 300 mixed pesticide combinations are obtained, and more than 1500 raw pesticide products and preparation products are obtained. 7 herbicide varieties are independently created in China, and the herbicide varieties are monosulfuron, monosulfuron-ester, methisulfuron-methyl, pyraclofos-methyl, propyl ester grass ether, isopropyl ester grass ether and clofenphos-methyl. Various selective herbicides currently known have narrow herbicidal spectrum and are easy to generate drug resistance, for example, continuous application of the herbicide is easy to generate drug resistance. Therefore, the combination of the herbicides capable of controlling different groups of weeds becomes one of the solutions to the problems.
The flucarbazone-sodium is a sulfonylurea systemic high-efficiency wheat field herbicide, and has obvious control effect on gramineous weeds such as wild oats, brome, alopecurus, and the like and various dicotyledonous weeds. The compound is a brand new compound, the active ingredients of the compound can be absorbed by the roots, stems and leaves of weeds, and the weeding activity is exerted by inhibiting the activity of acetolactate synthetase in the weeds and destroying the normal physiological and biochemical metabolism of the weeds. The powerful tiger can effectively prevent and kill off most gramineous weeds in the wheat field and can also effectively control part broadleaf weeds. The powerful tiger can be metabolized quickly in the wheat body and has excellent safety to the wheat.
Triclopyr is a pyridyloxycarboxylic acid herbicide, is systemic, conductive and low-toxic, belongs to hormone herbicides, is absorbed by leaf surfaces and root systems of plants, and is transmitted to the whole plant in the plant body, so that the root, stem and leaf of the plant are deformed, vascular bundles are plugged or broken, and the plant dies gradually. Gramineous crops have a certain resistance to them. The weeding composition is suitable for weeding, killing and irrigating before forest forestation, maintaining fire lines, supporting pine trees to breed and improving forestry, preventing and removing broadleaf weeds and woody plants in non-cultivated land, and can also be used for preventing and removing broadleaf weeds in fields of gramineous crops such as wheat, corn, sorghum and the like.
Disclosure of Invention
The invention aims to provide a compound herbicide with low toxicity, safety, high efficiency, environmental protection and wider action spectrum.
The invention aims to solve the technical problem of providing a composite herbicide capable of efficiently and safely preventing and removing weeds in wheat fields.
In order to achieve the purpose, the invention provides the following technical scheme:
a composite herbicide containing triclopyr and flucarbazone-sodium has the effective components of triclopyr and flucarbazone-sodium; the weight ratio of triclopyr to flucarbazone is 0.5-8: 1, the total weight of the triclopyr and the flucarbazone is 1 to 40 percent of the composite herbicide, and the balance is pesticide auxiliary agent.
According to the physical and chemical properties of the two raw medicines, a proper pesticide auxiliary agent is selected, and the product can be prepared into a dispersible oil suspending agent.
The composite herbicide also contains an auxiliary agent required for preparing a pesticide preparation, wherein the auxiliary agent is one or a mixture of several of a solvent, an emulsifier, a co-emulsifier, a stabilizer, a dispersant, a thickener, a pH regulator, a defoaming agent, an antifreezing agent and the like, is a known substance, is various auxiliary agents commonly used in pesticide preparations, and is changed according to different situations without special limitation.
Can be applied by spraying. The weeding composition is diluted by water to prepare the required concentration, and is uniformly sprayed on crops or other control objects by a sprayer.
The composite herbicide provided by the invention shows obvious addition effect in a certain proportioning range, enlarges the weed control spectrum, obviously improves the control effect of the combination compared with single use, and reduces the use dosage. The dosage is reduced, the medication cost is reduced, and the influence of the pesticide on the ecological environment is reduced.
