Description
The technical field is as follows:
the invention relates to the field of herbicide preparation, in particular to a compound herbicide suitable for alfalfa fields in northeast China.
Background art:
alfalfa is one of the important pastures in China, is well known as the king of pastures, has high yield and excellent quality, and is favored by various livestock and poultry. With the development of animal husbandry, planting and forestry and grass industry, the demand of alfalfa is increasing year by year. At present, the area of alfalfa in China is kept at 300 million hectares, the alfalfa industry is gradually increased at a speed of 50 million hectares every year, the alfalfa industry becomes a sunward industry in China, along with the enlargement of the planting area, in the alfalfa planting process, weeds have great harm to alfalfa, about 200 million hectares of alfalfa are damaged by weeds every year, most of the weeds grow rapidly in the alfalfa seedling period, and strong competition with alfalfa seedlings in the aspects of nutrition, moisture, illumination and the like is formed, so that the yield, the quality and the palatability of the alfalfa are reduced. It can be seen that weeds become a key factor for restricting the success and failure of alfalfa seeding, and the quality and the yield of alfalfa are directly influenced without solving the problem of weeds.
Currently, in alfalfa weed control, a single weed control agent is commonly used, such as imazethapyr, bentazone, clethodim, kukungfeng, clopyralid, sethoxydim, and the like. Among these herbicides, there are monocotyledonous weeds such as clethodim and sethoxydim, and monocotyledonous plants such as barnyard grass, green bristlegrass, tiger tail, wild oats and the like are mainly controlled; also can prevent and kill dicotyledonous weeds, such as imazethapyr, bentazone, kungfeng, clopyralid, and the like, and mainly prevent and kill dicotyledonous plants such as bowl flower, spikelet, purslane, chenopodium glaucum and the like. In the alfalfa field in northern China, dicotyledonous plants and monocotyledonous plants exist, when weeds are prevented and removed, different types of preventing and removing agents are required to be sprayed for many times, and a period of time is required after spraying, so that the components for inhibiting the growth of the alfalfa are prevented from being generated after the preventing and removing agents are mixed, the whole spraying period is long, the production cost is increased, the efficiency is low, and the preventing and removing effect is not ideal. Sometimes the optimal time for preventing and removing weeds is delayed, the preventing and removing agent is usually sprayed when the weeds are 2-5cm, the growth speeds of various weeds are inconsistent, the time is long when the preventing and removing agent is sprayed for multiple times, and the optimal time for preventing and removing monocotyledonous weeds is often missed when the dicotyledonous weeds are prevented and removed; if a plurality of control agents are sprayed at the same time, the control effect of weeds is influenced, and the growth of alfalfa is also influenced in serious cases.
The invention content is as follows:
the invention provides a compound alfalfa herbicide, which is suitable for preventing and removing annual or perennial gramineous weeds and broadleaf weeds in alfalfa fields such as barnyard grass, green bristlegrass, tiger tail grass, wild oat, goosegrass, leaf mustard, redroot amaranth, purslane, chenopodium glaucum, atriplex villosa, polygonum aviculare and the like, is sprayed once without waiting, has good weed prevention and removal effect and high working efficiency, greatly shortens the spraying period, reduces the production cost, can accurately master the optimal time for preventing and removing weeds, effectively avoids harmful ingredients generated among various herbicides which are not compounded, influences the growth of alfalfa, and solves the problems in the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a compound herbicide suitable for alfalfa land in northeast is prepared by compounding an imidazole acetic acid herbicide, a bentazone herbicide, an ketene herbicide and an auxiliary agent, wherein the imidazole acetic acid herbicide, the bentazone herbicide and the ketene herbicide are compounded according to the mass ratio of 0.2-0.8: 1.9-7.7: 0.9-3.9.
The compound herbicide is an aqueous emulsion or a microemulsion; the auxiliary agent is used for preparing microemulsion or aqueous emulsion; the dosage of the auxiliary agent is 90-99.5 wt% of the total amount of the compound herbicide.
Further, the preferable compound herbicide comprises the following raw materials:
a compound herbicide comprises the following components in percentage by weight: 0.39 wt% of imazethapyr herbicide, 3.74 wt% of bentazone herbicide, 1.87 wt% of ketene herbicide and 94.0 wt% of auxiliary agent.
A compound herbicide comprises the following components in percentage by weight: 0.64 wt% of imazethapyr herbicide, 6.21 wt% of bentazone herbicide, 3.15 wt% of ketene herbicide and 90.0 wt% of auxiliary agent.
A compound herbicide comprises the following components in percentage by weight: 0.06 wt% of imazethapyr herbicide, 0.53 wt% of bentazone herbicide, 0.25 wt% of ketene herbicide and 99.16 wt% of auxiliary agent.
The characteristics of the herbicides employed in the present invention are as follows:
among the herbicides of the present invention, imazethapyr herbicides: the herbicide composition is mainly used for preventing and removing gramineous weeds and broadleaf weeds in leguminous crops, and has the advantages of strong selectivity, wide weed control spectrum, high activity and the like. Such as: amaranth, black nightshade, siberian cocklebur, green bristlegrass, millet and the like. The acetohydroxy acid synthetase can be prevented in time, the biosynthesis of valine, leucine and isoleucine is influenced, the protein of the acetohydroxy acid synthetase is damaged, and the plant growth is inhibited and dies gradually. Research shows that the herbicide has better control effect on gramineous weeds and broadleaf weeds in alfalfa fields, and withers and dies within 2-4 weeks; after the soil treatment, the meristem at the top of the weeds is necrotic and growth is hindered, and although some weeds can germinate and emerge, the weeds gradually die when growing to 2.5-5 cm.
Among the herbicides of the present invention, bentazone herbicides: the main action object is to prevent and kill Cyperaceae and broad-leaved weeds, and specifically comprises Scirpus planiculmis, rhizoma pleionis, water chestnut, monochoria vaginalis, Equisetum diffusum, sedge heterotypii, Sparganium stoloniferum, Xanthium sibiricum, purslane, Capsella bursa-pastoris, Stellaria medialis, Datura stramonium, Abutilon, Ambrosia artemisii, Cyperus rotundus, Polygonum hydropiper and the like. Studies show that bentazone is safe to alfalfa.
Among the herbicides of the present invention, the enoxolone herbicides: selective herbicide, systemic conductive type, high-selectivity stem and leaf treating agent. Can be used for preventing and killing annual and perennial grassy weeds, such as barnyard grass, wild oat, crab grass, green bristlegrass, goosegrass herb, blue grass, stiff grass and other grassy weeds. Inhibiting fatty acid synthesis in plant body, delaying plant growth, and making plant implement chlorosis and necrosis in 1-3 weeks after application. Clethodim is safe for alfalfa.
In the herbicide, the imidazole acetic acid herbicide and the bentazone herbicide only kill dicotyledonous plants (broad-leaved plants) except alfalfa, such as quinoa, mustard, redroot amaranth, artemisia plants and the like, and have no influence on the growth of the alfalfa; while the ketene herbicides only have killing effect on monocotyledons (narrow-leaf plants), such as barnyard grass, green bristlegrass, wild oats and the like. In the alfalfa main production area in northeast China, weeds are mainly dicotyledonous plants, so that two herbicides for killing the dicotyledonous plants are selected to enhance killing, and the herbicides for killing the monocotyledonous plants are matched to effectively prevent and kill weeds around the alfalfa.
By adopting the scheme, the weeds growing around the alfalfa are effectively prevented and removed, the weeds and the alfalfa seedlings are prevented from fighting for water and nutrition, and the yield and the quality of the alfalfa are greatly improved.
