Description
Technical Field
The invention relates to a pesticide composition, in particular to a pesticide composition for weeding in paddy fields, which is a ternary herbicide mixture comprising butachlor, penoxsulam and mesotrione as active ingredients, and belongs to the field of pesticides.
Background
With the modern development of agriculture, a series of products such as pesticides, bactericides, herbicides and the like are widely applied, wherein the most popular pesticide product is the herbicide, and the quantity of the herbicide sold is always the top in the pesticide. At present, the market has multiple herbicides, the application technology requirement is high, and the problems of phytotoxicity, poor weeding effect and the like can occur if the herbicides are applied carelessly. Improper selection of herbicides will directly affect the safety risk or yield of the human or seedling plants. With the development of weeding technology and the continuous emergence of herbicides, the resistance of a plurality of weeds in farmlands is enhanced, and with the high-speed development of society, the labor productivity is higher and higher, the labor cost is higher and higher, the novel herbicide is convenient to use, and the herbicide with high weeding efficiency is imperative.
Butachlor is a selective preemergence herbicide, and absorbs young buds and young secondary roots to inhibit the synthesis of protein, so that weeds die, the butachlor is mainly used for preventing and killing annual grassy weeds and annual sedge weeds in rice fields, and certain annual broadleaf weeds, and can also be used for preventing and killing weeds in barley, wheat, cotton and peanut crop fields, for example, the weeds such as barnyard grass, allium fistulosum, iris lactea, felt, Equisetum arvense, and monochoria vaginalis are prevented and killed by 10-30 g of active ingredients/100 m2 in the rice fields, 60% missible oil is used for 2-3 days before rice seedling fields, 6.8g/100m2 in winter wheat and barley are sowed and covered with soil, seedling emergence water or rainfall is irrigated, and under the condition of good soil moisture, the 60% missible oil is used for 15-18.8 m L/100 m2 to uniformly spray the soil surface.
Penoxsulam is a conductive herbicide, is absorbed by stem leaves, buds and root systems, is conducted to meristems through xylem and phloem to inhibit plant growth, so that growing points lose green, terminal buds become red and necrotic after treatment for 7-14 days, and the plants die in 2-4 weeks; the agent is a strong acetolactate synthase inhibitor, is slow in appearance, and gradually dies after a certain time. The penoxsulam is suitable for direct seeding dry land, direct seeding water land, seedling land and seedling throwing and transplanting cultivation land of rice. The dosage is 15-30 g a.i./hm 2. Directly sowing the seedlings in the dry land before germination or after irrigation, and directly sowing the seedlings in the water in the early stage after seedling; the transplanting and cultivating are carried out 5-7 days after the transplanting. The application method can be spraying or soil mixing treatment. Penoxsulam is a broad-spectrum herbicide for rice fields, can effectively control barnyard grass (including barnyard grass with resistance to propanil, quinclorac and acetyl coenzyme A carboxylase), moleplant seed and annual sedge weeds, and is effective on a plurality of broadleaf weeds, such as marsh pistil, carp intestine, sesbania, Japanese chikura, monochoria vaginalis and the like. The lasting period is as long as 30-60 days, and the harm of weeds in all seasons can be basically controlled by one-time application. Meanwhile, the herbicide can prevent and kill bensulfuron methyl weeds in rice fields, has residual activity on a plurality of broadleaf and cyperaceae weeds, barnyard grass and the like, and is a variety with the widest weed control spectrum in the current herbicides for the rice fields.
Mesotrione is a triketone compound. The pure product is light yellow solid in appearance, is a broad-spectrum selective herbicide capable of inhibiting hydroxyphenylpyruvate dioxygenase (HPPD) before and after germination, can effectively control piemarker, amaranth, chenopodium quinoa, polygonum, barnyard grass, crab grass and other main broadleaf grasses and some gramineous weeds, and both a mesotrione technical and a 100 g/L mesotrione suspending agent belong to low-toxicity herbicide removal agents.
In the actual use process, the butachlor has good effect on the grassy weeds and can only prevent and remove part of broadleaf weeds; penoxsulam is a broad-spectrum herbicide and has good effect on a plurality of broadleaf weeds and gramineous weeds, and mesotrione mainly prevents and removes broadleaf weeds and part of gramineous weeds. The three herbicides have own weeding characteristics, and the butachlor, the penoxsulam and the mesotrione are reasonably mixed, so that the herbicide composition has the effects of expanding a weeding spectrum, reducing the application times and reducing the control cost.

From tables 1 and 2, it can be seen that the herbicide composition of the present invention not only has good killing effect on both gramineous and broadleaf plants, but also has improved overall control effect due to the synergistic effect of different components, and the drug effect is exerted quickly. Meanwhile, the pesticide effect of the pesticide composition is not greatly different after 10 days and 20 days of application, and the control effect of the pesticide composition after 20 days of single application is slightly lower than that of the pesticide composition after 10 days of single application. This shows that the pesticide composition of the present invention has lasting effect and less resistance to weeds, especially malignant weeds.
TABLE 3 safety investigation results of the agents on crops
The herbicide composition of the invention is observed to be safer than a single agent and has little effect on crops. Therefore, the pesticide composition is suitable in proportion, easy to degrade, safe to rice and free of side effect; the residual period in soil is short, and the fertilizer is safe for the succeeding crops. After the three active ingredients are used together, the harm of each pesticide to crops is further reduced, and the withering and death rate of the crops is obviously lower than that of the pesticide combination used singly or in the prior art.
