Embodiment 1

[0013] Example 1. Take 57kg of xylene, 8kg of dimethyl sulfoxide, 5kg of methanol and 15kg of bentazone, and put them in for stirring in sequence. After the bentazone is completely dissolved, put in 5kg of cyhalofop-methyl, stir, and put 2201 emulsified into the solution after it is completely dissolved. 10kg, and stir evenly to get 20% bentazone-cyhalofop-ethyl emulsifiable concentrate.

Embodiment 2

[0014] Example 2. Take 35kg of xylene, 10kg of dimethyl sulfoxide, 8kg of methanol and 30kg of bentazone, and put them in for stirring in sequence. After the bentazone is completely dissolved, put in 5kg of cyhalofop-methyl, stir, and put 2201 emulsified into the solution after it is completely dissolved. 12kg of agent, and stir evenly to get 35% bentazone-cyhalofop emulsifiable concentrate.

Embodiment 3

[0015] Example 3. Take 48kg of xylene, 10kg of dimethyl sulfoxide, 5kg of methanol and 25kg of bentazone, and put them in order for stirring. After the bentazone is completely dissolved, put 2kg of cyhalofop-methyl, stir, and put 2201 emulsified into the solution after it is completely dissolved. 10kg, and stir evenly to obtain 27% bentazone-cyhalofop-ethyl emulsifiable concentrate.

Abstract

The invention relates to bentazone.cyhalofop-butyl missible oil and belongs to the technical field of pesticide. The aim of the invention is to provide the bentazone.cyhalofop-butyl missible oil with good prevention effect, high safety to paddy and low cost. The bentazone.cyhalofop-butyl missible oil comprises the following main points that: the bentazone.cyhalofop-butyl missible oil is prepared from raw materials and auxiliary materials in percentage by mass: 15 to 30 percent of bentazone, 2 to 5 percent of cyhalofop-butyl, 13 to 18 percent of cosolvent, 10 to 12 percent of emulsifier and a solvent replenished till 100 percent; the solvent, the cosolvent and the bentazone are thrown sequentially and stirred; after the bentazone is fully dissolved, the cyhalofop-butyl is thrown and stirred; after full dissolution, the emulsifier is thrown into the solution; and the mixed solution is evenly stirred to obtain the bentazone.cyhalofop-butyl missible oil. Because the bentazone and the cyhaloop-butyl are compounded and act on different parts inside a weed body according to different weeding mechanisms of the bentazone and the cyhaloop-butyl through combination of advantages of two single weedicides, weeds are killed in different approaches, so that the better weeding effect is achieved. The bentazone.cyhalofop-butyl missible oil is used for preventing and controlling the weeds in a paddy field.

Description

Technical field: [0001] The invention relates to a bentazone-cyhalofop-ethyl emulsifiable concentrate, which is used for preventing and treating weed damage in paddy fields and belongs to the technical field of pesticides. Background technique: [0002] Rice is one of the main crops in our country. With the continuous expansion of its planting area, the weed damage in paddy fields is increasing day by day in the expanding production, and the damage is becoming more and more serious. Can we effectively control the weed damage in rice and stabilize it? The high yield of rice has become one of the main topics of modern agricultural herbicide research. [0003] At present, among the various paddy field herbicides on the market, cyhalofop-butyl (cyhalofop-butyl) is a systemic conduction type aryloxyphenoxypropionic acid herbicide, which is absorbed by plant leaves or leaf sheaths, conducts in phloem, and accumulates with plants. Meristem, inhibit acetyl-CoA carboxylase, stop fat...
