Description
Technical Field
the invention relates to the technical field of pesticides, and particularly relates to a bispyribac-sodium-cyhalofop-butyl suspension emulsion and a preparation method thereof.
Background
The rice is not only the most important grain crop in China, but also one of the main grain crops in the world. Nearly half of the world's population, including almost the entire east and southeast asia, feeds on rice. Production is throughout continents other than the south pole. In the late part of the last century, the annual output of the rice in the world is about 4000 hundred million kilograms on average, and the planting area is about 1.45 hundred million hectares. The rice seeding area of China accounts for 1/4 of national grain crops, about 3500 more than ten thousand hectares per year, and the yield accounts for more than half. No matter the planting area and the yield, the rice is the top in food crops in China.
However, in all rice fields in rice growing areas in China, a large amount of weeds always occur. Moderate vegetation areas account for over 46% of the total planted area, with severe areas over 11.5%, thereby losing over 200 billion kilograms of grain per year. Therefore, the using proportion of the herbicide in the domestic paddy field almost reaches 100 percent, and the dosage of the herbicide is very large. With the development of agricultural science and technology, the popularization and application of chemical herbicides have been one of powerful yield increasing measures for saving labor, time and cost.
bispyribac-sodium, common english name: bispyribac-sodium, chemical name: 2, 6-bis (4, 6-dimethoxypyrimidinyl-2-oxy) sodium benzoate, molecular formula: C19H17N4NaO8, CAS No.: 125401-92-5 (sodium salt), 125401-75-4 (acid); the structural formula is shown as formula I. Bispyribac-sodium is a herbicide for rice field, has special effect on barnyard grass and paspalum distichum (red-mixed root grass, river-crossing dragon), and can be used for preventing and killing the aged barnyard grass and the barnyard grass which generates resistance to other herbicides.
cyhalofop-butyl, common english name: cyhalofop-butyl, chemical name: (R) -2- [4 (4-cyano-2-fluorophenoxy) phenoxy ] -propionic acid butyl ester of formula: C20H20FNO4, CA accession no: 122008-85-9, the structural formula is shown in formula II. Cyhalofop-butyl aryloxy phenoxy propionic acid herbicide is a selective herbicide for paddy fields, can only be used for treating stems and leaves, has no effect on pre-bud treatment, and is mainly used for preventing and killing gramineous weeds such as barnyard grass, moleplant seeds and the like.
The patent with publication number CN102461511A discloses a mixed herbicidal composition containing bispyribac-sodium and cyhalofop-butyl, which can improve the drug effect, delay the resistance of weeds, have wide herbicidal spectrum and long duration and is safe to rice and next-stubble crops compared with a single agent. The patent also discloses the formulation of the herbicidal composition of bispyribac-sodium and cyhalofop-butyl, which comprises missible oil, suspending agent, water dispersible granules and wettable powder. However, through research, the preparation formulations have the problem of low control effect. Meanwhile, the existing bifenox and cyhalofop-butyl wettable powder in China can generate dust in the production and use processes, and can cause pollution to the environment and people; the suspending agent of bispyribac-sodium and cyhalofop-butyl is easy to have unstable phenomena such as deposition, layering and the like, and the drug effect is seriously influenced; the emulsifiable concentrate of bispyribac-sodium and cyhalofop-butyl contains a large amount of harmful solvents, which causes serious environmental pollution; the cost of the bispyribac-sodium and cyhalofop-butyl dispersible oil suspending agent is too high.
