Abstract
The invention relates to weed control foliar herbicide compositions in a paddy field, which are three foliar herbicide compositions for eliminating weeds in the paddy field. The three foliar herbicide compositions are the composition of mesotrione and metamifop, the composition of mesotrione and cyhalofop-butyl and the composition of mesotrione and penoxsulam respectively. The single use of the existing herbicide in the paddy field has the limited weed-killing spectrum and can not control all the weeds in the paddy field, and a complex product has poor safety or a narrow using cycle or resistance to the weeds in a water field, thereby limiting the popularization and the applications of the complex product. The three herbicide compositions provided by the invention can overcome the defects and control all the weeds in the paddy field; furthermore, the three herbicide compositions have broader using cycle, no resistance to the weeds in the water field and good safety to paddy rice and succeeding crops.
Description
Technical field: [0001] The invention belongs to the field of agricultural herbicides. Background technique: [0002] With the development of science and technology, chemical weeding in paddy fields has changed the usual farming and cultivation modes in traditional agricultural production, which can save labor and greatly increase production. The representative varieties of rice field weeding are the sulfonylurea herbicides such as bensulfuron-methyl and pyrazosulfuron-methyl for the control of broad-leaf weeds, and the amide herbicides butachlor and acetochlor for the control of gramineous weeds They are all closed herbicides with a narrow use period and many years of use, and problems such as phytotoxicity of soil residues to crops and replacement of weed populations have occurred, such as individual secondary weeds (Dianjinzi) Rising to be the main weed in paddy fields; quinclorac and fenoxaprop-ethyl are used alone or mixed with bensulfuron-methyl, pyrazosulfuron-methyl...
