Compound herbicide for paddy field

Abstract

The invention relates to a compound herbicide for a paddy field. The compound herbicide for the paddy field contains the following components in parts by weight: 40-50 parts of florasulam, 10-15 parts of fluroxypyr-mepthyl, 10-30 parts of pendimethalin and 50-60 parts of a solvent. The herbicide also comprises 5-10 parts of pyrithiobac sodium. The herbicide has obvious synergy and effect of enhancing the killing effect, the duration is prolonged, and obtains good preventing and removing effect for multiple grassy weeds and broad leaf in the paddy field; besides, the herbicide is low in toxicity and wide in herbicide controlling spectrum, the dosage, drug delivery time and drug use cost are remarkably lowered, and the service life of the herbicide is prolonged.

Description

technical field [0001] The invention relates to a herbicide, in particular to a paddy field herbicide. Background technique [0002] With the continuous use of many herbicide varieties in large areas of rice fields, many problems have arisen, such as the outstanding weed resistance, and the resistance of barnyardgrass to propanil, quinclorac, butachlor, and carbap. It is more prominent. Recently, common weeds such as Cyperaceae, Cyperaceae, Alismaceae and other common weeds such as Heterocarpus sedge, Yinglin, Sagittarius, Yujiuhua, and Coriaceae have developed resistance to sulfonylurea herbicides. The problem of weeding is becoming more and more complicated; the damage of perennial weeds has become an important problem, especially the perennial weeds of Cyperaceae; The duration of soil treatment chemicals; the demand for herbicide varieties with broad spectrum, strong selectivity and easy use is more urgent.
