Problems solved by technology

[0004] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Too long effective period, excessive dosage or uneven application will easily cause r

Abstract

The invention discloses a weeding composite containing pentoxazone and penoxsulam, and application thereof. The weeding composite takes pentoxazone and penoxsulam as main effective ingredients, wherein the mass ratio of pentoxazone to penoxsulam is (1:50)-(59:1). The weeding composite can be used for the weeding of paddy fields, and especially has an outstanding effect for preventing and removinggrass family, sedge family and broad leaf weeds. According to the weeding composite, on a premise that a pesticide effect is improved for a single dosage, weed resistance is delayed, a weeding spectrum is broad, a lasting period is long, and in addition, the weeding composite has safety for paddies and afterreap crops.
