Use of a synergistic herbicidal combination including a glufosinate- or glyphosate-type, imidazolinone or protoporphyrinogen oxidase to control weeds in rice

摘要

A combination of herbicides (I) and (II) is used to control weeds in rice crops, where (I) is a glufosinate- or glyphosate-type herbicide an imidazolinone or a protoporphyrinogen oxidase (PPO) inhibitory azole herbicide and (II) comprises one or more compounds selected from: herbicides of type (I) other than (I) itself. A combination of herbicides (I) and (II) is used to control weeds in rice crops, provided that the crops are tolerant of (I) and (II), optionally in the presence of safeners, where: (I) is selected from: (A1) compounds of formula (Ia) and (Ib) and their esters and salts: Z = OH, NHCH(CH3)CONHCH(CH3)COOH or NHCH(CH3)CONHCH(CH2CH(CH3)2)COOH; (A2) imidazolinones; or (A3) PPO inhibitory azole herbicides; and (II) comprises one or more compounds selected from: (B1) herbicides of type (I) other than (I) itself; (B2) rice-selective herbicides with both foliar and soil (residual) activity against monocot and dicot weeds; (B3) rice-selective herbicides active against dicot weeds and/or sedges; (B4) rice-selective herbicides with foliar activity against monocot weeds; and (B5) rice-selective herbicides with both foliar and soil activity against monocot weeds. Independent claims are also included for the following: (1) a method for controlling weeds in tolerant rice crops, comprising applying (I) and (II), together or separately, pre- and/or post-emergence, to the plants, parts of the plants, seeds or soil; (2) a herbicidal composition comprising (I) and (II); (3) use of the composition of (2) for regulating the growth of rice plants; (4) use of the composition of (2) for modifying the yield or contents of rice plants.
