Control of weeds in tolerant maize crops uses herbicidal combination containing glufosinate, glyphosate, imidazolinone, azole, cyclohexanedione or heteroaryloxyphenoxypropionic acid herbicide

摘要

Weeds in tolerant maize crops are controlled by the application of a herbicidal combination comprising a glufosinate (I) or its esters, salts or phosphinothricin derivatives, glyphosate (II) or its ester or salt, imidazolinone, protoporphyrinogen oxidase-inhibiting azole, cyclohexanedione or heteroaryloxyphenoxypropionic acid herbicide and selective or non-selective herbicides. Control of weeds in tolerant maize crops comprises the application of a herbicidal combination comprising: (A) a glufosinate of formula (I) or its esters, salts or phophinothricin derivatives, glyphosate of formula (II) or its esters and salts, imidazolinone, protoporphyrinogen oxidase-inhibiting azole, cyclohexanedione or heteroaryloxyphenoxypropuionic acid herbicide; and (B) herbicide(s) which are: (a) structurally different from herbicides (A); (b) active against monocot and dicot weeds via foliage or soil; (c) active selectively against dicots in maize; and/or (d) active selectively predominantly against dicot weeds via foliage or soil; and (C) optionally a safener. Z = OH, -NHCH(CH3)CONHCH(CH3)COOH or -NHCH(CH3)CONHCH(CH2CH(CH3)2)COOH. Independent claims are also included for: (i) the use of the combination for regulating the growth of maize plants or for influencing the yield or components of maize; and (ii) a herbicidal composition containing (A) and cyanazine, acetochlor, alachlor, terbutryn, benoxacor, fluthiamide, sulcotrione, mesotrione, penthoxamid, pendimethalin, iodosulfuron, metosulam, isoxaflutole, metribuzin, cloransulam, flumetsulam, florasulam, isoxachlortole, bromoxynil, clopyralid, carfentrazone, Lab271272, halosulfuron, diflufenzopyr and/or sulfosulfuron as (B) and optionally adjuvants and formulation aids.
