US 2014/0155265 A1 · HERBICIDAL COMPOSITIN COMPRISING PINOXADEN AND FLUROXYPYR AND METHODS OF USE THEREOF

Abstract

The invention provides a liquid herbicidal composition in the form of an emulsifiable concentrate, comprising a mixture of: (i) pinoxaden; (ii) a C1-C12alkyl ester or a 2-(C1-C6alkoxy)C2-C4alkyl-ester of fluoroxypyr; and (iii) a built-in phosphate and/or phosphonate adjuvant as defined herein; preferably tris-(2-ethylhexyl) phosphate. The invention also provides a method for controlling and/or inhibiting the growth of weeds from the genus Kochia, comprising applying a liquid herbicidal composition to these weeds or to their locus, at a time after emergence of the weeds, wherein the liquid herbicidal composition comprises a mixture of: (i) pinoxaden; (ii) a ester of fluoroxypyr; and (iii) a built-in phosphate and/or phosphonate adjuvant as defined herein. The invention also provides methods for controlling and/or inhibiting dicotyledonous and/or broadleaf weeds, preferably weeds from the genus Kochia, Polygonum, Fallopia, Salsola, Descurainia, Helianthus, Lactuca, Solanum, Sinapsis, Amaranthus, Brassica, Chenopodium and/or Fagopyrum. The invention also provides a liquid herbicidal composition, which has herbicidal activity against a broad spectrum of broadleaf weeds, comprising a mixture of: (i) pinoxaden; (ii) an ester of fluoroxypyr; and either (a) pyrasulfotole, and bromoxynil or an ester thereof; or (b) MCPA or an ester thereof, and a fourth herbicide which is florasulam, prosulfuron or triasulfuron.

and
(b) applying the diluted aqueous liquid herbicidal composition to the dicotyledonous and/or broadleaf weeds, or to the locus thereof, at a time after emergence of the weeds;
and wherein the first herbicidal composition is liquid and comprises a mixture of:
(ia) pinoxaden;
(ib) a C1-C12alkyl ester or a 2-(C1-C6alkoxy)C2-C4alkyl-ester of fluoroxypyr;
and
(ic) a built-in phosphate and/or phosphonate adjuvant;
