Surfactant adjuvant compounds of formula (I) where R?1, R2, R3, R4, and R5¿ have defined meanings can be used with particular effect with glyphosate type herbicides to kill weed species that are recognised as particularly difficult to kill. Examples of such weeds are broad leaved (dicotyledon) weed such as Chenopodium album, Solanum nigrum, Lactuca saligna, Amaranthus retroflexus and Erigeron canadensis (annuals) and Cirsum arvense (perennial) and similar related weeds from these genera and perennial monocotyledon such as Lolium perenne, Convolvulus arvensis and, especially, Agropyron repens and similar related weeds from these genera. |
