Abstract
Phytotoxicity to 7 crop species, and degree of inhibition of the Hill reaction were assessed for several 2‐azido‐4‐alkylamino‐6‐alkylamino‐s‐triazines. Biological activity increased with increased alkylation of the amino groups, with increasing chain length of the alkyl substituents up to 5 to 6 C atoms, and with increased degree of branching of the alkyl chain. For several of the compounds tested there was good agreement between phytotoxicity tests and potency against the Hill reaction. The most active compound was 2‐azido‐4‐ethylamino‐6‐t‐butylamino‐s‐triazine (WL 9385), which was particularly effective in controlling seedling annual grasses when applied post‐emergence.Keywords
