Abstract

Rose clover (Trifolium hirtum All.), subterranean clover (T. subterraneum L.), and crimson clover (T. incarnatum L.), were sprayed at different growth stages with 2,2-dichloropropionic acid dalapon), and two formulations of 4-(2,4-dichlorophenoxy)-butyric acid [4-(2,4-DB)], in two growing seasons. Herbage yields, seed yields, and seed quality were for the most part unaffected by either formulation of 4-(2,4-DB) at the dates required for weed control. Only subterranean clover was tolerant of dalapon and then only at very low rates.
