Interactions between tri‐S‐butyl phosphorotrithioate (DEF) and growth regulator herbicides: I.—A preliminary report

摘要

AbstractMixtures of tri‐S‐butyl phosphorotrithioate (DEF) emulsion and the potassium salt of picloram were strongly synergistic when applied as foliar sprays to pot‐grown privet, poplar, guava andEucalyptusplants. A similar but less marked effect was observed in privet, using mixtures of DEF and a water‐soluble amine formulation of 2,4,5‐T. By contrast, mixtures of an oil‐soluble ester formulation of 2,4,5‐T with DEF were antagonisti
