## Abstract Smallβplot trials with formulations of ethyl ester and the trimethylamine salt of 2 : 4βdichlorophenoxyacetic acid (2,4βD) are described. These showed that the ester was more effective than the amine salt against individual weed species at rates of application of 1/2 lb./acre or less. T
Following i.p. administration of various doses of 2-methyl-4-chlorophenoxyacetic acid (MCPA), ca. 50% is excreted during a 5-h diuresis experiment. After i.p. administration of MCPA, virtually no distribution occurs (Vre, = 18% of the body weight). Renal excretion of MCPA can be accelerated by inhib
