The plant growth‐regulating activity of all the mono‐ and di‐ chloro‐substituted phenylacetic acids, together with the 2:3:6‐trichloro‐ derivative, has been determined in the wheat cylinder, pea segment and pea curvature tests. Each of these compounds showed activity, the 2:3‐dichloro‐ and the 2:3:6‐trichloro‐ derivatives being extremely active. The 3:5‐dichloro‐ acid was inactive in the wheat test but showed moderate activity in the pea tests. All these findings are discussed in relation to the plant growth‐regulating activity of corresponding benzoic and phenoxyacetic acids.
