| Results obtained on the growth response of biotypes of Cynodon dactylon to trichloroacetic acid (TCA) and 2,2-dichloropropionic acid (dalapon), both formulated as the sodium salt, have indicated that the tetraploid biotypes are more resistant than the triploid and that biotypes of the same chromosome number also differ in their response to these herbicides. Investigations on the effects of adding non-ionic, cationic and anionic wetting agents to aqueous solutions of the herbicides in which the leaves of plants were immersed showed that, in general, the wetting agents did not significantly increase the phytotoxicity of either herbicide. Studies on bud dormancy revealed that uptake of TCA and dalapon via the roots is through the transpiration stream and that in tetraploids the dormant period induced by the acids is shorter than in triploids. | |
