| Abstract |
The purpose of this study was to significantly reduce the amounts of herbicides necessary to control certain noxious weeds. In laboratory and field studies herbicides were applied with certain plant hormones to accelerate their uptake and translocation in plants. Treatment of redtop grass with IAA or GA increases its sensitivity to 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine). It was also found that simultaneous application of either IAA or GA with 2-(2,4,5-trichlorophenoxy)propionic acid (silvex) enhanced the toxic efficiency of the herbicide on poison ivy. Residue analyses of plants treated with only the herbicide were compared. More silvex was found in the plants treated with IAA or GA. In the laboratory the influence of GA, 2,4-D, and parachlorophenoxy-acetic acid (PCPA) on the uptake of naptalam by bean plants was studied. Bean plants pretreated with GA via a liquid medium (root absorbed) took up and accumulated considerably more naptalam than untreated plants. The synthetic growth regulators 2,4-D and PCPA were even more active in this respect. |
