Abstract

A trial was conducted to study the phytotoxic effects of contact and systemic herbicides on oil palm seedlings in the pre-nursery. Thirteen herbicides each at three rates of application were sprayed onto the soil surface in the polybag. Germinated oil palm seeds were sown in the polybags at three 14 and 28 days after spraying. Results from this study indicated that Assault 100A Tordon 101 Ustinex Special and Garlon 250 caused very severe phytotoxicity to the oil palm seedlings at three and 14 days after spraying for all rates tested. The phytotoxic symptoms caused by systemic herbicides were different from non-emergence where the shoot of the germinated seed is an empty cavity instead of a growing point. At normal rate Dasatox 325 2 4-D. Duron 80 and Starane 200 caused moderate injury while Roundup and Paraquat produced slight injury. No phytotoxic symptoms were observed with MSMA and Basta at this rate. However MSMA and Basta were phytotoxic when applied at twice the normal rate three days before sowing.
