Abstract
On 14 month-old nursery oil palm 1 litre of diluted herbicide solution was poured on the soil around the collar of the palms. Symptoms of injury were observed on palms treated with glyphosate dicamba glyphosate fluroxypyr imazapyr paraquat diuron metsulfuron-methyl and glyphosate 2 4-D isopropylamine. Glyphosate alone did not result in any injury symptom. Palms with basal treatment by metsulfuron-methyl glyphosate 2 4-D isopropylamine and glyphosate metsulfuron-methyl recovered after 150 days. Partial recovery was observed on palms treated with paraquat diuron. Topical (direct) spraying of 150 ml per palm was done using a knapsack sprayer fitted with a fan nozzle (5/64 in). Results showed that injury was induced by 2 4-D sodium salt DSMA diuron glyphosate paraquat diuron glufosinate-ammonium glyphosate dicamba glyphosate fluroxypyr triclopyr glyphosate 2 4-D isopropylamine imazapyr glyphosate metsulfuron-methyl and paraquat metsulfuron-methyl. No visual phytotoxicity was observed when cinosulfuron or metsulfuron-methyl were sprayed topically. The implications of these research findings are discussed
