Screening of glyphosate, fluazifop-p-butyl or glufosinate susceptible and resistant biotypes of goosegrass in Selangor, Johor, Kelantan and Pahang

Abstract

Eleusine indica is currently considered as world's fifth worst weed which caused problem in agriculture sector in more than 60 countries. In Malaysia, it causes a major threat in the oil palm plantation area. This study aims to screen for the herbicide resistance and susceptible biotypes namely glyphosate, fluazifop-p-butyl or glufosinate in Selangor, Johor, Kelantan and Pahang. In this study 14 different population involving farms and plantation areas were screened. From the 14 populations, four populations were detected to be resistance towards glyphosate, which involves farm of sugar cane, Kuala Selangor, Ciku farm, Selayang, Vegetable farm, Sekinchan, Selangor and oil palm nursery, Layang-layang, Johor with the percentage of survivability of 70.25, 86.6%, 86.4% and 92.3% respectively.
