Preliminary investigation of multiple resistance in goosegrass (Eleusine indica) to premix of diuron and MSMA, glyphosate, clethodim, quizalofop in Malaysia

Background The primary challenge in Malaysian vegetable farms is the herbicide resistance in E. indica. Objective: This study aimed to assess herbicide resistance in E. indica biotypes on a cucumber farm in Penang, Malaysia. Methods Seedlings of the putative resistant and susceptible biotypes were propagated and transferred into seedling trays containing peat moss. The seedlings were subjected to premix of diuron and MSMA, glufosinate, glyphosate, oxyfluorfen, napropamide, quiazlofop and clethodim treatments at the three-to-four-leaf stage. Results Dose-response tests showed [...]
