Efficacy of selected insecticide to against whitefly (Bemisia Tabaci) on chilli plant (Capsicum annum) / Nur Azirah Mohamad Fazi
Whitefly, Bemisia tabaci (Genn), is one of the most damaging pests for several vegetables in Malaysia which affects plant vigour, transmits geminiviruses and reduces crop quality. These studies focus on efficacy of selected insecticide Confidor 200SL (imidacloprid) and Mospilan 20SP (acetamiprid) ag...
