Recent trends and techniques in weed management under protected environments

Abstract

In green house grown crops, weeds are the major threat which competes with main crops in all growing factors such as light, water and nutrients. Also weed act as a primary source of pest, disease and nematodes. Integrated weed management approach is helpful to control weed problem in greenhouse cultivation. Integrated management approaches include preventive, physical control measures, chemical control measures and mechanical measures. Since the greenhouse cultivation is under controlled condition it is essential to avoid invading of weeds inside the structure at initial stage itself. Weeds may spread through seeds, manures, machineries, tools and implements. Hence, Sanitsing and cleaning all the tools and implements is necessary.
