Weed Management Under Changing climate

We study the genetic, biology and phenology of weeds and invasive plant species addressing ecological and evolutionary questions in order to improve future weed management 

Newe Ya'ar Research Center, Department of Weed Research and Plant Pathology, Agricultural Research Organization (ARO)

Our research interests are to study the impact of weedy species in agricultural systems. Much of our current research is focused on issues of: invasive weed species, weed control efficacy and herbicide-resistant weeds. We aim to identify key eco-physiological components that may be harnessed to create new integrative and sustainable weed management approaches. 

Key words: Herbicide resistance, Integrated pest management, Invasive weed species, climate change
