The potential of antitranspirants in drought management of arable crops: A review

About 80 % of global farmland is under rain-fed conditions and most of it is prone to drought, which limits crop productivity. Due to climate change, drought will become more frequent and severe, threatening world food security. Antitranspirants, materials that reduce transpiration, could potentially result in greater food production by realising more of a crop’s potential yield during drought. Despite antitranspirants reducing photosynthesis,...
