Where growers were unable to secure supplies of mancozeb, the risk of early blight (Alternaria solani and A. alternata) also became a threat, especially to susceptible maincrop varieties. “Crops were always likely to come under pressure from alternaria and late blight at some point, the question was when,” says Eric Anderson, senior agronomist at Scottish Agronomy. “The challenge was how best to manage the twin threat of early blight and late blight in crops at vastly different stages because of the protracted start to the season. For some, achieving this in practice was a logistical challenge,” he adds.
