The addiction of Ascochyta blight to the list of diseases detected by the DNA-based soil test, PredictaB, will give chickpea growers an extra tool to assess inoculum carryover from previous chickpea crops and help them make more informed decisions on paddock selection.
Stem rust caused devastating crop epidemics and famine for centuries before being tamed by fungicides and resistance genes, but the current global economic loss from wheat stem rust remains high at about US$1 billion a year.
