In wet foothill and hilly-steppe zones of the Altai Province, USSR, Helminthosporium sativum infection on barley roots was markedly decreased and grain yields increased by adopting the following measures: early sowing of disease-free, large seeds treated with fungicides at a depth of 3-4 cm after fallow or peas, application of P or NPK, and practising cultivation techniques aimed at increasing soil-moisture content. The sowing of barley after sunflower or maize for silage and/or application of N alone increased infection. The decrease in infection on primary roots depended on seed quality and that on secondary roots depended on agronomic practices.
