Harmfulness of root rot of barley.
In the Voronezh region Helminthosporium sativum [Cochliobolus sativus] and Fusarium sp. reduce growth, wt. of green matter and yield of barley. Seed dressing with Granosan [ethylmercury chloride] at 2 kg/t reduced incidence by 25-60% and increased yield by 3-12%. Dusting seeds with 1% trichothecin at 2 kg/t (using wetting agent and sticker) reduced incidence by a factor of 1.5-2 and increased yield by 1.1-6.1 centners/ha.
