Comparative evaluation of diseases affection of winter and spring false flax (Camelina sativa (L.) Crantz) in the Krasnodar region

Abstract

We carried out the phytosanitary monitoring of winter and spring false flax (Camelina sativa (L.) Crantz) in the central zone of the Krasnodar region to comparatively evaluate the diseases affection for effective breeding work to develop varieties resistant to the most common and dangerous crop diseases. We noted the same frequency of occurrence of Alternaria blight, Fusarium blight, Sclerotinia blight, bacterial blight and phytoplasma disease on both forms of false flax. We observed the differences between winter and spring false flax in affection by downy mildew, powdery mildew, and white rust. The most harmful of the frequent diseases were downy mildew on winter false flax, and Fusarium blight on spring false flax, so one of the directions in breeding work with false flax is to develop varieties resistant to the affection by these diseases.
