Patogenicity of originators of fusarial wilt of root rot on pease (Pisum sativum L.)

Abstract

The purpose. To determine pathogenic properties of fungi of genus Fusarium Link. spread on plants of pease. Methods. Laboratory (secretion in clean culture of originators of root rot of pease, growing and accumulation of contagious stuff; growing of plants of pease in conditions of artificially infected soil), mathematical-statistical. Results. In conditions of artificially infected background pathogenic properties are studied of fungi of genus Fusarium on pease. Influence is determined of kinds of Fusarium upon germination of seeds, seeding emergence, fungal attack, further growth of plants. Conclusions. The greatest injuriousness to pease manifested F. Avenaceum and F. javanicum, the least — F. oxysporum.
