Starchenko S. Root rot of lentil and measures on limitation of its development under southeastern of Ukraine conditions.

Object of researches: plants of lentil (Lens esculenta Moench.), germplasm of collections of culture, agents of a root decay. The purpose of researches - to develop and to insert measures for limitation of development of a root decay of lentil in conditions of a southeast of Ukraine to stabilize productivity of culture and to receive high-quality production. Methods of researches: field, laboratory, statistical. Theoretical outcomes: the specific composition of agents of a root decay of lentil is defined, the dependence speakers of development of illness from the ecological factors is defined, the differentiating germplasm of collections is carried out immunologi, the high performance of fungicides fundazol, witavaks, royalflo. Practical: the data on influence of the meteorological factors on the speaker of a root decay allow to predict its development. Steady against a root decay and early germplasm will be utillized in selection operation. The sort of lentil Svitanok is created steady against a root decay and virus illnesses. The protection system of lentil from a root decay is optimized. Novelty: the agents of a root decay lentil in conditions of a southeast of Ukraine are defined, the correlation link between intensity of illness both metrics of development and efficiency of plants is placed, the functional connection of development of illness from an amount of precipitates, temperatures of air and ground, its dampness is defined, are selected steady against a root decay germplasm, the stability of sorts. The area of application: working out zonal recommendations for lentil protection from injury by root rots. Branch of the use: agriculture.
