BIOLOGICAL METHOD PROTECTION OF THE SUGAR BEET AGAINST PATHOGENIC FUNGI CAUSING ROOT ROT
Published: 1 Jun 2014
Abstract: From the rhizosphere of the healthy plants of sugar beet, 43 new strains of cellulolytic bacteria were isolated, 12 strains have antagonism against pathogenic fungi of the genus Fusarium, causing root rot and seedling of sugar beet. Two strains of bacteria with high antifungal and growth promoting activities were selected. Field tests have shown, that inoculation seeds of the cellulolytic bacteria infestation of fusariosus seedling decreased by 2.0-2.4 times, and the prevalence of root crops - 2.5-3.0 times as the control and increase sugar beet yield amounted to 30-34 c/ha. On the basis of these strains was developed a biological method for stimulating the growth and protection of sugar beet against root rot.
