Abstract

Evaluation of the pathogenicity of the nematode Longidorus leptocephalusmeasured by the variation in its numbers on strawberry (Fragaria ananassa) and blackberry (Rubus caesius) plants in vegetative environments was carried out. As a result we demonstrated that strawberry plants developed symptoms of backwardness in their growth relative to controls with an average number of 80 individual nematodes per 100 g of soil and50% plant death for strawberries was recorded at a level of 600 nematodes per 100 g of plant rhizosphere. On blackberry plants a significant effect of growth-inhibition was found at a level of 500 individuals per 100 g of soil, but plant death was not registered.
