Abstract

Between forty species of plant parasitic nematodes harmful to strawberries, the most common species of nematodes are Aphelenchoides fragariae and Meloidogyne hapla. Nematode species A. fragariae cause twisting and puckering of leaves, delayed development of the plants, reddened and stunted petioles, flowers talks with aborted or partly aborted flowers and lowering yields strawberries to 60 %. In addition to crop rotation and planting of healthy plants, a significant role in preventing the spread of this pest has a sinking seedlings in water heated to 43.3 ° C for 20 min. Species M. hapla is harmful in strawberry production outdoors and in greenhouses. The infection is recognized based on the appearance of root nodules and the formation of many fine roots. Plants of strawberries become dwarf, leaves become chlorotic and red, what it is followed by reduced yield. The most infected plants can be completely dry. As this species has about 550 host plants, the selection of plants in the rotation is demanding. Reducing populations of these nematodes is achieved by draining of the soil, weed control, planting enemy plants (Tagetes spp., Asparagus spp.) and the planting of resistant and tolerant plants. The best results are achieved by thermal sterilization of the soil, solarization and chemical sterilization before planting.
