Resumen o descripción

Water extracts of Calea urticifolia Mill. for the control of Meloidogyne incognita. Nematropica 39:289-296. Water extracts of roots and leaves of Calea urticifolia Mill. were evaluated for the control of Meloidogyne incognita on tomato cv Rio Grande grown in pots. The number of galls per plant and the number of eggs per g of macerated roots were evaluated for application times of 0, 24, 48 and 72 hours after transplant and extract concentrations of 0, 50 and 100% as measured by number of galls per plant, both root and leaf extracts gave the same control (Tukey, P = 0.05). This was also true with extract concentrations where 50 and 56% galling reduction were obtained with both 50 and 100% concentrations respectively, compared to untreated plants. Root extract concentrations inhibited egg numbers per plant by 20% more than those treated with leaf extracts. For this parameter, the full concentration inhibited egg production by 72% compared to the untreated control, and the half concentration inhibited egg production by 31%, regardless of the origin of the extract. The lowest egg numbers per plant was obtained when extracts were applied at planting (45% reduction) and 72 h after planting (48% reduction).
