Afegir etiqueta | Sumari: | The kidney nematode, Rotylenchulus reniformis is one of the most important in the vegetables in the Ecuadorian coastal region. Spreads between areas by farm machinery and tools, irrigation water, transplantation of infested material. This work took place in the greenhouse of the Faculty of agricultural sciences, Technical University of Babahoyo, located in the kilometer 7 ½ track Babahoyo-Montalvo in Los Ríos province. The object was to determine the threshold damage of the nematode kidney R. reniformis in tomato cv. "Floradade", pepper cv. "Irazu long" and melon cv. "47 Edisto". Investigated populations of R. reniformis present the transplant at levels of 50, 100, 150, 200, 250, 300, 350, 400 and 500 per 100 cm3 of soil were treatments with 5 repetitions composed each of three plants. Used the design completely at random. 60 Days after the transplant was assessed, height of plants (length of melon plants), weight of the air side, fresh weight of roots, number of galls in roots by plant and density of R.reniformis in roots and soil by each plant. |
