Uso de la torta de mamona no controle de nematoides em solo para viveiro de café
The authors, hoping to find a substitute for the use of methyl bromide in the plant beds, investigated the incorporation of plant cakes into the soil. This study used castor bean cakes, which have a low cost and have value as a fertilizer. Soil, highly infested with Meloidogyne exigua was mixed with 0.75, 1.5, and 3.0 percent castor bean cake. A portion of the soil did not receive the addition of castor bean cakes (one check plot) and another was treated with methyl bromide (a second control area). On the same day as the treatment, part of the soil was planted with coffee seedlings at an age referred to as "orelha de onça". At 10, 20, 30, 40, 50 and 60 days following the addition of the castor bean cake, other portions of soils were planted in a like manner. Soil treated with methyl bromide was planted only at the initiation of the experiment. The data obtained at the termination of the study included the average height of the plants, their average weights, average weights of the above-ground and below-ground parts and the degree of infestation by M. exigua indicated on a scale of O to 5 (Table I). There appears to be potential for the substitution of the methyl bromide treatment by the addition of castor bean cakes to the soil in plant beds. Addition study is warrented. It should be noted a natural desinfestation occurred in the untreated control plots. The incidence of M. exigua was zero after 50 days, with an initial decline noted after 20 days
