Manejo Integrado De Nematodos Fitoparasitos Y Cosmopolites Sordidus (germar) En El Cultivo De Platano

Resumen del Libro

Plant-parasitic nematodes and the banana weevil Cosmopolites sordidus are recognized as the most limiting factors for plantain production in Puerto Rico. The use of pesticides has been the traditional method for pest control, which has generated environmental and human health problems. A study was conducted at the Isabela Agricultural Experimental Substation to develop integrated management practices for the control of both pests in plantains. The experimental design was a RCB with five treatments and four replicates. Plantain (Musa acuminata x M. balbisiana, AAB, cv. Maricongo) was used as the planting material. The treatments were: T1. Rotation of velvet bean (Mucuna deeringiana) + plantain, T2. Poultry litter (7.3 Kg/plant) + plantain, T3. Rotation of velvet bean + poultry litter + plantain, T4. Chemical control (Nemacur 15G 3.0g a.i./plant/at 6 and 12 months after planting) + plantain, and, T5. Absolute control. Phytonematode populations were recorded at the end of the first rotation cycle and at intervals of four months thereafter. (Abstract shortened by UMI.)
