EVALUATION OF ALTERNATIVE PRODUCTS FOR PLAGUE CONTROL AND PHYSIOLOGICAL QUALITY OF STORED COWPEA SEEDS

摘要

The efficiency of natural products and chemical aluminum phosphite, in the physiological and sanitary quality of stored cowpea seeds (Vigna unguiculata L. Walp.) variety Cariri, in the municipality of Solanea City, PB during six months of storage was evaluated. A completely randomized statistical design was used in a 9x7 factorial scheme represented by nine treatments and seven storage periods, with four replications. The physiological quality of the seeds was checked from the beginning up to 30 days of storage and the following parameters were evaluated: mean moisture content, infestation rate, germination and vigour (emergence in field). The results allowed to conclude that the cowpea seeds, during storage presented a reduced physiological quality. The most efficient alternative products for controlling infestation on seeds were crushed orange peel and ground black pepper. In spite of reduction in the physiological quality of stored seeds, the crashed orange peel was found to influence their quality.
