Abstract

The present study aimed to (Ι) Determine the effect of cotton
seed bug infestation on yield and quality of okra seeds. (П) Evaluate
the efficacy of some treatments on reducing seed damage caused by
cotton seed bug. (III) Determine the effect of preventing the cotton
seed bug control at beginning of the pods dryness. To achieve these
goals, the behavior of viability of okra seeds was study under the three
methods of control cotton seed bug infestation. Treatment (1): floral
buds were bagged from beginning of its formation until beginning of
the pods dryness, treatment (2): floral buds were bagged from
beginning of its formation until beginning of the floral bud formation
to the completely pods dryness treatment (3): insecticide spraying
treatment on Balady "red" genotype. This study was carried out during
two successive seasons. Results showed significant differences
between number and weight of perfect seeds, number and weight of
damaged seeds, damaged seed percentage, seed germination
percentage, weight of 1000 seeds, crude fat and crude protein
percentage were significantly increased by the treatment (2). The
check treatment resulted in maximum number of damaged seed per
plant, highest weight of damaged seeds per plant and also highest
damaged seed percentage. In addition that, mass and density of seeds
(physical properties) were increased by treatment (2). Preventing the
cotton seed bug control at beginning of the pod dryness led to low
quality and quantity of okra seed yield.
