Abstract: Plant-derived insecticides were found to be useful for controlling insects infestation in storage without any adverse effect on seed viability. The objective of the present study was to determine the efficiency of spraying extracts of plant-derived insecticides namely neem kernel and black pepper in addition to a recommended application of Malathion-57% at flowering and seed setting stages on seed viability, seedling vigour, insect infestation and seed weight loss and its chemical composition (protein, carbohydrates) during storage of 0, 6, 12, 18 months.
Two field experiments were carried out at Tag El-Eizz Agricultural Research Station, Agricultural Research Center (ARC), during 2002/2003 and 2003/2004. While storage studied were conducted at Seed Technology Research Section, Giza under normal conditions during 30 June 2003 till December 2005. The results revealed that there was a gradual reduction in seed viability as measured by seed germination, seedling vigor and a gradual increase in insect infestation loss of seed weight.
The reduction was related to the applied insecticide and storage period. Malathion-57%, ethanol extracts of neem kernel and black pepper, respectively were more efficient compared with the control.
Prolonging storage period increased loss of weight, protein content and insect infestation levels, whereas increasing of storage period till 18 months slightly decreased seed germination, seedling vigour and carbohydrate percentage. Seeds of the variety Giza 3 were more resistant to insect infestation than Giza 2 and Sakha 1, respectively. The results suggest that spraying ethanol extracts of neem kernel and black pepper at flowering and seed setting stages as an alternative approach of using Malathion-57% before storage to keep quality of faba bean seed and for controlling insect infestation for 18 months
