| Abstract | ||
| This study was conducted during the restricted period which started from the middle of June of each of 2006 and 2007 at Belbeis district, Shakia Governorate to investigate the Protective Potential of certain Pesticides to grapes from house sparrow, Passer domesticus ni/oticus attack. Four chemical Pesticides namely, Bayfidan, Pyriban, Cidial L and Captan, were used. Two bird mechanical management means namely, nest destruction and Reflecting stripes were also tested. Results showed that the tested pesticides at 0.5% and 1.0% concentration achieved quite protection for seedless grape against house sparrows compared to check treatment The degree of protection was related to increasing the level of application. The high repellency effect against the house sparrow was occurred by Bayfidan and Captan during second season while the same results were realized by Bayfidan and Pyriban during first season. Also, the gained figures assured that Nest destruction and reflection strips gave a great protection against house sparrow. Reflection strips as bird scaring was preferable than nest destruction in protecting the seedless grape from the birds. The effect of two used concentrations (0.5% and 1.0%) of the four tested pesticides on grape fruits. The whole pesticides induced a considerable increase in rate of changing in weight and in both long (L) and short (S) diameter of berries grape during two seasons. In addition, Cidial L gave the highest rate of changing for each of soluble solids and acidity and the lowest figures was recorded in case of Bayfidan at 1.0% concentration. | ||
