Effect of gibberellic acid on the persistance of certain pesticides onion grape fruits
2010
Ahmed, N.S. | Zidan, Z.H. | El-Sayed, W. | Abdel-Hamid, R.M.
Recommended application was done by spray regime for two pesticides, namely diniconazole, fenitrothion and a plant growth regulator (gibberellic acid) and their mixtures. Their residues were determined after different successive treatments in and on grape fruits in two consecutive years. The initial deposits of the fungicide diniconazole when used alone were 0.49 and 0.50 ppm for 2006 and 2007, respectively. While the initial deposits of fenitrothion reached to 11.35 and 11.19 ppm for the same interval, respectively. Initial deposits of the plant growth regulator gibberellic acid were 30.52 and 30.42 ppm for the same period, respectively. After mixing the tested pesticides and the plant growth regulator, the initial deposits loss reached 38.77 and 42.0 % for diniconazole, 43.08 and 48.16 % for fenitrothion and 6.88 and 7.00 % for gibberellic acid for the same seasons, respectively. A significant degradation was recorded with the mixture of the two tested pesticides and plant growth regulator compared with that occurred when pesticide was used alone at' the two studied seasons.

The present investigation was carried out during two successive seasons of 2002 and 2003 on Canino Apricot trees budded on seedlings rootstock at a private orchard located at El-Khatatba district, Menofia Governorate Egypt. Trees were sprayed at full-bloom stage with boron, GA3 and active dry yeast at different concentration alone or in their combinations. Results showed that spraying Boron, GA3 and active dry yeast either singly or in combination caused a remarked promotion in leaf min-eral status, yield and fruit quality compared with control treatment Combined appli-cation solution of 400ppm Boric acid, 40ppm GA3 and 2% active dry yeast at full bloom stage gave the best results with regard to the yield and fruit quality of Canino Apricot.
