Abstract
The field experiments of the present study were carried out in two
localities: the Research Experimental Farm, Faculty of Agriculture, Saba Basha, Alexandria University and ltay El-Baroud Agricultural Research Station, Agricultural Research Center, El-Behira Governorate during the subsequent cotton seasons of 1999, 2000 and 2001. The objectives of this contributional study were initiated to evaluate the combined effects of some tested foliar nutrients, seed dressing by the bio-fertilizer-Microbin" and/or the animal hormone-Thyroxine besides, some the other alternative chemical compounds on the tolerancy of treated cotton plants to infestation with bollworms as well as yield characteristics.
The obtained results can be summarized as follows:
I. Effect of the evaluated foliar nutrients and alternative chemicals on the level of the pink bollworm infestation during the growing cotton seasons of 1999, 2000 and 2001.
I.A. Cotton season of 1999, Alexandria:
The application of tri-consequent foliar spraymgs of Baythroid" with Potasin-F and Greenzit N.P.K. completely prevented the occurrence of the pink bollworm infestation followed by Baythroido; with Greenzit S.P100 and Ascorbic acid (0.04 larvae!l 0 bolls), in comparison to the
untreated check (0.23 larvae!l 0 bolls). Contrarily, the hi-sequent
spraymgs of Neem and Agerin gave the highest level of the pink bollworm infestation (0.57 larvae/bolls). In other tested foliar treatments, the calculated mean numbers of inspected pink bollworm larvae were
