| Abstract | ||||
| Three field experiments were conducted during the season 2006, at the private farm at Nubaria region: the first trial included releasing the predatory mite Phytoseiulus persimilis (A.-H.) with rate of 15-20 mites / hill. While the other trials included evaluation of some environmentally safe materials and study the effect of different fertilizers adding in different ways on spider mites population. Obtained results cleared that the predatory mite P. Persimilis minimizing the spider mites population 72.8% after 9 weeks of releasing and the infestation level was under threshold level during the season .The environmental safe compounds indicated that mixture of Vertimec and Super-misrona mineral oil exhibited the highest reduction (91.4%) followed by Vertemic (87.5%), mineral oil (72.9%), Oshar extract (58.4%), Enab El- Deab extract (54.6%) and Bioranza (53.6%).Foliar application of KP and micro- elements reduced the mite population (52.8 and 50.7 %) while soil spray bacteria solubility of potassium and phosphorus gave (43.7 and 12.9 %) ,respectively. It's cleared that different fertilizes were minemized the number of mites and also they improved plant health and crop yield. | ||||
