Abstract

Soybean (Glycine max L.) has received special attention all over the world because of the great nutritive and oil values of its seeds. The spider mite, Tetranychus urticae Koch considered one of the main pests, which threatens the soybean crop yield. Three field experiments were conducted during the season, 2017 at Kafriklaa, El-Santta district, Gharbia Governorate, to evaluate some environmentally safe materials; some plant extracts and the efficiency of the predatory mite, Phytoseiulus persimilis (A.-H.) in controlling the two spotted spider mite, T. urticae infesting soybean. Obtained results showed that mixture of Vertimec + Super-Misrona oil exhibited the highest reduction (94.4%) followed by Vertimec + Micro-elements (92.2%), Vertimec alone (88.55%), Super-Misrona oil + Micro-elements (78.2%), Super-Misrona alone (75.4%) and Liquid-Sulphur (70.8%).      The efficacy of the three plant extracts could be arranged in a descending order as follows: 68.7, 62.7 and 57.2% for Oshar (Calotropis procera Ait), Black shadenight (Solanium nigrium L.) Unrip- fruit and Neem (Azadirachta indica A. Juss) extracts. The third trail was releasing the predatory mite, P. persimilis with rate of 15-20 mites/hill during seedling stage of soybean plants and the level infestation 3-5 mites/plant. The population of spider mites reduces 71.5% after 8 weeks of releasing and the level of  infestation had become under threshold for the end of season.
