An approach for IPM program to control sucking pests infesting garden bean plants (Phaseolus vulgaris L.) in Egypt.
An approach to eatablish IPM program for some sucking pests infesting garden beans plants was carried out in two successive seasons of 2004 and 2005 under field conditions in Alexandria, Egypt. The sucking pests included the aphid, Aphis craccivora Koch (Homoptera: Aphididae), the white fly, Bemisia tabaci Genn. (Homoptera: Aleyroidae) and the spider mite, Tetranychus urticae Koch Pymetrozine, thiamethoxam, carbosulfan, abamectin, azadirachtin and the detergent (Masrol 410) were tested for their efficacy in this study. Thiamethoxam, carbosulfan, and pymetrozine proved to be highly effective against Aphis craccivora Koch, while abamectin, azadirachtin, and the detergent (Masrol 410) provided a moderate effect. Moreover, thiamethoxam, pymetrozine, and abamectin showed remarkable efficacy against adults and immature stages of the whitefly, Bemisia tabaci. However, azadirachtin provided a moderate effect, while carbosulfan and detergent (Masrol 410) had no effect altogether on whiteflies. In addition, abamectin induced the highest toxicity effect against the red spider mite, Teteranychus urticae followed by azadirachtin and the detergent that provided moderate effects. IPM program could be achieved by using abamectin, pymetrozine and azadirachtin in a sequence pattern throughout the whole season. Furthermore, the performance of the used agrochemicals on certain nutritional elements of beans pods vr. Branco , i.e. nitrogen, phosphorus, potassium, iron, and magnesium were also studied with varied results.
