Use of magnetize water to control some cowpea, (Vigna unguiculata L.) pests

Walaa Tawfik A, Abdel-Salam AH, Hala EM, El-Meuafy and Ola M Roshdy

Semi field experiments were conducted to determine effect of different magnetized water concentrations on the population of cowpea pests, Aphis cracivora Koch, Empoasca decipiens Paoli and Bemisia tabaci Gennadius. Investigation and recording results were carried out 1, 3, 5 and 7 days after treatments. Results reported that there was a clear and significant effect for the magnetism to decrease and minimize Aphis cracivora. The total mortality was 32.47, 48.47 and 66.86% when treatment with magnetic seawater in concentrations 10, 20 and 40 milli-tesla. While, the total mortality for Bemisia tabaci was 14.99, 29.99 and 34.36%. Meanwhile, the efficacy of magnetized water had a strong repellant effect compared with its mortality percentages on Empoasca decipiens.
