| Abstract | ||
| An experiment was conducted in lab. of Hort. Dept. of Agricultre College / Univ. of AL-Qasim Green from 20-3-2015 to 5-4-2015 to determination the effeciency of aqueous plant extracts Citrus sinensis, Citrus limonum, Clerodendron inerme, Capsicum annuum, Mirabilis jalapa, Datura stramonium, Nicotiana tobaccum L, Zingiber officinale, Allium sativum and Allium cepa in concentrations( 0.5, 1, 1.5 g liter) and also used the fungal extract Beauveria bassiana with plant extracts in the evaluation of its efficiency to control the green peach aphid Myzus persica on the pepper plant. Results showed that the highest percentage of the mortality of adult of M. persica after three days of treatment was the concentration of 1.5 g liters of aqueous extracts of M. jalapa plant reaching 100% when compared with other plant extracts. While less extracts influential is the C. sinensis and C. limonum extract reaching the percentage of mortality stood at 8.3% after 15 days of treatment and all transactions significant differences comparison with the treatment control. The results also showed that the mortality rates reached 100% for the two concentration 1.00 and 1.5 g liter after 6 days of treatment of aqueous extracts of each of C. annuum, M. jalapa, Z. officinale, A. sativum, A. cepa, respectively. The results also showed that the percentages of mortality of dilution spores fungus B. bassiana in M. persica were less than 50% after 10 days of the treatment, while the mortality percentage rate Increased after 15 days to reached 95% to the dilution 101- spore / ml, while the rate reached 78.35% to dilution 102- spore / ml. | ||
