| This study was conducted to test the effectiveness of some plant extracts and factor biotic resistance Trichoderma harzianum single way or integrated with each other in reducing white mold disease on eggplant Caused by a fungus Sclerotinia sclerotiarum, where this study was conducted in two phases included the first phase of laboratory study to determine the preference of some kinds of plant extracts in reducing the spread of the disease, which was conducted in the laboratories of Pharmaceutical Samarra / Department Almaekerobailogi, while included the second phase of testing plant extracts that have proven effective in vitro study with biotic resistance factor Trichoderma harzianum individually or integrated with each other, was conducted this experiment in greenhouses of the Department of protection/ College of Agriculture / University of Tikrit agricultural season 2013-2014.

Demonstrated field results conducted under the conditions of greenhouses on the crop eggplant that the treatment of garlic extract with bio-resistance factor has achieved encouraging results in reducing the incidence and severity of reaching a rate of (26.64, 5.70%), respectively, with a note no significant differences between the treatment of the extract garlic alone, which amounted to (28.86, 5.80%), respectively, the study on the characteristics of shoot and root growth showed that the treatment of garlic extract with bio-resistance factor has led to an increase in fresh and dry weight of shoot and root compared with other transactions where was wet and the dry weight of grouped shoot and root (668, 158.3, 191.3, 73.3) g, respectively. | ||
