Integrated evaluation of synthetic and botanical insecticides for the management of whitefly (Bemisia tabaci) nymph populations on tomato and sweet potato under plastic house condition

Abstract

Generally, Whiteflies (Bemisia tabaci G.) is considered as one of the most wide important problems protected vegetable production systems. It affects plants directly and indirectly, leading to lesser output, its value and quantity of harvest. The first one evaluates the effectiveness of the three synthetic insecticides (Citaprid 20 WP, Evizil 50% SP, and Oberon 240 SC) on tomatoes in a greenhouse, while the second one is in vitro experiment include the evaluation the effect of three dosages of ginger (%10, %15 and %20) and garlic extracts (%10, %15 and %20) against whitefly nymphs on sweet potatoes. We used random complete block design statistical analyses, ANOVA, LSD, and Duncan's test for these experiments. The obiron and 20% ginger extract were Superior in their effectiveness in, killing 77.33% and 85.5% respectively. These results support a number of the views of integrated pest management (IPM) and indicating the importance of a variety of chemical and plant procedures to control whiteflies well for prolonged periods. Using this combination can mitigate chemical resistance, save the planet, and contribute to more sustainable agriculture at a macro level globally. Importantly, using this smart combination of Oberon with 20% ginger extract can effectively mitigate development of chemical resistance in whitefly populations, help save the planet from excessive pesticide pollution, and contribute meaningfully to more sustainable agriculture practices at a macro level globally across all regions.
