Field Evaluation of Some Botanical Extracts against the Pea aphid Acrythosiphon pisum (Homoptera: Aphididae) on Field pea Pisum sativum L

Dagne Kora, Ermias Teshome

Green pea aphids (Acrythosiphon pisum) are among the most important pests challenging Field pea production. Although there are some insecticides, cost and environmental hazard necessitates the development of safe and effective management options. With this intent Aqua’s extract of Chilli, Garlic, Ginger and Mexican marigold were evaluated for their insecticidal property. ANOVA for after spray aphid count depicted that there was significant difference (P<0.005) between treatments. The maximum number of aphids/plant (7) was recorded from untreated check while the minimum (0) was from Chilli, Ginger and Mexican marigold treated plots. Similarly, grain yield ANOVA has revealed significant differences (P<0.05) between treatments; the highest grain yield (2511.3kg/ha) and the lowest (1846kg/ha) was obtained from Mexican marigold and chili treated plots, respectively. This result depicted that Mexican marigold was the most effective botanical insecticide against pea aphids. Therefore, foliar sprays of Mexican marigold is recommended at a rate of 4 kg/ha.
