Analysis of biological organic extract of plants in suppressing aphid (Myzus persicae) infestations

Myzus persicae commonly known as the peach-potato aphid, poses a significant threat to agricultural productivity, particularly in potato cultivation, where infestations lead to substantial yield losses and quality degradation. In this study, we investigated the potential of botanical extracts from neem (Azadirachta indica), clove (Syzygium aromaticum), black pepper (Piper nigrum), and bay leaf (Laurus nobilis) in controlling Myzus persicae infestations. Experimental trials were conducted to assess the mortality effects of these botanical extracts on Myzus persicae populations. Results revealed that neem extract exhibited the highest mortality effect, with an impressive 97.7% mortality rate. Clove and black pepper extracts followed closely, demonstrating mortality rates of 92.2% and 77.7%, respectively. In contrast, bay leaf extract exhibited the least mortality effect, with only 48.8% mortality observed.
