Abstract
The study was conducted to check the response of major insect pests of potato towards plant extracts and a synthetic insecticide and their effect on yield of potato crop at district swat, during 2023. Six treatments including control, four different botanicals and a synthetic insecticide i.e. T1 (Neem seed extract), T2 (Fresh red chili extract), T3 (Moringa leaf extract), T4 (Chinaberry fruits extract), T5 (Chlorpyrifos 40% EC) and T6 (Control) were used. Plant extracts were applied at 10% each while chlorpyrifos was applied at recommended dose. The outcomes revealed that after the application of 1st and 2nd spray the lowest mean number of aphids population plant‐1 were observed in the plot treated with chlorpyrifos (4.76 and 1.68) whereas in plant extracts moringa leaf extract was found to be the most effective with (6.23 and 3.51) mean aphids population plant‐1, subsequently followed by chinaberry fruit extract (7.04 and 4.54), red chilli extract (7.46 and 5.12), neem seed extract (7.73 and 5.65) and the highest mean number for aphid population plant‐1 was recorded from control plot (8.53 and 7.26). Similarly after the 1st and 2nd application of treatments against jassids, minimum jassid population was recorded for plots treated with Chlorpyrifos (5.26 and 2.23), while in plant extracts plots treated with moringa leaf extract revealed minimum jassid population plant‐1 (6.86 and 3.90), followed by chinaberry fruit extract (7.80 and 5.47), red chilli extract (8.50 and 6.16), neem seed extract (8.81 and 6.80) number of jassids population plant‐1 were recorded. The plot treated with chlorpyrifos has shown highest yield (12859 kg/ha) followed by moringa leaf extract with (10840 kg/ha), chinaberry fruit extract (9181 kg/ha) and the minimum yield (6171 kg/ha) was observed for control plot. Highest cost benefit ratio (1:53) was observed for Chlorpyrifos treated plots followed by moringa leaf extract (1:46), chinaberry fruit extract (1:32) and red chili extract (1:26) and lowest CBR was recorded for neem seed extract (1:17). Based on the above findings it is concluded that among plant extracts moringa leaf extract and chinaberry fruit extract was the most effective against the population of the above mentioned pest and subsequently increases crop yield. Therefore it is recommended to use moringa leaf extract in future IPM strategies for the effective management of aphids, jassids population and to enhance yield.
