Abstract
Field experiments were conducted during 2020 and 2021 to evaluate the efficacy of homemade neem extract @ 3000, 4000 and 5000 ml along with standard insecticide imidacloprid 17.8 SL @ 100 ml (standard check)/ ha against jassid Amrasca biguttula biguttula in okra at the Punjab Agricultural University Regional Research Station, Gurdaspur and farmer’s field at Marianwala (Batala), Punjab. The results revealed that all insecticidal treatments were very effective. Imidacloprid 17.8SL proved superior and gave maximum fruit yield followed by higher and median dose of homemade neem extract. The highest cost benefit ratio (Rs. 1: 75.74) was achieved with highest dose of homemade neem extract and closely followed by imidacloprid 17.8 SL (Rs. 1: 50.74). These were also found very safe towards predators (spider and coccinellid)
