Abstract: This experiment was conducted in the okra field at Gauradaha Agriculture Campus in Jhapa District, between March to June 2023 to evaluate eco-friendly practices through different treatments against jassid (Amrasca biguttula biguttula) in okra. The layout was carried out to fit the experiment into Randomized Complete Block Design (RCBD) with 7 treatments and 3 replications using a variety Arka Anamika. The treatments were: Agri-spray oil 99% EC (4 ml/ltr), Cow-urine (200ml/ltr), Neem oil (2ml/ltr), Tobacco (200 ml/ltr), Eucalyptus (200 ml/ltr), Mugwort (200ml/ltr) and Control with water spray. Treatments were applied 3 times using a foliar spray method. Following 3 sprays, observations were made on each spray on the 2nd, 4th and 6th days of application. Highest Population Reduction over Control (PROC) i.e. 74.27%, 38.62% and 36.36% of jassids was found in first, second and third spray of agri-spray oil followed by tobacco i.e. 62.57%, 31.21%, 37.45% and neem oil i.e. 59.69%, 23.47%, 20.97% respectively and was found to be significant in each three sprays of treatments. Based on overall performance, agri-spray oil performed better by reducing the pest population and producing highest yield.Among botanicals, tobacco was found to be superior for controlling pests. Therefore, the application of eco-friendly pesticides can reduce the use of synthetic pesticides that are costly and possess a large toxicity to natural enemies and negative impact on human health and environment.
