Dataset supporting the manuscript: Efficacy of Biorational Products for Managing Diamondback Moth (Plutella xylostella) in Cauliflower

This dataset contains the square-root transformed observations [√(x + 0.5)] of diamondback moth (Plutella xylostella L.) larvae recorded from cauliflower during field experiments conducted at Rampur, Chitwan, Nepal in 2020. The experiment was conducted using a Randomized Complete Block Design (RCBD) with six treatments and three replications. The dataset includes observations collected after the first, second, and third spray applications at four observation times: before spray, 3 days after spraying (3 DAS), 6 days after spraying (6 DAS), and 9 days after spraying (9 DAS). The Excel workbook contains separate worksheets for the first, second, and third sprays, along with treatment codes and metadata. This dataset supports the analyses and findings reported in the associated manuscript on the management of diamondback moth in cauliflower.
