Tomato (Solanum lycopersicum) production faces significant threats from whiteflies (Bemisia tabaci), which transmit Tomato Leaf Curl Virus (TLCV), causing severe yield losses of up to 100% causing economic hardships for farmers. Conventional management relies on synthetic pesticides, which pose environmental risks, contribute to pest resistance, and negatively impact beneficial organisms. This study evaluates the efficacy of botanical extracts in managing whitefly populations and mitigating TLCV infections as a sustainable alternative to chemical pesticides. A randomized complete block design (RCBD) was used to assess the effects of neem (Azadirachta indica), tithonia (Tithonia diversifolia), and datura (Datura stramonium) extracts, alongside an untreated control. Botanical extracts were applied as foliar sprays at a 1:3 dilution ratio, with weekly observations on whitefly abundance, disease incidence, and severity. Disease severity was evaluated using a scale ranging from 0 to 5. Data were analyzed using Analysis of Variance (ANOVA), and mean separation was conducted using Fisher’s protected Least Significant Difference (LSD) test at p<0.05. Results showed neem extract was the most effective botanical treatment, significantly reducing whitefly populations and disease severity. Plants treated with neem exhibited the lowest disease incidence, reinforcing its strong pesticidal and antiviral properties. The study highlights neem extract as a viable alternative to synthetic pesticides, promoting eco-friendly agricultural practices while enhancing tomato yield and quality.
