Sugar beet cultivation has gained prominence as a viable alternative to sugarcane in regions where climatic conditions are less favorable for sugarcane growth. This study, conducted at Barangay Paagahan, Mabitac, Laguna, aimed to evaluate the efficacy of Kakawate (Gliricidia sepium) and Acapulco (Cassia alata) leaf extracts as biopesticides for managing pests in sugar beet (Beta vulgaris). A single-factorial experiment was employed with five treatments, laid out in a Randomized Complete Block Design (RCBD), and replicated across four blocks. The treatments included T1—Control (no biopesticide), T2—Commercial pesticide, T3—Kakawate extract, T4—Acapulco extract, and T5—50% Kakawate + 50% Acapulco. A total of 1,600 sugar beet plants were planted in the experimental area. Our results indicated that Treatment 5 (50% Kakawate and 50% Acapulco) was the most effective, leading to the highest economic yield and heaviest plants. Treatment 3 (Kakawate) produced the longest roots and tallest plants, while Treatment 4 (Acapulco) resulted in the largest root diameter. Furthermore, sugar beets treated with Kakawate and Acapulco were preferred for their appearance, taste, and overall acceptability. Treatment 5 also generated the highest net income (9,000 pesos). These findings suggest that Kakawate and Acapulco leaf extracts are promising, eco-friendly biopesticides for sugar beet pest control, offering potential for sustainable pest management strategies. Further research is recommended to assess their long-term sustainability and explore additional complementary pest control methods.
