Abstract： To effectively control diseases and insect pests in sweet potato， variety comparison trials and pesticide screening experiments were conducted.The results of the variety comparison trials showed that‘Xigua Hong’and‘Jishu 26’exhibited vigorous growth，strong resistance to major diseases and pests，high yields，and a fine，sweet flavor. These characteristics make them suitable for large - scale demonstration and promotion in the Xi'an region. Pesticide screening results indicated that applying 1 kg per 667 m2 of Beauveria bassiana in the field achieved over 70% control efficacy against underground pests. This biocontrol agent is non - toxic， odorless，and environmentally safe，with a sustained infection capacity，allowing infected pests to continuously transmit the pathogen to others.
