Shallot production in Indonesia was 10.72 million tons, of which Bima Regency had the highest production in West Nusa Tenggara. The research data in the figure and table is secondary data obtained through the Central Statistics Agency website and the Food and Agriculture Organization Corporate Statistical Database, and photo documentation of shallots attacked by pests and diseases was taken in June 2020 in Risa village, Bima Regency, West Nusa Tenggara. The most challenges for shallot producers are the presence of pest and diseases such as Spodoptera exigua, Alternaria porri, and Fusarium oxysporum which affect production, harvesting, processing, and marketing stages, which lower the quality, reduce yield, and increase the cost of production. The effects of pests and diseases can be lessened through various cultural, mechanical, chemical, and biological controls as integrated pest management.
