This study aims to assess the incidence of pests and diseases in citrus trees, the use of plant protection products (PPPs), and farmers' willingness to adopt nano-formulated products for disease management. A survey of 30 citrus-growing households in Quang Binh and Bac Quang districts revealed that citrus trees are affected by 14 pest species and 8 major diseases, with their occurrence varying by orchard age and time. Disease incidence resulted in significantly greater yield losses than pest damage, with reductions of 19.4-27.1% and 2.2-4.1%, respectively. All 100% of households reported using chemical PPPs for pest and disease control due to their affordability and rapid effectiveness. However, 56.67% of respondents were unaware of potential health risks, and 73.33% did not recognize the environmental impact of chemical PPPs. The willingness to adopt nano-formulated products for disease management remains low, with only 67.67% of respondents expressing interest.
