Microneedles, which are small needle-shaped devices, have gained attention as versatile tools with applications acrossvarious fields owing to their precision and minimal invasiveness. In the literature, the integration of microneedle technology intoagricultural domains has been explored, particularly focusing on the real-time monitoring of precise agrochemical delivery and cropbiosensing in situ. In this study, we summarize representative microneedle types and corresponding fabrication techniques. Then, wediscuss the advantages of microneedles in plant health management and drug delivery, as well as related challenges, such as safetyand mass production. The agricultural applications of microneedles can potentially overcome the limitations of traditional methodsand offer innovative solutions for crop disease management. This study demonstrates that microneedles present innovativepossibilities in agriculture and contribute to the improvement of sustainable agriculture.
