The Central Plantation Crops Research Institute (CPCRI) is working on developing tissue-cultured disease-resistant areca nut plants to combat Yellow Leaf Disease, a problem that has affected areca palms since 1914. The institute has collected inflorescence from disease-resistant palms to reproduce and cross with other disease-free palms. The project's initial stage involves gathering samples from various palms and transferring them to labs for testing. Yellow Leaf Disease is spread by the plant-hopper insect, Proutista moesta, and causes areca palms to yield less due to the illness affecting plants of all ages.
