“…Black pepper plants parasitized by gall nematodes generally become chlorotic, with severe leaf yellowing, defoliation and reduction in chlorophyll content, which affects vegetative development, resulting in significant reduction in yield and even death (Freire & Monteiro, 1978;Ferraz & Lordello, 1989;Mohandas & Ramana, 1991). Some of these symptoms, such as yellowing, defoliation and roots with numerous galls were observed in the plants analyzed in our study.…”
