Abstract

Pepper (Capsicum annuum) is an important crop in Peru and is negatively affected by the knot nematode. This studio’s objective is to evaluate the reaction of three pepper varieties (Papri King, Papri Queen, and Bell pepper cv. ‘Yolo Wonder’) to Meloidogyne arenaria, M. incognita, and M. hapla. The experimental design was completely randomized into three pepper varieties and three Meloidogyne spp. with six replicates. The peppers were maintained in a plastic shade house, cultivated in polyethylene bags with 4 kg of sterilized sand, which were inoculated with 5000 eggs and juveniles (J2). At 90 days after inoculation, leaf height (LH), root length (RL), dry leaf weight (DLW), fresh root weight (FRW), chlorophyll index (SPAD), root gall index (RGI), and reproduction factor (RF) were evaluated. The results showed that all pepper varieties were susceptible to M. incognita, M. arenaria, and M. hapla. LH, RL, DLW, FRW, and SPAD all indicated a decrease in pepper growth and development, with the highest reduction, observed in the presence of M. incognita, followed by M. arenaria and M. hapla.
