Presencia y parasitismo de Pratylenchus zeae en caña de azúcar en Panamá con indicaciones sobre la susceptibilidad relativa de algunos cultivares

Single sugar cane plants ev. D-4502 were greenbonse-groun in 20-cm plastic pots with soil inoculated with 0, 19, 26, 54 and 109 Pratylenchus zeae per 50 cc soil After 6 weeks, a highly significant negative correlation between initial population of P. zeae and dry weight of tops was ford. Top weight...
