Abstract:
... In Africa, peri-urban vegetable production systems supply perishable vegetables to the rapidly expanding urban centers. These highly intensive systems are characterized by high levels of pests and diseases and an excessive use of synthetic pesticides to reduce their population densities. Root-knot nematodes (RKN) are especially prevalent in these systems but are often not recognized, or diagnosed ...

Abstract:
... Meloidogyne enterolobii (the guava root-knot nematode) is a highly polyphagous species that causes significant damage in a wide variety of crops worldwide (Castagnone-Sereno 2012). M. enterolobii has a well-documented ability to overcome many crop resistance genes that are effective against the more cosmopolitan M. incognita group (MIG) species endemic to the southern United States. In the contine ...
