A New Biological Product Shows Promising Control of the Northern Root-Knot Nematode, <i>Meloidogyne hapla</i>, in Greenhouse Tomatoes

Abstract Tomato plants are susceptible to significant yield losses when infested by the northern root-knot nematode, Meloidogyne hapla. While there many options for conventional chemical management, few of these offer effective control organic growers or those who seek adopt more environmentally considerate strategies. In this study, we showed that a new, biologically based product (referred as “MN21.2”) has potential controlling populations hapla , pest tomato (cv. Rutgers) in greenhouse trial. This is because if product’s efficacy supported under field conditions, it may provide with valuable tool fighting plant-parasitic nematode pest, M.
