Abstract

The use of alternative ways to control pests and diseases in agriculture is becoming increasingly popular, as they are methods that do not cause a negative impact on the environment, unlike chemical pesticides. This research aimed to evaluate antagonistic plants (sorghum, crotalaria, mucuna, guandu bean and neem) in reducing the infestation of Meloidogyne javanica and M. enterolobi. The experiment was conducted in a greenhouse belonging to the Federal Institute of Ceará – Campus Sobral, from May 17 to July 2, 2013. Five plant species, sorghum, crotalaria, mucuna, guandu bean and neem were used. Nematodes142.94 g of each fresh plant was mixed with soil infested with nematodes in plastic pots of 1 liter capacity, and the experimental design was randomized, EDR. The most promising results were observed in the neem and sorghum plants, in which the most significant variables for both species of nematode reductions were observed, highlighting the number of galls per root system and per gram of root. It is concluded that the control of these plant-parasitic nematodes through the use of neem and sorghum can be effective.
