Nowadays the use of microorganisms in agricultura is one of the alternativa solutions to reduce the use of chemicals products. The arbuscular mycorrhizal fungi (AMF) are soil fungi, which form mutualistic symbiosis with the roots of most plants, including the coffee, providing excellent benefits. The objective of this research was to determine the effect of different sources of inoculum of nativa AMF on root-knot nematode (Meloidogyne spp.) in coffee seedlings (Coffea arabica) variety caturra in the region San Martin. lt was used a completely randomized design (CRD) with 11 treatments (9 inoculum sources of native AMF + 2 witnesses) and 3 repetitions. To determine the antagonistic effect between these two organisms, 1500 spores were inoculated per plant of each one of the different sources of inoculum using a sterile substrate and after 140 days each plant were infested with 2000 eggs + ...
