In intensive agriculture as an immediate measure to plant pathogens and poor nutritional soil fertility, they often use pesticides and chemical fertilizers. These are considered highly dangerous and toxic to human health, soil biology and the environment. In addition, consumer demands interested in safety, leads to dabble in the study and development of clean technologies such as biological control alternatives and partner agencies based plants as growth promoters microorganisms (PGPR) fertilizer and mycorrhizal fungi. These are considered as important beneficial rhizosphere microorganisms and can be used as biological control strategy against certain root pathogens such as nematodes. The objective of this research was to use growth promoting microorganisms and endomycorrhizal fungi to control the spread of nematodes, improving quality and crop production aguaymanto (Physalis peruviana L.). This work has identified the Meloidogyne incognita, as a pathogen in growing Physalis peruviana (aguaymanto). It also has studied the relationship between initial nematode population and development in the fresh weight of the plant and root determining the degree of severity, the number of eggs and juveniles 5000 between second stage of M. incognita per kg substrate with which the plant is affected in its development. The results of the in vitro and in greenhouse tests showed that the strains of bacteria diazotrophic Azo16M2 and DA30 had the highest percentage of capacity to inhibit M. incognita as well as the use of these strains increased the percentage of mycorrhizal colonization (CM%) as in the number of spores per gram of dry soil (No. spores / g dry soil). Treatments where interactions endomycorrhizal used with diazotrophic strain (strain DA30 or Azo16M2) presented in most of the measured parameters, greater control over the development of plants infected with the nematode, thus could be recommended as alternative to reduce the use of nematicides.
