Abstract

Soil suppressiveness could be considered as the central concept emerging from community level in regard to soil-borne diseases in agroecosystems. In this paper the nature of soil suppressiveness is described as well as some research conducted in Mexico characterizing suppressive soils and the induction of such property in conducive soils.The induction of soil suppressiveness to Phytophthora cinnamomi in avocado groves that yielded the so called Colegio de Postgraduados integrated management system is also described. The emergence of soil suppressiveness to corn root diseases under tropical conditions through the rotation with the tropical legume Mucuna deeringiana is also described and an account is made of the establishment of ascendant complexity of antagonistic (to plant pathogens) microorganisms isolated from suppressive soils to protect tomato plantlets to some root pathogens. Finally, some perspectives are set forward for future research on the subject in Mexico.
