Main Pests and Diseases in Tropical Forest Species in Nursery

Abstract

This paper presents the monitoring of pests and diseases in nurseries of 10 tropical forest species used in the reforestation of disturbed areas. The work was carried out in a rustic nursery established in Cardenas, Tabasco, under cocoa shade. The objective was to evaluate the presence of pests or diseases in the nursery under natural conditions. Pests and diseases appeared from the seedling stage in germination beds to the adult stage. The fungus Fusarium was the most aggressive causal agent that caused the death of seedling in the germination beds, as well as Curvularia lanata that massively affected Tabebuia rosea plants. Likewise, T. rosea is one of the species with the most reported pests, as well as Lantana camara. On the contrary, Hamelia patens Jacq (Coralillo) did not registered important pests during the monitoring in the nursery.
