This research is to evaluate chemical and organic products for the control of pink disease Corticium salmonicolor in a rubber cultivation Hevea brasiliensis, at Chitalón, S.A. Farm, as part of the Supervised Professional Practice of Tropical Agronomy career. The research was conducted in the Chitaloncito section, starting on April 17th 2,015 and ending on September 18th 2,015. To the effect 11 applications and 12 samples were made to establish the behavior of the response variable "percentage of severity of the fungus Corticium salmonicolor "at intervals of fifteen days; the treatments under study were two organic fungicides (Allium and Penazyme) and two chemicals fungicides (Triamyl and Bayfidan). The experimental material consisted of a rubber plantation of five years old of clone RRIM-600 (81%) and clone PB-260 (19%). The Plantation is in association with coffee cultivation Coffea arabica and woody plants; the selection of the experimental area was to take trees with the fungus C. salmonicolor, in the range of 80 to 100 percent, to evaluate the effectiveness of the fungicides in study.
