Biocontrol of , the Causal Agent of Coffee Leaf Rust, by sp. NMA1017.

Coffee leaf rust (CLR), caused by , is considered a highly important phytosanitary problem in Mexico. Currently, there are few microorganisms used as biocontrol alternatives to chemical control of CLR in organic coffee fields in Mexico. This study evaluates the use of sp.

Paenibacillus polymyxa NMA1017 as a potential biocontrol agent of Phytophthora tropicalis, causal agent of cacao black pod rot in Chiapas, Mexico.

Cacao represents an important source of income for farmers in the south of Mexico. However, phytosanitary problems have disrupted the production over the years. The use of antagonistic microorganisms as biocontrol agents might improve the production of cacao.
