The state of Pará is responsible for 80% of the national black pepper production, and Brazil is the third biggest producer and exporter of the spice. However, the production and productivity of the culture has been decreasing throughout the years due to the occurrence of the root rotting disease caused by Fusarium solani f sp. Piperis in a great number of black pepper farms, leading to great economical loss and substantial decline in plantation area along the period of more than forty ye ...

Black pepper ( Piper nigrum L.) is highly important in Brazilian agri-business, and it currently occupies the fourth position in the world's market export rates, the state of Pará being responsible for 85% of the national production. In this context, the emergence of fusariosis, caused by the Fusarium solani f. sp. Piperis fungus, has been the source of significant losses to the black pepper culture, especially in Pará. Studies have confirmed the narrow genetic base and the suscep ...

Brazil is the fourth main world producer and exporter of black pepper, having had an estimated production of 33,000 tons in 2008. It is an important agricultural product to Pará's exporting schedules, being responsible for almost 90% of the entire country's production. The fusariosis disease caused by the Fusarium solani f. sp. Piperis fungus is the main cause for reduction of production cycles and increase in production costs. Once the disease is detected, the area is completely devasta ...

The culture of black pepper ( Piper nigrum L.) is of great socio-economical importance in the northern states of Brazil, Pará especially. However, its production has been suffering the incidence of diseases such as the one caused by the Cucumber mosaic virus(CMV) and the Piper yellow mottle virs (PYMoV). Although these viruses have already been reported in many of the Brazilian states, there are too few studies that address the virus diseases which affect this culture. Hence, this project ...
