In Haiti, the presence of the various rice diseases in the fields, the yield losses caused by them and the control mechanisms have been very little studied. During the period from June to October 2019, a study was carried out in Saint-Marc, more precisely in Bocozelle in the locality of “DEZIRE”, in order to study the behavior of four local rice varieties against the attack of certain fungal diseases in natural conditions in two different rice-growing systems (IRS: Intensive Rice Growing System; TRS: Traditional Rice Growing System). In addition to the diseases identified during the experiment (blast, helminthosporiosis, panicle leaf sheath rot: certified present in Haiti by MARNDR), the study revealed the presence of curvulariasis spores at the leaf surface.

Intercropping is the main farming method practiced in Haiti. It occupies more than 65% of the useful agricultural areas, with the dominance of cereals (maize, sorghum), cultivated mainly with legumes such as the cowpea. Poor farming practices is one of the main constraints encountered in this system, especially in terms of densities. The plants are grown at low seed densities, so finding an optimum density that promotes better yields is difficult.
