The data filed were obtained in the Protection Station of Yaguaramas about four the crops in the register of existent areas, stationary fields, journeys of itinerary, reports of seasons and historical territorial registration. It was analyzed the levels of incidence by varieties, sowing times or plantation according to meteorological variables.
