There is severe flower and fruit drop...any suggestions??

Hi!! This symptoms may indicate a nutritional deficiency, such as Deficiência de NitrogênioNutrient deficiencies such as potassium, phosphorous, iron, maganese, zinc, boron, magnesium, copper and calcium occasionally affect plants. These deficienies usually occur in extremely acid or alkaline soils or where the topsoil has been removed by grading. Leaf and soil analysis can give you a great indication of what a particular plant needs, therefore, you will be able to obtain a more accurate fertilizer program.     

Symptoms are much similar to leaf blight. Spray with Curzate or Amistar for effective control.
