Abstract:

Under conditions of zero nutrition edáfica and limited contribution of water in banana tree, you carries out the experiment in the Property it USES in the road to Pajonal to five km of the city of Machala to prove the organic fungicide Diss 4x4, associated with nutritious foliares. The used nutrients were the following ones: Fertipac and Krystalon of relationships 1:3, with contained NK 120-360; 130-400 respectively, Combiplus of relationship 1:3 and contained NK 40-120, Diss energy of relationship 1:0,63.
