This flaccidity sympton appears like the "wilting" caused in plants under conditions of water stress. There is evidence to show that the disease symptom occurs in all soil types and seasons and also under water-logged conditions (Anonymous, 1981). Root (wilt) is a non-lethal disease, but debilitating in nature.  aCocos Nucifera  aCoconut  aCoqueiro  aPalms  aRoot disease  aStomatal resistance1 aPATIL, K.
