Excess telluric water

 (drowning , water wilt)


  • Susceptible botanical family(s)
All families


  • Production areas affected :
Mayotte Reunion Guyana
Guadeloupe Martinique New Caledonia
French Polynesia    


  • Organs attacked :
Ships Roots
  • Symptoms  :
    • browning and rotting of roots, decomposition of the cortex (figures 1);
    • sometimes more or less marked browning of the vessels located in the pivot and the lower part of the stem (figure 2);
    • more or less rapid withering (figure 3), yellowing (figures 4 to 6), even necrosis of the leaflets and/or the lower leaves of the plants;
    • reduced plant growth.
  • Cause(s) :
    • poor irrigation management;
    • heavy, hydromorphic soil or poorly draining substrate;
    • accumulation of water in poorly drained areas;
    • heavy rains or ruptures of irrigation pipes, during the deficiency of solenoid valves;
    • more or less important submersion of the culture, etc.
  • Diagnostic clues :
    • the plants affected are often distributed over the whole of the plot, or in certain zones or on certain rows;
    • the plot is poorly drained, the soil is rather heavy;
    • the soil or substrate seems rather saturated with water (don't hesitate to see it for yourself);
    • control the quality of plant irrigation (mode, frequency, efficiency);
    • control the recent climatology (significant rainfall).


  • Possible confusion : root parasitic microorganisms and pests, etc.


  • Remedies :
    • drain the soil ;
    • be wary of certain rather asphyxiating substrates;
    • adjust the frequency and quantities of water applied to each irrigation ;
    • bury the plants so that they can produce new roots (option valid only for species with significant root regeneration capacities).
