ABSTRACT

Studies on the effect of wood ash, Tagetes minuta extract and hot water treatment on Enset root
mealy bug, Cataenococcus enset, incidence was carried out at three hot spot locations in southern
Ethiopia. Study was conducted in 2004 and 2006 cropping seasons. The result indicated that hot
water treatment killed 100% of mealybugs on the infested suckers as good as chemical insecticide
before planting where as the subsequence drench application of hot water didn’t kill 100 % mealy
bugs. Application of wood ash and T. minuta delayed the development of the mealybugs for the first
three months and then increase in population was observed. The highest pseudo stem circumferences
and height of plants were recorded from chemical treated plot followed by hot water treatment,
while the lowest was recorded from the untreated plot. The results of this study indicated that hot
water treatment reduced the initial population of the mealybugs and to further manage the pest
integration with other. To minimize the root shocking effect of wood ash it needs re-testing at
different rates and T. minuta would be included in the integrated pest management program to
manage the pest.
