Abstract

Bacterial wilt (Ralstonia solanacearum) is among the major  diseases  affecting  tomato  production.  It causes the crop to wilt and completely die reducing the yield per  acreage.  The  objective  of  this  study  was  to  be determine  the  status  of  bacterial  wilt  in  Kajiado  and Kirinyaga County. Out of 60 farmers identified, a sample of 30 farmers were chosen using a multistage sampling technique.  Plant, water and soil samples were picked from their farms for isolation of Ralstonia solanacearum (Rs) bacteria in the plant pathology laboratory at Kenya Agricultural Livestock and Research Organization. Data was analyzed by finding frequencies using excel and SPSS software. Over 90% of the respondents from Kajiado and Kirinyaga counties reported to have experienced bacterial wilt of tomatoes in their fields. The disease was found to be important in Kirinyaga and moderately important in Kajiado counties. Crop rotation and fallowing were the main methods used to manage bacterial wilt. Many soil  samples  from  Kirinyaga  County  turned  positive for  bacterial  wilt,  unlike  those  from  Kajiado  County. Farmers from both Kirinyaga and Kajiado counties should therefore be taught the most appropriate, effective and environmentally friendly methods of controlling bacterial wilt of tomatoes in their fields.
