A total of 60 farmers (30 open field and 30 greenhouse) interviewed were randomly selected from the two sub county. The selection of farmer was done in conjunction with the Ministry of Agriculture staff in the respective sub county. Both primary and secondary data were collected in this study. Primary data was obtained from direct interview of the farmers whereas secondary data was obtained from the various Ward Agricultural Extension offices. A structured questionnaire was administered to each respondent through one farm visit using the most appropriate language or interpreter where necessary. In addition field observations were carried out to verify information provided where the tomato crop was available.

The farmers indicated that they experience a crop loss of more than 50% in both short rain and dry seasons if proper control measures were not applied
