The awareness, knowledge, attitude and adoption of the root (wilt) management practices were found to be very low among the farmers of root (wilt) affected area. This disease affects the socio economic conditions due to the reduction in coconut yield. Central Plantation Crops Research Institute, Kerala (India) has developed effective integrated management technology for improving the health and yield of disease affected palms. Due to the perennial nature, prevalence of the disease in the State for more than ten decades, attitude of the farming community and other social/economic constraints, the linear model of Transfer of Technology (TOT) could not create the desirable effect. Hence an innovative Participatory Technology Transfer (PTT) approach was implemented in severely root (wilt) affected district-Alappuzha during 1999-2003. The impact analysis indicated significant improvement in awareness (14 to 32.5), knowledge (19 to 59.5), attitude (22.5 to 36.5) and adoption (16 to 45.5) of practices as well as the scope for scaling up the TOT model in root (wilt) affected areas. The PTT enabled participation of major stakeholders in the TOT process. The categorization of the farmers indicated significant shift to the higher level of awareness from 63.00 to 92.00 %, higher level of knowledge from 14.00 to 74.50 % and higher adoption level from 27.50 to 57.00% after three years of PTT approach implementation.
