The study entitled “Technology assessment of plant protection practices of economically dominant crops in homegardens’' conducted in the Thiruvanathapuram district of Kerala state covering 100 homegardens having an area more than 25 cents were selected from five Agroecological units (AEU) viz.. Southern coastal plains, Southern central laterites, Southern high hills, Southern central foothills and Southern laterites. Twenty operational homegardens from each of the five panchayats belonging to the selected AEUs were chosen making the total sample size to 100 respondents. Delineation of economically dominant crops in homegardens, levels of adoption of selected KALJ plant protection practices, technology need assessment, constraints in adoption of plant protection practices and suggestions as perceived by the farmers were the major objectives of the study.
The independent variables selected through judges rating were age, education, occupation, effective homegarden area, family size, farming experience, information source utilization, rational orientation, extension participation, knowledge, evaluative perception on sustainability of plant protection practices and economic motivation. The independent variable selected was adoption of selected KAU plant protection practices.
The economically dominant crops identified were coconut, banana, tapioca, pepper, vegetables, yams and colacasia and arecanut respectively in the homegardens.
The overall level of adoption of selected plant protection practices showed that majority (70%) of the respondents had medium level of adoption followed by 16% having high level and 14% low level of adoption. The adopter category curve delineated for the overall adoption showed that 45% of the respondents fell under early majority followed late majority (21%), laggards (16%), early adopters (14%), with no innovators. Differences in adopter categories were observed for different crops.

Age, information source utilization and extension participation were found to have significant positive relationship with the dependent variable adoption of selected plant protection practices of KAU.
In coconut, banana, tapioca and arecanut ease in operation was perceived as the most preferred plant protection criteria in homegardens.
The result showed that 45% of the farmers found the preferred KAU plant protection practices to be useful however only 40% of the respondents felt it effective.
Of the 17 ITK plant protection practices, four were specific to vegetables and banana each. Two were specific to plant protection of coconut and six of general practices.
Major constraints identified were, plant protection chemicals not effective in their recommended dosage, followed by climatic influence on pest and incidence and non availability of plant protection chemicals. Suggested refinement in plant protection technology as perceived by the homegarden farmers were in generating of ecofriendly and organic plant protection measures that are suitable for homegardens followed by timely availability of plant protection inputs and generation of more pest and disease resistant varieties.
