Abstract
The empirical study revealed that among the various types of constraints (as perceived by the respondents) regarding the adoption of IPM technologies in the Pointed Gourd (Trichosan thes dioica Roxb.) production, the lack of knowledge of the respondents about the Economic Threshold Limit (ETL) concept ranked first closely followed by the lack of knowledge of the respondents regarding the bio-pesticides (under the category of knowledge and information constraints) in second position, the lack of knowledge of the respondents about the Integrated Pest Management (IPM) techniques ranked third position, closely followed by lack of training of the respondents on the proper use of pesticides in the fourth position. The result also showed that among six numbers of different categories of perceived constraints, knowledge and information constraints with a rank score of 2769 enjoyed first rank position, distantly followed by administrative and managerial constraints (with a rank score of 1586) in the second position, technological and communication constraints with a rank score of 1249 in the third position, socio-economic constraint (rank score of 828) in the fourth position.

Highlights
Integrated Pest Management (IPM) is a scientific paradigm (Perkins, 1982) which is of global significance
Lack of preservation and cold-storage facilities enjoyed the first position might be because of the fact without proper preservation facilities, the Pointed Gourd growers were under pressure to sell the harvested Pointed Gourd crops immediately which in turn encouraged the Pointed Gourd growers to apply the pesticides more for increased level protection from the pests and vis-à-vis increased yield of the Pointed Gourd crops and the farmers tended to dissociate themselves from the adoption of IPM technologies in the Pointed Gourd cultivation
The fact that the knowledge and information constraints held the highest position among different categories of constraints might because of the reason that the respondents had very poor level of knowledge regarding the adoption of IPM technologies in Pointed Gourd cultivation as well as they had very poor access to the sources of the information regarding the adoption of IPM technologies which was already indicated in the different results obtained in the earlier sections of this paper
Summary
Integrated Pest Management (IPM) is a scientific paradigm (Perkins, 1982) which is of global significance. While the philosophy and ideas of IPM are widely accepted in the political and scientific arena, the practical implementation of IPM has proved far more difficult to achieve. A number of reasons for this limited success were identified by the different researchers viz.:. Commercial pressures on farmers to use pesticides, and the idea that pesticides companies disrupt IPM research and implementation activities could be important in specific cases. We believe that a more important reason for a lack of IPM adoption is that the IPM ‘product’ is often not appropriate to farmers’ need (Norton - 1976, Goodell - 1984). Farmers may perceive IPM as too complex, too expensive, too risky, and just not appropriate to their farming system
