ANALYSIS OF TECHNOLOGY GAPS AND RELATIVE IMPORTANCE OF JASMINE BUDWORM, HENDECASIS DUPLIFASCIALIS HAMPSON IN TAMIL NADU
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
Surveys were conducted during 2015-2016, in major jasmine growing districts of Tamil Nadu, for assessing the distribution, infestation level and the relative importance of jasmine budworm, Hendecasis duplifasialis Hampson. The budworm incidence was more in Madurai (45.18 %) followed by Tiruneveli (41.35%), Dindugal (33.54 %) and Coimbatore districts (29.78 %). Fifty three per cent respondents ranked budworm as the most important pest. The technological gap indices (TGI) were high in adopting right frequency in spraying of chemicals (91 %), usage of biological control agents (87 %) and effective cultural practices viz., regular raking of soil to destroy pupa (85 %) and collection and destruction of fallen and discolored buds and flowers (82 %). A majority of respondents (52.94 %) had high level of technological gap, whereas, only 11.76 % were in low level of technology gap. Thus, efforts should be taken to create awareness among jasmine growers for the use of eco-friendly bio-control methods against jasmine budworm as well as other pests of jasmine.
