Abstract
An experiment was conducted at Nagari union in Kaligonj Upazila of Gazipur district to determine the impact of Integrated Pest Management practices on tomato cultivation. Data were collected by using pre-designed interview schedule from 1st March to 5th August, 2014. The results of the study showed that in the study area farmers cultivated tomato in 14.6% of their land and there are eight IPM practices which are generally used by the farmers in their tomato fields. Regarding the overall adoption of IPM practices in tomato cultivation, 65.0% respondent farmers were in medium to high adoption category. The IPM Practice Use Index (IPUI) was found significantly higher in case of IPM adopters than in case of IPM non-adopters. But “use of pheromone trap”, “setting up the bamboo stick in the field” and “cultivation and use of green manure” were ranked as 1st, 2nd and 3rd, respectively in case of IPM adopters whereas “setting up bamboo stick in field”, “cultivation and using green manure” and “use quality and resistant seeds” obtained 1st, 2nd and 3rd rank, respectively in case of IPM non-adopters. The average infestation of insect and disease was found significantly lower in the fields of IPM adopter (9.7%) than IPM non-adopter (11.8%). The average frequency of chemical use in the season was also significantly lower in the fields of IPM adopter (2.14 times) than IPM non-adopter (3.44 times). The marketable yield was found significantly higher in the fields of IPM adopter (51.34 t/ha) than in the fields of IPM non-adopter (42.24 t/ha). The average gross return was also significantly higher in case of IPM adopter (526,143 taka/ha) than IPM non-adopter (472,647 taka/ha). The Benefit-Cost Ratio (BCR) of IPM adopter (2.41) was also found significantly higher than the BCR of IPM non-adopter (1.44).

There are few studies examining the effectiveness of an IPM program on tomato cultivation. [12] found that IPM farmers reduced the number of pesticide use application up to 89 percent and at the same yield increased to 10 percent. [13] reported that IPM trained farmers reduced the num
Summary
Tomato is the most consumable vegetable crop after potato and sweet potato occupying the top of the list of canned vegetables and plays an important role in providing balanced nutrition. The few IPM (Integrated Pest Management) studies [4] [6]-[11] conducted in tomato cultivation were focused on cost and return only. It needs to consider food safety issues so that it will be safer and healthier. To minimize the chemical inputs and save environmental damage, IPM approach has been globally accepted for achieving sustainability
