Two supervised field experiments were conducted inthe bhendi hybrid MH 10 during kharif, 2012 and rabi, 2012-13 tostudy the impact of agrochemicals on spider population in Karaikal district, U.T.of Puducherry, India. The agrochemicals used were fertilizer, insecticide andherbicide individually as well as in combinations. It was found that the populationof spiders was higher in the untreated check (0.30 to 1.03/plant) while a lowpopulation was recorded in the treatment with herbicide + insecticide which rangedfrom 0.10 to 0.36/plant during kharif, 2012. In rabi, 2012-13, ahigher population was recorded in the untreated check (0.36 to 1.00/plant)while a low population was observed in the treatment with herbicide +insecticide (0.16 to 0.40/plant). It was also found that, the population washigher in the treatment with fertilizer alone (0.50 and 0.56/plant in kharifand rabi respectively) compared to the other treatments. From the twoexperiments, it was concluded that, an impact of agrochemicals namely herbicideand insecticide was observed on the spider population while a lesser impact wasnoticed in the treatment with fertilizer alone compared to the untreated check.
