The risk of HL was elevated and showed evidence of a positive trend by number of pesticides used for the younger age group, but not in the older age group (ORs for five or more pesticides were 1.79 (95 % CI 0.93–3.43) for lesser 40 years and 0.84 (95 % CI 0.46–1.54) for[40 years) and for fungicides (ORs for two or more fungicides were 3.76 (95 % CI 0.96–14.75) for lesser 40 years and 0.19 (95 % CI 0.03–1.39) for Greater than or equal 40 years).
