The pesticides evaluated comprised one synthetic insecticide (dimethoate) and four botanicals (A.indica oil, NSKE, V.negundo oil and Eucalyptus oil). The maximum reduction in the population of insect pollinators was due to dimethoate (0.3%); while, the population reduction of pollinators due to botanicals after the two sprays was significantly less with the least being in Eucalyptus oil (3%), followed by V. negundo oil (3%); however, treatment of coriander with V. negundo oil (3%) for aphid management gave maximum seed yield of 2.42 & 2.29 kg/12 sq. m. during 2015–16 & 2016–17, respectively; with a corresponding yield of 2012.50 & 1908.33 kg/ha.
