Granular insecticide Temik 10g (Aldicarb) was used in five doses of 0.0 (control), 0.4, 0.8, 1.6 and 3.2 g/plot (1.33 sq. ft) to evaluate any phytotoxic or phytotonic impact on Paulownia tomentosa PFI No. 19, at nursery stage. Measurements of parameters recorded one month and twenty days after treatment were plant height, number of leaves per plant, fresh weight of leaves, fresh weight of stem, dry weight of leaves, dry weight of stem and percent dry matter. Five plants per treatment were selected at random, then data were converted on per plant basis. Plant height was the only parameter which significantly increased in response to Temik, while others were non-significant. Temik 10g at the dose of 3.2 g/plot increased 32.13 percent plant height over control.
