A lawn mower having an internal combustion engine has a container of liquid insectide or other chemical that can be spread on vegetation during a mowing process hung on a crossbar of the mower. The container is fluidically connected to a muffler associated with the mower and chemical from the container is fed into the muffler to be mixed with hot exhaust gases flowing through the muffler from the engine. The chemical is vaporized, mixed with the hot exhaust gases and then dispersed as the gases are exhausted from the muffler.
