Herbicides Corn Gluten Herbicides   Flamers are portable gas
torches that produce heat intense enough to boil the water in
plant cells. Killing a weed requires heat for only 1/10 of a
second. Flamers are usually used to kill young weeds in prepared
rows, just before seeds or seedlings are planted, as an
alternative to pre-emergent herbicides. Flamers become trickier
to use later, when the plants are actively growing, and they
cannot be used where mulches are present. Flamers also are quite
costly compared to a hoe, but may be a worthwhile investment if
you have a number of straight rows to weed. They also are useful
for killing weeds in between walkway pavers. The smallest models
consist of a backpack that holds propane fuel, a hose, and a
hooded nozzle at the end of a handle that resembles a carpet
sweeper.  GardeningwithKids.org Catalog  Help us put A Garden in
