USDA APPROVES THERMAL WEED CONTROL FOR ORGANIC PRODUCTION

COMMERCIAL growers have used propane flames to kill weeds for years, and now organic growers may do the same. The USDA recently approved thermal weed control as an authorized organic production practice. The USDA rules added heat and flame to the allowed weed-control methods.

Propane-generated heat or flames will eliminate weeds invading any crops. The benefits of heat are that it cannot be reversed by rain or other chemical treatments and weeds will not develop a resistance to extreme heat.
