Study of Methyl-Bromide as Weed Control in Parsons Nursery

The study of methyl-bromide as a weed control in the Parsons Nursery was started in 1949. On June 1, one of the standard seedbeds, prepared for spring-sowing, was treated with Dowfume MC-2 under a gas-tight cover. The bed had been prepared in the usual manner by tilling to a depth of 6 to 8 inches with a Seamantiller. After tilling the bed was covered with a sheet of Sisalkraft paper supported above the soil on small wooden horses and covered around the edges with soil shoveled from the paths. The methyl-bromide was applied with the "Jiffy applicator" at rates of one-half and one pound per one hundred square feet. The air temperature was 80°F at the time of treatment and minimum temperatures were 44°F while maxima remained at 80°F for the period of treatment. The gas-tight cover was removed on June 3 after being in place 44 hours.
