Abstract
Excised tubers of nutgrass, Cyperus rotundus L., placed in flasks containing either vermiculite or soil, were killed by fumigating with a commercial formulation containing 55 per cent of l-chloro-3, bromopropene (CBP), added at the rate of 0.04 ml per liter of confined space. Maximum kill was attained after 5 hours’ fumigation. The effectiveness of the fumigant was largely independent of temperature; but soil-moisture content three quarters or more of field capacity restricted movement of CBP vapor through the soil and imparted varying degrees of protection from the fumigant. Preliminary field trials indicate that 80 gallons of CBP formulation per acre, injected 8 inches deep with a weed gun, may be expected to give effective control of nutgrass infestations on well-tilled soils of moderately low moisture content. Soil compaction limited movement and reduced the effectiveness of the fumigant under field conditions.
