Response of Texas Root Rot to a Soil Sterilant the Second Year After Application in Marana, 1988
MetadataShow full item record
AbstractMethyl bromid/chloropicrin, a soil sterilant, was deep injected into cotton beds 10 days before planting in 1987. The 1987 cotton lint yields were significantly increased by injecting the sterilant into the Texas root rot kill areas. Cotton yield and mortality data were taken in the same plots in 1988 to measure the carry-over of the treatments. Lint yields trended higher and plant mortality trended lower in the sterilant- treated plots, but no significant differences were detected.
