Heat and Oxygen Stresses and Rotations as Alternatives to Methyl Bromide in Crop ProductionEntry ID: USDA0527
Abstract: The objective of "Heat and Oxygen Stresses and Rotations as
Alternatives to Methyl Bromide in Crop Production" is to
characterize temperatures, redox potentials, and rotations that
will control undesireable organisms; to determine the role of
organic matter in modifying these stresses and providing
hospitable conditions for crop growth; and to develop cost
effective management systems that will ... provide pest control.
The purpose of this research is to develop methods to control
vegetable crop pests in soils using heat and oxygen stresses,
organic matter additions, and crop rotations.
Collection Organization: USDA Agricultural Research Service
Collection Methodology: Heat stress experiments to determine the
effectiveness of enhanced soil solarization for
plastic-covered-bed culture of vegetables. Capture of solar
radiation maximized by use of infrared-absorbing clear plastic,
"bubble-wrap" material and enhancement of penetration of heat
with hot water injection. Soil temperatures achieved with
enhanced solarization compared with standard practices. Oxygen
stress experiments conducted by flooding of soil during the
summertime off-season. Flooding effects on redox potential and
pest control conducted in conjunction with additions of organic
matter, enhanced-film solarization, production of an off-season
crop such as rice, and crop rotations.
Collection Frequency: Ongoing.
