Sorption of Fumigants to Agricultural Films
Plastic tarps are often used in soil fumigation to contain chemicals in the soil to increase efficacy and decrease emissions of fumigant vapors. This research has shown that plastic films have a significant capacity to sorb fumigant vapors and that the sorption is largely reversible. We tested three agricultural films (polyethylene and two highbarrier films) with four soil fumigants (methyl bro...
متن کاملInhalation Risks from Phosphide Fumigants
A 48 year old male acutely develops symptoms of chest pain, shortness of breath, dizziness, and nausea with an episode of vomiting. The symptoms develop acutely at the workplace, where he is employed as a production worker at an aluminum phosphide manufacturing facility. He is brought to the company physician and is noted to be alert and responsive with a normal respiratory rate, but appearing ...
متن کاملImpact of fumigants on soil microbial communities.
Agricultural soils are typically fumigated to provide effective control of nematodes, soilborne pathogens, and weeds in preparation for planting of high-value cash crops. The ability of soil microbial communities to recover after treatment with fumigants was examined using culture-dependent (Biolog) and culture-independent (phospholipid fatty acid [PLFA] analysis and denaturing gradient gel ele...
متن کاملIncompatibility of metam sodium with halogenated fumigants.
Metam sodium (metam) is a widely used soil fumigant. Combined application of metam and other available fumigants is intended to produce synergic pesticidal effects for a broad spectrum of pest control in soil fumigation. This study aimed to test the compatibility of metam with the halogenated fumigants 1,3-dichloropropene (1,3-D), chloropicrin, methyl bromide, methyl iodide and propargyl bromid...
متن کاملHarmful effects of mustard bio-fumigants on entomopathogenic nematodes
Mustard (Brassica and Sinapis spp.) green manures tilled into the soil preceding potato crops act as biofumigants that are toxic to plant–parasitic nematodes, providing an alternative to synthetic soil fumigants. However, it is not known whether mustard green manures also kill beneficial entomopathogenic nematodes (EPNs) that contribute to the control of pest insects. We used sentinel insect pr...
