Soil fumigation remains an essential practice for managing soilborne pathogens, nematodes, and weeds in high-value vegetable production systems. Traditional shank injection provides effective fumigant placement but is associated with high equipment costs, increased soil disturbance, and operational constraints. Drip-applied fumigation has emerged as a potential alternative in plasticulture systems where drip irrigation infrastructure is already in place. This publication examines the principles, advantages, and limitations of drip-applied fumigation compared with shank fumigation, with emphasis on fumigant distribution and pest control efficacy.
