A üeld experiment was conducted to study the spatial and temporal distributions of (EZ)-1,3-dichloropropene (1,3-D) in the soil and eþ ects on pest control efficacy. An emulsiüable concentrate formulation of 1,3-D (Telone EC) was applied with drip irrigation at 47 kg AI ha-1 to two diþ erent depths
