Dosage values obtained following pre-plant fumigation for perennials. 1.1,3-dichloropropene nematicides in eleven field situations

The movement of 1,3-dichloropropene nematicides in 11 different field situations was monitored. The eventual dosages of 1,2-dichloropropane and 1,3-dichloropropene achieved at various positions in the soil profile are reported. Soil moisture, temperature, texture and profile differences are indicated for each experiment. The influence of soil profile modification, surface sealing techniques and various methods and rates of application are reported.
