Abstract and summary

Herbicidal rates (5 to 9 lb/A) of 2-chloroallyl diethyldithiocarbamate (CDEC) retarded emergence of head lettuce (Lactuca sativa L.) reduced both pre- and postthinning plant populations, caused injury symptoms in young plants, affected the subsequent rate of growth, date of maturity, weight of marketable heads, and yield. Decreased yields were attributed to a reduction in plant population, poor head solidity, and small head development. Reductions in yield were in proportion to dosage and of economic importance.
