Abstract
Greenhouse-grown 5-month-old Kenland red clover from Brookston clay loam Crosby silt loam treated with 0.1, l.0, 10, and 100 p.p.m. BHC was analyzed for BHC content by the Schechter-Hornstein method. Averages of 0.08, 0.16, 0.91, 13.84 p.p.m. BHC and 0.10, 0.24, 2.07, 14.53 p.p.m. BHC for the respective soils and concentrations were found in the clover hay. BHC dosages of 200p.p.m. in Brookston soil and 100 p.p.m. in Crosby did not affect germination. Brookston soil required twice the BHC concentration present in Crosby to produce an identical effect on growth. Stunting, malformation, and mortality of young plants was proportionate to BHC dosage. Complete recovery from phytotoxic manifestations occurred in plants surviving beyond the ninth week.
