The injector method was ineffective, for in this experiment the disease appeared to be spreading almost as rapidly in the treated area as in the untreated area. The results of the residue analysis indicate that, despite the massive dosage of chemical appUed to a very small area, berries picked the yeai following treatment contained fer bam residues well below the toler-j ance limits established for thi: chemical (Table 1), 1.
