Judging from the results of 1 year''s orchard tests it appears that DDT may prove a good substitute for Pb arsenate under western New York conditions. Used at the rate of 0.8 lb. in 100 gal., control equal to that with 3 lb. of Pb arsenate could be expected. Larger amts. may prove more effective than the arsenical. There was no apparent injury either to the trees or fruit following applications of DDT, although a distinct bronzing was noticeable on the foliage late in the fall. There was little or no visible residue at harvest fol- lowing 5 cover sprays and the cost at present is little more than that of Pb arsenate. Undoubtedly DDT will not be used extensively on fruit until after a tolerance has been established. However, contrary to some of the early opinions, DDT residue appears to either weather off or possibly break down into a less toxic form following application.
