utility of the newer and more efficient spraying mixtures for dip- 
ping purposes. Prof. C. P. Close’ of the Delaware Experiment 
Station, has made some extensive tests to ascertain the effects of 
immersing fruit trees in oils, oil emulsions and the lime-sulphur 
wash. The results of these tests indicated the danger of wetting 
roots with contact sprays. The tops of the trees, especially of 
apples, proved much less sensitive to injury. In 1904, Mr. F. W. 
Faurot? dipped a number of trees in the lime-sulphur wash with 
slight losses. A test was again made in the following year with 
twenty-five apples and twenty-five peaches. None of the apples 
sustained injuries while four of the peaches were killed. A portion 
of this loss was attributed to adverse conditions in planting. 
Dipping of nursery trees in the lime-sulphur wash has been 
practiced quite extensively in Georgia, and the results have ap- 
parently been satisfactory. An experiment conducted by Prof. 
Wilmon Newell’ indicated, however, that injuries might follow this 
treatment; and on the basis of his results, warning was given to 
fruit-growers of the possible damages to young trees by this prac- 
tice. Dr. G. F. Warren* made a test with 100 Mountain Rose 
peaches, to determine the effects of dipping in the lime-sulphur 
wash on the health of the trees. One lot of trees was immersed in 
the lime-sulphur wash of double strength. No apparent injuries 
attended the treatment, even when the roots were immersed. In an 
experiment conducted by Prof. J. L. Phillips,’ of Virginia, apple 
trees allowed to remain in the standard lime-sulphur wash at tem- 
peratures of 60° to 120° F. for five minutes, sustained only slight 
injuries. The effects of the dipping on peaches were much less 
favorable, for many trees died as a result of the treatment. Im- 
mersion in this wash did not entirely rid the plants of the scales. 
Dipping of nursery trees in liquid sprays is not generally prac- 
ticed by nurserymen and fruit-growers, and its use seems to be 
largely experimental. There is very little definite knowledge of 
the real advantages to be derived from this practice and of the con- 
ditions under which immersion of plants can be safely employed.
