given to fall treatment. At this time many of the mites have not yel 
gQne to the bud scales, hut occur in the pubescence of the young 
wood and are hence more easily killed. 
Lime-sulphur washes arc excellent treatment- for these mites and 
their employment is perhaps preferable as avoiding danger of injury 
to fruit buds by the oil sprays. If a lime-sulphur wash is employed, 
it should be applied with great thoroughness, completely coating the 
tree so thai when spraying is finished the tree will appear as if 
whitewashed. The homemade wash, according to the old formula, 
lime 20 pounds, sulphur 15 pounds, and water to make 50 galL 
will be quite effective; or the homemade or commercial concentrate 
may he used. The former may be made according to the formula. 
lime 50 pounds, sulphur LOO pounds, and water to make 50 gallon-. 
When thus prepared the concentrate should be used at the rate of one 
part to 9 or 10 parts of water. Applications of these washes may 
also be made in the fall as described for kerosene emulsion and in 
the spring, and if only one treatment is to he given the spring appli- 
cation is preferable, as it takes the place of the first application of 
a fungicide for apple scab. When the mite is quite troublesome both 
fall and spring treatments would insure its control more quickly and 
completely. 
On the pear the mites may be kept reduced to an important extent 
simply by searching out in the spring branches bearing worst infested 
leaves, pruning these oil' and burning them, or sprays may be em- 
ployed exactly as indicated for the apple, if this is considered 
necessary. 
Except in cases of serious infestation special spraying for the 
Mister mite will not be necessary. As to whether or not it i- advisa- 
ble to spray, the orchardists will have to decide after determining as 
exactly as is possible the amount of injury being done by the mites, 
and care should be taken not to confound with it- injury that which 
has resulted from fungicidal or Paris-green sprays, and from leaf- 
spot (li-ease-.
