Principal Washes used as Sprays against Insects & Mites — contd. 
Uses. — This wash acts as a cleanser of the trees, removing moss, 
lichens, algse, &c. It also kills the delicate ova of the mussel scale. The 
caustic soda does just the same, but is not so rapid in action on the delicate 
ova of the mussel scale. 
Time of Application. — Any time between November and February. 
This may be advised as a wash in old orchards, or where mussel scale and 
oyster shell bark louse are troublesome. 
LIME AND SALT WASH. 
This wash has come into use mainly on account of its tending, more 
than anything else, to prevent the damage done by the Apple-sucker. 
Formula. — Lime i-ii cwt. 
Salt 30-40 lb. 
Water 100 gallons. 
Preparation. — Get fresh lime of the best possible quality (flare lime is 
found to be the best) and let it slake gradually, and then mix it with the 
water in which the salt has been dissolved, and strain through a fine sieve 
or sacking into another receptacle. 
Uses. — For the prevention of hatching of the eggs of Apple Sucker, 
I’lum Aphis, and mussel scale, and for cleansing the trees of moss, 
lichens, &c. 
Time of Application. — The end of February to the beginning of April. 
Spraying should cease as soon as the buds open.

Formula— Lime 3 lb. 
Sulphur 3 lb. 
Salt 3 lb. 
Caustic Soda 1 lb. 
Water 10 gallons. 
Preparation. — Mix the soda and lime together, and slake with hot 
water in which the sulphur has been incorporated ; then stir and add the 
salt, let this boil for some time and then add the full quantity of water.

must cease as soon as the bud scales are fully opened. A heavy spraying 
is best.
