OrvEr to Erapicatr Diskasez. 
a , being a duly authorised person, hereby give you 7 
of , notice that your orchard is diseased with , and I order 
you to take the following measure or measures within , for the eradication 
of such disease or diseases :— 
(a) All fallen fruit of whatever kind (and whether harbouring insects or not) 
shall be gathered before noon of each day and all pest-infested fruit shall 
be submitted to the process of boiling or be buried beneath not less than 
one foot six inches of solid earth: 
(6) The trees shall be sprayed with one of the following mixtures (the number 
of sprayings and intervals between sprayings to be stated) :— 
1.— Resin wash for scale insects. 
Take 20 Ib. of resin, 6 1b. of caustic soda (70 per cent.), 3 pints of fish oil, water 
to make 80 gallons. Place the resin, caustic soda, and fish oil in a large boiler 
with 20 gallons of water, and boil for three hours, then add hot water slowly and stir 
well till there are at least 40 gallons of hot solution; then add cold water to make up 
the total to 80 gallons. Never add cold water when cooking or the resin will be 
precipitated, and it will be difficult to get it in solution. ‘The above is the strength to 
use for citrus trees ; a winter wash for deciduous trees may be used one-half stronger, 
the total amount being made up to 54 gallons instead of 80 gallons.
