Spraying is usually done in the summer months 

 in between the growths, that is, when one growth 

 has finished and before the next starts. For spray- 

 ing at such times each gallon of the emulsion is 

 diluted with not less than ten gallons of water ; but 

 for trees that are in active growth fifteen gallons of 

 water to one of the emulsion will be strong enough 

 for the young foliage to withstand. For badly 

 affected trees two sprayings about a fortnight apart 

 may be necessary to eradicate the scale. 



Resin Wash. Owing to the scalding effect upon 

 the leaves and fruit that sometimes follow the use 

 of the various oil sprays, some growers prefer spray- 

 ing their citrus trees with a resin wash made up in 

 the proportion of 1 Ib. resin, 1 Ib. washing soda, 

 J Ib. soap, to 5 gallons of water. This is applied in 

 a similar manner as the oil sprays, and usually but 

 little damage to the foliage of the trees is done. 



NoU. -No spraying of citrus trees should be 

 attempted if the trees are in want of moisture, as 

 when in this condition the leaves of the trees have 

 often not sufficient vitality to withstand the suf- 

 focating effects of the spray, and so fall off ; whereas 

 it the spraying takes place when the leaves are full 

 of moisture, such as after an irrigation, and other 

 conditions are favorable, ill-effects seldom follow.
