SPRAYING CALENDAR 
This calendar, based upon the recommendations of the Agricultural Colleges and Experiment Stations of 
the country, is a brief guide for the general treatment of insect pests and plant diseases. 
Timeliness is one of the greatest factors in the control of diseases and pests; in order to spray intelligently, 
that is, to strike at the proper time, one should know at least the main facts in the life-history of the insect or 
disease sprayed against. Moreover, it will pay to remember that, for nearly all fungous diseases and some in¬ 
sects, spraying is a preventive, and to be most effective must be done at the time when attacks may be expected, 
without waiting for the enemy to become apparent. 
s pray only on clear, sunny days and finish the work early in the afternoon, so that the application will 
dry rapidly and before dew falls. Spray evenly and thoroughly, using ample pressure and a nozzle that throws 
a fine mist, but do not continue until the foliage drips. Never spray when the trees are in blossom. 
In general terms: 
POISONS, such as Arsenate of Lead, are used to control leaf-eating insects. Examples—Canker 
Worm, Potato Beetle. * 
CONTACT INSECTICIDES, such as Tobacco Extracts, Soap Sprays, Kerosene Emulsion, etc., are 
used in fighting sucking insects. Examples — Plant Lice, Squash Stink-bug. Sucking insects 
will not be killed unless they are hit by the spray. 
Bordeaux Mixture and Lime-Sulfur are for use against plant DISEASES.
