ever bugs or flea beetles are plentiful add one to two pounds of 
paris green or two quarts of arsenite of soda stock solution to 
the quantity of bordeaux required to spray an acre.!? 
Thoroughness of ‘application is to be desired at all times, but 
is especially important when flea beetles are numerous or the 
weather favorable to blight. Using the same quantity of bor- 
deaux, frequent light applications are likely to be more effective 
than heavier applications made at long intervals; e. g., when a 
horse sprayer carrying but one nozzle per row is used, it is 
better to go over the plants once a week than to make a double 
spraying once in two weeks. A good plan is to use one nozzle 
per row in the early sprayings and two nozzles per row in the 
later ones. 
Those who wish to get along with three sprayings should post- 
pone the first one until there is danger of injury from bugs or 
flea beetles and then spray thoroughly with bordeaux and poison. 
The other two sprayings should likewise be thorough and ap- 
plied at such times as to keep the foliage protected as much as 
possible during the remainder of the season. Very satisfactory 
results may be obtained from three thorough sprayings. 
_ A single spraying is better than none and will usually be 
profitable, but more are better. Spraying may prove highly 
profitable even though the blight is only partially prevented. 
It is unsafe to postpone spraying until blight appears. Except, 
perhaps, on small areas, it does not pay to apply poison alone 
for bugs. When it is necessary to fight insects use bordeaux 
mixture and poison together.
