Observations on the Application of Fungicides 
and Insecticides. 
The practice of spraying has passed beyond that period in its 
development when it was looked upon as an experiment. Numer- 
ous results, obtained by practical men, yearly demonstrate the 
fact that plant diseases and insect pests can be held in check by 
its means and that with a great profit to the grower. The 
unusual weather of the year 1894 brought about conditions that 
tended to make even the most skeptical look toward spraying for 
relief. The long continued wet weather of the spring was par; 
ticularly favorable to the growth of many kinds of fungi. — This 
was followed by the prolonged drouth of the summer which 
favored the development of countless hordes of insect pesis. 
Where the spraying was well done the results obtained during the 
past season have given the usual satisfaction. 
Since people are generally becoming convinced that it pays to 
spray, there is a growing demand from all parts of the State for 
information concerning spraying, and especially in regard to 
spraying apparatus. To meet this demand the following pages 
are devoted to a discussion of some of the machinery that is now 
being offered to the public for use in applying insecticides and 
fungicides. 3 
Paris green and kerosene emulsion still remain the leading 
insecticides, and since the introduction of Bordeaux mixture about 
ten years ago, no fungicide has been found that can be used with 
equal success in combating such a variety of plant diseases. When 
first brought into notice Bordeaux mixture was made in the form 
of a thick paste and applied with a brush; its strength and 
thickness has gradually been reduced till to-day we have the 
dilute mixture that is easily applied in the form of a spray. 
The use of Bordeaux mixture more than any one thing has 
caused rapid advancement to be made jin the methods of apply-
