SPRAYING TO DESTROY INSECTS AND FUNGI. 



SUGGESTIONS FOR THE SEASON OF 1894. 



As the season of growth approaches the question comes to us, in 

 the form of frequent letters, " What shall I do to protect my fruit 

 and other crops from fungous and insect enemies?" This question 

 we shall attempt to answer in this bulletin. The past year has again 

 demonstrated the fact that we cannot expect perfect products nor 

 large yields from any crop without doing something to protect it from 

 these enemies. Seasons differ very much in the prevalence of insect 

 life or fungous growth, in some the crops being almost exempt from 

 injury from one or the other or both. During a cool, dry season the 

 fungi grow very slowly, if at all, while if hot, moist weather prevails 

 they develop with wonderful rapidity. The same may be said of 

 insect life, and could we predict with certainty what the season is 

 going to be, we could frequently dispense with the use of fungicides 

 and insecticides. But we cannot in auy way now known to science 

 foretell whether insects and fungous growths are to be abundant or 

 not, and are therefore compelled to prepare our engines of destruc- 

 tion and have our insecticides and fungicides ready upon the foliage 

 and fruit at the time when such enemies are likely to appear.
