INSECTICIDES AND 

 FUNGICIDES 



FOR FARM AND ORCHARD CROPS 

 IN MASSACHUSETTS 



By E. B. HOLLAND, A. I. BOURNE 

 and P. J. ANDERSON 



The successful production of farm and orchard crops de- 

 pends in large measure on the protection afforded against 

 injurious insects and diseases. For this purpose a large num- 

 ber of insecticides, fungicides and combinations of the two 

 have appeared on the market. It is to aid the purchaser in 

 interpreting the guaranties of these materials that this bulletin 

 is issued. Tables giving standard formulas for application, a 

 diagram showing safe and dangerous mixtures of materials, 

 and a table showing the guaranties of a number of proprietary- 

 articles are included. The more complete bulletin will be sent 

 on request. 



Requests for Bulletins should be addressed to the
