SOME IMPORTANT LITERATURE ON PLANT 



DISEASES THE GARDENER 



SHOULD HAVE. 



By J. J. Taubexhaus, M. S., Assistant Plant Pathologist, 

 Del. Exp. Stations, Newark. Del. 

 "Knowledge is power." There are very few of us 

 who beheve that we know it all. The successful gar- 

 dener is always on the alert to gather new ideas, to learn 

 new facts, and to constantly equip himself with a vast 

 amount of knowledge in order to help him solve his daily 

 problems. Gardeners are often met with failures in 

 their attempt to grow crops successfully. These failures 

 are often directly attributed to diseases induced by 

 parasitic insect fungi or bacteria. There are plenty of 

 horticultural books on the market in which one can find 

 useful information on plant cultivation. There are, 

 however, very few accessible sources where the gardener 

 can go for information on plant diseases and their con- 

 trol. Experiment Stations all over the country are bus- 

 ily engaged in solving the problems which daily beset the 

 agriculturists. The information which these Stations 

 furnish is all printed in bulletin form. These are sent 

 free to all who ask for them. Our most useful and 

 up-to-date information on plant diseases and their con- 

 trol can be found in these bulletins, although there is a 

 lot of scattered literature in periodicals w'hich is easily 

 accessible. It is true that most of these bulletins are 

 more or less of a technical nature, nevertheless, most 

 bulletins do not lose sight of the practical and economical 

 point of view. For the benefit of those who are inter- 

 ested, the following is a brief list of bulletins on plant 

 diseases and their control. Each of these bulletins 

 (unless the edition is exhausted) can be obtained free of 

 charge, by merely addressing a postal card to the Direc- 

 tor of the Experiment Station whence the bulletin is 

 desired. The post office address of each Experiment 

 Station will be given in parenthesis with each reference. 

 It is also urged that every gardener should write to each 

 Experiment Station to have his name placed on their 

 mailing list and specify the subject in which one is most 

 interested.
