A Brief Outline of the Best IVletliods for the Protection of Crops 



From Insects and Fungi. 



The utility of some condensed outline showing how and when to 

 ppray or otherwise treat fruit trees, shade trees, garden and lield 

 crops, and flowers, to prevent or check injuries by insects and 

 plant diseases, is demonstrated by the number of such publications 

 iri other [States. It is practically impossible, however, to include 

 in such a i)aper, all of the foes of the agriculturist, and accordingly, 

 only such are considered as have been found to be most likely to be 

 present in Pennsyhania. At the same time, treatment for the in- 

 juries touched on here, will, in nearly every case, also control those 

 not treated of, and, accordingly, in this way the ground will be 

 nearly as well covered as though all such foes were considered in 

 detail. .; .^ 



In all cases, treatment according to the directions here given 

 must be applied with judgment, as no tixed rules can be given which 

 v ill hold for every case, and an ignorant adherence to the direc- 

 tions without a knowledge of the particular conditions of the case, 

 Uiay fail to give the desired results. To obtain success in the con- 

 trol of insect and fungous foes, a knowledge of what the foe is, the 

 best way to attack it, and when this attack is most effective, are 

 necessary. 



Any information desired on these subjects may be obtained by 

 writing to the Division of Zoology, Department of Agriculture, 

 liarrisburg, Pa., and the sending of samples of injury done, or of 

 the insects or other foes causing the trouble will greatly aid in 

 giving satisfactory answers.
