FUNG: AND FUKGICIDES. 



It will be readily seen that quick action, perseverance, and 

 good judgment on the part of the grower are necessary to 

 obtain satisfactory results. Especially is this true of the 

 internal fungi, which must be attacked before the germ-tube 

 enters the tissue. 



PEACH-LEAF CURL. 



In some seasons this fungus is very severe, and on some 

 varieties of peach more than on others. It can be easily 

 recognized by the abnormal growth of the leaf, which becomes 

 leathery, highly colored, and sometimes resembles a seed-pod 

 more than a leaf. 



In winter use the lime-sulphur-salt wash or the Bordeaux 

 mixture (formula A). 



Just as the buds are swelling use the Bordeaux mixture 

 (formula B). 



APPLE OR PEAR SCAB. 



This is one of the most common diseases of pomaceous fruits 

 the world over. It does not reduce the crop, nor does it seem to 



affect the vitality of the 

 tree, but it injures the 

 quality of the fruit, mak- 

 ing it unsalable. The 

 grower knows too well 

 that a scabby or a de- 

 formed pear has no sale 

 in the market or at the 

 cannery, in fact is only fit 

 for hog feed; therefore, 

 the utmost vigilance and 

 greatest care should be 

 exercised in the applica- 

 tion of remedies to check 

 this disease. The first 

 appearance of the scab is 

 seen upon the new growth 

 and small fruit as a velvety spot. The disease is easily recog- 

 nized, and' if not soon checked the velvety spots on the fruit 

 continue to spread until they have the appearance of black, 

 scabby, c.orky blotches. As the pears grow, the development 

 of the affected side is arrested, but the healthy side continues
