APPENDIX B 



young growing buds and any that begin to turn 

 brown or black and die must be removed and 

 destroyed. As the buds grow older and approach 

 the blooming time, the infection will usually be 

 first evident at the base of the bud on one side as 

 a brown lesion, which will gradually spread up, 

 involving the entire bud, turning it brown. 

 Spreading downward it gradually involves the 

 entire circumference of the stem. It will be very 

 important to detect these lesions in the early 

 stages and remove the diseased buds, for spores 

 are produced most abundantly on rotted buds and 

 are also in the most favorable position for distri- 

 bution by wind and insects to healthy buds. 

 Spotted leaves should also be promptly picked 

 oif . However, if the early spring inspection and 

 eradication operations have been thorough and 

 there are no diseased peonies near by, the foliage 

 will probably suffer but little. In wet seasons 

 these inspections should be made daily. In dry 

 weather less often will suffice. For the nursery- 

 men or the grower of large numbers of peonies, 

 this method of control may not be profitable, but 

 for the small grower or in the private garden 

 where a relatively small number of clusters are
