sulphur, to which a pound of at -senate powder has 

 been added, and again two weeks afterward. 



When a peach tree has brown rot all mummies left 

 on the ground should be carefully gathered and 

 burned to prevent the spread of the trouble. 



Commercial lime sulphur is likely to burn the 

 foliage if it is used on peach trees in summer and 

 should be diluted in the proportion of one part 

 water to one hundred and fifty parts of lime sul- 

 phur before using. 



Examine all trees carefully before planting and 

 if there are black, gall-like growths on twigs and 

 branches the trees have black knot. These knots 

 should be cut off and burned during the cold days, 

 using care to remove several inches below the 

 affected part. 



When large limbs of peach trees are affected with 

 black knot it may be well to try spraying with 

 lime sulphur before deciding to cut them off, and 

 then painting the surface with several coats of 

 good lead paint. If this fails, they should be 

 removed in order to save the rest of the tree. This 

 applies also to other fruit trees, such as plum and 

 cherry.
