GET RID OF THS CHOKSCHERRIES 



For those v/ho have peaches or are thinking of planting peaches 

 the time of year has arrived to get rid of the chokecherries around the 

 orchard site. The chokecherry is the alternate host for the X-disease, 

 or yellovz-red virosis, a very serious virus disease of peaches. This 

 disease travels very s lovely from peach to peach but very rapidly from 

 chokecherry to peach. The only knc/m control is to get rid of the 

 chokecherries in the vicinity of the orchard. These should bo eliminated 

 for a distance of 400 or 500 feet from the orchard, 



Chokecherries can be eliminated most effectively by a weed killing 

 spray. Cutting them off results in a forest of suckers and s]^ routs. 

 Digging then out is not effective because any pieces of root left will 

 send up sprouts. The most effective weed spray for this purpose is 

 ammonium sulfamate, or Animate, used at the I'ate of one pound per gallon 

 of water. It is most effective if applied when plants are growing 

 rapidly. It is less effective when applied after late August, 



Since ainmonium sulfair.ate is not a selective spray and is corrosive 

 on certain metals, it must be used around desirable plants with care, and 

 spraying equipment should be cleaned out very thoroughly after its use. 

 It is known to be quite toxic to peach troos, Therf^foro, it may be used 

 around the orchard but should not be used in thy orchard,

SEEN DT TliE FIELD 



H umming Bi r d at "vTor k, This spring for the first time v/e saw a 

 humming bird visiTing blueberry blossoms. The speed with vrhich it flew 

 from one tiny blossom to another v/as nothing short of tu-iiazins, and in 

 doing so it probably supplemented the v;ork of the bumblebee as a 

 pollenizer. 



An Ov ersized Crovm Gall , In digging some old raspberry plants, one 

 root, less than 1/4 inch in diaraeter carried a gall which Vv'as 1^ inches 

 in diametor and 4 inches long. Other galls the size of a pea or larger 

 were common, 



F lower ing Cr ab Blossoms on Late Grov.'th , A y>ung flov^-ering crab 

 tree in Amherst with a snowball bloom has one sprout which grev/ 7g- feet 

 in 1945, It evidently continued to grow until late fall evidenced by 

 the killing back of 6 inches of th^j immature tip. And yet there were 

 blossoms on the sprout v;ithin 10 inches of the tip, v/hich vrare probably 

 initiated in late September or October because that particular wood 

 didn't exist before the first of September,
