for temporary control of grasses . 



Grapes can be weeded with a directed spray jf DN+oil provided it does not hit 

 tender new shoots, T\to quarts of Doit General or Sinox ?/ vfith 15 gallons of fuel 

 oil and 85 gallons of vrater can be used as needed in established vineyards* 



The list of herbicides for cultivated blueberries is still short. DN at 3-U 

 pounds per acre will give terupoi-ary conti'ol of weeds during sujtnmer and fal] but 

 must be kept off tender new shoots. In clean cultivated fields a pre-eraergence 

 application of SES at 3 pounds per acre may be helpfulo 



Because of the provision of the Miller Bill and the lack of clearance on 

 several materials, the list of herbicides that can be reconunended in fruit plant- 

 ings at present is rather limited. As the 1956 season progresses and more inform- 

 ation required under the Miller Bill becomes available, more herbicides will be 

 [;ivcn clearance for use. Even when all those knoxvn to be useful have been cleared, 

 not all weed problems in fruit plantings will be solved. There is need for a 

 better material for control of summer weeds in strawberries. Grasses, especially 

 \Titch grass, can be a very trying problem where cultivation is undesirable or 

 impossible. Under these conditions no fully satisfactory control is available,

A^ im _B_ LUEB^RR Y DISEASE 



':irhat appears to be a new disease of the cTiltivated blueberry was found in a 

 field in Freetown, Massachusetts, in the spring of 1955 » Affected bushe9 may 

 have galls on all woody portions, both tops and roots. The galls on the top 

 portion of infected bushes closely resemble the galls of the cravm gall disease. 

 The striking difference is the appearance of gall on the root of the plants in- 

 fected with this new disease. Root s^Hs have never been observed on crown gall 

 infected cultivated blueberries. 



This root gall disease appears to be infectious but the causal organism is 

 not knoim. Work is under way to determine the cause and methods of control. 



Root gall disease has been found in only the one field. If anyone finds 

 blueberry plants vjlth galls on the roots, the authors vrould like to know about it,
