GLYODIN NOT AVAILABLE TO FRUIT GROWERS FOR 1971 



AND 

 PHENYL MERCURY ACETATE IS A BIT SHAKY

Glyodin is a good scab-control fungicide and it controls other 

 apple diseases too. The manufacturer has stopped making it because 

 there is not enough sold to make it pay. Our understanding is that 

 arrangements have been made with another manufacturer to produce 

 enough glyodin to make Glyodex - a combination of glyodin and do- 

 dine - for 1971 



Although phenyl mercury acetate is still registered by the 

 USDA and the State Pesticide Board and is allowed for use on apples, 

 as this is being written, the situation may change because mercury 

 has had some bad publicity in the press during the past year or so. 

 For this reason, and because it is considered prudent not to pro- 

 vide instant ecologists and antipesticide crusaders ammunition with 

 which to continue attacks on pesticides, phenyl mercury acetate 

 for apple scab control will not be included in apple pest control 

 programs in Extension program in Massachusetts in 1971.

 which Dr. Savage's talk was based. This research is quite intrigu-
