La agricultura Canadá y otras entidades norteamericanas continúa vigilando la miel y el sulfa (usado para el control de loque americana) y los residuos fénicos del ácido o del fenol (usado para quitar abejas de la alzas) se ha encontrado. El uso del sulfa es especialmente difícil de entender como la terramicina es un alternativa legal que trabaja del mismo modo que. Con la consequencia de que se ha econtrado resistencia de la terramicina puede aparecer otra vez este fenómeno. Referente el fenol o ácido fénico, se han reevaluado y a se han mejorado los escapes de la abeja, y los sopladores están también disponibles.

NOTES: Conclusions. - '1. When Sulfathiazole At The Rate Of 3.5 Gm. Per Gallon Of Sugar And Water Mixture Is Fed To Colonies Of Bees Infected With American Foul Brood, The Disease May Be Eleminated For A Period Of At Least 2 Years Subsequent To The Treatment. '2. That When Sulfadiazine Or Sodium Sulfathiazole Are Fed In The Same Amounts, The Treated Colonies React To These Drugs In A Manner Practically Identical To That When Sulfathiazole Is Used. '3. That Sulfaguanidine, Although Promising As A Control Drug, Is Much Slower In Action Than The Preceeding Drugs. '4. That When Sulfathiazole, Sodium Sulfathiazole Or Sulfadiazine Is Fed To A Diseased Colony In A Multiple-Sectioned Hive, The Treatment Must Be Prolonged To Offset Any Lurking Spores Contained In Hidden Scales Or Old Honey Stores. '5. That The Population Of A Diseased Hive, The Number Of Diseased Frames And The Amount Of Old Stores Present Are Factors Influencing The Length Of Treatment. '6. That All Cells In All The Frames Must Be Cleaned And Used By The Bees During The Period Of Treatment. '7. That The Sulfa Drugs Will Be Deposited In The Surplus Honey If Treatments Are Made During The Period The Colony Is Gathering Such Stores. '8. That Is Colonies Respond Rapidly To The Treatment, There Is Little Or No Danger Of Robbing. '9. That A Diseased Colony May Be Stimulated In Brood Rearing By Feeding It A Sugar Water Solution To Aid In Maintaining The Hive Population But The Disease Will Persist. '10. That The Viability Of Spores Treated With Accoustical Power Of 100 To 150 Watts Delivered By An Ultra Sonic Machine Was Not Materially Affected.'
