The Spraying of Orchards. 301 



20. Neither Paris green nor London purple should be used upon 

 peach trees unless the mixtures are very dilute, or lime is added to 

 neutralize the caustic action of the arsenites. ( Page 288.) 



21. Fostite gave only negative results when applied to peach foliage. 

 ( Page 288.) 



22. The Bordeaux mixture, when properly applied, practically protects 

 the foliage of a])ples, quinces, dewperries, raspberries, blackberries, and 

 gooseberries from fungous attack. ( Page 291.) 



23. Copper chloride can be used as a fungicide to advantage when 

 the solution is so strong that lime is required to neutralize its caustic 

 action. On the whole, it is a promising fungicide. (Page 292.) 



24. The experiences of the past season show no practical benefits 

 arising from applications of iron chloride. ( Page 292.) 



25. Zinc chloride, as used the past season, cannot be applied with 

 profit as a fungicide. ( Page 293.) 



26. Zinc sulphate has thus far proved of no practical value as a 

 fungicide. (Page 293.) 



27. Fostite contains about two per cent of copper. (Page 293.) 



28. Fostite possesses some fungicidal value, but its application to 

 trees is difficult and the beneficial action so moderate that it cannot be 

 generally recommended. (Pages 277,294.) 



29. Fostite has proved injurious to the foliage of apples, blackberries, 

 dewberries, forcing cucumbers and forcing musk-melons. (Pages 294, 

 295, 296.) 



30. When dry, fostite possesses no value as an insecticide which kills 

 by contact. (Page 296.) 



31. Neither borax, nor boracic acid and lime appear to possess any 

 fungicidal value. ( Page 296.) 



32. The application to the foliage of dissolved iodine crystals is 

 unsafe and of doubtful value. ( Page 297.) 



33. Nitrate of soda, when applied in water, has a caustic action upon 

 foliage, and it possesses apparenily no fimgicidal properties. (Page 

 297.) 



34. Caustic potash may have some fungicidal value. ( Page 298.) 



35. Abretic acid, and also kreolin, were applied for fungicidal pur- 

 poses but no beneficial results followed their use, (Page 298.) 



36. Antinonnin must be kept moist, else it becomes a dangerous sub- 

 stance to handle. (Page 299.)
