EXPERIMENTAL FARMS. 



" "With regard to the plum wood, inoculated by myself the early part of this month, 

 with the Fungus, I (as I reported) obtained a good growth. The Fungus simply pene- 

 trates the surface layers and remains quite superficiaL It has attacked most of the 

 insects, but occasionally one is noted not attacked. Growth ceases when the wood is 

 dried.

Bbah Anthracngsb. 



(CoUstotrichium Lindemuthianum, Sacc.) 



This serious disease affecting bush beans was treated of in the annual report for 

 1892, and again in 1894. It was again very prevalent the past season. In previous 

 report* soaking the seed in copper sulphate 1 oz. to 2 gals, of water, and spraying the 

 plants subsequently with Bordeaux mixture was recommended. In the following table 

 the results obtained from soaking the seed of Early Mohawk in various substances — 

 most of them germicidal in character — are submitted. It will be seen that Lysol in the 

 proportion of 1^ pound to 100 pounds of water gave exceedingly satisfactory results ; 

 four per cent only, of the pods being spotted when this substance was used. Formalin 

 was also exceedingly satisfactory, standing second in order of efl&cacy. There is little 

 to choose between the three solutions of this substance used. Potassium sulphide, a 

 well-known germicide, stands third in order of efficacy. Nitrate of soda, corrosive sub- 

 limate and kainit follow in the order named. The two latter do not show marked ger- 

 micidal qualities. If further trials with this substance should corroborate these results, 

 Lysol should then supersede copper sulphate as a preventive of bean anthracnose, as the 

 results obtained here are much more satisfactory than those obtained in the former expe- 

 riments with copper sulphate.
