46 ' EXPERIMENT STATION BULLETIN. 



SLMMARY OF RESULTS OF EXPERIMENTS WITH CURRANTS 



Disease Resistance. Varieties of currants vary in their resistance to 

 anthracnose. According to observations made in 1919, Prince Albert is 

 very resistant and London Market is resistant. Wilder, Perfection, 

 Fay's Prolific, La Versailles, Cherry and Red Cross may be classed as 

 susceptible and Red Dutch as very susceptible. 



Foliage Injury. The foliage of all plants sprayed with bordeaux was 

 in excellent condition at all times. Sulphur dust and dilute lime-sul- 

 phur caused severe foliage injury. 



Disease Control. Bordeaux gave excellent control of anthracnose on 

 all varieties. Sulphur dust and dilute lime-sulphur did not give satis- 

 factory control, especially with the more susceptible varieties. 



Results with Arsenicals. Lead arsenate, calcium arsenate nor mag- 

 nesium arsenate used in combination with dilute lime-sulphur caused 

 any foliage injury. 



Insect Control. As there was no insect injury on the check plants 

 no comparison can be made of the different materials used.
