A comparison of the averages in Table IIT shows that potas- 
sium sulphide treatment, 1 oz. to 2 gals. water, gave the best 
results in all three series, the best result being in Series I where 
spraying was begun very early. This shows 40 per ct. less mildew 
than the check rows do. A weaker solution of the same material 
gave the next best results and here again the very early treatment 
of Series I is most favorable, being 23 per ct. better than un- 
treated. 
The results with lysol are promising, the strongest solution, 
1 oz. to 1 gal. water, reducing the amount of mildew 18 per ct. 
With formalin, the treatment in Series I, using 1 oz. to 1 gal. 
water, was much the best, reducing the amount of mildew 14 per 
ct. In most other cases the tests with formalin rank with the 
results obtained from the use of Bordeaux mixture, which in 
Series II only is better than the untreated rows. In Series I 
and Series IIT the tests with Bordeaux mixture actually show a 
larger percentage of mildew than do the check rows. With the 
exception of Bordeaux mixture in Series II the very early treat- 
ments of Series I gave the best results with all tests. 
The cost of the material for the remedy giving the best results, 
potassium sulphide, 1 oz. to 2 gals. water, is about three tenths 
of 1 cent per bush for seven applications per season.
