potatoes and tomatoes. Most of these lines have good fruit size and shape. 

 The more resistant Hnes which have the most desirable horticultural char- 

 acters will be selected for further trial and increase.

Propagation of Woody Plants 



Two types of propagation beds have been tried, one under shade in a 

 greenhouse and the other an outdoor bed shaded with burlap. The latter was 

 tried as an inexpensive propagation method. Both beds were supplied with 

 constant mist by spray nozzles. The indoor bed gave a higher percentage of 

 rooting, but the outdoor one gave indication of being useful, especially with 

 a new type oil burner nozzle tested late in the season. 



Limited tests with cuttings of other kinds, such as new Rnbus crosses 

 and those of hazel-filbert, gave indication that constant mist is a good 

 method for rooting these plants. 



With sugar maple cuttings, a total of 190 rooted out of 1152 planted. 

 The rooted cuttings were potted in soil and stored in an outdoor bed cov- 

 ered with sawdust. Considerable winter-killing was noted the following 

 spring (1954). All but a few failed to survive.

New Organic Fungicides Show Promise for Disease Control 

 under New Hampshire Conditions 



Sulfur is being replaced by new organic fungicides for control of apple 

 scab because they give more effective control and better fruit finish. Phygon 

 has given excellent scab control, but sometimes causes injury to both foliage 

 and fruit. Captan and glyodin have given good scab control and excellent 

 fruit finish. Several phenyl mercury formulations have proved effective in 

 precover sprays as "eradicants", but they tend to delay ripening. 



Maneb gave the best control of potato late blight in 1953, followed by 

 nabam plus zinc sulfate, dichlone, and captan. 



Neither captan nor ferbam increased the yields of low-bush blue- 

 berries in 1953. However, the dusted foliage appeared healthier than the 

 untreated plants.

Virus Diseases of Strawberries in New Hampshire 



Preliminary studies suggest that cultivated strawberries and wild 

 strawberries growing near them are rather generally virus-infested, even 

 though no marked foliage symptoms are evident. It is probable that the 

 viruses reduce both runner formation and yield.

Effective Materials and Methods for Composting 

 Sawdust and Other Wood Wastes 



Experiments on composts of sawdust and shavings were continued. Re- 

 sults on yields of various crops grown in mixtures of these composts with 

 soil, as compared to those grown in soil only, showed again that hen manure 

 or green vegetation, or both, were good composting aids for wood wastes. 

 Sewage sludge was of doubtful value in this respect. Krilium as a soil con-
