variety is valuable only where other varieties cannot be grot-m because of red 

 stele. Later Surecrop, which is resistant to two races and partly resistant to 

 a third, was introduced. Both fruit and plant characters of this variety are 

 superior to Stelemaster. In fact, it looks promising as a commercial variety in 

 many sections and certainly will be where red stele is a problem. 



How can a grower protect himself against red stele? If he has no red stele, 

 he should take every precaution against bringing it into his fields. The danger 

 of spread from nearby sources is slight unless there is actual drainage from an 

 infested field or contaminated cultivation implements are used in a disease free 

 field. 



The real danger lies in the setting of infected plants either from nearby 

 or distant sources. Too much emphasis cannot be placed on the desirability of 

 obtaining disease free planting stock. It should be easy to obtain clean stock 

 but because of the ignorance, indifference or carelessness of some nurserymen, 

 infected stock is shipped too frequently. Recently several cases have been 

 noted where red stele suddenly appeared in previously uninfested areas which 

 could not have occurred except from the setting of infected plants. It pays to 

 know about the source of planting stock. 



If red stele has already been found on susceptible varieties, the grower 

 can either stop using the field for strawberries or he can try a resistant 

 variety. If any of the varieties resistant to one race of red stele became 

 infected, then it's grow Stelemaster or Surecrop or quit growing strawberries. 



The question is frequently asked, isn't there some soil treatment which will 

 keep red stele under control. There are two soil fumigants, methyl bromide and 

 chloropicrin which will reduce the incidence of red stele to 5 per cent or less. 

 These materials are very expensive both to obtain and to apply. It is very doubt- 

 ful that their use would be profitable. Many other materials have been tried but 

 none has proved satisfactory under all conditions. 



The best answer to the problem is don't get red stele. Know the nursery 

 that supplied your plants and let them know you want clean plants. Cheap plants 

 can be mighty expensive if they bring in red stele. If you get red stele, plant 

 resistant varieties or you'll probably be forced out of the strawberry business.

DARROW - A NEW BLACKBERRY 



On last September 18th the New York Agricultural Experiment Station intro- 

 duced a new blackberry variety. It is named Darrow in honor of Dr. George M. 

 Harrow who was for many years in charge of the research work with small fruits 

 at the Plant Industry Station of the United States Department of Agriculture 

 at Beltsville, Maryland. 



Darrow (N.Y. #24338) originated from a cross between N.Y. 15826 (Eldorado x 

 Brewer) and Hedrick (Eldorado x Brewer) . As tested at Geneva N.Y. it is note- 

 worthy among blackberries for its vigor, reliably heavy production, firmness and 

 good quality. There it also appeared more cold resistant than other varieties 

 and selections. Ripening starts early about with Eldorado and continues over a
