ul thylene Dichloride i^jmulsion for Peach Borer Cuntrui 



Cooperative experiments conducted in Wew York, Georgia and Illi- 

 nois have shown that ethylene dichloride emulsion has several advantages 

 v-vur parw^dichlorobenzine, for the control of the peach borer, as follov/s. 

 1. It is effective in cool weather — in most of Massachusetts probably any 

 tinio during October. 2. It is safe on young trees. 3. It can be poured 

 ^r sprayed with equally good results. 4. It costs a little less than para- 

 dichl.robenzine. 



Although ethylene dichloride has n^t been tried -t the College, 

 the results obtained elsewhere seem to warrant a trial in Massachusetts*

 Rotired Refrigerr.tor Cars f^r Farm Storr.ge 



Refrigerator cars retired from service have been f-^und by gr^vi/ers 

 in Indiana and I/iichigan to make very acceptable air-and-ice-cooled fruit 

 storages. The costs to a Lachigan grov/er of setting up such a car are in- 

 toresting. The f. o. b. price was ipl75 and the costs incidental to moving 

 tho car to the farm amounted to ;p57.82. Approximately ten tons of scrap 

 iron brought $92.93, making the not cost $139.89. Tho capacity of this 

 car was 900 apple crates with provision for a maximum of 8600 lbs. of ico 

 for cooling. In 1937, this grower chilled 40 t^ns of chorrios. This enabled 

 hira to hold pickings for several days to tako advantage of the market. Fur- 

 thorm-/re, the fruit crone out in very satisfactory condition. 



Peaches were held from 14 t^ 20 days and wert in primo eating con- 

 dition when sold. From September 9 to October 5, twenty tons of cake ico 

 had bean used to chill and hold for various lengths of timo appr^xim-toly 

 2500 bushels of peaches. This control of markoting brougnt much groator 

 not returns, due to "hitting the market". 



After the peaches wore romoVod, fall apples were pli^cod in the 

 car and the remaining ice utilized. Throughout the Vi/inter, the car vms 

 operated successfully as an air-cooled apple storage. L. Southwick.

In V^ashington, it was f..und that from 14,000 to 159,100 spores 

 of various fungi per applt^ Wore present in tho :-,ir in orchards. Over 

 108,000,000 spores were averL^god on tho inside ^f six boxes. Gloves Worn 

 by sorters gave 12,000 to 40,000 spores per square inch of palm. Apples

Freeze vs. Freeze 



In recent freezing studies -t the Georgia iilxporimont Station, it 

 has boon found that fruits become more solid with decreases in temperature.
