A spraying experiment was conducted using the spray schedule recom- 

 mended in Special Circular 46 of the Llassachusetts Agricultural Extension 

 Service. T'his schedule controlled Brovm Rot very well, freed the loaves from 

 a 'gall maker, and probably helped in controlling Plum Pocket. However, some 

 modifications will be necessary to improve the control of other insects and 

 diseases* 



As a result of a series of propagation experiments, it was found that 

 the beach plum can be rooted from green wood cuttings taken in early June and 

 treated with a groivth promoting chemical. 67% rooting was obtained in about 

 4 weeks and plants with well established root systems were produced in 2 months. 



Plants of several selections were obtained from the Soil Conservation 

 Service and planted at the Cranberry Station at East Vifareham. These will be 

 used as foundation stock for future improvement work. 



The Department of Horticultural Manufactures showed that both the pec- 

 tin and the acid content of the bea&h plum are very near the lower limit for 

 jelly making. For. this reason, difficulty is sometimes experienced in producing 

 a firm jelly. ' V^ays of overcoming these difficulties vrere worked out and the re- 

 sults published. ___j^ g^ Bailey 



CONTROL OF PEACH TREE BOREl^ 



It is now time to do something;; about those borers in your peach trees. 

 Undoubtedly the safest procedure is to stick to the old and tried methods, 

 worming v;ith a knife and wire for trees under three years of age, and paradi- 

 chlorobenzene for trees throe years old and older. 



The ethylene dichloride emulsion treatment cannot be recommended with- 

 out reservations. Additional information and experience gained in using this 

 treatment indicate that it is reasonably safe under Massachusetts conditions, 

 if properly applied. Experiments carried on in the College orchards during the 

 past two years indicate the following} (1) A broken emulsion can cause trouble. 

 Be sure the emulsion hasn't broken. If it has, re-emulsify it thoroughly. 

 (2) Slight variations in strength or quantity of diluted emulsion will probably 

 do no harm. Vflien double the quantity was applied, injury resulted. (3) Prac- 

 tically 100^ kill of borers was obtained where the material was applied October 

 15 or earlier; kill v; as not so good after that date. (4) If the emulsion comes 

 in contact with the trunks, injury will probably result. Several yoiong trees 

 wero killed and several others severely injured by pouring the emulsion on the 

 trunks. 



To play safe, be sure the ehylene dichloride is thoroughly emulsified 



before use. Follow the directions on the container as to strength and quantity 



of emulsion, and keep the material off the trunks. For best results, apply on " 



or before October 15. j. s. Bailey
