THE "SPEED SPRAYER"- At the Pennsylvania Station the work of the new speed 

 sprayer was compared with that of the older conventional high pressure 

 sprayer. It was foxond that the speed sprayer deposited less lead in the 

 tops of the trees but more on the bottoms, and gave somewhat less control 

 of insects and diseases, especially with Mcintosh. However, applications 

 were made twice as fast with the same amount of labor, (proc. A.S«H«S», 

 Vol. 44, page 129). 



FERIJATE FOR CEDAR RUST . Cedar rust is not the most important disease of 

 apple trees in Massachusetts, yet it sometimes does great damage to sus- 

 ceptible varieties such as Wealthy and Golden Delicious* Experiments in 

 Virginia showed that Fermatg, l-g- pounds, plus 1 pint miscible kerosene in 

 100 gallons controlled cedar rust on both fruit and loaves almost perfectly. 

 It also proved superior to Bordeaux mixture in controlling bitter rot. 

 (proc. A.S^H.S., Vol. 44, page 107). 



SULFUR SPRAYS AND GROV'JTH . Y/e are changing from liquid lime sulfur to wetta- 

 ble sulfur largely because of a feeling that lime sulfur is injurious to the 

 trees. The RJiode Island Experiment Station has carried on a comparison of 

 various sulfur sprays and dusts including trees v/ith no fungicide. After 

 five seasons with Baldwin, the dusted trees were the larger in trunk diam- 

 eter, followed by those receiving wettable sulfur and those with no fungi- 

 cide. The Mcintosh trees receiving wettable sulfur and dust grew best, 

 while those with no fungicide were the smallest of all. This suggests that 

 Y/e may do very well if we do not spray young Baldwin trees but had better 

 not omit scab sprays on young Mcintosh. Their figures confirm the idea 

 that liquid lime sulfur does check the grov;th of trees and that a 1-50 spray 

 is worse than one of 1-100. (proc. A.S.H.S., Vol. 44, page 99). 



LEAF AREA PER FRUIT IN PLUMS « Much has been published relating to leaf 

 area and the size and quality of the fruit. EiJ^eriments in the State of 

 Washington showed that with tv/o varieties of plums, at least four leaves 

 per fruit were necessary in order to mature the fruit and to permit adequate 

 fruit bud formation for the crop of the succeeding year. A larger number 

 of leaves per fruit resulted in larger, better colored fruit, higher in 

 sugar and, therefore, of better quality. It is possible that under our 

 conditions more leaves per fruit are necessary. The regulation of leaf 

 fruit ratio is a matter of judgment. Perhaps it is safe to say that at 

 least 6 to 10 leaves per plum arc necessary under our conditions. 

 (proc. A.S.H.S., Vol. 44, page 94). 



EXPLODING THE SKIN FROM APPLES . Apples placed in a tight retort and heated 

 to 2400-2500 and then suddenly cooled by shutting off the steam and forcing 

 cold water into the retort were peeled almost instantly with little waste. 

 Potatoes were peeled and lima beans shelled by the same apparatus. A patent 

 on the process has been applied for by the Ohio state University Research 

 Foundation, (proc. A.S.R.S., Vol. 44, page 190).
