REQ Cold-Storage Plants Compared with Fresh-Dug Plants; lil; Strawlyggg-r- plants of Blakemore, Tennessee Beauty, and Ten- ` nessee Shipper dug in early winter and placed in cold storage were set in plots in early spring along with plots set to fresh dug - plants, with four replications of each. The cold-storage plants of Blakemore and Tennessee Beauty outyielded the fresh-dug ` plants by 9 crates and l4 crates per acre respectively; but fresh- dug Tennessee Shipper plants outyielded the cold—storage plants DD by 4 crates per acre. These results show that properly handled Pa cold—storage plants are as satisfactory as fresh-dug plants. Dig- E1) V ging plants in early winter is an important means of avoiding Cll crown borer, which begins to infest plants in March. Use of storage plants is also an aid to growers in getting their planting done early in the spring. T- PEACH TREE BORER CONTROL WITH SPRAYS CC J. G. Rodriguez and W. D. Armstrong pa Control of the peach tree borer is practicable in commer— cial peach orchards by appropriate spraying of the tree trunks in mh summer. This type of application provides a safe and speedy iht method of control and many growers have adopted the method lm entirely. fm ~ BQCBUSE 3. population 0f peach tree borer has such a wide variation in size, or developmental stages, and because emerge¤€€ extends apparently from late June or early July, through Septem- ber in the latitude of Western Kentucky, it was deemed important — to investigate the effectiveness of a control program utilizing two Su or three spray applications at about monthly intervals. AD €X ‘ ac 1 periment to study this point was conducted at the Western Sliatf? . I 4 l`
