The results are shown in Figs. 1 and 2. All the cultivars seemed to respond about the same. Our results indicated that the spray con centration needs to be at least 5000 ppm (7.85 oz of Alar/10 gallons of water) and should be applied to run-off every 7 days to keep the seedlings small. After 7 days, the seedlings resumed normal growth in all cases; thus our two sprays delayed transplanting by ]k days. We would suspect three sprays 7 days apart to delay transplanting by 21 days. The seed lings were growing in Jiffy Mix and were kept well watered in full light. After transplanting, the treated seedlings showed no effect from the application of the growth retardant other than delayed transplanting. The treated seedlings did not appear "hard" and "slow to start" as is often the case with seedlings held dry and cold.
