Our trials with ethephon usage to promote flower-bud initia- 

 tion on young non-bearing trees, large enough to bear a crop, are 

 still limited. Our preliminary data in 1973 indicate that 1-2/3 

 to 3-1/3 pints of ethephon per 100 gallons of water applied 3 

 weeks after full bloom suppressed vegetative growth on 'Triple Red 

 Delicious', a non-spur type and appears to have increased flower 

 bud formation. More data are needed, however, before we can make 

 specific recommendations concerning concentration and use of ethe- 

 phon for flower bud initiation. Until such data are available, we 

 can merely suggest that growers follow the label suggestions given 

 above for increasing flower bud development on young non-bearing 

 trees.

POMOLOGICAL PARAGRAPH 



Diuron now labeled for use under peach trees . EPA has approved 

 labeling of diuron (Karmex*) for control of annual weeds such as 

 foxtail, crabgrass, pigweed, laml squarters , ragweed, purslane, chick- 

 weed and mustard under peach trees. The best use of diuron is as a 

 tank mix with paraquat. Make a single application in mid-May of two 

 to five pounds of diuron plus one quart of paraquat with a spreader 

 per treated acre. 



Use the lower rates of diuron on lighter soils and higher rates 

 on heavier soils. Do not use this combination spray on sand, loamy 

 sand or gravelly soils, nor on soils containing less than II organic 

 matter, as injury to the trees may occur. 



The label includes the following important precaution: 

 "Use only where trees have been established in the orchard for 

 at least 3 years. Avoid contact of fruit or foliage with spray or 

 drift. Do not apply within 3 months of harvest. Do not replant 

 treated areas to any other crop within 2 years after last applica- 

 tion as injury to subsequent crops may result."
