For spraying suckers on a trial basis, mix 10 fluid ounces of 

 Tree-Hold with sufficient water to make 1 gallon of spray mixture. 

 Eight gallons of Tree-Hold are required for 100 gallons of spray. 



Control of Water Sprouts Prune water sprouts and then apply Tree- 

 Hold mixture thoroughly over the cut surfaces. It can be applied 

 ivith a paint brush or a small compressed air sprayer. We found 

 that a 1-1/2 gallon compressed air sprayer with a 12-foot hose 

 worked well, and that attaching a sponge to the nozzle was useful 

 for swabbing the mixture on pruning cuts. The treatment can be 

 applied anytime weather permits before growth starts in the spring. 

 Areas where pruning cuts have been made should be covered thoroughly 

 but drip on to other parts of the tree should be avoided. The Tree - 

 Hold mixture can kill buds . Be sure to follow the label . 



Control of Suckers Prune the suckers during the dormant season. The 

 Tree-Hold mixture can be sprayed on the stubs during the dormant sea- 

 son or when the new shoots from the suckers are 6 tol2 inches in 

 height. However, the most effective timing is when the suckers are 

 actively growing. Since the Tree-Hold mixture contains 10,000 NAA, 

 the label restricts its use from bud swell through 4 weeks after 

 petal fall to eliminate the possibility of fruit thinning and leaf 

 damage. Therefore, the Tree-Hold mixture should be sprayed the 3rd 

 or 4th week in June when the suckers are 6 to 12 inches in height. 

 Coverage should be thorough. 



The Tree-Hold mixture is too expensive to apply as a band appli- 

 cation under the trees. Since the population of suckers is generally 

 more dense near the trunk and very troublesome inside wire mouse 

 guards, the spray may be limited to these areas using a compressed 

 air sprayer, a weed sprayer with an air gun, or a weed sprayer and 

 boom with a trunk-directed nozzle.
