Lateral Branching 



Many young trees, especially spur types, fail to branch adequately. This 

 lack of branching can limit the ultimate productivity of the tree, because the 

 allotted space will not be filled. To stimulate lateral branching, Promalin 

 may be applied in the spring when terminal growth is 1 to ^4 inches long. Only 

 vigorous, healthy trees should be treated, since Promalin will not overcome a 

 lack of branching due to poor growth. The high rate of Promalin should be used 

 only on diff icult-to-branch trees. High rates of Promalin on easily branched 

 trees can stimulate too many lateral shoots, all of which will be too short to 

 develop into good scaffold limbs. Promalin should be used only on nonbearing 

 trees, because the rates required to stimulate lateral branching will thin the 

 crop the year of application and inhibit flower bud formation for the following 

 year. 



Elongate Delicious 



The Delicious grown in New England normally are not as elongated as those 

 grown in the Pacific Northwest. To elongate Delicious fruit, Promalin may be 

 applied when the king flower is open. Promalin can thin, especially if a 

 surfactant is included and the highest rate of Promalin is applied (2 

 pts/acre). Promalin should not be used on young trees until they are old 

 enough and ready to be chemically thinned.
