Naphthyl Acetamide (NAD) is a kind of synthetic auxin, used as plant growth regulators, Naphythyl Acetamide (NAD) is. 1-Naphthyl Acetamide (NAD) works by inducing the formation of an abscission zone in the plant peduncle. NAD acts as a thinning agent on various fruits such as apples and pears, NAD may also be used to help prevent premature fruit fall and as a rooting powder for several fruit crops. the benefits by applying Naphthyl Acetamide (NAD) are including:
Grower know that after a cool winter, deciduous fruit trees with low chilling requirements set a heavy load. To protect the tree from being damaged by the weight of the developing fruit, and to obtain full size fruit, it may be necessary to thin apples, apricots, peaches, pears, and plums. The earlier this is done after fruit set, the more size response will be expected in fruit remaining on the tree.
Stone Fruits: (apricots, peaches, plums, nectarines)
By the time fruit is approximately the size of a quarter, most of the unpollinated fruit will have fallen off. Remove all the doubles, damaged or misshapen fruit. Thin remaining fruit to leave one fruit every four to six inches, or no more than two to three fruits per "hanger" (small branch). Thinning to a uniform size fruit will generally give you a harvest period of about two weeks. The harvest period can be extended by leaving fruit of varying sizes. The larger ones you leave will ripen first. Peaches thined to six inch spacing
Apples and pears also need to be thinned. They form in clusters of four to seven fruits along the spurs. Cluster of apples prior to thinning
Remove all but the largest apple in the cluster. Remove all the fruit from every other spur to prevent alternate bearing (heavy fruit set one year and minimal fruit set the next.)
