Nectarine trees are fast-growing fruit trees that produce leaves and buds similar to those of peach trees and start fruit production within 3 to 5 years of planting. Like other fruit trees, nectarine trees are susceptible to infestation by pests and may require occasional spraying to keep pests from damaging the wood and fruit.
Spray for scales, mites and the fungus known as leaf curl during the dormant season of the tree, which is before buds appear on the tree in the spring. Daconil 2787 will prevent these attackers. Three sprays of Daconil can be done during the dormant season, in November, December and January.
Spray for brown rot fungus, tarnished plant bugs and green peach aphids with Daconil 2787 in the time between the tree budding in the spring and the fall of the petals from the tree. Spray the tree every 7 days until the petals fall.
Spray the nectarine tree for mites, aphids and fruit moths after petal fall, when at least 90 percent of the flower petals have fallen from the tree. Use both a brown rot fungicide, such as a DMI or BZI fungicide, and an insecticide to kill both the fungus and the pests.
Use a combination of captan, thiophanate-methyl, malthion and esfenvalerate to treat for mites, aphids, fruit moths and brown rot during the shuck split period, when the fruits split their outer husks. Spray initially 10 days after the shucks first split, again in early June and in early July.
Apply captan and thiophante-methyl to the tree approximately 1 week before the tree’s harvest. This will keep brown rot away and get rid of Japanese beetles.
Follow the directions on the label of each product that you are spraying on the tree. The label will tell you how much of the product to use at one time and the last time that the tree should be sprayed before a harvest.
