Organic and Sustainable Tree Fruit Studies
Plum curculio is a key pest in eastern US apple orchards, and is considered to be one of the primary pests limiting organic apple production in this region. Studies to determine the effectiveness of Native Strains of Entomopathogenic Nematodes for Plum Curculio Management are on going throughout New York State. The use of entomopathogenic nematodes (EPNs), S. carpocapsae (strain ‘NY 001’), S. feltiae (strain ‘NY 04’), and H. bacteriophora (strain ‘Oswego’), to determine their potential use as PC biocontrol agents. The infective juveniles (IJs) are native to NY, adapted to persist under NY conditions, have shown efficacy against last instar plum curculio (PC) larvae, which burrow in the soil to pupate. In ENY field trials, we applied nematode IJs of S. feltiae and S. carpocapsae to the soil surface using an ATV-mounted modified spray boom with 5 fertilizer (0010) nozzles and traveling between 3.0–3.5 mph. Applications of a 50:50 combination of S. feltiae and S. carpocapsae IJs were made to the orchard rows and row middles in four 2-row plots, at a rate of approximately 450 million total IJs/A. The use of micro-plot exposure arenas (4.5″ diameter x 5″ deep) lined with acrylic tube sleeves are being used to place PC larva assess PC emergence.

Establishment and Study of Sustainable and Organic Orchard Management Practices Using Disease Resistant Apple.
A one-acre block of apple, employing 9 newly developed disease resistant, traditionally bred through the Purdue, Illinois and Rutgers breeding program, were grafted onto G11 fireblight resistant rootstock and planted at 3’ x 11’ spacing. Trees were trained and pruned using high yielding ‘Slender Spindle’ tree architecture of 1100 trees per acre to optimize yield and reduce carbon inputs.
