Tufted Apple Budmoth (TABM): The first of 2 flights of tufted apple budmoth have started. Adults started to emerge in northern counties on 5/16 and in southern counties on 5/1. Although this has been a minor pest, timings are outlined below for anyone who had high populations last year. [Read more…]
Tufted Apple Budmoth (TABM): The first tufted apple budmoth adults were caught on 5/1 in southern counties. The first insecticides that target this pest will be due in a few weeks in southern counties. This has been only a minor pest during the last 6-8 years. [Read more…]

Brown Rot: Blossom infections from the brown rot fungus can occur whenever pistils are exposed and a favorable climate exists. Infections can occur during any wetting period when temperatures are between 41 and 86 °F. However, optimum conditions for infection occur with wetting and temperatures in the mid 70’s. During long wetting periods (several days or more) blossoms can be infected regardless of temperature. Generally infections that occur when conditions are sub optimal are less severe. Blossoms and fruitlets will remain susceptible until the pistil dessicates (sometime between petal fall and shuck split). [Read more…]
Peach and nectarine orchards in New Jersey continue to sustain considerable shoot death and fruit loss from constriction canker, caused by the fungal plant pathogen Phomospis amygdali. Many of our research orchards at RAREC this season had an above average number of cankers. The majority of infections that took place last fall and this past spring have girdled the shoots, resulting in dead or blighted branches. Any fruit distal to the cankers on these shoots have already fallen off or remain attached, slowly drying up and shriveling. This yield loss directly impacts your bottom line.
Breaking the Disease Cycle
Cankers on infected shoots are the source of inoculum. [Read more…]
