Improving Your Early Season Peach Brown Rot Control Program – An Update

Have you ever felt that you did everything right at controlling brown rot during the preharvest period, but still got a significant amount of brown rot at harvest?

Preparing Orchards Against the Frost – Low Tech Strategies

Frost is common in the north-eastern US, however, frost events during bloom, specifically in orchard crops can be economically devastating. Often the cause is a few hours of temperatures below the injury threshold temperature for the developing buds as cooler nights result in the rapid loss of thermal energy. Fortunately, there are several passive methods or low-tech strategies, that can help maintain a slightly higher orchard floor temperature, has the potential to prevent substantial crop loss.

Evaluate Your Wine Grape Planting Material Before Planting

Spring is the best time to plant new grapevines in New Jersey.  You may be receiving ordered grapevines in the coming days or weeks. 1You must ensure that your planting material is healthy enough to avoid problems after planting.

Tree Fruit IPM Report for March 31, 2021

Tree Fruit Phenology:

Tree fruit phenology is about normal based on historical observations. In southern counties some early blooming varieties are at Pink to about 20% bloom. Redhaven was at bud swell on March 29, about 6 days later than the median observation date. Plums are in bloom and Pears are at Green Cluster. Red Delicious is at 1/2 Green Tip, which is about a week early. So it is time to start applying delayed dormant and blossom protection applications. [Read more…]
