Peaches

Peaches The cultivation of peaches began in China as early as 2000 B.C. The cultivation of peaches continued through the old world and was transported to the America’s where peach cultivation thrived on the east coast. By the mid-1700s, peaches were so plentiful in the United States that botanists thought of them as native fruits. Currently California, South Carolina, Georgia and New Jersey account for three quarters of U.S. peach production. New York grows over 2000 acres of peaches with more than a quarter of that located in the eastern portion of the state.

There are two types of peaches, clingstone and freestone. With clingstone peaches, the flesh “clings” to the "stone" (the pit) of the peach, making it difficult to separate. As Clingstone varieties retain their flavor and texture during processing, they are more suitable to canning and value added products.
The pit of freestone peaches separates from the flesh, making it ideal for fresh consumption. Freestone peaches are generally larger than clingstones with a firmer, less juicy texture. While most commonly eaten fresh, these peaches may also be frozen and dried.

Annual per person consumption of peaches in the United States peaked at 13 pounds in the early 1970s. By 2008 annual consumption had dropped to 8.8 pounds per person. Consumer research conducted in the mid-2000s revealed buyer frustration with mealy textures, fruit browning and lack of sweetness. This frustration has actually helped improve demand for local, NY produced peaches as there is simply nothing like a tree-ripened peach.

Over the last 20 years, Cornell research and extension projects have helped growers increase yields and fruit quality by increasing tree densities and improving labor efficiency. We estimate that profitability of new high density orchards is 100 to 300% greater than the traditional low-density orchards.

New fungicides labeled for use in tree fruit - all Special Local Needs Labels

Deborah Breth, Integrated Pest Management
Lake Ontario Fruit Program

Last Modified: April 9, 2014

The new class of fungicides, SDHI's, are now registered for use in tree fruit.  Fontelis was registered last season, and Luna Tranquility and Merivon were registered this spring.  They are all registered in NY as "Restricted Use" fungicides.  Due to the special restrictions for use in NY, they also are Special Local Need registrations.  In order to apply these materials you must have a copy of the label and the SLN label in your possession.  You can access these SLN and label to study or print at these links.

New Resources for Berry Crops

Berry Crop Diagnostics Tool - Much information exists on controlling plant pests and problems, but one must first identify the cause before intervention can occur. This diagnostic tool was developed to assist the student, grower, and extension educator in identifying potential causes of plant problems in berry crops

White Rot Update

NOW AVAILABLE: White Rot Fact Sheet: Click Here

Earlier in June I sent a garlic sample to the diagnostic lab hoping that I was wrong. The sample was covered in small black sclerotia, the size of poppy seeds, and white fungal hyphae crept up the stem. The results, unfortunately, matched the field diagnosis: White Rot. Within a couple days additional calls came from up and down the Hudson Valley as well as one in Western NY with similar suspicions. These samples have also gone to the lab for verification, but it looks like the latest pest to move back into the state is this nasty fungus. 

White Rot, Sclerotinia cepivorum, decimated the onion industry in New York in the 1930's before being eradicated through careful management. More recently, in 2003, it infected 10,000 acres of garlic in California, leading to the abandonment of some garlic fields and adoption of strict containment rules. White rot has been confirmed in Northeastern states over the last decade as well, with New York being one of the last to discover the disease.

The primary reason that White Rot is such a concern is because the sclerotia, or reproductive structures, can remain dormant in the soil for up to 40 years, attacking any allium crop planted into the soil under favorable conditions. This spring was ideal for infection due to the period of cool, moist weather we had. Optimal temperature for infection is 60-65 degrees F, but infection can occur anywhere from 50-75 degrees F.
Once garlic has white rot, it generally declines rapidly. Leaves will yellow and the plant will wilt, not unlike a severe fusarium infection. However, unlike with fusarium, white rot infected bulbs are covered in black sclerotia and white fungus. To add to the confusion, another disease CAN look similar. Botrytis also causes black sclerotia and white fungal growth. However, Botrytis sclerotia are quite large, often larger than a pencil eraser.

So, what do we do now? We're still working on long-term management strategies, but the most important steps to take now are vigilance when culling (look at the plants you are pulling for symptoms like you see in this article, and if they are present, call us to take a sample and have the disease verified) and, if you see anything suspicious, reduction of movement of inoculum. The main ways diseases get moved around are by dumping culls (compost, field edges, etc) and my moving soil on equipment. Throw away your culls, and wash equipment that may have come in contact with suspicious garlic or the soil it is growing in. Everything from cultivation equipment to harvest bins should be cleaned. 

We will keep learning about this disease and will keep sending out information, particularly to help you make decisions about what to sell and buy. For now, remember that the west coast has learned to manage the disease, and we will too. -Crystal Stewart, ENYCHP
