Grapes

Grapes Grapes are thought to have been first cultivated more than 7,000 years ago near present-day Iran. New York ranks third in wine and grape production in the U.S. (California and Washington are the top two). The 2012 Census of Agriculture reports that there are about 1200 farms with about 36,000 acres of land dedicated to grape production in New York State. Greater than half of these farms produce grapes on less than 25 acres. Eastern New York, a relative newcomer to commercial grape production, has 650 acres under cultivation.

There are four major wine producing regions in New York (Lake Erie, Finger Lakes, Hudson Valley, and Long Island). These areas are officially recognized by the Federal Tax and Trade Bureau. Improvement in cold hardiness of grape cultivars and increased consumer interest in local wine production has allowed wine trails in non-traditional grape regions to flourish (e.g. Lake Champlain Region). A small amount of acreage is even being devoted to table grapes.

The total New York grape crop value was estimated at $52.3 million at the time of the census. Grapes processed into juice accounted for 62% of the total production, with the remaining 36% and 2% going to wine and fresh market respectively.

Bird Damage in Tree Fruits

Anne Mills, Field Technician
Eastern New York Commercial Horticulture

Last Modified: February 27, 2017

Frugivorous birds impose significant costs on tree fruit growers through direct consumption of fruit and
grower efforts to manage birds.We documented factors that influenced tree fruit bird damage from 2012
through 2014 with a coordinated field study in Michigan, New York, and Washington. For sweet cherries,
percent bird damage was higher in 2012 compared to 2013 and 2014, in Michigan and New York
compared toWashington, and in blocks with more edges adjacent to non-sweet cherry land-cover types.
These patterns appeared to be associated with fruit abundance patterns; 2012 was a particularly lowyield
year for tree fruits in Michigan and New York and percent bird damage was high. In addition,
percent bird damage to sweet and tart cherries in Michigan was higher in landscapes with low to
moderate forest cover compared to higher forest cover landscapes. 'Honeycrisp' apple blocks under
utility wires were marginally more likely to have greater bird damage compared to blocks without wires.
We recommend growers prepare bird management plans that consider the spatial distribution of fruit
and non-fruit areas of the farm. Growers should generally expect to invest more in bird management in
low-yield years, in blocks isolated from other blocks of the same crop, and in blocks where trees can
provide entry to the crop for frugivorous birds.

Bird Damage Q&A

Anne Mills, Field Technician
Eastern New York Commercial Horticulture

Last Modified: February 27, 2017

Is it OK to deploy kestrel nesting boxes in areas where there are red tail hawks?
Yes, we deploy boxes where there are red-tailed hawks. RTHAs are essentially everywhere so we can't avoid areas where they live.

Can a person raise and distribute American kestrels?
There are likely all types of regulations about this type of thing, if it's even possible, given that kestrels are protected by the Migratory Bird Treaty Act.

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
