1. Field Observations

The Update is a day early again this week, so here is the drought map from JUNE 8th. Most of us received about an inch (or more) of rain this week and are expecting more over the next 10 days. That's some welcome news because our hayfields and pastures have a lot of catching up to do….

2. Growing Degree Days (See: Climate Smart Farming Growing Degree Day Calculator)

Growing degree days (GDD) are calculated by taking the average daily temperature and subtracting the base temperature for development of a given organism ((High + Low)/2 - base temp = GDD). For corn silage, we are using base 50/86, as corn development starts at 50 degrees F and ceases above 86. Check your location and planting date:

3. Pest and disease monitoring

Cereal Leaf Beetle

Be on the lookout if you've had problems in the past. Numbers are increasing each year, all over the state.

Potato Leafhopper and Alfalfa Weevil

We are seeing only very few leafhoppers (far, far below threshold), but we are still seeing alfalfa weevil damage and larvae in fields. However, the larvae are reaching their 4th and final stage before pupating in much of our region. They cause their worst damage in this stage, but spraying to control them at this advanced stage is likely not economical, especially if your stand is 16" or taller. But you may see a return if you're in a higher elevation area (cooler climate, which means the weevils will be in their earlier growth stages), your stand is at least 50% alfalfa, shorter than 16", and you're seeing damage on 50% of the alfalfa stems in your field. 

Black Cutworm (BCW) and True Armyworm (TAW)

Numbers are still low this week, but I have seen some (very sparse) cutworm damage in our region. So continue to check your fields until V6 (~12") for cutworm damage.

Fusarium head blight in winter grains

As winter grains begin and continue to flower, now would be the time to decide whether to protect crops from fusarium head blight. According to the Fusarium Risk Tool, the 6-day risk forecast in our region is increasing:

Winter wheat heads have emerged from the boot nearly everywhere and many are now flowering (yellow anthers visible) in fields across New York State. This is a critical time for making a fungicide spray decision. The fungicide products Caramba, Miravis Ace, Prosaro, Prosaro Plus, and Sphaerex are each labeled on wheat in New York and are effective in suppression of Fusarium head blight (FHB) and deoxynivalenol (DON) mycotoxin contamination. An application of these fungicide products should be based on FHB risk as well as the risks of powdery mildew, rusts, and fungal leaf blotches in the upper canopy based on scouting of individual fields. There is an application window of approximately 7 days starting at beginning of flowering in which reasonable FHB and DON suppression can be expected. Though the calculated risk of FHB infection is currently low due to dry conditions, the risk level may change in following days. Also consider microenvironments near lakes, in river valleys and next to woods that tend to have persistent dew, and other fields that have a history of mycotoxin contamination. Check the Fusarium Risk Assessment Tool and your local weather forecast frequently.

Cash Rent and Custom Harvest Survey

To date, there is limited information available about rental rates and fees for crop harvesting.  Farms can use this valuable information for their farm business planning to help improve decision making and profitability. 

The data that is collected, and the subsequent reports/findings/resources will be helpful for all of us to answer that call of "What's the average rental rate in my area?" and "How much do people charge to combine oats?"

Take the survey here.

Farmers Can Join MeatSuite For Free! is a free resource provided by Cornell University where NY meat farmers can create a farm profile and list their bulk (wholes, halves, quarters) and bundled (i.e. Grilling Bundle) meat products.

Why should farmers join?

1. It's free and easy!
2. Connect with more local customers. In the past year the farm directory had 8,300 visits from New York consumers. Farm profiles get as many as 25 views per month from potential local customers. We also spotlight MeatSuite farms on social media and bring attention and purchases to farms through highlights and giveaways.

How do I join?

Farmers can visit to create a free farm profile. You must list at least one product for your farm's profile to go live. You'll also have access to Cornell's free Meat Price Calculator, a helpful tool for pricing your meat to make a profit.

While you're on MeatSuite, check out the "Creating Consumer-Friendly Bulk Meats" publication on the log-in page. It has tips on how to create bulk meat products that are easier for first-time buyers to say "yes" to.

If you have any questions as you create your farm profile or products, we're here to help! Please email Matt LeRoux at

Spotted Lanternfly

Lycorma delicatula, or Spotted Lanternfly (SLF), is an invasive plant hopper from Asia and is an agricultural pest. In the United States, it was first found in Pennsylvania in 2014. Spotted Lanternfly has been found in New York State on Staten Island, all New York City boroughs, Long Island, Port Jervis, Sloatsburg, Orangeburg, Ithaca, Binghamton, Middletown, Newburgh, Highland, and the Buffalo area. SLF threatens the agriculture and forestry industries, and is also a nuisance pest. The nymphs and adults feed on over 70 different plants, but is especially detrimental to grapes, a black walnut, hops, maple trees and apples. New York State Ag and Markets supported CCE efforts to help bring awareness to communities and we developed this Public Service Announcement and would appreciate you sharing it with your member lists.
