SARE Farmer Grants for 2023 – Webinar on October 4th

Truck spreading fertilizerMultiple Northeast SARE (Sustainable Agriculture Research and Education) grant recipient Tommye Lou Rafes, of T.L. Fruits and Vegetables in West Virginia, is sharing her experiences to help other farmers experiment with new ideas through the Farmer Grant program.

At noon on October 4th, 2022, Rafes will join Northeast SARE Grant Coordinator Candice Huber for an informational webinar to assist farmers interested in applying for up to $30,000 in funding for projects beginning in March 2023. Registration is required and participants are encouraged to submit questions ahead of the event. The Call for Farmer Grant Proposals is currently available and the online system for submitting applications is opening soon. Applications are due November 15, 2022.

Northeast SARE Farmer Grants are perfect for farmers looking to grow through new practices. Rafes first learned about SARE while attending a Good Agricultural Practices (GAP) training. One of the professors hosting the meeting was a SARE reviewer who invited the attendees to apply for a grant. Rafes knew sustainable practices like using renewable-powered high tunnels to extend growing seasons could be good for business as well as the planet. “Growing in the winter months is a completely different way than you do in the summer months,” she said. “I decided to test varieties that were successful during the winter months as well as growing conditions that could be improved so that people would be more successful.”

Grant Coordinator Candice Huber says Farmer Grants are an opportunity for farmers to try things that could improve their operations. SARE funds can cover the farmer’s time on the project, any farm workers time spent on the project, supplies that are not capital purchase, technical support, soil testing and other budgeted items. Farmer grant projects generally are for one year.

If you have an idea and you need resources to really explore it, a Farmer Grant can connect you with those resources. This webinar will be a good starting point and participants must pre-register. See below.

To sign up for the October 4th webinar at 12:00PM go to https://us02web.zoom.us/webinar/register/6516611235851/WN_RoG_IkMmSDGsduZwmFgKkA

Hairy Galinsoga: Non-Herbicide Management Options in Specialty Crops

Hairy galinsoga spreads throughout a farm by seeds that germinate quickly once exposed to light, with multiple generations in a growing season.  Using knowledge about the life cycle of this weed is important when making management decisions that require time and effort throughout a growing season. Learn more about non-herbicide management methods to control hairy galinsoga populations on your farm by using the hairy galinsoga decision tool fact sheet and a companion presentation.  These resources are one of a five-part weed management series created by Extension Specialist Thierry Besancon and County Agricultural Agent Meredith Melendez, funded by USDA Specialty Crop Block Grant AM190100.  You can provide feedback through an online survey about these resources.Hairy galinsoga

Cucurbit Downy Mildew Alert – 9/16/22 – Pumpkin and Butternut Squash

Cucurbit downy mildew has been confirmed on pumpkin and butternut squash in New Jersey. Cucurbit downy mildew was confirmed on summer squash in southern New Jersey a few weeks ago and cucumber earlier this season.  Remember, some CDM isolates fall into Clade I which predominately infect watermelon, pumpkin, and squash, where other CDM isolates in Clade II predominately infect cucumber and cantaloupe. All cucurbit growers should scout on a regular basis and initiate a weekly CDM fungicide program.

Vegetable IPM Update 09/14/22

Note:  Insect trap data are unavailable from much of southern New Jersey this past week due to staff shortages.  No maps will appear in this edition.  Maps will resume later in September as conditions permit.  Interpretations from available data will continue in the absence of maps.

Sweet Corn

European corn borer (ECB) moth catches are nearly non-existent now.   At this time, no feeding has been detected.

Hessian Fly-Free Planting Date Reminder

Grower planting small grains for ‘grain’ harvest next year should review the Hessian fly-free planting date for their area. Wheat is more at risk, rye for grain is least at risk.

High Probability of Downed Droughty Corn During Hurricane Season

The national oceanic and atmospheric agency at Colorado University has released their forecasting for the next two months of the Hurricane and Tropical Storm Season. The strong La Nina is persisting into a third year coupled with decreasing water temperatures returning closer to normal for this time of year are reportedly similar to 1999, 2000, 2011 and 2021 conditions.

Field corn: The stalk stability of droughty corn is much less tolerant to high winds than non-droughty corn. Given the drought conditions, corn producers may have the ability to harvest corn earlier than normal due to rapid dry down on the cob. Current soil moisture conditions are very suitable for fitting fields for winter small grain establishment.

Moldy cornAspergillus mold species often show up after drought conditions, posing a significant risk of aflatoxins in the corn crop if present. Aspergillus molds are carcinogenic to people and cause losses in livestock and poultry. Combine operators and elevator operators should take precautions against inhaling fungal spores. Signs of Aspergillus ear rot include evidence of powdery olive-green mold on the ear tip or on kernels in the ear.

Corn with brown spots

Fusarium ear rots are also probable in fields that had significant high humidity and high temperatures as grains are developing to black layer. Fusarium molds show up as white to pink cotton-like growths mold scattered throughout the ear. A starburst like pattern may occur on infected kernels that may also be brown in color.

*Inhaling poison ivy volitile oils and ivyleaf morning glory and jimson weed dust as they go through the combine along field edges should also be avoided.

Hurricane Season: Hurricane forecasters have stated that this La Nina and nearer to average water temperatures are similar to 1999, 2000, 2011 and last year. Given that in 1999, 11.41 inches of rain fell in Salem County; and in 2000, 5.76 inches fell in Salem County; and in 2011, 6.19 inches fell in Salem County in the month of September, producers who can harvest early may want to consider higher moisture harvest if standability is an issue. Hurricane season peaks from mid-August to mid-October with the season ending on Nov. 30.

Soybeans: Soybean fields should be walked for signs of stem snap in areas with high levels of soybean stem borer activity in 2020 and where July herbicide applications visibly stressed plants during the height of the drought this season. Due to in season stresses, bean maturity in the pods may be farther along in some fields than leaves indicate. If 90% of the beans are tan, test moisture levels frequently.
