In response to requests for information about post-hurricane mitigation for producers in the Florida Panhandle, this statement is meant to serve as a starting point for farmers and Extension professionals seeking information about immediate steps to take after hurricane damage to farm operations.

  1. Document the damage. Timely, good documentation of damage is the first thing needed. Timely photos with timestamps (as soon as it’s safe to do so, before clean-up) of damage to fences, conservation structures, trees/windbreaks, irrigation systems, farm machinery, and equipment, along with estimates of yield loss (compared with historical yields), etc. will be critical for insurance and assistance claims. Yield loss can be documented if any harvest was done prior to the damage, and also attempting to harvest after the damage occurred. An affidavit may be necessary.
  2. Contact your crop insurance agent. Many cotton fields may be zeroed out while other fields may have enough cotton left to make harvest
    profitable.
  3. Contact the FSA. Your county Farm Service Agency is your first point of contact for assistance. Since available assistance and programs will vary
    by county, your county FSA will have the most up-to-date information available to you in your area. Visit them as soon as possible so that you
    know the documentation that will be required for your claims.
  4. Attend a Disaster Assistance Information Meeting. These are scheduled by the FSA for the following counties:

    • Washington County – November 6, 2018, 9-11 a.m.
      First Baptist Church Sanctuary
      1300 South Blvd, Chipley, FL 32428
    • Jackson County –  November 6, 2018, 2-4 p.m.
      Jackson County Extension Office
      2741 Penn Ave., Marianna, FL 32448
    • Calhoun County – November 7, 2018, 9-11 a.m.
      Rivertown Community Church Sanctuary
      19359 SR 71 North, Blountstown, Florida 32424
    • Gadsden County – November 7, 2018, 2-4 p.m.

To Dig or Not to Dig: Optimizing Peanut Digging Decisions in the Presence of Leaf Spot Defoliation

To Dig or Not to Dig: Optimizing Peanut Digging Decisions in the Presence of Leaf Spot Defoliation

When it comes time to dig peanuts at the end of the growing season, many things influence how many pods make it into the basket. Research by Dan Anco and collaborators has documented two things which can decrease yield, over maturity and disease. Though slightly different, both have the potential to weaken pegs and increase pod loss, and both can be influenced by late season rains and delayed field access. In the past, Virginia type peanuts have characteristically exhibited more of a tendency for pod loss due to over maturity than runner varieties.  The same appears to be the case when looking at losses due to late or early leaf spot diseases. While late and early leaf spot have some differences, they both cause lesions and can defoliate canopies.

To reevaluate the role of leaf spot diseases and yield loss, researchers at the University of Florida teamed up with scientists across the southeast and in the Virginia-Carolina regions to pool together data and conditions from many years to look at two common questions: How much loss occurs with different amounts of leaf spot infection?, and Is there a disease threshold where we might consider digging a field early?

Each situation can be somewhat unique, but based on their research, the team was able to develop some rough rules of thumb.  Mature runner type losses became significant after approximately 30% of the canopy was defoliated due to disease, whereas mature Virginia type losses became significant when 25% or more of the canopy was shed.  For the second question, if a field is not yet at optimal maturity, it appears that when Virginia types pass 40% defoliation, they generally tend to increase losses (due to defoliation) faster than maturity is improving or yield is increasing in an otherwise healthy field. While it doesn’t look pretty, runner types appear to be able to sustain up to 50% defoliation while waiting on optimal maturity before losses increase more than the yield gains from additional maturity. In other words, if the crop is not mature there is a critical threshold (40% for Virginia types and 50% for runner types) where yield losses due to defoliation will outweigh any further improvement in maturity.

As a reminder, if you are thinking about making a fungicide application to prevent end of season defoliation, and to help maintain the integrity of stems and pegs, be sure to check the preharvest interval (PHI) on the label of any fungicide you are considering to apply.  Do not apply the fungicide if you are not able to wait until after the PHI has passed to harvest.

Digger operation and setup is important during every harvest, but is particularly important if field conditions include sizeable leaf spot defoliation or over maturity. In another set of studies, we have seen above ground digging losses to be significantly impacted by conveyor speed. To assist with digger conveyor speed setup, a calculator is available at the link below.

Tropical Storm Gordon’s Impact on Cotton and Peanuts in Escambia and Santa Rosa Counties

Tropical Storm Gordon’s Impact on Cotton and Peanuts in Escambia and Santa Rosa Counties

Cotton laid down in the field by Tropical Storm Gordon.

For most row crop growers in Florida, Tropical Storm Gordon had minimal impact.  However, in the westernmost part of the state, much of the cotton suffered significant damage.  Though the winds were not extremely strong, the combination of saturated soils and winds wreaked havoc on what had looked like a stellar cotton crop.

The western Panhandle had been blessed with ample rains throughout the summer.  Prior to T.S. Gordon making landfall on September 3, many farmers were excited about the prospective yields for their 2018 cotton crop.  In northern Escambia County, farmers reported rainfall ranging from 7-11 inches.  Though the area did not receive a long period of high winds,  the combination of waterlogged soils and wind caused a great deal of lodging in cotton that was nearing full maturity almost ready to be defoliated.  Canopies heavy with loaded bolls and wet leaves laid down on damp soil and have not since righted their position.  The bolls touching wet ground have rotted off the plant.  The plants are matted throughout the field.   Many farmers have shared their concerns with the difficulty of defoliating a field that has cotton laying across the row middles.

Though the winds from T.S. Gordon died down within 24 hours, the rains continued.  It has continued to rain regularly since September 3rd.  Not only is the cotton worse for wear, but peanut harvest has been steadily delayed by the rains.  Greg Phillips, manager of Birdsong Peanuts-McCullough, said “Peanut harvest in the area has been greatly slowed by the rain.”  He estimates that around 7% of the entire crop has been harvested, whereas if the weather conditions had been favorable, 15% of the year’s crop would been harvested by this time.  He does report good grades so far, but he is concerned that further delays might cause a decline in both yield and grades.

The  Agroclimate image below shows the total rainfall in inches from August 13th to September 25th.  It is evident that the western Panhandle and Lower Alabama have received ample amounts of rain, but the story that it doesn’t tell is that all of this rainfall is coming at a time of year when conditions are generally starting to dry out for harvesting.

The image below from Agroclimate provides a good comparison of rainfall totals from the past 45 days to September 25.  The map of the southeast on the left shows the historical average rainfall for this time of year  The more colorful map of the southeast on the right shows the deviation from “normal” rainfall amounts.  In the case of late summer 2018, T.S. Gordon brought in much higher than average rainfall in the areas shaded in blue and purple.

It will take some time to know the full extent of the impact from T.S. Gordon.  Crop damage appears significant, but the full effects will not be known until after the completion of the 2018 crop harvest.

Help Feed the Hungry – The UF/IFAS Extension Peanut Butter Challenge is Underway!

Help Feed the Hungry – The UF/IFAS Extension Peanut Butter Challenge is Underway!

Donate jars of unopened peanut butter to your County Extension Office for delivery to local food pantries. Paul Davis, 4-H youth development agent, and Julie McConnell, horticulture agent, both with UF/IFAS Extension Bay County, stand next to their 2016 peanut butter donations.

If you want to help feeding hungry people in Florida’s Panhandle this year, you can donate peanut butter during the annual Peanut Butter Challenge, coordinated by UF/IFAS Extension.

Thanks to a partnership of UF/IFAS Extension and the Florida Peanut Producers Association, food pantries from Pensacola to Monticello will receive thousands of jars of donated peanut butter this December.

From October 1 through November 21, you can donate unopened jars of peanut butter to your local UF/IFAS Extension county office, and other drop off points in each participating county.

Since 2012, the volunteers and UF/IFAS Extension faculty have collected jars of peanut butter from residents, volunteer groups, and businesses in 16 northwest Florida counties. “Last year, UF/IFAS Extension county offices received 6,222 jars of peanut butter,” said Libbie Johnson, agricultural agent for UF/IFAS Extension Escambia County and co-organizer of the Challenge.

In addition to these donations, the Florida Peanut Producers Association also contributes, supplying more than 3,000 jars each Challenge,” Johnson said.

The Peanut Butter Challenge not only raises awareness about the important contribution of North Florida’s peanut growers to the state’s peanut industry, but also helps provide a healthy, locally produced product to food-insecure families in Northwest Florida,” Johnson said.

Check out the YouTube video produced to share the importance of this nutritious food for local food pantries.
