View from the Field

We have reached the end of our 12th season of the NYS IPM Weekly Field Crops Pest Report. We would like to thank all the extension educators and field consultants for providing us with in-field observations each week for the report. Your data is critical to us providing information statewide each week on the status of pests in the field.  We will be emailing an end of the season survey to determine what impact the report has had statewide. This survey helps us fine tune the report each year. Please make any suggestions on how we might be able to improve the report.

Again thank you for all your help and observations.

Weather Outlook – October 10, 2013

Jessica Spaccio
NOAA Northeast Regional Climate Center, Cornell University

Last week’s temperatures ranged from 6 to 12 degrees above normal.  Precipitation ranged from 1 – 3 inches.  The base 50 growing degree-days ranged from 25-100. Unsettled weather for portions of the state over the next couple of days as a coastal storm lingers in the mid-Atlantic. Today will be in the mid 60’s to low 70’s.  Central and southeast NY will see partly cloudy skies and a chance of showers associated with the low pressure system moving up the coast.  The rest of the state will remain dry and partly sunny.  Tonight’s temperatures will be throughout the 40’s. Friday will be partly sunny with temperatures throughout the 60’s and into the low 70’s.  There will again be a chance of showers associated with the coastal system.  Overnight temperatures will be in the mid 40’s to low 50’s. Saturday will partly sunny with highs in the mid 60’s to low 70’s.  Lows will be in the mid 40’s to low 50’s. Sunday will be partly sunny with highs in the mid 60’s to low 70’s. Overnight lows will be in the mid 40’s to low 50’s. Monday will be partly sunny with temperatures in the mid to upper 60’s.  Lows will be in the mid 40’s to low 50’s. Tuesday will be partly sunny with temperatures in the mid to upper 60’s.  Overnight lows will be in the mid 40’s to low 50’s. Wednesday temperatures will be throughout the 60’s.  There will be a chance of scattered showers as another system moves into the area.  Lows will be in the mid 40’s to low 50’s. The five-day precipitation amounts will range from over 2” in the far southeast corner of the state outward to only a tenth of an inch in western and northern NY. Areas of western and northern NY are now in DO abnormally dry conditions.

Season finale ahead – last minute thoughts?

Keith Waldron, NYS IPM

Harvest season is upon us and it’s getting close to the time where the crops will be in the bin, bale, or tucked in for the winter. Remember the pre-season planning, early season warm up, the spring rains, planting scramble, unique field issues, growing season moments, crop successes and challenges, pest issues, equipment issues, etc.? The list goes on….

Every year is different and hopefully we’ve learned something new. While this summer is still fresh in mind it’s a great exercise to ask yourself a few key questions to review what went right and what went wrong this season… Take a few minutes to capture season highlights, lessons learned, and other facts and observations while updating your crop records and field histories. A sharp pencil is much better than a dull memory! Based on what happened this year, it’s a good bet there are at least some things you know you could do or change to improve your farm’s performance next year. 

Some questions to get started: How well did the weed control program work? Were you satisfied with the performance of the varieties and hybrids used? Were field “problems” identified correctly? Were there any new crop diseases? Were any problems only found in certain fields or areas within fields? Thoughts on why? Were areas sampled? How effective was your early warning or rapid response system – i.e. were you able to head off situations before they hurt yield or quality? Did you run into anything new or unusual? Were there any fields with yields much lower or higher than expected?  Any thoughts on why? How effective were any pest management actions taken? Did you have any side by side treatments to evaluate effectiveness of any pest (or other) management actions taken? What did you learn? Were there major successes, or do some areas need improvement? What will I do differently next year?

Documenting your crop protection decisions and their effects provides critical feedback for assessing the value and impact of actions taken and for optimizing future management decisions. Did they make or save you money?  Are there any “action items” to put on the “To Do” list to improve your pest management next season?  Which activities / actions worked well?….stick with them. Which practices were less than successful? Why?….improve them, or replace them.  Is there any new information available?….evaluate and incorporate. What’s the question(s) you will bring to the next grower meeting?

Hope these suggestions have been helpful. Ken and I have really enjoyed working on this year’s Weekly Field Crop Pest Report and hope you have found the report helpful.

We wish you a safe, bountiful and profitable harvest season! Until next year!

Clipboard Checklist

Keith Waldron, NYS IPM

*Walk fields to check general field condition, weed issues, areas of soil erosion

*Evaluate established legume stands for approximate days till harvest
*Conduct a fall stand count and weed assessment

Conduct late-season corn pests including European corn borer, foliar diseases such as northern corn leaf blight, gray leaf spot, eyespot, ear mold, weed issues, vertebrate damage
*Be on the lookout for possible larval feeding by Western Bean Cutworm in corn ears (and dry bean pods)
*Evaluate corn for possible lodging issues, determine maturity and estimated days to silage harvest

Conduct late-season soybean pests such as soybean aphid, white mold, soybean vein necrosis virus and other diseases, weed issues, vertebrate damage
*Monitor for late season infestations of Brown Marmorated Stink Bug around field margins
*Evaluate soybeans to determine maturity and estimated days until harvest

Check and mend fences as needed.
*Check crop growth
*Monitor for invasive species, plants harmful to livestock
*Review/Plan rotation system

*Check and prepare equipment for upcoming harvests
*Maintain pesticide use records

*Clean and sanitize empty grain bins in advance to receive upcoming soybean or corn grain harvest
Check forage allocation and anticipate feed program adjustments as forages from previous year are used up
*Plan where forages should be stored for optimum allocation next feeding season
*Mow around storage bins and facility to minimize harborage and pest hiding places
*Check stored grain bins for temperature, moisture and signs of mold and insects. Aerate, core, transfer grain or treat as necessary

 Dairy Cattle Barn Fly Management:
*Monitor animals and barn area for house fly, stable fly and other pest management needs including presence of rodents and birds.
*Fall is the time of year when house and stable fly populations may increase inside barns as those flies living outside seek the more attractive, relatively warmer temperatures inside.
*Check facilities for favorable fly breeding conditions: (organic matter + moisture): leaks in watering systems, roof gutters for leaks and potential overspill, drainage,
*Sanitation, sanitation, sanitation – clean animal resting areas, feed troughs, minimize source of moist organic matter i.e. fly breeding areas in barn and in adjacent animal loafing yard
* Continue fly monitoring: install “3X5″ index card fly speck monitoring cards throughout barn
*Use, replenish, replace fly management materials: sticky fly tapes/ribbons, insecticide baits, natural enemies (parasitoids), fly population monitoring (3 x 5) spot cards

 Dairy Cattle on Pasture:
*Monitor animals for presence of face flies, horn flies and stable flies. Action guidelines: face flies (average 10 per animal face), horn flies (average 50 / dairy per animal side, 200 / beef cattle per animal side), stable flies average 10 per animal (all four legs)
*Check feed bunk / water source locations for signs of stable fly breeding (moist undisturbed organic matter – spilled feed, round bales, etc.), minimize source of moist organic matter i.e. fly breeding areas in barn and in adjacent animal exercise yard.
*Check pasture for forage quality / quantity, rotate as appropriate
*Check pasture for vegetation poisonous to livestock
*Consider use of pasture fly traps to help reduce deer, horse and stable fly populations
