Volume 13 Number 23

 View from the Field

The growing season is coming to a close and we have reached the end of our 13th 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 posting 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 for sharing field observations this season!

Weather Outlook – October 16, 2014

Jessica Spaccio 

NOAA Northeast Regional Climate Center, Cornell University

Last week temperatures ranged within 2 degrees of normal. Precipitation ranged from 1/10 of an inch to one inch.  Base 50 growing degree-days were less than 30 for most of the state.

 Cloudy, cloudy, cloudy.

Today will be cloudy with showers off-and-on in eastern and central NY while rain is continuing for eastern and northern NY (1-2” possible in these areas with isolated thunderstorms) and highs in the mid 60’s to low 70’s.  Lows will be in the upper 40’s to mid 50’s. Friday will be another cloudy day, only slight chance of showers for most areas with highs in the 60’s and lows in the 40’s. Saturday highs will be in the mid 50’s to mid 60’s with scattered showers as a cold front moves across the state. Overnight temperatures will be in the mid 30’s to low 40’s. Sunday there will be a possibility of showers with temperatures much cooler in the mid 40’s to low 50’s.  Overnight temperatures will be in the 30’s with frost and freezes possible. Monday will be mostly cloudy with highs in the 50’s.  Overnight temperatures will be throughout the 30’s. Tuesday will be mostly cloudy with highs in the low to mid 50’s.  Lows will be in the 30’s. Wednesday’s highs will be in the upper 40’s to mid 50’s.  Lows will be in the 30’s. The five-day precipitation amounts will range from 1/10 ” to around 1”.  The 8-14 day outlook (Oct 23-29) is showing above normal temperatures and below normal precipitation most of the state. The abnormally dry area covering the Catskills and southern Hudson Valley has persisted and expanded north and west with a smaller area of moderate drought around Ulster and Orange counties.

Storing grain…Remember Pests!

Ken Wise, NYS IPM

Do you have plans to store your soybeans and grain corn harvest on the farm?  If so CLEAN your storage bins before loading grain into the bins. Sanitation is the key to keeping insect pests out of your stored grains. The following is a step by step method for IPM in stored grain:

1.   Clean grain handing equipment (augers, combines, wagons, scoops, and trucks).

2.   Clean inside the grain bin (remember to clean under the false floor). Mice, moths, weevils and much more can survive under the false floor.

3.   Clean around the outside of the grain bin. Remove all weeds, spilled grain and debris 6 to 10 feet from around the grain bin. This will remove all habitats that can support a grain bin pest problem.

4.   Seal all cracks and crevices. Cracks are prime locations for insects to enter grain bins.

5.   Cover fans when they are not being used. Insects can enter the grain bin this way also.

6.   Use a registered sanitizing insecticide spray in and around the structure after cleaning.

7.   Never store new grain with old grain.

8.   Dry the grain bin before adding new grain. Insect pests need moisture to survive.

9.   Level the surface after filling the grain bin. Moisture accumulates in a grain peak.   Microbial activity in the wet area will heat up and attract secondary insect pests.

10. Do not fill grain bin all the way to the top. Leave a few feet for aeration.

11. Aerate the grain to at least the ambient temperature. The hotter the grain gets the faster insect   pests can develop. Stored grain insect pests development slows when the temperature falls    below 500 F.

12. Monitor grain for insect pests every 20 days from spring till fall and every 30 days in the winter.

13. If you discover an infestation of insect pests you may consider an insecticide application. Select   a NYS registered product for your stored grain. READ THE LABEL.

14. Keep areas around grain bins mowed to limit rodent hiding places.

Common Insect Pest of Stored Grain

Granary weevil Rice weevil
Saw tooth grain beetle Indian-meal moth adult Indian-meal moth larvae
Red flower beetle Flat grain beetle
Larger cabinet beetle Angoumois grain moth
Lesser grain borer Confused flower beetle

Clipboard Checklist

Keith Waldron, NYS IPM

General:

*Walk fields to check general field condition, weed or other issues

*Watch for crop maturity, stand assessments, weed escapes, lodging issues

*Keep notes on field issues while harvesting

Alfalfa:

*Evaluate established legume stands for stand viability, weed and disease issues

*Evaluate established alfalfa stands for signs of root injury in counties known to have alfalfa snout beetle.

Corn:

*Monitor fields for maturity, standability, late season insect issues, foliar diseases, ear damage and ear molds, vertebrate damage

* Monitor for weeds, note presence of “who”, “how many” and “where”

* Prepare storage areas to accept upcoming silage and grain harvest

Soybeans:

*Conduct late-season evaluation for diseases, weed issues, vertebrate damage

*Monitor for late season infestations of Brown Marmorated Stink Bug around field margins

Pastures:

*Check crop growth

*Review/Plan rotation system

*Check and mend fences as needed.

*Invasive species, plants harmful to livestock

Storage:

*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:

*House and stable fly populations can increase in barns as outside dwelling flies seek shelter during cooler weather. Increase vigilance to minimize fly breeding habitat

*Monitor animals and barn area for house fly, stable fly and other pest management needs including presence of rodents and birds.

*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

Equipment:

*Check and prepare equipment for upcoming harvests

*Maintain pesticide use records
