This issue will be the last report for the 2010 growing season. We have enjoyed creating this weekly publication and hope you have found it informative, useful and timely. Thanks to the many Extension Educators, field scouts, and industry personnel who shared their field observations and other information this season. The importance of these inputs cannot be over emphasized for their enhancements to the timely value of the report

We will soon be sending our subscribers a survey via email to solicit feedback regarding perspectives on the usefulness of this publication to your efforts and suggestions for how to improve the report next season. We hope you will take time to complete and return the survey. We take your comments and suggestions seriously and have incorporated many of your suggestions to improve the publication over the years. Thank you for your interest. Hopefully we will see you next year!

This last week I found 2 western bean cutworm moths (WBCM) at SUNY Cobleskill. I had not check this trap in about three weeks so we are not sure when the moths were captured.  In total I found 3 WBCW moths in Cobleskill this season and 1 at the Cornell Research Farm in Valatie. I also found corn ear rots at the SUNY Cobleskill last week. The corn ear rot looked like Fusarium graminearum (pink-white). Fusarium graminearum can contain mycotoxin. In the same field there were leaf lesions that appeared to be northern corn leaf blight.

General:

  • Emergency contact information ("911", local hospital, Chem. Spill emergency contact, other?) posted in central posting area
  • Maintain crop records by field, including variety, planting date, pesticides used, nutrient inputs including manure, etc.
  • Watch for any patches of herbicide resistant weeds, weed escapes
  • Storage areas cleaned and ready to accept hay, soybean, corn harvests

Field Corn:

  • Note crop growth stage and condition
  • Foliar diseases, stalk rots and ear mold
  • Check for European corn borer, Western bean cutworm, foliar diseases (such as Gray Leaf spot and Northern Corn leaf blight), vertebrate injury (birds / deer), slugs, weed escapes, herbicide injury, nutritional deficiencies, etc.
  • Monitor weed populations noting presence of "who", "how many" and "where"

Alfalfa & Hay:

  • Monitor alfalfa seedings for weeds, for potato leafhopper & diseases.
  • Check established alfalfa stands for potato leafhopper, weed and disease problems.
  • Check established alfalfa stands for signs of alfalfa snout beetle infestations in counties known to have this pest.
  • Storage areas cleaned and ready to accept next harvest?

Soybeans:

  • Note crop growth stage and condition
  • Evaluate stand for deer, weed assessment, white mold, foliar disease incidence, harvest timing

Dairy Cattle: Livestock Barn Fly Management:

  • Monitor animals and facilities for house fly and stable fly populations
  • 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
  • Continue release of purchased natural enemies (fly attacking parasitoids)

Dairy Cattle: Pasture Fly Management:

  • 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, 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 loafing yard
  • Check paddocks for forage quality / quantity, rotate as appropriate
  • Check paddocks for vegetation poisonous to livestock
  • Consider use of fly traps to help reduce deer, horse and stable fly populations

Storage:

  • Pre-clean in and around grain storage bins in anticipation of soybean and grain corn harvests.
  • Keep areas around storage bins and silos clean and mowed

Equipment:

  • Note any repairs needed for recently used equipment: tractors, tillage implements, harvesting equipment, etc. as they are cleaned and serviced.
  • Calibrate manure spreaders - maintain records on amount spread per field
