Doug Johnson, Extension Entomologist and Sam McNeill, Extension Agricultural Engineer College of Agriculture, University of Kentucky

Before Harvest (Two Weeks)


	Storage ID: _________________

	___ /	___ /	___	Clean all equipment used to handle grain (Ex.: combines, carts, trucks, receiving pits/hoppers) thoroughly to remove old grain, trash, and debris that might contaminate the new crop. Use pressurized air/water.

	___ /	___ /	___	Remove all “old” grain from inside storage bins. Use a shovel, broom and vacuum.

	___ /	___ /	___	Check for holes and cracks in bin roofs and walls. Seal them to prevent leaks and entry of insects and rodents. (Look closely around ladders, roof vents and other openings.)

	___ /	___ /	___	Treat the interior floor and bin walls with an approved insecticide.

	___ /	___ /	___	Remove spilled grain around pits/hoppers, and storage bins.

	___ /	___ /	___	Mow, spray or remove weeds/grass/vegetation around storage bins.

	___ /	___ /	___	Treat the outside base of bins and the surrounding area with an approved insecticide.

	___ /	___ /	___	Fumigate the space beneath the perforated bin flooring.

Warning!!! Fumigation is complicated and dangerous. If possible hire a commercial fumigator.


	During Harvest/Binning

___ /	___ /	___	Clean grain.

___ /	___ /	___	Store wheat at 12.5% moisture or less. Moisture at storage time: __________________%

___ /	___ /	___	Consider applying a “Protectant” to the bulk grain mass. Do NOT apply to hot grain!!

___ /	___ /	___	Consider applying a “Cap Out” treatment on grain surface if a protectant is NOT used.


	Post Binning

___ /	___ /	___	Use “Pitfall traps to monitor insect activity. Use three traps per bin. Check traps weekly in July and August. In colder months trap for four days each month.

___ /	___ /	___	Monitor wheat temperature and moisture.

___ /	___ /	___	Operate fans any time there is an opportunity to reduce temperature or humidity.

___ /	___ /	___	Have insects identified and classified as primary or secondary feeders.

___ /	___ /	___	Fumigate IF insects are numerous enough to result in a discount or you are planning to hold the gain into the next warm season.

___ /	___ /	___	In September run fans to cool wheat to near 60^OF.

___ /	___ /	___	In October run fans to cool wheat to near 50^OF.

___ /	___ /	___	In November run fans to cool wheat to near 40^OF.

___ /	___ /	___	After cooling to near 40^OF, seal fans with plastic to prevent air movement in the bin.


	Insecticides and Fumigants Recommended for Wheat

Do NOT use malathion for any treatments. Most forms of malathion are no longer labeled for use, the product no longer provides adequate insect control, and overuse is resulting in high residue levels on some grains.

Empty Bins - applied to walls and floor: Reldan®, Storcide II^TM, Tempo®. DO NOT APPLY Tempo® TO GRAIN! - OR - Diatomaceous Earth. Be sure your buyer will accept this treatment.

(For Update See: http://www.uky.edu/Agriculture/PAT/recs/crop/recgrn/smgbin.htm)

Under Floor Fumigants - Chloro-pic®, (Can not currently be shipped), Methyl-Bromide, Phostoxin/Fumtoxin. Fumigants ARE EXTREMELY DANGEROUS!

(For Update See: http://www.uky.edu/Agriculture/PAT/recs/crop/cleanout.htm)

Protectant - applied directly to the bulk grain: Storcide II^TMand Reldan® are labeled.

(For Update See: http://www.uky.edu/Agriculture/PAT/recs/crop/recgrn/smgpro.htm)

“Cap Out” treatments applied to the top 4 inches of grain. (Do not make this application if a protectant has been applied to the bulk grain: Reldan® for beetles or Reldan® or products containing Bacillus thuringiensis e.g. Dipel®, Javelin®, Sok-B.T®. etc. for Indian Meal Moth.

Bulk Grain Fumigants - Phostoxin® / Fumtoxin®

(For Update See: http://www.uky.edu/Agriculture/PAT/recs/crop/bulkfum.htm)
