Now that Kansas wheat has headed, it is a good time for producers to get their bins ready for harvest, said Kansas State University entomologist Jeff Whitworth.

Whether storing seed wheat or the entire wheat crop, storage areas should be cleaned thoroughly and sprayed with an insecticide prior to filling with this year's harvest, said Whitworth, who is a specialist with K-State Research and Extension.

"This needs to be done several days prior to harvest so that the insecticide has time to work before new grain is put into the bin."

Growers should also make sure that any other grain stored on the farm is free from infestation prior to harvest to reduce the chance of insects from moving from one bin to another, he said. Any infested grain should be sold, disposed of or fumigated. Even small quantities of old grain can serve as the source of insects to infest this year's grain.

If the grain will be stored on the farm for more than a few weeks, producers will probably want to consider using a grain protectant to treat the grain as the bins are being filled, Whitworth said.
