Kansas State University entomologist Phil Sloderbeck is advising Kansas wheat farmers to remember to clean storage bins and spray them with insecticides before this year's harvest begins.
Sloderbeck, who is the entomology state leader with K-State Research and Extension, said the work 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.
Producers should also make sure that any other grain stored on the farm is free from insect infestation prior to harvest. That reduces the chance of insects' 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 grain will be stored on the farm for more than a few weeks, producers probably will want to consider using a grain protectant to treat the grain as the bins are being filled, Sloderbeck said.
