With 80o days and 60o nights, combined with low humidity, now is a prime opportunity to begin lowering the temperature in your wheat storage bins. Since the growth, reproduction, feeding and movement rates of insects are all governed by temperature, lowering your grain temperature will only help control stored product insect infestations. Certainly we will still have plenty of warm days left before truly cold weather sets in. Nevertheless, starting to lower stored grain as early as possible will simply aid in reaching that point were insect infestations can no longer continue to increase and cause damage.
