At harvest place new crop wheat into clean bin with sides and floors being treated with Diacon IGR PLUS, PBO-8 Synergist and Centynal EC.
Turn on fans after bin is full to remove field heat from the grain keeping it from spoiling.
Two to three weeks after harvest pull core from the bin.
Thirty to forty days after harvest (before corn harvest) turn wheat into another empty bin. Be sure bin is clean and has been treated with Diacon IGR PLUS, PBO-8 Synergist and Centynal EC.
Then turning the bin into the other bin add phosphine pellets or tablets at a rate of 90 tablets or 300 pellets per 1,000 bushels. Be sure to calculate the rate at which the grain is turning to be sure that the bin is treated equal throughout.
Be sure that the fan is properly sealed up along with vents to prevent any gas from escape.
Place warning signs on all doors and near the ladder.
The bin should remain under fumigation for 4 – 5 days.
After 4 or 5 days the fans should be turned on to start removing the remaining gas from the grain. Run for at least 48 to 72 hours straight before turning off.
Once the nights start getting cooler, the fans should be turned on again to start cooling down the grain. The fans should be turned on every night until the grain reaches 55 degrees. Insects do not reproduce at temperatures below 55 degrees.
Periodically spray around outside of bins to prevent insects from migrating into the bin from the outside. Also be sure to keep all spills picked up around the bin.
