The following harvest and storage management tips for dwarf bunt infected fields can help increase sample quality:
Cut high with the combine
Wheat infected with dwarf bunt will be substantially shorter than healthy plants. Raising the header will reduce the amount of bunt balls harvested.

Rain! Rain! Go away and come back another day (preferably June, July and August)! At this time it would be premature to switch from adapted hybrids to shorter season hybrids. When field conditions delay planting and necessitate switching to less than full-season hybrids, factors to consider in this ... Continue reading
Trap counts sent in to the network this week from last week’s moth catches indicate that moth flight increased dramatically. And from tweets on Twitter and emails coming in from participants, even higher numbers are being caught this week in some traps. So we haven’t quite reached peak moth ... Continue reading

Western bean cutworm - Hot spot egg mass locations continue to be in the Bothwell area with now fields in the Tillsonburg area also showing up wit... Continue reading
There are a few fields in the Bothwell/Cairo area that are already above threshold for western bean cutworm. The fields we are finding most of the eggs in are those that are the most advanced in growth stage for that area. The fields we have found eggs in so far have all been transgenic corn fi...
