- •愛荷華州中部與東部部分地區降雨過多，而西北部與中西部則面臨嚴重乾旱。
- •Witt 表示，隨著收穫臨近，濕潤與乾旱地區都可能出現莖腐問題。
- •他建議農民逐田檢查，並在決定收穫時機時重視莖稈強度。
- •Witt 指出，收穫決策不應只依賴播種日期、相對成熟度或日曆。

為變動不一的收穫做準備。
Wyffels Hybrids 區域農藝經理 Mike Witt 表示，本季玉米帶各地的墒情差異很大。
“Being around central Iowa and into eastern Iowa, there’s been a lot of rain, sometimes too much. But if we trend up to northwest Iowa and into west-central Iowa and places like that, we’re in a fairly severe drought.”
隨著收穫逼近，Witt 告訴 Brownfield，莖腐可能在濕潤與乾旱地區都成為問題，因此逐田巡查比依賴固定時程更重要。
“It can be different stalk rots, but at the end of the day that stalk integrity is really, really important. So for me if I’m looking at the dryer conditions, I have to look at which of my fields are standing. It cannot be a decision that’s based solely on planting date (or) solely on relative maturity. You can’t go by the calendar, you have to just go out and take it out.”
