Soybean aphids can cause significant damage and lower yield potential on their namesake crop. It’s no surprise, then, that soybean farmers will spray for peace of mind and ‘insurance’ when even a few of these bugs are sighted.
Soybean aphids in Nebraska usually reach the economic threshold and require treatment in late July through August. Treatment during this period usually is enough to keep aphid populations from resurging before they leave the fields in late August and early September.
With the improvement of soybean genetics and commodity prices, odds are farmers are producing more soybeans — and on better ground — than they did 10 years ago. This increased profit potential brings with it a new agronomic challenge related to crop rotation.

Improved moisture projections apparently weighed on the soy complex. Soybean and product futures bounced in late July as the Corn Belt dried out, since arid August conditions can significantly reduce the fall bean harvest. However, the return of rain to short-term forecasts alleviated those concerns, while traders cited slippage in basis quotes. That triggered renewed CBOT selling as well. September soybean futures fell 26.25 cents to $10.735/bushel as Friday’s pit session ended, while November futures tumbled 23.5 cents to $10.585. September soyoil slumped 0.62 cents to 35.54 cents/pound and September soymeal dipped $6.2 to $355.8/ton.
