 w Soybean pods at growth stage R3 were 5 mm long at one of the four uppermost nodes with fully expanded trifoliate leaves.

 x Aphid counts and brown spot ratings were at growth stage R5 when seeds were 3 mm long in a pod at one of the four uppermost nodes with fully expanded trifoliate leaves.

 y Means were separated by Fisher’s protected least significant difference (LSD) at P ≤ 0.05 and NS indicates not significantly different.

 z Yields adjusted to 13% moisture.

trifoliate leaf at growth stage R5; "−" indicates that brown spot disease in the mid canopy was
below 1% of leaf area.
