Stinkbugs<br />

Stinkbugs also have the potential to cause<br />

problems. The most common damaging<br />

species found in soybean are brown,<br />

green and southern green stinkbug.<br />

Stinkbugs often cause more damage to<br />

soybean quality than to yield loss, removing<br />

fluids from developing pods through piercing-sucking<br />

mouthparts. Stinkbugs are likely to reach peak populations<br />

in late August through early October, typically causing the<br />

most damage in mid-September. Threshold is when<br />

populations are greater than one per row foot or six per<br />

25 sweeps.<br />

The following graph shows the number of stinkbugs that<br />

were on plants before <strong>Endigo</strong> <strong>ZC</strong> was applied, and then how<br />

many remained 5-7 days and 10-12 days after application.<br />

As you can see, <strong>Endigo</strong> <strong>ZC</strong> was effective in providing good<br />

knockdown and residual control of the stinkbugs, including<br />

the difficult-to-control brown stinkbug.<br />
