Thistle caterpillar, aphids, stripe rust appearing

Thistle caterpillar.

Thistle caterpillar and their webbing continue to be quite noticeable in some soybean fields, the provincial agriculture department reported Wednesday.

Aphids are at high levels in some cereal fields in the central region.

Soybean aphid has been found in some fields in the central region, but currently just at low levels.

Additional reports of stripe rust are appearing across Manitoba, with high severity showing up in fields/plots that did not receive a fungicide application. If the crop is past the flowering stage, a fungicide application is likely not warranted.
