Iowa soybean crop progressing well with warmer weather

Agriculture.com Staff 06/14/2007 @ 9:26am

Recent warm, dry weather has benefited both corn and soybeans in Iowa, which seem to be progressing well with only a few potential problems, according to a scouting report released this week by the Iowa Soybean Association.

For soybeans, one of the fields being scouted was still not planted when the consultants filed their reports for the week. Earliest planted beans had reached V5, but most were still at V1 to V2 in growth stage. There were a few reports of an increase in bean leaf beetle activity.

One consultant reported that beans needed more warmth and sunshine, which they should be getting this week. Grassy weeds, as well as a few broadleaf species, are popping up with the warmer weather, especially around field margins. Consultants expect that these will be controlled by planned herbicide applications. And volunteer Roundup Ready corn is showing up in fields of Roundup Ready soybeans.

Aphid Watch
To date, no soybean aphids have been reported in Iowa. However, entomologists in Wisconsin, Minnesota and Michigan have found them in research plots in small numbers. Growers and crop advisors in Northeast and East Central Iowa should be on alert. Keep in mind that both scouting and an economic analysis, using current insecticide and soybean market prices, are necessary to determine whether chemical control will pay.

Some purpling of corn was reported by several consultants, but warmer weather this week should take care of that. Earliest planted corn has now reached V8 growth stage. Replanted corn in drowned out areas is at V2 to V4. There was one report of hail damage in Northwestern Iowa, but for the most part, consultants say the corn is looking good, despite a few weedy areas and spotty activity by corn rootworm, common stalk borer and European corn borer.

Pre-sidedress soil nitrate tests continue to suggest additional nitrogen may be needed for optimal yields on most of the fields tested in central and southwestern Iowa.
