Recommendations For Managing Soybean White Mold In 2010, Xiao-Bing Yang

Integrated Crop Management News

The 2009 growing season had record cool weather in July that was ideal for soybean white mold occurrence. The disease was widespread in the north central region of the U.S. and agronomists even in southern Iowa observed this disease in many soybean fields. In northern Iowa, patches of soybean killed by this disease were obvious in many soybean fields along the highways. Some farmers reported losses totaling more than $10,000 from this disease.

Minimize Sds And White Mold Risk To Same Field, Xiao-Bing Yang Dec 2009

Minimize Sds And White Mold Risk To Same Field, Xiao-Bing Yang

Integrated Crop Management News

Both soybean sudden death syndrome (SDS) and white mold (WM) were wide spread in Iowa during the 2009 season. The simultaneous outbreak of soybean sudden death syndrome and white mold (SDS-WM) had only occurred once previously – in east central Iowa during the 2007 growing season. This season was the first time that the two diseases were wide spread in Iowa. Many growers experienced the occurrence of SDS-WM on the same farm, some in the same field. In one session at the Iowa State University Integrated Crop Management Conference on Dec. 3 in Ames, I polled the group to learn how ...

A Tough Harvest - Frequently Asked Questions, Update, Charles R. Hurburgh

Integrated Crop Management News

Iowa was very fortunate to receive two weeks of warmer than normal weather, and more importantly lower than expected humidity in the air. This has allowed soybean harvest to be nearly completed, and rapid progress to be made on corn harvest, with moistures now in the low 20s and upper teens. The eastern and far northern Corn Belt still have much wetter corn in the field. New problems have arisen, and efforts now turn to conditioning grain for storage.

How Delayed Harvest Might Affect Ear Rots And Mycotoxin Contamination, Alison E. Robertson, Gary P. Munkvold

Integrated Crop Management News

The corn harvest is later than it has been any time in recent memory, and the prolonged moist conditions are conducive for molds to develop on grain in the field. Over the past few days we have received numerous reports of ear rots developing in the field and questions concerning mycotoxin production when conditions are cool but wet.

2009 Corn Quality Issues – Storage Management, Charles R. Hurburgh, Roger Elmore Oct 2009

2009 Corn Quality Issues – Storage Management, Charles R. Hurburgh, Roger Elmore

Integrated Crop Management News

It looks like we will have another large wet crop, especially in eastern Iowa. There is less room to accommodate problems from this year because the grain market system is already overloaded with poor quality corn from 2008 crop. However, we learned from 2008 – extra cost in additional handling and drying logistics is likely to pay off in terms of avoiding spoilage losses later on. This would not be a good year to take chances that wetter corn will keep and can be absorbed in the spring/summer.

Stalk And Ear Rots Prevalent In Iowa, Alison E. Robertson Oct 2009

Stalk And Ear Rots Prevalent In Iowa, Alison E. Robertson

Integrated Crop Management News

The cool, wet growing season has favored infection and the development of certain corn ear and stalk rots in Iowa. Foliar diseases that occurred earlier in the growing season may have increased the risk of stalk rots in fields. In corn trials across the state, anthracnose and Gibberella stalk rots are common. Ear rots that are being reported across the state include Diplodia, Gibberella and Fusarium.

Update On Hail Damaged Grain, Charles R. Hurburgh, Alison E. Robertson Sep 2009

Update On Hail Damaged Grain, Charles R. Hurburgh, Alison E. Robertson

Integrated Crop Management News

The situation with the hail damage to crops in north central Iowa is becoming clearer. On Aug. 9, 2009 an intense storm travelled approximately 150 miles from western Sac and Ida counties to eastern Grundy County. The hail swath was about ten miles wide, between Highways I-175 and US-20, with three miles in the middle being almost completely lost. The stones were large, which created major damage to both plants and developing grain. Earlier storms in northeast Iowa also created large losses but the grain itself was less developed.

As of Sept. 27, 2009, we are close to winning the race between early frost and crop maturation across Iowa. The average date of first killing frost ranges from around Oct. 5 in central Iowa; about a week earlier to the north and west ,and a week later in southeast Iowa. It appears now that the 2009 first killing frost will occur at least at the average, and hopefully a bit later.

A near-perfect week! Sept.13 - 20 provided seasonally normal temperatures, bright sunshine and some light rain at week's end; all of which are favorable to Iowa's maturing crop. As of Sept. 21, the mid-range forecast is calling for night temperatures that should NOT approach killing temperatures. If this bears out, it will mean no early frost in 2009.

Manage Soybean Diseases At Harvest Time, Xiao-Bing Yang

Integrated Crop Management News

Two soybean diseases - sudden death syndrome (SDS) and soybean white mold - are wide spread in Iowa this season. In August SDS showed up in almost every Iowa region, with some regions having high disease intensity. Large patches of soybean with SDS symptom are obvious from south to north. White mold, a disease that can drastically cut yields, started to get the attention of producers in late August. This year white mold is so wide spread that agronomists report observing it in many soybean fields in southern Iowa. In northern Iowa, patches of soybean killed by this disease were so abundant ...
