Trichoderma Ear Rot of Corn

Sep 23, 2017 by Steve Crafton
Looking at corn fields the past few weeks I have noticed some ear rots in a few fields. As I seen the scattered dying discolored husk I assumed it was Diplodia Ear Rot.  When I pulled the husk back the ear was covered with the powdery green mold Trichoderma.

Soybean Technology and Herbicide Systems Review

Sep 16, 2017 by Travis Dollarhide
Glyphosate resistant weeds, especially water hemp and palmer amaranth, are a reality for most producers across the soybean growing areas. If not already, there is no question they soon will be. The purpose of this discussion is not to dive too deep into actual herbicide recommendation, as that is a conversation that must happen on a local level to...

NEMASTRIKE™ and Parasitic Nematodes

Sep 10, 2017 by Mark Seem
Nematodes can be responsible for yield loss in agronomic crops. In corn it is estimated that 10% of a crop’s potential yield is lost to nematode damage. 80% of the corn acres in the United States are infested with nematodes. NEMASTRIKE™ is a new technology to combat these microscopic roundworms. The chemistry behind this technology is...

Bacterial Leaf Streak Disease in Corn – Update

Sep 1, 2017 by Matt Teply
Bacterial Leaf Streak Disease (BLS) is caused by the bacteria Xanthomonas vasicola pv. vasculorum.  The disease was officially confirmed to be present in fields in 2016 and symptoms were again observed during the 2017 growing season. Symptoms of the disease were first observed in fields in Southwest Nebraska in 2014.  Confirmed...

Scouting for Soybean Aphids

Aug 24, 2017 by Brian Weihmeir
As we begin to approach the tail end of the growing season, it has been a popular time for growers to be walking fields and evaluate the crops. This time of year tends to be quiet in regards to issues seen in the field. However, one pest that has been noticed recently in soybean fields in parts of the Midwest has been the soybean aphid. Due to the...

Flower and Pod Abortion of Soybeans

Aug 17, 2017 by Greg Peters
It is not uncommon for the soybean plant to abort flowers and small pods as the soybean plant adjusts to the surrounding environment.  The soybean plant does this by forming abscission layer at the base of the flower of pod resulting in the loss of nutrient flow.  Researchers have tried to figure out why these layers form as well as...

Painted Lady Butterfly and Thistle Caterpillar

Aug 15, 2017 by Leonard Luebker
Many of you are now seeing a swarm of butterflies on the road.  See the photo’s?. These are Painted Lady Butterflies.  The larval stage is known as Thistle Caterpillar. This insect overwinters in the southern part of the United States and Mexico.  The butterflies fly into the central and northern corn belt in...

Southern Illinois and NE Missouri Crop Progress

Aug 14, 2017 by Brian Weihmeir
It has been a roller coaster of a year for the southern region. Since the start of planting all the way to today, we have had a tough year. Despite everything that mother nature has thrown at us we are still looking ok. Over the past few weeks, I have had the opportunity to walk fields with growers and get a handle on what to expect come harvest....

Plains West Crop Progress

Aug 14, 2017 by Matt Teply
Southwest Missouri:   Variable is the only word to describe this area of the region.  Wet weather though much of the spring and early summer have caused a few issues.  Early or 1st planted corn that’s on more of the well drained soils looks very good. ...

Northern Illinois Crop Progress

Aug 14, 2017 by Steve Crafton
The corn and soybeans in northern Illinois are moving right along.  Some of the corn in our southern region is starting to dent and soybeans are busy filling pods.  Rains have been spotty in our southern region and that’s how the crops look.  Our northern region I-80 to Wisconsin border is probably the most consistent good...

Western Iowa and Northwest Missouri Crop Progress

Aug 14, 2017 by Greg Peters
The area of western Iowa and Northwest Missouri is a tale of two stories.  According to last week’s drought monitor, Iowa was rated 67 to 70 percent abnormally dry to being in a severe drought.  This effects most of western Iowa with the exception of far southwestern tip which is rated normal.  Most of our area in Missouri is...

Ohio Crop Progress

Aug 14, 2017 by Corey Prosser
As we enter mid August, crops across the state are starting to tell us what harvest will have in store for everyone. The crops have evened out and yields look like they could be great for some, average for others, or in some cases poor due to all the rainfall. It has been a trying year for many and harvest will tell us how everyone has...

Western Region - California

Aug 14, 2017 by Phil Miller
California has seen an abundance of heat.  Growers that are staying up on irrigation are handling the heat stress well.  Some early planted fields have been harvested for silage and a few replanted to corn for a second crop.  Pollination continues for later planted corn.  Irrigation water has been plentiful this year due to the...

Minnesota and Wisconsin Crop Progress

Aug 14, 2017 by Tom Greiner
Crop conditions vary across Minnesota and Wisconsin, depending on the weather patterns during the summer for each state. Minnesota has had very sporadic temperatures with highs in the 90's and a long pattern in late July and early August along with temperatures falling to the low 70's for a high.  Corn in Minnesota is...

Indiana and Mid-South Crop Progress

Aug 14, 2017 by Jesse Grogan
Crop condition has improved in the last month due to timely rains and moderate temperatures. Most late planted corn pollinated in late July and into the first week of August. Soybeans are flowering and setting pods. Early season soybeans have completed flowering. Soybean seed fill is occurring from top to bottom on soybean stems. Irrigation has...

Eastern Iowa Crop Progress

Aug 14, 2017 by Ryan Dunsbergen
One quick look at the drought monitor would give you a good idea of what crops look like in Eastern Iowa.  Currently, almost 30% of Iowa is listed as having no drought conditions and the vast majority of that is in Northeast and East Central Iowa.  These areas have received average to above average rainfall the entire growing...

Plains East Crop Progress

Aug 14, 2017 by Leonard Luebker
The crop outlook has improved considerably the past couple of weeks.  Rain showers have occurred over much of the area.  Rains have been anywhere from .25 to 5 inches each shower.  The rains however, have not been general each time.  One may receive .25 inches of rain, while 2 to 5 miles away, one may receive 1”, or...

Estimating Corn & Soybean Yields Prior to Harvest

Aug 10, 2017 by Mark Seem
CORN: Yields can be estimated pre-harvest by making predictions based on what are considered to be Yield Component Factors. This is popular because it can be used well ahead of harvest; as early as the so-called "roasting ear" or milk (R3) stage of kernel development. Under...

Assessing Corn Pollination

Aug 3, 2017 by Corey Prosser
This year has been a very challenging one to say the least. From a wet spring with a record number of replants, to extreme dry conditions. And for us in Ohio in particular – a very wet year. Some of these issues have impacted corn pollination across the Buckeye state along with others states across the Midwest. Tne of the major factors that...

Rusts are infecting corn fields

Aug 1, 2017 by Mark Seem
Both common rust and Southern rust are being found in corn fields across the Midwest.  Of the two fungi, southern rust is historically the most damaging of the diseases. In fields of late planted (or replanted) commercial field corn, common rust is becoming more noticeable than in years past. The onset of these pathogens and the spread of...
