Corn production is forecast at 13.8 billion bushels, up 28% from 2012. If realized, this will be a new record production for the United States. Soybean production is forecast at 3.26 billion bushels, up 8% from last year. If realized, production will be the third largest on record....More
Recently, populations of Palmer amaranth have been identified in several Illinois counties. The density of many populations is relatively low, and often these plants occur only in small patches. However, a few scattered plants this year can lead to severe infestations within only a few years....More
It’s time to get into fields to see how successful pollination has been. Once silks start to dry, remove husks and shake or pull on silks. Those that detach easily are from fertilized kernels, while those that stay attached are on kernels that have not been fertilized....More
Jeff Housman, district agronomist, Mycogen, advises farmers to get out and walk corn fields to scout for corn rootworm damage. He says to start digging roots and evaluate them for corn rootworm pressure. "Management strategies are key," says Housman....More
Higher soybean prices make yield-enhancing crop inputs during the growing season more attractive. One potential input on many growers’ minds is foliar fungicides to help manage several common foliar diseases if the need arises. DuPont Pioneer researchers provide tips to help you determine if a foliar fungicide is warranted this season....More
Crop conditions across the Midwest are quite variable in late July, depending on planting date, as well as impacts from heavy rainfalls in June and the recent dry weather conditions in late July. Overall, across the southwestern and the western portions of south-central Minnesota, a large percentage of corn and soybeans are in fair to good condition; however, excessive rainfall, along with very dry weather recently, in some locations could reduce 2013 yield potential. Crop conditions in the balance of southern Minnesota and adjoining areas of northern Iowa are much less favorable, due to the significant amount of late and prevented planting in 2013....More
Nearly three-quarters of the overall corn crop has started silking, and 8% of the overall crop has reached dough stage. Over half of the overall soybean crop is blooming, at 65%, 9 points behind the five-year average. Twenty percent of the overall crop is setting pods....More
Some cornfields in Iowa are now silking, and even though we had a longer planting period than usual, most will be well into reproductive stages shortly. Tristan Mueller, ISA On-Farm Network program manager, says now’s the time to be watching your fields for adult corn rootworm beetles....More
Corn & Soybean Digest editor Kurt Lawton went on a root dig this week on a northeast Iowa farm. He explored a Mycogen rootworm test plot with district agronomist Jeff Housman. Check out these scouting tips for corn rootworm damage on roots as well as silks. Housman estimated a 40-50-bu. loss in this test plot based on early indications of rootworm severity.
It's time to start scouting corn fields for corn earworm and western bean cutworm. Here are management tips, from insecticide use to best management practices to keep these corn insects in check this season....More
There were many who expected December 2013 corn futures prices to already be below $4.50. That was before continued wet weather slowed planting and crop progression. The contract closed Friday at $5. That’s close to $2 below what the old-crop July contract expired at last week. Tight supplies kept old-crop higher....More
The water has hopefully found its way off of the fields. Flooding for greater than two days may reduce soybean yield by as much 20% compared to one-day flooding events on soils with higher clay content. For soybean fields with less flooding, we have several issues that are brewing, like soybean diseases to be scouted for.
Farmers who spray fungicide on corn “just as a precaution,” don’t have to worry this year about Extension specialists applying a guilt trip to them. Plant pathologists from several Corn Belt universities are suggesting fungicide applications on corn and others are recommending it. But farmers who apply a fungicide are doing it because there is more of a threat this year, than just doing it because it might boost the yield....More
Purdue University researchers have identified two genes within the soybean genome that are highly resistant to a soilborne pathogen that causes Phytophthora root and stem rot, a disease that costs U.S. soybean growers more than $250 million annually in lost yield. The discovery, made by a team of scientists led by Jianxin Ma and Teresa Hughes, could lead to the development of soybean cultivars better able to withstand the pathogen Phytophthora sojae. The Purdue research was published online by Theoretical and Applied Genetics and is to appear in the journal's November print edition....More
Persistent rains during the past two weeks have resulted in ponding and saturated soils in many corn fields and led to questions concerning what impact these conditions will have on corn performance. The extent to which ponding injures corn is determined by several factors including: plant stage of development when ponding occurs, duration of ponding and air/soil temperatures....More
As is well known, corn and soybean production is concentrated in the Corn Belt, with significant amounts of production occurring in the Upper Midwest, parts of the Great Plains and down the Mississippi River....More
