More farmers adding sulfur to soil
Posted Thursday, February 7, at 11:33 AM In the last few years there has been much discussion about using sulfur fertilizer. More and more producers are using sulfur regularly in their fertility program. Sulfur is critically important in all crops and there are more signs of sulfur deficiency across the country...
Fungicides can help with protection Producers have increased their use of fungicides to optimize yields. Fungicide makers have been increasing the amount and number of fungicide available to help farmers manage disease throughout the growing season. Following is a brief summary of what to expect over the next 24 months...

New herbicide choices for 2013 With all of the weed resistance being noticed in soybeans, herbicide suppliers have produced herbicides for 2013 and future herbicides that feature multiple modes of action, new manufacturing processes and improved formulations of older products. Listed below are some of the products for soybeans...
Bt resistant rootworms starting to show up in surrounding states Most of the corn planted in the United States is Bt corn, and the Cry3Bb1 toxin is the major one deployed in corn against corn rootworm. Bt hybrids used for corn rootworm control are low- to moderate-dose events that leave survivors in every field. When enough heterozygotes survive and mate, a Bt-resistant population can increase rapidly...
Sample for SCN before picking out 2013 seed Soybean cyst nematodes (SCN) are fairly common in this area. A lot of acres are planted to SCN resistant soybeans but not all acres. Sampling for the presence of SCN can provide additional options for selecting soybean varieties for next year. First, if you have not been growing SCN resistant lines, you need to check for the presence of SCN nematodes...
Climate change and its effect on agriculture When the documentary film, An Inconvenient Truth, hit the theater in 2006 it started a discussion about climate change. Today, perception of climate change tends to leave people concerned, dismissive or uninformed. Some farmers are skeptical that climate change is real, others are doubtful it will affect agriculture, and some don't even want to bring it up fearing it might generate another concern about the environmental impact of farming...
New traits available for 2013 seed Now that harvest is winding down for corn, you have some idea of what insect problems you experienced this past growing season. While this is fresh on your mind, it would be a good time to note what problems occurred where. This will aid in selecting your hybrids for 2013...
Mold can spread quickly in grain bins Corn harvest is either winding down or over in most of the local area and some soybean harvest has begun. If you have grain in storage, it is critical to manage it properly. The drought has caused higher levels of mold. Plus warmer weather at harvest means that the temperature inside the bin is higher than normal. ...
Watch out for herbicide carryover Herbicide residual is a good thing in year with adequate rainfall. Weed scientist are now warning that the dry conditions may also increase the risk of herbicide carryover in subsequent crops. The most immediate risks include damage to a fall-seeded crop like wheat, cover crops or a forage grass crop. The drought not only reduced the effectiveness of soil-residual herbicides, but the lack of rainfall also slowed the rate of herbicide degradation...
Spider mites bugging area soybean fields As if the dry weather wasn't enough, spider mites are now having a feast with the soybean crop. At this point in time, spider mites are the insect of greatest concern that can be controlled. Soybeans, in general, look better than the corn in dealing with the dry, hot weather. ...
10 ideas for improving bean yields The various farm publications often offer tips on how to produce higher soybean yields. Depending on which article you see, the number of tips can range from as few as 5 to 20 tips. All of the tips have a lot of commonality and involve common sense decisions...
New herbicides coming for 2012 Fierce is a preemergence herbicide for use in soybeans and reduced-tillage field corn. It has shown residual control of tough weeds, including weeds like glyphosate-, ALS- and triazine resistant Palmer Amaranth, waterhemp, and annual grasses. Valent anticipates EPA registration for 2012...
Getting to 300 per bushels per acre The world population is expected to reach 9 billion people by possibly 2030. In order to feed this population it is predicted that corn will need to average 300 bushel per acre to feed them. Over the last 55 years, the average rate of increase in corn yield has been 1.9 bushels per acre...
Managing volunteer corn may be a problem in 2012 Wind storms late in the growing season of 2011 as well as fields that were flooded resulted in a lot of down corn in the area. The losses associated with the down corn and it's harvesting resulted in concerns over volunteer corn in next season's crop and the possible options to control it...
Palmer amaranth can cause considerable yield reduction Palmer amaranth is a very competitive weed. In some fields with "scattered" pigweed plants, the control was considered good. In a study conducted in soybeans several years ago, one Palmer in 80 feet of soybean row reduced yield 17 percent and one palmer in 60 foot of soybean row reduced yield 27 percent...
Flooded field syndrome could be an issue in 2012 Soils can exhibit a condition called "Flooded Soil Syndrome" after extensive flooding due to the lack of plant growth in submerged areas. This condition exists where crops planted the year after an extended period with no plant growth exhibit reduced early growth and yield. ...
What weeds should you watch for? Good weed control starts by knowing what the predominant weed species problems for each field. Knowing which are the worst weeds will aid in choosing the best product or mix of products to control them. Most major weed and herbicide resistance problems in corn vary by location across the corn belt, within a state, and even within different fields. The following six weeds have been ranked as being the most difficult to control...
Check grain bins for insect infestation Now that harvest is over, you can relax some. However with warmer than normal fall temperatures, developing grain insect populations in on-farm grain storage becomes a possibility. Insect infestations can develop in as little as 3 to 6 weeks following initiation of grain storage. ...
Selecting the right seed It is that time of year when producers start making their selections for next year's corn hybrids and soybean varieties. With all of the corn hybrid and soybean technologies available to growers, an increased number of choices has produced a growing challenge in identifying which traits will provide maximum performance and yield in a grower's specific field. ...
