Soybeans don’t go in the ground for three months. Then it’s another couple of months before you would spray fungicides. However, it’s not too early to weigh your options.
Keep your Bible on the nightstand and a copy of Purdue University’s Corn & Soybean Field Guide in the glove compartment. You’ll refresh your spirit, and insect and disease pests will get what’s coming to them, too.
Stinkbugs leave a powerful impression. As I began writing this story, I started smelling one that I searched for — in vain. Hopefully, you’ll also search for it in vain in your orchards and fields during the fast-coming growing season.
Suppose your budget said “no” to planting all triple-stack hybrids. They include the Bt trait for rootworm control. If you still opted for some Bt rootworm corn, where should you plant it?
You’re scouting an irrigated cornfield the first week of July. Gray leaf spot is off to a healthy start. Then you check the disease rating chart for that hybrid and see that it rates 6 of 9 for gray leaf spot, with 1 being most tolerant and 9 being susceptible.
How do you control rootworms on refuge acres in Bt rootworm corn fields? Or how do you stop the pests if you’re growing non-GMO corn for specialty markets?
Should you plan on corn fungicide treatments in 2010? The answer isn’t as simple as “How much does it cost?”
Recent University of Georgia crop enterprise estimates suggest field corn has the potential to be one of the most profitable crops grown in this region in 2010. When I wrote this article in January, March to December corn contracts were selling between $4.21 to $4.48 per bushel. I hope it stays that way. Having corn in a rotation where atrazine and other modes of action can be used is a great way to combat glyphosate and ALS resistance!
The last six months produced a great amount of moisture in Texas cotton country. That holds potential for the 2010 cotton crop to have a strong start. But with the prolific growth of weeds serving as perfect hosts for bugs, it may also be a challenging season.
After harvest and planting, June is our third busiest time in the fields, except when we’re still planting in June. Scouting fields, spraying pesticides and sidedressing fertilizer consume the majority of our time.
You look at current commodity prices and recheck your crop budget. It’s possible you may need to trim costs. If you still want to make sure your soybeans are protected as much as possible, where do you put those limited dollars you can spend on fungicides?
Texas crop farmers are advised to give serious consideration to rotating herbicides as the potential for resistance to certain compounds becomes more common, according to a Texas AgriLife Extension Service specialist.
Most farmers cringe at the thought of insects in their cornfields. Mark Lawson, Danville, invites them. In fact, sometimes he inoculates plots to make sure insects are present. Then he traps, keeps records and notices how well hybrids with insect-resistant traits handle the pests.
Insects from the South are creeping northward. At least three insect pests that have been common in Southern soybean fields for years are finding their way more and more into Nebraska fields.
A scoop — or shovel, if you prefer to call it that — was about as effective as any weapon Mid-Atlantic farmers tried last year against swarms of brown marmorated stinkbugs, or BSMB. Formerly just a stinking nuisance, the bug exploded into a major crop-insect problem last summer.
Soft wheat growers have gradually inched planting dates ahead of long-established Hessian-fly-free dates. Giving fly-resistant varieties a few extra days of warm growing weather helps the cover crop soak up more nitrogen and reduce erosion losses.
In more ways than one, Arkansas has become the Wild West of weed pressure. The weeds are out of control. Farmers are desperate. Some folks are facing full-blown glyphosate-resistant populations of giant ragweed, common ragweed, johnsongrass, marestail and waterhemp.
At 700 per plant, the economic threshold for soybean aphids is fairly high.
Beetles are chomping their way through salt cedar at Lake Meredith in Texas.
The simple, straightforward name says it all — Tobacco Day. This annual event was held at the Johnston County Extension Center near Smithfield, N.C., on Dec. 1, and a hall full of tobacco growers and industry associates had the opportunity to “collect their collective thoughts,” so to speak, on the state of the industry.
If North Carolina State University entomologist Dominic Resig were giving out awards, the trophy for the insect with the most impact on soybean producers last year would have to go to the kudzu bug.
An amazing thing is happening at Georgia’s peanut production meetings in 2013. During every presentation, University of Georgia Extension agronomist John Beasley is urging growers to plant a portion of their crop in the latter part of April to achieve top yields.
Quick! Take this quiz before you look at the chart. First, were perennial weeds more common today or in the 1940s? Second, which weeds have always given Midwesterners more fits, grasses or broadleaves? Finally, how many perennial weeds were among the recent top five common weeds?
Wireworms are long, slender, brown, shiny insects aptly named since they look downright “wiry.” They’re more of a concern at earlier planting dates, notes Dan Ritter, Newton County Extension ag educator. Ritter is also a Certified Crop Adviser.
Soybean diseases that max out in a cool, wet year thrived in 2009. Even farmers with 30-inch soybean rows battled white mold, and that’s not supposed to happen. However, the disease challenges you face in soybeans in 2010 could be different.
Sprayers and equipment for sprayers are a major draw at the National Farm Machinery Show in Louisville, Ky. One reader says he’s going there to buy sprayer tips. He would like to buy one set of tips. He’ll spray Bicep early, then either glyphosate or glufos-inate on herbicide-tolerant hybrids.
Anyone who has sprayed 2,4-D knows it can drift and injure soybeans. Within two to three years, Dow AgroSciences hopes to introduce 2,4-D-tolerant corn, meaning 2,4-D may become popular again.
There are many acronyms in agriculture. Some of the more popular ones include FSA, for Farm Service Agency; ISDA, for Indiana State Department of Agriculture; and USDA. Another acronym in agriculture today is CCA, which stands for Certified Crop Adviser.
Maybe the mercury is at zero and there’s 6 inches of snow outside as you read this. Maybe not. Either way, odds are your target date for corn planting is less than three months away. The Indiana Certified Crop Advisers crops panel continues the age-old debate about which hybrids to plant first.
Last season, several new and unusual insects showed up in Nebraska soybeans, with others expected in the near future moving in mostly from the South and East. Damage from these new insects is sporadic. While some of these bugs may rise again in 2012, nothing is certain. Here is a primer on new pests to watch for.
