MU Field Scouting Report: No freeze damage to wheat, delayed corn planting

Parsons, Kansas — Jill Scheidt, agronomy specialist with University of Missouri Extension in Barton County, scouted fields in Barton County on May 8.

According to Scheidt, wheat is in the flag leaf to early boot stage. No freeze damage to the wheat head was seen. Temporary phosphorus deficiency, identified by purpling on leaf tips, was seen due to cold weather.

“Lodging is a concern now. If the wheat is unable to stand most of the way back up, it could result in up to a 50 percent yield loss if wheat is in the boot stage,” said Scheidt. “If the stem has been broken below the growing point due to the weight of the snow, those plants will be a total loss if they are in the flag leaf or boot stage. Less mature wheat is more likely to recover.”

Scheidt warns anyone thinking about switching from corn to soybeans, that costs and benefits of switching may not prove wise until planting is delayed until the end of May.

“If corn is planted, do not switch to a shorter maturity date variety. Maturity levels will move faster with increasing temperatures. Switching to an earlier maturing variety may result in corn pollinating too soon,” said Scheidt.

Delayed planting of corn causes concern for black cutworm, which clip the corn plants off below or above soil level. If the corn plant is cut off at soil level, the growing point may have been damaged and corn may not be able to recover.

If 2-3 percent of plants are damaged at or below soil level, or if 6-8 percent of plants are damaged above soil level, an insecticide is justified. A medium rate of Mustang Max or Warrior II is recommended.

“Cold weather should not damage corn because the growing point is still protected; when corn reaches 12” then a concern for frost damage may be possible,” said Scheidt.

The weekly field scouting report is sponsored by University of Missouri Extension and Barton County Extension. For more information on this scouting report, or to learn how you can receive it a week earlier by telephone, contact the MU Extension Center in Barton County at 417-682-3579. £

  • wheat_freeze_lodging.jpg Freeze could damage some Kan. wheat

    The hard freeze throughout Kansas in the early morning hours of April 15, could cause some damage to wheat, said Jim Shroyer, K-State Research and Extension crop production specialist. Wheat in the jointing stage is most at risk, he said.

    USDA’s April 9 World Agricultural Supply and Demand Estimates continued a series of recent reports that have offered corn and soybean producers a more optimistic grain-price outlook than what was expected for most of the winter, Purdue Extension agricultural economist Chris Hurt says.

  • USDA: Corn acres expected to drop 4%

    The amount of American cropland devoted to corn is expected to shrink about 4 percent this year as farmers devote more acres to soybeans, the U.S. Department of Agriculture said last week.

  • MU economist: Corn, bean price volatility next 5 years

    Expect volatility in the soybean and corn markets over the next five years, said Pat Westhoff, director of the University of Missouri Food and Agricultural Policy Research Institute (MU FAPRI).
    Look for corn prices to drop to $4 per bushel and soybean to $10 per bushel on average for the next five years, he said.

  • marestail.jpg Plan now to control marestail in soybeans

    Controlling marestail in soybeans has been a big challenge for Kansas no-till producers in recent years.
    Because soybeans are generally planted later in the season, and marestail generally germinates in the fall or early spring, application timing and weed size are critical factors to successful control.

  • Checking alfalfa for winter injury

    In the last couple of weeks, I’ve heard many concerns about alfalfa production for this spring.
    Cold temperatures and lack of snow cover are the two main issues producers are worried about for next season’s crop production, as certainly the alfalfa plant could die if exposed to extremely cold temperatures. In general, alfalfa plants can tolerate up to three weeks of winter injury before the plants are killed.

  • soypods.jpg USDA reports on status of GE crops

    Genetically engineered (GE) varieties with pest management traits became commercially available for major crops in 1996.
    More than 15 years later, adoption of these varieties by U.S. farmers is widespread and U.S. consumers eat many products derived from GE crops — including corn-meal, oils, and sugars — largely unaware that these products were derived from GE crops.
