Rain, heat increase risk of ponding
COLUMBIA, Mo. – Predicted temperatures in the low 90s the week of May 8 combined with intense or recurrent rainfall could result in damage to corn and soybean crops from ponding, saturated soils and flooding, says University of Missouri Extension agronomist Bill Wiebold.Survival of submerged corn and soybean seedlings depends on seed quality, flood duration, water temperatures, how fast fields dry and location of the growing point in…
New MU guide looks at silage breakeven price
COLUMBIA, Mo. – University of Missouri Extension recently released an updated cost analyzer to help farmers estimate the breakeven price to justify harvesting corn as silage rather than grain.“Frequently, corn harvested for silage was planted for harvest as a grain crop,” says Joe Horner, an MU Extension agricultural business and policy specialist. Reasons for this change can include feed needs as well as drought and other events that…
Mother Nature's drenchings damage crops
COLUMBIA, Mo. – Mother Nature has not been kind to Missouri agriculture in 2021, says University of Missouri Extension soybean specialist Bill Wiebold.Spring rains delayed corn and soybean planting well beyond the best date for yield, says Wiebold. Then the rain stopped and hot, dry weather slowed growth. Frequent heavy rains added to the misery in Missouri fields.
Spring rains bring root rots to Missouri field crops
COLUMBIA, Mo. – Frequent spring rains in Missouri set the stage for seedling and root rotting diseases that can lower yields.Pythium species usually infect the roots of corn, soybean and wheat, especially in the northern half of the state, says University of Missouri Extension plant pathologist Kaitlyn Bissonnette.
Should soybean be planted before corn? MU research still favors corn
COLUMBIA, Mo. – In recent years, the agriculture community began discussing whether it makes sense to plant soybean first and delay corn planting.The University of Missouri Food and Agricultural Policy Research Institute predicts a 7% increase in soybean acres planted in 2021. That leaves farmers wondering whether they could, or should, plant soybean before corn.
Treat spider mites now
COLUMBIA, Mo. – Scout now for spider mites, says University of Missouri Extension field crops entomologist Kevin Rice. Dry weather throughout the state creates ideal conditions for spider mite outbreaks.MU Extension agronomists reported mites in fields across the state during their weekly teleconference on Aug. 26. Mite populations can double about every five to seven days under drought conditions.
Corn ears tell us what went right, what went wrong
COLUMBIA, Mo. – It sounds corny, but if we use our ears, corn ears will tell us why yields are down, says University of Missouri Extension state agronomist Bill Wiebold. Corn ears tell and show us what went wrong during pollination and fertilization, the most critical time of yield establishment. The ear takes us on amazing journey of its hard work to make kernels for high yields and profits.
Scout for two emerging corn diseases in Midwest
COLUMBIA, Mo. – Missouri corn growers should scout for two emerging corn diseases: bacterial leaf streak (BLS) and tar spot, says University of Missouri Extension plant pathologist Kaitlyn Bissonnette. These diseases appeared for the first time in Missouri in 2019. They have caused severe economic losses in surrounding states. Bissonnette offers facts and tips for growers to monitor their spread. Bacterial leaf streak
Too little water, too much heat puts tasseling corn at risk
COLUMBIA, Mo. – Moderate drought for as little as five consecutive days can cause major damage in corn, according to University of Missouri Extension agronomist Bill Wiebold.
Wet, cool wet weather playing havoc with crops
COLUMBIA, Mo. – Some Missouri corn producers are seeing damage from cold, wet soil conditions and hail.Corn growers participating in the University of Missouri Extension Plant Sciences weekly online town hall meeting on May 8 reported seeing seedling leaves of corn twist and unfurl underground.
MU research: Corn emerging in 1-week window has little impact on yield
COLUMBIA, Mo. – Research by University of Missouri Extension agronomists shows that there is little yield difference in unevenly emerged corn. MU Extension agronomist Bill Wiebold researched corn emergence’s effect on yield in 2010 and 2011. Wiebold tagged individual plants from emergence through harvest. He compared the weight and height of early-emerging, mid-emerging and late-emerging plants.
With freezing temperatures predicted, put the brakes on corn planting
COLUMBIA, Mo. – University of Missouri Extension agronomists caution that farmers should delay corn planting in light of predicted freezing temperatures.MU Extension grain crops specialist Greg Luce said on April 9 that “the very cold and very long cold spell in the week ahead could put newly planted corn seed at high risk of damage.”
MU Soil and Plant Testing Lab still open and serving Missouri agriculture
COLUMBIA, Mo. – For now, the University of Missouri Soil and Plant Testing Laboratory remains open.“We understand the essential role the lab plays in supporting Missouri's agricultural industry,” said Robert Kallenbach, MU Extension senior program director for agriculture and environment. “If we can continue to operate safely, the MU Soil Testing Laboratory in Columbia will continue to accept samples.”

Corn prices headed up?
The outlook for corn prices is more positive because corn is likely to experience a significant downward supply shock. Not only will planted area be reduced, but the yields will also likely be significantly lower.
Missouri planting progress data as of June 23, 2019
The rain returned to Missouri this past week, leaving only 2.1 days suitable for fieldwork. Soybean plantings progressed by 9 percentage points, but progress was minimal in corn, rice and cotton.
