MU Extension guide helps farmers with replant decisions
COLUMBIA, Mo. – Challenging weather has forced Missouri farmers to make difficult decisions on whether to replant crops because of sparse stands or delayed planting.
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…
Test for SCN after soybean harvest
COLUMBIA, Mo. – The best time to test for soybean cyst nematode (SCN) is right after soybean harvest, says University of Missouri Extension plant pathologist Kaitlyn Bissonnette.
Mizzou Weed Science shares Seed Terminator research
COLUMBIA, Mo. – In the 1984 film “The Terminator,” a robotic assassin played by Arnold Schwarzenegger warns, “I’ll be back.” If waterhemp could talk, it might say the same thing. Waterhemp can’t be bargained with. It can’t be reasoned with. The prolific producer of seeds is the state’s No. 1 weed, robbing Missouri agriculture of millions of dollars each year.
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.
Make the most from late-planted soybean
COLUMBIA, Mo. – Soggy fields, low soil temperatures and 16 cloudy days in May delayed soybean planting in Missouri.Average yield for soybean planted in the third week of June is at least 25% less than soybean planted in early May, and July plantings fare even worse, says University of Missouri Extension soybean specialist Bill Wiebold.
Free SCN tests available to farmers
COLUMBIA, Mo. – Missouri farmers can submit two free tests to beat the soybean cyst nematode (SCN) by contacting their county University of Missouri Extension center or the SCN Diagnostics laboratory.
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.
Crops face danger of BMSB damage
COLUMBIA, Mo. – A flurry of calls and emails from homeowners about the brown marmorated stink bug to University of Missouri Extension specialists sounds a warning of what is to come in in the next two years.
SDS appearing in Missouri soybean fields
COLUMBIA, Mo. – University of Missouri Extension agronomists reported during their weekly teleconference that sudden death syndrome (SDS) is showing up in soybean fields across the state.MU Extension plant pathologist Kaitlyn Bissonnette says she is not surprised that the yield-robbing disease has reared its ugly head.
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.
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 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.”
Test fields for SCN and test your SCN IQ
NEVADA, Mo. – Now is the perfect time to test for the No. 1 soybean disease in the U.S. and Canada - soybean cyst nematode (SCN), says University of Missouri Extension field agronomist Pat Miller. It is also a good time to test your IQ on this yield-reducing disease.Soybean cyst nematodes attack soybean roots.SCN began spreading in Missouri in the 1970s and gained a strong foothold in most of the state’s soybean-growing counties by the…

A glut of soybeans?
The combination of the ongoing trade war, large carry-in stocks, fewer hogs in China and the potential shift of corn area to soybeans could result in a large abundance of soybeans, but this is far from certain given the severity of planting delays.
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.
