University of Missouri Extension State Specialist Kevin Bradley describes how little dicamba and 2,4-D are required to injury sensitive soybean at the 2014 Mizzou Pest Management Field Day.
MU Extension State Specialist Kevin Bradley presents burndown programs for difficult to control marestail, or horseweed, at the 2015 Mizzou Pest Management Field Day.
Mizzou Weed Science graduate student Blake Barlow discusses early-season soybean injury due to preemergent herbicides and how visible injury does not always translate to yield loss at the 2015 Mizzou Pest Management Field Day.
Mizzou Weed Science graduate student Cody Cornelius and MU Extension State Specialist Kevin Bradley discuss the impacts of herbicide carryover on cover crops and how environmental factors play a role at the 2015 Mizzou Pest Management Fi
Mizzou Weed Science graduate student Jaime Farmer discusses the role of waterfowl in transporting weed seed, specifically pigweed seed from one area and introducing it into another area at the 2015 Mizzou Pest Management Field Day.
Herbicide program and application timing are important for control of cover crop species.
At least 16 species of blackberries occur in Missouri. Once established, these plants can be difficult to control given the creeping underground rootstock.
Metsulfuron can be effective on many broadleaf and brush species.
Mizzou Weed Science graduate student Derek Whalen presents his research on the use of cover crops for weed suppression in this 2016 video he filmed for the North Central Weed Science Society of America’s annual meeting.
The uncertainty of spring weather and the increasing challenges of controlling marestail at planting are two reasons that fall herbicide applications can be beneficial.
MU Extension State Specialist Kevin Bradley and Senior Research Specialist Mandy Bish discuss good stewardship of pesticide applications with focus on dicamba and 2,4-D in this 2016 University of Missouri Extension Production.
Herbicide Injury ID aids in the diagnosis of herbicide injury. Search by visible plant symptoms, herbicide trade names, active ingredients, or herbicide site-of-action numbers.

Cattle prefer grass-based diets; however, they will consume other plants when grass is unavailable. This research evaluated effects of herbicide applications when forage ground cover was a mixture of tall fescue and legumes.
Cultural control methods are needed to help control herbicide-resistant pigweeds, such as waterhemp.
Giant ragweed begins germinating in late March and grows 1 to 5 feet taller than the crop, making the species highly competitive.
Mizzou Weed Science graduate student Eric Oseland shares the status of Missouri marestail, or horseweed, populations and herbicide resistances.
Mizzou Weed Science graduate student Eric Oseland describes narrow windrow burning and its possible fit in a weed control system especially when it comes to escaped pigweeds such as waterhemp.
MU Extension State Specialist Kevin Bradley addresses the question of whether treating pastures for weeds is advantageous. Cattle grazing preferences were monitored with GPS-tracking collars.
When corn or soybean are followed by cover crop plantings, the question of herbicide carryover becomes a point of concern.
Mizzou Weed Science graduate student Zach Trower discusses the most common weeds in Missouri pastures and their potential impact on pasture quality in this 2016 video he filmed for the North Central Weed Science Society of America’s annu
MU Extension Specialist Mandy Bish describes surface temperature inversions and why they can be problematic with herbicide applications in this 3-minute video.
Mizzou Weed Science graduate student Brian Dintelmann correlates visual dicamba injury with yield losses in Missouri Soybean fields.
This research summarizes the roles that ducks and geese can play in transporting weed seed, namely waterhemp and Palmer, over long distances.
Waterhemp can reduce soybean yield by 44% if left to compete over the season. Control in soybean is challenging because the species rapidly adapts to herbicides and develops resistance.
