New regulations limit who can make those applications, which raises questions about whether enough certified people will be available to keep herbicides going out on schedule. Some states are pushing now to widely instruct people for the closed-book test they will have to take to be qualified.
 
    
 
"Australia’s farmers went this route only after weeds developed resistance to nearly all herbicides available for their cropping system. The increasing pace of herbicide resistance evolution and the slow introduction of new herbicide sites of action suggest we will face the same dilemma in the not-too-distant future. To prevent further loss of effective herbicides, attitudes towards weed management need to change."

Safeguarding important herbicides means setting up a long-term plan and putting a multi-year strategy in place that includes plenty of moving parts.
 
    
 
The suit challenged legality of XtendiMax registration. Monsanto (now Bayer) and EPA argued that the court should dismiss the lawsuit as moot. The court agreed but also ruled that the plaintiffs should be allowed to fast-track a new lawsuit based on the new 2018 dicamba registration.
 
    
 
“Tilled fields might harbor more weeds because they don’t have the pressure from the ants. If you don’t disturb the soil, you might have more ants.”
 
    

A team of 15 researchers in multiple states has gained insights about how far ahead of planting to pull the trigger. This USDA-funded study is now into its third year and one researcher discusses findings in his own state.

Any licensing hoops applicators have jumped through so far won't count if they expect to apply dicamba in 2019. As ballgames go, this is a brand new one.
 
    

For the first time, glyphosate weed resistance has turned up in the United Kingdom. To make matters worse, this is the first time that glyphosate resistance has been detected in the grass weed sterile brome anywhere in the world.

 
    

The Indiana State Seed Lab conducts hundreds of seed tests on cover crop seed each year, including assays for noxious weed seed. The vast majority of cover crop seed sources are passing these tests at a high rate. There is one glaring exception – cereal rye.

    
 
In addition to the EPA mandated dicamba applicator training, TDA has added 2,4-D Choline formulations (Enlist Duo and Enlist One) for use on 2,4-D tolerant crops to be included in these mandatory trainings.
