What does dicamba kill?
Dicamba is an herbicide that controls a wide range of weeds. It works by causing the weed to stop growing while leaving the crop unharmed. Unfortunately, there have been reports of crops being damaged by dicamba. This is because dicamba does not target just weed seeds but also the plants’ roots.
What are some different examples of herbicides?
Examples of contact herbicides are diclofop, dinoseb, diquat, and paraquat. Certain contact herbicides, like diquat and paraquat, are deactivated by soil particles.They must be mixed with clear water and applied directly to the vegetation.

How does dicamba affect the environment?
Dicamba is released directly to the environment by its application as an herbicide for the control of annual broadleaf weeds. It may cause damage to plants as a result of its absorption from the soil by plant roots. Dicamba is mobile in most soils and significant leaching is possible. The adsorption of dicamba to organo-clay soil is influenced by soil pH with the greatest adsorption to soil occurring in acidic soils. Dicamba is moderately persistent in soil. Its reported half-life in soil ranges from 1 to 6 weeks. Dicamba is likely to be more rapidly degraded in soils with high microbial populations, but dissipates more slowly in hardwood forests and wetlands than would be expected from the results of laboratory studies.
What is the chemical that converts dicamba to?
Genetically modified crops. The soil bacterium Pseudomonas maltophilia (strain DI-6) converts dicamba to 3,6-dichlorosalicylic acid (3,6-DCSA), which is adsorbed to soil much more strongly than is dicamba, but lacks herbicidal activity. Little information is available on the toxicity of this breakdown intermediate.
Why was dicamba banned in Arkansas?
Arkansas and Missouri banned the sale and use of dicamba in July 2017 in response to complaints of crop damage due to drift. Monsanto responded by arguing that not all instances of crop damage had been investigated and a ban was premature.

Complaints against dicamba accelerated after the EPA approved a Monsanto-created soybean which could tolerate it in 2016. The soybean was a part of Monsanto's Xtend products.
Why is dicamba so controversial?
Dicamba came under scrutiny due to its tendency to vaporize from treated fields and spread to neighboring crops. Monsanto began offering crops resistant to dicamba before a reformulated and drift resistant herbicide, which they claimed would be less likely to affect neighboring fields, had gained approval from the Environmental Protection Agency. Incidents in which dicamba affected neighboring fields led to complaints from farmers and fines in some US states. A lower volatility formulation, M1768, was approved by the EPA in November 2016. However, this formulation has not been evaluated by experts outside of Monsanto.

If you get pure dicamba on your skin, it is low in toxicity, however skin irritation may develop. If you get dicamba in your eyes, it is moderately toxic. If dicamba is swallowed, people have reported symptoms such as vomiting, loss of appetite and muscle spasms. If a large amount is swallowed, diarrhea and abdominal pain have been reported.
What happens to dicamba when it enters the body?

What is dicamba herbicide?
Dicamba is a selective herbicide in the chlorophenoxy family of chemicals that controls or suppresses only broadleaf plants, but will leave grass weeds and plants alone. This is unlike glyphosate that is nonselective and controls plants regardless of the species. Dicamba also has some residual properties that persist in the soil, while glyphosate is a non-residual. While dicamba has been introduced as a vehicle to combat glyphosate-resistant weeds, Knezevic says there are currently 16 weeds in the U.S. resistant to glyphosate, but there are also seven weeds already showing resistance to dicamba, including kochia.

Overview
Use as an herbicide
Dicamba kills annual and perennial broadleaf weeds. Its primary commercial applications are weed control for grain crops and turf areas. It is also used to control brush and bracken in pastures, as well as controlling legumes and cacti. In combination with a phenoxy herbicide or with other herbicides, dicamba can be used for weed control in range land and other noncrop areas (fence rows, roadways, and wastage). Dicamba is toxic to conifer species but is in general less to…
Resistance
Some farmers and researchers have expressed concern about herbicide resistance after the introduction of resistant crops. In the laboratory, researchers have demonstrated weed resistance to dicamba within three generations of exposure. Similar herbicide resistant weeds arose after the introduction of glyphosate-resistant crops (marketed as 'Roundup Ready'). Some weed species, like Amaranthus palmeri, have developed resistance to dicamba. Dicamba resistance in Bassia …
