U.S. dicamba ruling won’t touch Canada: Bayer

Thousands of American farmers who have already bought the herbicide now in a bind after court bans over-the-top use

An Arizona court decision that essentially prohibits American farmers from using dicamba for over-the-top spraying on soybeans and cotton will not stop Canadian growers from using the herbicide this year, says Bayer Crop Science Canada.

Crop-killing weeds advance across US farmland as chemicals lose effectiveness

Losing battle with weeds adds pressures to farmers already stressed by inflation, extreme weather

Crop-killing weeds such as kochia are advancing across the U.S. northern plains and Midwest, in the latest sign that weeds are developing resistance to chemicals faster than companies including Bayer BAYGn.DE and Corteva CTVA.N can develop new ones to fight them.

Move makes life difficult for growers who’ve already booked inputs

Reuters – The U.S. Environmental Protection Agency has slightly shortened the window for farmers in major soybean-producing states to use a weedkiller criticized for drifting away from where it is sprayed. The restrictions make it harder for farmers to use dicamba, sold by agrichemical companies like Bayer AG and Syngenta, after some growers have already

Comment: Doubling down won’t solve weed woes

Dicamba was supposed to solve weed problems – instead, it’s making farming harder

Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems. In October 2021 I was a guest on a popular podcast to discuss my recently published book, Seed Money: Monsanto’s Past and Our Food

U.S. EPA reviewing dicamba over crop damage claims

Chicago | Reuters –– The U.S. Environmental Protection Agency is assessing whether dicamba herbicide can be sprayed safely on soybean and cotton plants genetically engineered to resist the chemical, without the procedure posing “unreasonable risks” to other crops, an agency official said Tuesday. Farmers and scientists for years have reported problems with dicamba drifting away
