In another win for environmentalists and another big loss for agrochemical company Monsanto, a federal judge in Brazil has suspended the use of products containing glyphosate, the active ingredient in Monsanto’s Roundup herbicide, until the government re-evaluates the toxicology of the chemical. 
Under the temporary ban, the registration of new products containing glyphosate is prohibited, and existing registrations will be suspended for 30 days.
The suspension also applies to the insecticide abamectin and the fungicide thiram. The decision is likely to face multiple appeals. 
Luiz Lourenço, director of agribusiness industry association Abag, remarked:
“I think the judge is wrong and that the decision will be revoked somehow. It is impossible to do agriculture without these products.”
Certain corn and cotton strains that are resistant to glyphosate have been approved in Brazil.
Glyphosate, the most widely used herbicide chemical in the world, has always been controversial, but questions about the safety of the ingredient increased in 2015 after the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) classified glyphosate as a probable human carcinogen. 
More than 4,000 lawsuits have been filed against Monsanto on behalf of people who claim that glyphosate caused them or their loved ones a type of cancer called non-Hodgkin lymphoma. The lawsuits allege that Monsanto suppressed scientific evidence showing that glyphosate could cause cancer.
A 2015 review of 44 papers representing studies in high-income countries found that there was a “striking increase” in the incidence of non-Hodgkin’s type lymphomas in the last 30 years. The authors wrote in the report that farmers have higher rates of cancer overall, likely caused by agrochemical exposure. Glyphosate exposure was found to be positively associated with non-Hodgkin lymphoma.
In June 2018, a U.S. judge in San Francisco ruled that hundreds of lawsuits against Monsanto by cancer survivors or their families could proceed to trial.
