The use of glyphosate in crops has led to the rise of glyphosate-resistant weeds. To combat this, new herbicide-resistant crops are being developed, such as glufosinate and imidazolinone. These crops will help farmers manage weeds more effectively and reduce reliance on glyphosate. Companies are also working on combining different herbicide-resistant genes in crops to make them easier to work with and develop multiple-herbicide-resistant crops.
