And they say that this also applies to employing the herbicide glyphosate and the corresponding resistances among wild plants.

Alternative and complementary measures to plant protection agents

“We are reaching a new phase in which the degree of multiple and total resistances is calling into question the sustainability of our present practice,” the researchers conclude. “These risks are particularly conspicuous in resistance to pesticides in transgenic cultivation systems.” The new analysis demonstrated the need to manage susceptibility to pesticides as an ecosystem service. Otherwise, in the long run, plant protection agents would be lost as an option to combat pests, and the threat of an agricultural crisis would arise.

For the future, the researchers recommend supporting an optimally heterogeneous environment, for example by providing refuges free of plant protection agents and by employing different types of plant protection agents. It would be even better to use very different disease and pest control methods.
