“Superweeds” Immune to Glyphosate Prove Less Susceptible to Diseases

According to the Purdue University research, scientists trying to understand the way superweeds get their immunity against the common herbicide glyphosate may have lacked the essential piece of information.
Everybody knows that glyphosate, the active ingredient included in the popular herbicide called the “RoundUp” kills the majority of weeds across the USA. Not all of them, however. That made the farmers take some additional steps as far as the herbicides go. It is not quite clear what mechanisms have let weeds become resistant to the weed killers, yet some scientists believe that soil microbes might be responsible for that process.
It could be true as most laboratory tests are done in sterile soil, lacking all the microbes. These findings, published in Weed Science journal may bring all the details of the process owing to which some plants are not affected by the glyphosate. And that’s good news for  the agriculture industry as some further research is going to check how fungi in the soil affect root development, both with and without glyphosate. Now, farmers are hoping that the findings of the scientists from Purdue University will allow them to finally grow some fine crops, free of weeds and fungi.
