  • Some plants are more sensitive to herbicides during reproductive stages of life cycle

    This study assessed the effects of herbicides on non-target plants in Denmark and Canada. The findings showed that some plants are more sensitive to herbicides in the reproductive stages of their life cycle and can experience delays in flowering and reduced seed production. The authors say future ecological assessments should consider reproductive outcomes. Herbicides are some of the most widely ...
