Potential for delayed orchardgrass seeding during glyphosate-resistant alfalfa establishment
Few herbicides are labeled for weed control when establishing alfalfa (Medicago sativa L.)-grass mixtures. Varying the planting date of the grass in relation to alfalfa and adjusting herbicide application timing could improve weed control and forage grass safety. The research objective was to evaluate the use of glyphosate [N-(phosphonomethyl) glycine] for weed control in seedling ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Volunteer corn presents new challenges for insect resistance management
Genetically-modified (GM) corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] dominate the North American agricultural landscape and are becoming increasingly important as biofuels. However, as herbicide-tolerance and insecticidal traits are often simultaneously expressed by individual plants, glyphosate [N-(phosphonomethyl) glycine]-resistant (GR) volunteer corn is becoming a widespread ...

Why are certain herbicides banned?
Herbicides, also known as weedkillers, are chemical substances used to control and kill unwanted plants (weeds), leaving the desired plants unharmed. While these products are very useful for farmers, they are not always safe. In fact, many herbicides that were in common use around the world a few years ago are slowly being banned. In this blog post, we will look at a few herbicides that are used ...
