New insights on the control of dicamba-resistant kochia

Kochia is a highly invasive weed that is common in the Great Plains, where it has developed resistance to multiple herbicides. Now new dicamba-resistant strains are adding to grower worries.

A new approach to keeping crops, people safe

Weeds cause tremendous damage in yield and productivity of crop plants. Losses from weeds account for more than $40 billion in annual revenue for corn and soybean crops alone in North America, according to the Weed Science ...

Study explains waterhemp's metabolic resistance to topramezone

Corn naturally tolerates certain herbicides, detoxifying the chemicals before they can cause harm. It's what allows farmers to spray fields with the class of herbicides known as HPPD-inhibitors, which kill weeds such as waterhemp ...

Herbicide

Herbicides, also commonly known as weedkillers, are pesticides used to kill unwanted plants. Selective herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic "imitations" of plant hormones. Herbicides used to clear waste ground, industrial sites, railways and railway embankments are non-selective and kill all plant material with which they come into contact. Smaller quantities are used in forestry, pasture systems, and management of areas set aside as wildlife habitat.

Some plants produce natural herbicides, such as the genus Juglans (walnuts), or the tree of heaven; such action of natural herbicides, and other related chemical interactions, is called allelopathy.

Herbicides are widely used in agriculture and in landscape turf management. In the U.S., they account for about 70% of all agricultural pesticide use.
