Summary
Effective herbicide-resistant weed management (HRWM) requires prioritizing practices that reduce herbicide selection pressure. Crop diversity is the most impactful HRWM practice, forming the foundation for other essential strategies.
Area of Science:
- Agricultural Science
- Agronomy
- Weed Science
Background:
- Herbicide-resistant weed management (HRWM) is crucial for sustainable agriculture.
- Global recommendations exist, but regional prioritization is needed, especially in North America's northern Great Plains.
- Understanding grower experiences is key to identifying impactful HRWM practices.
Purpose of the Study:
- To identify and prioritize herbicide-resistant weed management (HRWM) practices.
- To mitigate or manage herbicide selection pressure in the northern Great Plains.
- To provide a foundation for effective weed management strategies.
Main Methods:
- Collaborative research and extension activities over 30 years.
- Dialogue and engagement with growers in cereal, oilseed, and pulse crop production.
- Expert perspective based on extensive farming experience.
Main Results:
- A ranked list of the top 10 herbicide-resistant weed management (HRWM) practices was developed.
- Crop diversity was identified as the foundational and most impactful HRWM practice.
- Practices have broad applicability but may require regional ranking adjustments.
Conclusions:
- Crop diversity is the cornerstone of effective herbicide-resistant weed management (HRWM).
- Prioritizing HRWM practices is essential for managing herbicide selection pressure.
- A strategic approach to HRWM, led by crop diversity, supports sustainable agriculture.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
