Weeds compete with crops for sunlight, water, and nutrients, threatening agricultural productivity worldwide. Uncontrolled weeds can quickly dominate fields, reducing crop yields and impacting food supply for a growing global population.

Bayer partners with farmers, weed scientists, retailers, applicators and other agricultural stakeholders to deliver integrated weed management solutions. These programs combine diverse chemical and non-chemical control methods to maximize effectiveness.


Through new herbicide technologies and digital farming tools Bayer provides growers worldwide with cutting-edge weed management services including advanced agronomic practices that address both immediate and long-term agricultural needs.

Herbicides

Sustainable Weed Control Products

Herbicides are essential tools for farmers to control invasive weeds and protect crop yields. Farmers use herbicides before and after planting, considering crop type, season, weather, and weed pressure to select the most effective products and application timing.


Bayer offers a wide range of herbicides tailored to different crops and farming conditions. Our stewardship programs provide agronomic best practices and training to ensure safe and effective herbicide use. Farmers also utilize precision agriculture technologies such as GPS-guided sprayers to apply herbicides accurately, minimizing environmental impact.


Modern synthetic herbicides enable targeted weed control and support sustainable farming practices like no-till and reduced tillage. Icafolin, Bayer's innovative herbicide, represents the first new mode of action for post-emergence weed control in field crops in over 30 years, marking a significant advancement in our Crop Science pipeline. Designed for use in a variety of crops, including soybeans, grains, and fruits, Icafolin provides farmers with a powerful tool to combat increasing herbicide resistance. This new herbicide not only enhances weed management but also supports sustainable agricultural practices by promoting soil health and reducing the need for tillage.


Combining chemical weed control with digital tools and field data allows for precise application, increasing productivity and reducing the need for land expansion. This approach also protects non-target plants and ecosystems.


Environmental safety is a core principle at Bayer. Our products undergo rigorous testing under diverse conditions and international standards to ensure minimal impact on the environment and human health.

Comprehensive Solutions

Integrated Weed Management Programs

Weed Management

Bayer offers sustainable Integrated Weed Management (IWM) programs that guide farmers through science-based best practices for crop protection and herbicide stewardship. These customized solutions demonstrate that a holistic approach—using crop rotation, cover crops, multiple modes of action, and mechanical practices like harvest weed seed control (HWSC)—delivers long-term benefits for farm productivity and soil health.


Combining diverse weed management measures helps maintain effective control systems and supports productive harvests while preserving soil quality.

Farming Techniques

Weed Prevention and Soil Health Improvement with Cover Crops

Cover crops are planted between growing seasons to suppress weeds and enhance soil health. These crops compete with weeds for sunlight and nutrients, reducing weed growth and improving soil structure. Grasses and legumes as cover crops also help optimize fertilizer and crop protection product use.


A consistent cover crop regimen increases soil organic matter, improves soil stability, and boosts moisture and nutrient retention. Organic matter from cover crops enhances water infiltration and reduces evaporation, ensuring crops receive adequate water.
