Weed Management: Clearing Fields of Unwanted Plants

[/ce_basic_banner_landing]

A weed is the wrong plant, in the wrong place, at the wrong time. Weeds compete with crops for nutrients in the soil, water in the ground, and access to sunlight. To protect their crops, farmers must spend a great deal of time and effort preventing these invasive plants from taking root and potentially spreading. We are working to continually offer a variety of effective crop protection tools and practices that enable farmers to help the greatest number of plants reach their maximum potential.

Cover Crops

Cover crops, crops planted between growing seasons of a farmer’s primary crop, can help farmers more effectively use fertilizer and crop protection products during the growing season. Grasses and legumes are commonly used cover crops.

Over time, a cover crop regimen increases soil organic matter, leading to improvements in soil structure and stability, and increased moisture and nutrient holding capacity for plant growth. Organic matter left behind from past cover crops can also increase water infiltration and reduces evaporation, keeping water where crops need it.

Herbicides

Herbicides are a pesticide used to manage unwanted plants in a farmer’s field. Farmers can use herbicides before planting to help clear a cover crop or weeds, and after planting when used in conjunction with herbicide-resistant genetically modified (GM) crops. Modern tools like GPS guidance on sprayers and site-specific nozzles help farmers use the right amount, in the right place, at the right time. Monsanto offers several herbicide solutions for farmers including glyphosate and dicamba.

Glyphosate

Glyphosate is the active ingredient in Monsanto’s RoundUp® branded agricultural herbicides, used to control broadleaf weeds and grasses on both farms and front lawns.

Dicamba

Dicamba is the active ingredient in Monsanto’s XtendiMax® herbicide with VaporGrip® technology, used to control broadleaf weeds among corn, soybeans, and cotton that have become glyphosate-resistant, like Palmer amaranth.
