Weed Management: The ultimate guide


Weed control in cereals

Weeds take light, nutrients and water from the crop. They rob yield and affect the profitability of crop production. Effective weed control is a priority from drilling until harvest. In cereals, grass weeds like black grass, Italian rye-grass and brome are the biggest threat but broad leaf weeds cause problems too. Integrated weed management which uses a diverse mix of cultural and chemical control is the best long-term method for weed control. This Guide outlines the most important steps for a successful weed control programme.

Integrated weed management

Integrated Weed Management (IWM) aims for sustainable control and management of weeds using methods designed to complement each other. It involves physical, chemical and biological methods of control without excessive reliance on any one technique. The purpose of IWM is to reduce weed pressure and keep weeds at low levels. The desired outcome is to put weeds off balance making it easier for a herbicide to do its job — which is to protect the yield potential of a crop.

    Managing weeds effectively

    The goals of an IWM plan can be simply stated as follows:

    • Suppress weed growth and biomass accumulation to limit their ability to decrease yield

    • Minimise weed seed production to limit the return of seeds into the soil seed bank

    • Deplete weed seed reserves in the soil to minimise germination in subsequent years

    • Prevent or reduce the spread of weeds to keep problems away from non-problem areas

    Roundup

    Control weeds out of the crop using cultivation and glyphosate to reduce the weed burden germinating in the crop. Learn about how to get the best result by using Roundup formulations which are proven to work in the toughest conditions.
