Defeat your biggest threat - black-grass - before it is too late

Following up with a post-emergent in autumn will press home the advantage on plants weakened by the pre-emergent.

Black-grass plants with enhanced metabolism type resistance (EMR) to Atlantis can still be susceptible at early growth stages.

The aim is to land the herbicide on a small target leaf, so a fine spray quality, low forward speed and low wind speed are essential to maximise deposition and uptake.

Sunny conditions stimulating active growth can contribute to product efficacy, consider spraying on bright dry winter days where both crop and weeds are clearly growing.

Winter kill has a big effect on final levels of control – monitor sick black-grass plants and check if the frost finishes them off.

Harry Strek explains why it is just as important to look at how many weed seeds are being returned to the soil, as well as overall weed biomass, when assessing the success of weed control programmes.

Harry Strek explains why every extra percent control in a weed control programme matters. Just a few percent can be the difference between having a much larger weed problem the following season or having a more manageable population to control.

Harry Strek explains that the more spring crops you have in your rotation the better the chance of being able to control black-grass. 

Harry Strek explains why managing weed patches aggressively in a field will help slow down the evolution of resistance in a field, reduce the chance of more mutations that confer resistance, and to reduce the number of weed seeds that are returned to the soil.
