Agronomist Craig Reid says there are effective strategies growers can use to manage herbicide-resistant weeds, such as using longer rotations, cover crops, and tillage.

Managing herbicide-resistant weeds in corn

Planning and variety in rotations is a large factor, but cover crops and herbicide programs help too

Herbicide resistant weeds in all crops are a continuous concern, and for corn, these can be reduced with effective management practices. “The whole strategy [of weed control] is going to […] Read more

Stacking three types of mechanical weed control is nearly as efficient as using herbicides, according to organic crop production researchers.

‘Stacking’ of row-crop tillage shows promise

Three modes of action monitored in organic crop study

Using the same terminology employed by agrochemical manufacturers promoting the “stacking” of herbicide-resistant traits in seed, an organic-sector specialist from the University of Maine sees promise in multiple modes of […] Read more


An analysis of 27 years of herbicide evaluation trials from 1992- 2018 found that when weed control was less than 94 per cent over the entire weed community and growing season, it exacerbated the effect of heat or drought on corn yields.

Weeds may compound effects of climate change impact

Study says corn yields are expected to be reduced as weeds compete for fewer water resources in the American Midwest

Glacier FarmMedia – A U.S. study has found that weeds will likely deepen the negative impact of climate change on corn yields, says a scientist. Such results likely extend to […] Read more



The Weed Zapper has a front applicator bar that disperses electricity to the plants, and is powered by a generator on the back.

Shocking weeds into submission

The Weed Zapper uses electricity to mortally injure weeds

Controlling weeds can be a tough challenge for organic growers with few chemical options, and also for conventional growers battling herbicide-resistant weeds.  For this reason, mechanical weed control has been […] Read more

Start simple with cover crops and choose species based on goals.
