The Environmental Protection Agency has wrapped up its review of the world's most widely used herbicide and plans to release a much-anticipated preliminary risk assessment no later than July.

What should the burndown strategy be for those crops with planting time upon us?

Using herbicides that differ in the ways they kill weeds goes a long way to battling herbicide resistance, according to Iowa State University agronomists.

You may get a whole lot more than you bargained for when you buy a used combine out of state.

The cost of soybean seed has increased more than 225% since the introduction of glyphosate resistant varieties in 1996. This increase in price has caused growers to reduce the rate of seeding in fields. However, the lower crop seeding rate can lead to a more open canopy for weeds and increased competition with the crop.

With row crop harvest underway, it's time to start planning your fall herbicide applications to control winter annual broadleaf weeds and grasses ahead of grain sorghum or corn.

Hopefully, most of our full-season soybean crop has been managed for weeds by this time of the summer and some growers have planted or are still considering double-crop. There is still time to ensure your soybean weed control programs worked by scouting those full-season soybeans for escapes and by selecting effective herbicides to control weeds in double-crop soybeans.

In Water Effects On Pesticide Performance, Montana State pesticide education specialist Reeves Petroff reminds us that pesticides may react with water, especially if the water is considered hard.

The world's most widely used weed killer is not responsible for perpetuating Sudden Death Syndrome (SDS) in soybeans, research shows.

Precision farming technology that will allow reduced herbicide use by accurately identifying and spot-spraying weeds, developed from research funded by the Horticultural Development Company (HDC), is to go into commercial production.
