How can you kill roundup ready corn in soybeans?

Roundup Ready corn is genetically engineered to be resistant to the herbicide glyphosate, commonly known as Roundup. Soybeans are not naturally resistant to glyphosate, so they can be controlled in Roundup Ready cornfields by applying glyphosate. This will kill the soybeans while leaving the corn unharmed.

There are a few different ways to apply glyphosate to control soybeans in Roundup Ready cornfields. One common method is to apply a pre-emergence application of glyphosate before the soybeans have a chance to germinate. This can be done by spraying the field with glyphosate before planting the corn, or by applying it after planting but before the soybeans emerge.

Another method is to apply a post-emergence application of glyphosate after the soybeans have emerged. This can be done by spraying the field with glyphosate when the soybeans are still small, or by using a hooded sprayer to target the soybeans while avoiding the corn.

The rate of glyphosate that is used to control soybeans in Roundup Ready cornfields will vary depending on the specific product that is being used and the time of application. Always read and follow the label directions carefully when using any herbicide.

In addition to using glyphosate, there are a few other methods that can be used to control soybeans in Roundup Ready cornfields. These include using other herbicides that are effective against soybeans, such as dicamba or glufosinate, or using mechanical control methods, such as cultivation or mowing.

By using the appropriate control methods, it is possible to effectively control soybeans in Roundup Ready cornfields and prevent them from competing with the corn for water, nutrients, and sunlight.
