When Should I spray my soybeans?

Glyphosate can be applied to the crop at any time, but weeds need to be controlled in the first 3 to 4 weeks to maximize soybean plant growth. It is important to spray weeds before they reach 4 inches in height to pre- vent building a resistant weed seed bank.

Are Roundup Ready soybeans available?

Current Roundup Ready crops include soy, maize (corn), canola, sugar beets, cotton, and alfalfa, with wheat still under development. Additional information on Roundup Ready crops is available on the GM Crops List. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties.

You can NOT use 2,4-D products such as 2,4-D LV4 ester, amine, etc. and immediately plant Enlist soybean. Dicamba based products such as Engenia®, Tavium®, or XtendiMax® can be applied pre-plant, pre-emergence, or post-emergence in Roundup Ready 2 Xtend soybean.

Can you apply glyphosate to Roundup Ready soybeans?

However, it is important to remember that there is a maximum soybean growth stage for which glyphosate can be applied to Roundup Ready (glyphosate-resistant) soybeans. Currently, glyphosate labels state that glyphosate can be applied from soybean cracking to “…

When to spray for weeds in soybean fields?

If Roundup Ready canola volunteers are flowering in a soybean crop, yield potential has already been compromised, Lange said. “The horse is out of the barn as they say.” Farmers should scout their soybean fields before and after spraying for weeds, Lange said. It’s important to know what weeds are there and the stages of the weeds and the crop.

When to apply glyphosate to soybeans in Manitoba?

Early weed control is essential to protect Roundup Ready soybean yields, says Dennis Lange, a farm production manager with Manitoba Agriculture, Food and Rural Development (MAFRD) in Altona. Glyphosate can be safely applied when soybeans are in the first trifoliate stage right up to flowering.

What kind of herbicide to use on soybeans?

For those growing conventional soybeans (i.e., non-Roundup Ready or Liberty Link), there are several herbicide options available and many of the herbicides discussed above can be used to control weeds.
