Destroying a Poor Stand of Corn and Replanting Back to Corn

Author:  Comments Off on Destroying a Poor Stand of Corn and Replanting Back to Corn

There was very little early corn planted this spring.  The corn that was planted has been subjected to significant cold and wet conditions which increase the probability that some of it may need to be replanted. Hopefully no one will need this information, but if so there are several options to control a thin corn stand and replant back to corn. Continue reading

Late Burndown in Corn

Author:  Comments Off on Late Burndown in Corn

Sprayers are rolling across Tennessee. Most are trying to catch up as we are well behind the burndown pace of many Tennessee springs. Typically by late March we have a good bit of corn ground burned down and often have a few acres planted. The current 10 day forecast calls for a good chance of rain just 2 days out of those 10.  Regardless of whether the forecast is accurate or not, corn burndown and planting will have to occur fairly close together.

Clethodim and Managing Glyphosate-Resistant Grasses

Clethodim is quickly replacing glyphosate as the “go-to” herbicide for grass control in West Tennessee.  It began a few years ago as folks found that ryegrass and poa in many fields could no longer be controlled with glyphosate.  In more recent years the pace has accelerated as the spread of glyphosate-resistant (GR) summer grasses like goosegrass, jungle rice and Johnsongrass have made it necessary to add clethodim to glyphosate to “prop up” the grass control.

Enlist Soybean Gains China Approval: Some Thoughts

Author:  Comments Off on Enlist Soybean Gains China Approval: Some Thoughts

The news this week was the China approval of Enlist E3 soybeans (soybeans tolerant to glufosinate, glyphosate and 2,4-D) for import.  China also approved the import of Syngenta’s MGI soybeans.  Those soybeans are tolerant to Callisto, glufosinate and Balance herbicides. My understanding is this MGI trait in soybeans still needs EU approval so unlike the Enlist E3 soybeans they will not be offered for sale this year. Continue reading
