Dicamba Research Issues Starting to Surface

After many weeks in the denial and back steppping mode by the manufacturers of the new formulations of dicamba, we seem to be getting some information that perhaps Monsanto, BASF and DuPont need to take another look at what they did wrong.  First it looks like they hid behind the veil of corporate secrecy to get their label approvals. It also looks like there was little field testing of the products.  It looked good on paper so lets run with it.  Check out the RPM Soils Facebook Page for links with all the details.  We have been posting there.

Subsoil Moisture

We did a septic tank evaluation today about 5 miles west of Fillmore.  Soil is very dry to a depth of 4 feet.  This was in a corn field, so realistic of field conditions.  from 4 to five feet there is a little moisture.  Corn looked very good under the circumstances.

Southern Corn Rust

As if we have not had enough challenges this year what with too wet, too dry, and herbicide issues in abundance, Southern corn rust has moved north much faster than any other year.   Of course if your crops are already burned up as the corn below near Tower Hill,  no treatment may be the best option.  If you have gotten the timely rains, scout and follow treatment options.  Purdue has a good writeup.

Comments on Weather and Crop Report

This week's weather and crop report is interesting.  It shows corn condition slightly better than soybeans.  63% of corn is good to excellent.  59% of corn is good to excellent.  My northern Illinois observer tells me that fields are still very wet.  Southwest and West Southwest regions are both showing lots of inadequate moisture reports.  Moisture is hard to get a real good handle on because showers are very scattered in the dry areas.   It is interesting to note that the dry areas are also the hot areas.  That is a bad combination.  I have seen a lot that is getting worse by the day.  Even some soybeans are beyond help. those areas.  Rain will help on better soils, but there is no rain in the forecast until Friday.

Dying Crops

Not everything looks as below, but crops look worse every time I go to St. Charles Co Mo.  Lots of land to the south if feeling dry weather effects.  Rain next week won't revive dead plants.

Subsoil Moisture

We had septic tank investigations in eastern Fayette County today.  As I drove over there, it was evident that rain had fallen the whole way.  First stop was at St. Elmo.  Judging from about 3 inches of moist topsoil my guess would be they had a half inch of rain or less.  The first 30 inches were fairly dry.  Soil below that was most.  Near Vandalia, soil was dry below the recent rainfall moisture to about 2 feet.  Moisture at those depths is considered available, but it takes more energy for the plants to pump it.  With corn pollinating and soybeans flowering, soil moisture is tenuous at best.  As temperatures rise, uptake can't keep up with evapo-transpiration.

Dry Areas

Last week was pretty good for most of Illinois from a rainfall standpoint, but there were gaps in the West South Central area especially.  Some areas got very little rainfall.  Crops are starting to show a good bit of stress.  The photo below was on some sandy soils in St. Charles County, Mo.  The areas of burned up corn will continue to get larger every day now.
