Some Reminders Before Field Corn Planting (Prostko)<\/a><\/h3>\n\n\n\n

Based upon my 22 years of experience in Georgia, here are 3 things that I know will happen somewhere in a patch of field corn in 2021:<\/p>\n\n\n\n

1) Herbicide carryover will be blamed for corn injury but low soil pH<\/u><\/em><\/strong> is the real problem (Figure 1). Favorable average soil test results and\/or “grid-sampling” do not guarantee that there are no areas of low soil pH in a field.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

2) Herbicide carry-over will be blamed for corn injury but nematodes <\/u><\/em><\/strong>are the real problem (Figure 2).  In my opinion, nematodes are much more of a problem than is currently perceived by many.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

3) Valor (flumioxazin) injury, from either sprayer contamination (i.e. improper cleanout<\/u><\/em><\/strong>) or drift will occur (Figure 3).  Good news is that depending upon rate and stage of growth, field corn has some tolerance to Valor (Figures 4 and 5).<\/p>\n\n\n\n

Enlist™ Soybean Variety Data \u2013 2020 (Prostko)<\/a><\/h3>\n\n\n\n

UGA-OVT just recently released the results of their 2020 soybean yield trials.  In those trials, several Enlist™ (2,4-D choline tolerant) varieties were included.  There has not been much Georgia generated data about the performance of Enlist™ soybean varieties in our state.   A quick summary of those Enlist™ varieties is presented in the following table. <\/p>\n\n\n\n

Five of the eight Enlist™ soybean varieties in these tests had higher yields than the maturity group average.  To get the full report of the preliminary 2020 UGA-OVT soybean yield results, check out this link: https:\/\/swvt.uga.edu\/content\/dam\/caes-subsite\/statewide-variety-testing\/docs\/performance-trials\/2020\/soybean-prelim-2020-tables.pdf<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
