Anthracnose leaf blight lesions are tan or brown with dark margins. It is most common where corn follows corn and seldom causes yield loss.
Occurrence of leaf blight and stalk rot is not necessarily related despite being caused by the same pathogen.

Planted @CottonInc nematode trial yesterday @ufifasnfrec. We are testing resistant cultivars, in-furrow nematicide, and seed treatment nematicide for reniform nematode management.
Identical trials are being conducted across the cotton belt against either root-knot or reniform.

Some early stages of Physoderma getting started. Not a simple one to diagnose with just the leaf lesions. Look for the midrib lesions that are the more characteristic brown coloration #mscrops

Boots in the field are vital. Nitrogen losses are difficult to predict, but frequent scouting can reveal needs. Deficiency first appears on lower leaves and the distinctive pattern on corn is unmistakable.
Thus, you can positively ID this issue and respond immediately. 🌽#mscorn

Several calls about poor soybean nodulation this week, mostly on fields new to #soybeans or out of beans for 3–5 years. Inoculants are living organisms—storage, treatment combinations, and time to planting matter. No nodules by V4–V5? Apply 60 lb N now and another 60 lb at R1–R2.

Twas the night before tar spot, when all thru the field
Not a creature was stirring to reduce corn yield
Ears were all growing kernels with care
In hopes the combine soon would be there
The silks were nestled snug in their beds
While visions of pollen grains danced in their heads
