Just a few “heads ups” this morning on what I am seeing or hearing about in the the fields now.<\/p>\n\n\n\n

The picture above was sent to me by Dr. Jared Whitaker and later he brough samples to Jason Brock in Tifton.\u00a0 Young seedlings wilting and dying soon after emergence with a tell-tale lesion girdling the stem just below the soil line are classic for Rhizoctonia soreshin.\u00a0 While there may be other causes for seedling death, the lesion just below the soil line and, sometimes, barely visible fungal “threads” in association with the lesion are strong indications of Soreshin disease.\u00a0For cotton already planted, there is nothing to be done other than consider replanting if stand loss is severe.\u00a0 (Hopefully it is not as replanting is a last resort.\u00a0<\/p>\n\n\n\n

Corn:\u00a0 Some of our earliest planted corn is approaching the tassel growth stage.\u00a0 Growers are likely to find spots from herbicide drift in the corn like in the picture above.\u00a0 Reassure them that the world is not ending.\u00a0 At least not yet.\u00a0 The growers may also find Northern corn leaf SPOT and COMMON rust in the older, lower leaves.\u00a0 Again, the world is not ending.\u00a0 Yet.\u00a0 But you should also be on the look-out for Northern Corn Leaf Blight (lesions shaped and about the size of a Swisher Sweet).\u00a0 A few lesions scattered throughout the field give us a concern but not necessarily a need for a fungicide.\u00a0 However, a lot of Northern Corn Leaf Blight lesions on a susceptible variety on lower leaves COULD necessitate a fungicide application.<\/p>\n\n\n\n

A few other words for thought:<\/p>\n\n\n\n

It’s going to be cooler and wetter over the next couple of days which could slow germination and growth of young seedlings and affect vigor.\u00a0Should growers consider holding off from planting for a couple days?\u00a0 It wouldn’t hurt from disease and nematode standpoints.\u00a0 Rapid germination and vigorous growth and development help a crop escape some seedling disease.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
