Most of the dryland corn crop tasseled (pollinated) and began reproductive growth during the pop up drought […]
6/24 Corn and Soybean Update
Surviving on tenths of rain is all we are doing right now across SC and the SE USA. High pressure in the North continues to drive moisture to the Gulf and away from the SE at a very water critical time for corn especially. Where irrigation is available, growers need to continue to run pivots […]
6/18 Corn and Soybean Update
As of this week approximately 60% of our corn crop is silking. Tassel/R1 (Silk) is the most water sensitive growth stage of corn, if irrigation is available we need to ensure that we are irrigating corn 2 inches per week minus what is captured through rainfall. In terms of our non-irrigated acreage, yield will suffer […]

However, it very well may have blown spores into our state for several diseases including Southern rust on corn, soybean […]
Peanuts – Patch of Dead Peanuts, CV Pictures
More than one way to skin a cat, more than one reason a patch of peanuts can be dead in a field. Drowned in a bottom, struck by lightning, killed by disease, terminated by herbicide, and other woes… Zinc toxicity can also be fatally toxic. Aside from a soil test report indicating elevated levels, visual […]
Peanuts – Yellow in the Canopy
More rain coming in and out of the week ahead. Hurricane Elsa is estimated to approach near SC in about 5 days, with some bands possibly earlier. Making use of opportunities as we have them to maintain fungicide coverage will help all the more to put our disease management in a more secure position. Playing […]
Corn and Soybean Update – Fungicides, Irrigation, and Tassel Nitrogen
CORN Fungicides As we close in on the 4th of July, we need to consider our possible fungicide applications on corn and soybean. Weather is one of the big drivers for foliar diseases in both of these crops. The worst-case scenario is not a mid-afternoon thunderstorm which delivers 1+ inches of rain but then the […]
Peanuts – Spider Mites
Drake Perrow, crop consultant in Cameron, SC, found spider mites in peanut today. For the obvious, yes this is early, and the more obvious, yes we are dry. Good things going for us now are the relatively cooler temperatures (low-mid 80s) this week, clouds, and the decent chance of rain hopefully we will receive. Especially […]
Update – Foliar Diseases in South Carolina Corn
The majority of our corn crop is at VT or R1 and this is the appropriate time to start making the decision whether or not to spray a fungicide. Observations from South Carolina corn fields: At the Edisto REC Dr. Plumblee and I have walked several fields and the corn is very clean when it […]
Water Requirements for Activating Preemergence Herbicides
With rain visiting our state today, the topic of how much rainfall does it take is timely. Surface applied herbicides, such as Prowl or Valor, typically need a minimum amount water after application to properly “activate” in the upper soil profile. Activation means the herbicide is dissolved in the soil water solution and readily absorbed […]
Peanuts – 45 DAP Fungicides and More
Peanuts planted the last week of April are reaching 45 DAP this week. Fungicide programs for leaf spot should begin no later than 45 DAP and starting closer to 40 or 30 DAP can be warranted in fields with a history of challenging disease pressure, later plantings, volunteers nearby, and similar risk factors. If rains […]
Mid-Season POST Herbicides in Peanut
With most of the state getting an abundance (some places an over-abundance) of rain over the past week, expect weed flushes to begin in earnest. As most plantings are approaching or past the 28-to-30-day mark, there are several options for us once field conditions permit over-the-top spraying. A paraquat program in peanut either tank mixed […]
Stubby Root Nematode in Corn
I am sure that many of you are getting reports of “bad/sad” looking corn in a range of growth stages. As we all know this year’s corn crop has been through every possible type of stress.
