Scouting for Diseases, VBC

Lesions on the Leaf Late leaf spot is starting to be found in more fields this week, including those with timely and expensive fungicide programs. Switching modes of action and/or including Bravo or sulfur in with the next fungicide application, or tank mixing a systemic product with bravo (e.g., if the previous spray was bravo) […]

Corn, Cotton, and Soybean Disease Update

In the last two weeks, most of us have received large amounts of rainfall. Daily rainfall of over 2 inches was observed in many areas and several places got 5+ inches of rain in those two weeks. In general, the rainfall was good for crops. However, it also increased our odds of getting foliar diseases […]

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 […]

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 […]

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 […]
