I am currently planning a replicated on-farm herbicide trial on jalapeño peppers at the farm of Ignacio Estrada Jr in Greenville County. The trial will evaluate the viability of Spartan herbicide as a weed control option. This project is being coordinated with Dr. Mathew Cutulle, a Clemson University specialist based at the Coastal Research and Education Center in Charleston, SC.
I recently completed the Upstate Strawberry Production Meeting at the Spartanburg Community College Cherokee Campus “Institute for Innovation,” a new venue for me. The meeting attracted growers from at least four counties across South Carolina, as well as two farms from North Carolina.
I will also continue my work on thinning peaches using Ethylene. I have experienced difficulty thinning varieties such as Scarlet Prince and July Prince. To address this, I will use a two-pronged approach: thinning during bloom with Ammonium Thiosulfate (ATS), followed by thinning at the fruitlet stage with Ethephon 2 SL. Peach growers currently rely on hand thinning, which is the most expensive labor input in peach production. This makes the development of effective chemical thinning strategies especially important for peach growers in the Upstate of South Carolina.
My final spring training for Upstate vegetable growers will be held on March 12.
