UGA Extension study shows impact of herbicides on pecan trees

By Clint Thompson, University of Georgia

Dicamba and 2,4-D herbicides, sprayed directly on trees at full rates, kill the plant material they touch, but they don’t travel through the tree or linger from year to year, according to a newly released University of Georgia Cooperative Extension pecan study. The study also found that drift from the herbicides does not hurt the trees.

UGA Extension pecan specialist Lenny Wells and UGA Extension weed scientist Eric Prostko researched the effects of low and high concentrations of dicamba and 2,4-D herbicides on pecan trees at the university’s Ponder Farm in Tifton, Georgia. They studied 5-, 8- and 9-year-old ‘Desirable’ pecan trees. No data was collected on older trees. Continue reading

Training is required for dicamba use

In Southeast Farm Press

In October 2017, the Environmental Protection Agency approved revised labeling for new formulations of dicamba products that are marketed as Engenia (BASF), Xtendimax (Monsanto), and FeXapan (DuPont).

These new herbicides were developed in conjunction with the release of dicamba-tolerant soybean (Roundup Ready2 Xtend soybean varieties).  All three products, which were first available for applications during the 2017 growing season, are now classified by the EPA as “RESTRICTED USE” pesticides, meaning that either a commercial or private pesticide certification license must be held by individuals who purchase and apply these products.

USDA research finds conservation tillage works better after first year

In Southeast Farm Press

An onslaught of the weed Palmer amaranth in the southeastern United States has left many farmers wondering if they should continue using environmentally friendly cover crops and conservation tillage or switch to conventional tillage.

Palmer amaranth is aggressive, drought tolerant, a prolific seed producer, and capable of developing resistance to glyphosate, known as Roundup. Because of that, thousands of acres in Alabama and elsewhere are at risk of being converted to conventional tillage, which may better control the weed, but increases soil erosion and threatens long-term soil productivity.  Continue reading

Weed control economical, yield-critical in corn

by Kay Ledbetter, Texas A&M AgriLife

Just how much water are weeds using in a corn crop, and is it more economical to treat or not is the focus of a Texas A&M AgriLife study.

Dr. Jourdan Bell, Texas A&M AgriLife Extension Service agronomist in Amarillo, and her Texas A&M AgriLife Research graduate student Aislinn Walton have found in early results heavy weed pressure could result in a 100-bushels-per acre yield loss on a corn crop. Continue reading
