ST. JOSEPH, La. – Biological control of aflatoxin contamination in corn is one of the topics that will be discussed during the LSU AgCenter’s Northeast Research Station Field Day June 10.

Aflatoxin, a byproduct of a fungal infection that generally occurs in drought-stressed corn, has become a serious concern for Louisiana corn producers, said Bob Hutchinson, the LSU AgCenter’s regional director for Northeast Louisiana.

The fungus ripped through the state’s corn crop in 1998 and annually threatens large-scale economic harm. Because of its potential economic consequences, a variety of studies have been conducted, and LSU AgCenter scientists will discuss their aflatoxin research during the field day.

Other corn research projects that will be discussed during the field day include those focused on dual-row corn production and corn hybrid performance.

Researchers also will address new chemicals available for weed control with Clearfield rice, as well as weed management with transgenic cotton varieties, control of perennial weeds during the fall in corn and the latest in soybean weed control.

Rounding out the topics are reports on research concerning planting dates and irrigation in cotton, dual-row soybean production, early-season insect and nematode management with precision agricultural practices and planting dates for cotton and soybeans.

The field day begins at 8 a.m., and participants will board trailers to begin field tours of various research sites at the station at 8:15 a.m. The tours and discussions will end at about noon, when lunch will be served to conclude the field day.
