Update-Public Release of Pesticide Incident Data
In July 2023, the EPA posted 10 years (2013-2022) of pesticide incident (see glossary) data on its website. This was done to increase transparency and provide a better understanding of pesticide exposures, including exposures to vulnerable populations.

Mid-Season Disease Management
At 3 to 4 weeks after bloom, the risks of black rot (BR), Phomopsis (Ph; including cane and leaf spot, and fruit rot), and powdery mildew (PM) are decreasing. Downy mildew (DM) will be the main threat. While most Botrytis bunch rot infections occur around bloom and fruit set, bunch closing and veraison may also be critical points for protection when weather conditions are favorable for infection, especially on susceptible varieties.
Updated: May 24, 2023
Pre-Bloom To Post-Bloom Disease Management
The growth period from 2 weeks pre-bloom until 3 to 4 weeks post-bloom is the most critical for protecting foliage, and especially flowers and newly set fruit from black rot (BR), Phomopsis (Ph), powdery mildew (PM), Downy mildew (DM), and Botrytis bunch rot infections.

Bt and Herbicide Tolerant Traits in Corn and Current Resistance of Target Insect Pests
Listed below are the corn trait packages to make it easier to understand seed guides, sales material and bag tags. It is an abbreviated version of the Bt trait table plus related extension materials free online at: https://www.texasinsects.org/bt-corn-trait-table.html. Information listed Includes the name of each trait package, bag tag code, Bt toxins expressed (Cry1 types and Vip3A for caterpillars, Cry3 types for rootworms), refuge requirement (RIB=% refuge in the bag or REF=% structured refuge) and herbicide tolerance (GLY= glyphosate /Roundup-Ready, LL=glufosinate/Liberty Link, 2,4D or group 1 ‘fops’ type herbicides). Note that older trait packages, with limited or no commercial availability, are listed, so you can look back and interpret previous year’s planting records, seed guides, and research results.
