Rainfall and Insecticide Efficacy
With the increase of rain showers this week and tarnished plant bug numbers starting to pick up in some places, now is a good time to revisit the impact of rainfall on insecticide performance. Rainfastness is a complex topic because
Southwestern Corn Borer Traps, July 4, 2020
Trap counts for southwestern corn borer are highly variable this week. We did have two locations in Tate and Leflore Counties that exceeded the threshold this week. As a reminder, thresholds for southwestern corn borer suggest spraying non-Bt corn 7
Heliothine Trap Counts, July 2, 2020
Bollworm pheromone trap catches were higher than long-term averages again this week as they have been all year, while tobacco budworm catches were about the same as long-term averages. As most corn is advancing past the green silk stage, more
Corn Reproductive Stages and Their Management Implications
Corn progresses through six stages as ears develop through reproductive growth stages. Identification of these stages can be helpful for timing development, making prudent management decisions and anticipating crop response to practices and environmental conditions.
Rice Flood, It’s Okay to Let it Down
AWD is a water-saving technology that farmers can use to reduce the amount of irrigation water used in rice fields without any yield penalty. In AWD, farmers allow the flood water to recede to a “muddy” state before re-flooding the
