Corn and sorghum withstood our severe weather quite well this spring, and most fields got a good start. The first cloud is now on the horizon because fall armyworm pheromone trap captures are unusually high; 7.7x the 10 year average. The graphic below shows this year's captures and the 10-year average for my traps at the Lubbock Research and Extension Center.
Whorl stage sorghum and corn take take a lot of leaf damage, perhaps 30% tissue loss before yields are affected. (This number is shaky and has little research behind it.) These big flights in late spring were uncommon prior to about four years ago, and I do not know why they are now becoming less rare.
The next question would be how our high numbers now will affect numbers in the next generation. The graphic below shows the seasonal captures in 2019, the last year we had a really high spring flight.
