Overview:
As expected, weevil numbers continued their increase over the past week, with every site approaching – or passing – the 50% threshold we often look to for triggering treatment. In fact, multiple sites were sprayed prior to my visits this week and most sites will have seen an insecticide application by early next week.
Resources of interest:
• Treatment efficacy trial results can be found at (lower RH corner of the page): https://www.meadowlark.k-state.edu/crops-soils/index.html .
• Additional pest/production information can be found in the KSU Alfalfa Insect Management Guide: https://bookstore.ksre.ksu.edu/pubs/mf809.pdf
What’s Next?
With most sites likely sprayed over the next week, data next week will likely be limited. Many thanks to the cooperators who have allowed me to check fields and monitor feeding levels.
Scouting will resume post insecticide application to see how products performed – if evaluations can be done prior to the first cutting! In the meantime, drop me a line if you have any questions!
