Hail Damage and Japanese Beetles Return

It was sad to see several get hit with devastating hail for a second year in a row from the July 4th storm. It was also such a blessing to get the unexpected gift of a fairly widespread 1"+ rain last Friday morning!

For those dealing with hail, I don't have any great new ideas for planting into totaled crops beyond soybeans or some type of forage crop at this point. For replanting with soybeans, we suggest 0.5-1.0 maturity less than you normally plant, make sure you have a fungicide seed treatment (wouldn't have to have anything for SDS, just for seedling diseases), increase your seeding rate, and consider narrower rows to close canopy quicker. Phytophthora root rot is something

I tend to see fairly often with replant soybeans, thus the rec for the fungicide seed treatment. For acres damaged on fringes, I recommend leaving existing soybean stands of 50K, which is trickier now that we're at R2-R3 in many fields. In corn fields with less damage, we will have to watch what happens on timing of silks/tassels.

For those interested in planting annual forages in July or August after hail/ drought/wheat harvest, the following contains more info. on seeding rates, tonnage, species, etc.: https://go.unl.edu/ ypgc.

Annual Forage Insurance is an opportunity for obtaining crop insurance (in Nebraska, Kansas, South Dakota) to protect against the primary production risk of low precipitation. This is for annual forage crops used for grazing, haying, grazing/haying, green chop, grain/grazing, grazing/ green chop, or silage. The current sign up period ends July 15 for coverage on annual forage planted from July 16, 2023-July 15, 2024. This insurance uses the two-month rainfall index intervals with coverage up to 90% of normal precipitation (similar to perennial forage insurance).

Japanese beetles

Adults emerge from grassy areas (lawns, pastures, road-side ditches for at least 4-6 weeks (last year was around 10). So, even if you treat, they can come back. Threshold is 30% defoliation on vegetative corn. Upon silking, the threshold is 3 or more beetles/ear with silks clipped to less than ½ inch and pollination is less than 50% complete. For soybeans the threshold upon reaching flowering is 20%defoliation (watch for pod clipping too). More info. on chemical options for crops at: https://go.unl. edu/osyi. The following are chemical options for landscapes/fruits/gardens: https://go.unl.edu/ bke4. The hardest thing has been to tell people they can't eat produce or fruit from using products that weren't labeled for the plants they applied to. Crazy how many livestock and crop products were used in landscapes last year….please follow pesticide labels.

We know how uneven these corn fields are-even irrigated ones. Many labels specify no NIS between V8/V10 till Tassel. Even if applying 'at tassel', realize that not all plants in the field will be at tassel, so you run the risk of abnormal ear development with the wrong adjuvants/ surfactants present. If disease/insect pressure doesn't warrant an app, I prefer delaying till at least brown silk to apply products to help alleviate any potential risk. I tend to be called out to many field problems. Since I started talking about this, the number of calls with messed up ears due to wrong timing of application the past three years has dwindled significantly. So, just a consideration as we begin to see more tassels shooting.

Western Bean Cutworm

It's recommended to start scouting when 25% of moth flight occurs based on a GDD model. Lincoln hit 25% on July 2nd, Grand Island July 6, Columbus July 7, York July 8th, Clay Center July 10th. Threshold is 5-8% egg masses/ live larvae. You can learn more about the GDD prediction tool and predictions for your area at: https://go.unl.edu/438o.
