| IPM Compatibility: |
Per Requester: Good Fit; There are no anticipated risks to endangered or threatened species or beneficial organisms. Crop rotation is a key component of IPM. Sorghum is used in rotation with wheat in Kansas and other states. While seed treatments provide some early-season protection against chinch bugs in Kansas, they lack the residual efficacy needed to prevent damage during prolonged infestations. In many cases, seedling stands on field perimeters are reduced by up to 100% due to early infestations, often requiring rescue treatments with foliar insecticides to avoid complete stand loss. As the season progresses, infestation pressure continues, revealing a clear gap in effective chemical control options. Current evaluations of labeled insecticides have shown limited efficacy, particularly under heavy pest pressure early season. Field trials last year assessed the efficacy of bifenthrin in multiple small and large-scale production fields, and results to date demonstrated promising control using bifenthrin:06/

| Reasons for need: |
Chinch bug. Chinch bug (Blissus leucopterus) is becoming an increasing issue in grain sorghum in central Kansas, destroying 1,000s of acres in 2023 and 2024. In some fields seedlings were destroyed requiring replanting, while in other fields yields were significantly reduced. Unfortunately, labeled pesticides will not sufficiently control chinch bug:06/25;

| Comments: |
X-ref 08587 rec'd in 2002, noted for "seed production", and removed from nominations in 2015 due to no nominations in 3 consecutive years. Key Export Markets: China, Spain, Mexico:06/25; May require a weight of evidence as Sorghum is not a specialty crop. But appears in public interest due to “control of a niche pest on a major crop (where acres treated is = 300,000 acres)”;
