Homeowner applied pre-emergent herbicide (Pendimethalin) in spring but it failed to prevent weeds (black medic, dandelions), leading to frustration after years of effort.

Workarounds Described

• sprayed entire yard with 2-4D/quinclorac/dicamba/sulfentrazone without soil testing
• put down Pendimethalin hoping it would work without checking timing/resistance
• applied Scott's moss control as a fix-all despite no moss in most of yard

Implied Software Gaps

• Diagnostic tool that evaluates product efficacy based on local conditions
• Personalized calendar with reminders for pre-emergent and post-emergent based on weather and weed lifecycle
• Soil test integration to recommend proper products and application rates
