The MFA agronomy team reported on April 22 that spring crops, weeds, and insects are developing much faster than usual this year due to unusually high growing degree units across the region. Senior Staff Agronomist Scott Wilburn said that Mexico, Missouri had accumulated 711 growing degree units by April 16, compared to a long-term average of 213 for the same date. Recent years with warm springs also trailed behind these numbers.
This accelerated pace means farmers need to adjust their management timelines by about three weeks ahead of normal for heat-driven plant growth and insect activity. Early emergence of pests such as June bugs has already been observed, which typically do not appear until May. “While the adult beetles typically cause little concern, as opposed to their larva, which is an underground pest, their early presence reinforces the need for close scouting other species,” Wilburn said.
Persistent southerly winds and abundant heat have contributed to these conditions. Farmers are advised to monitor all crops closely for weed and pest pressure—including hay and pasture—since cutworms and armyworms can cause rapid damage if not addressed quickly. Wet weather has complicated matters further by delaying planting in many areas along the I-70 corridor and northern parts of the state. In contrast, some southern regions have seen record progress in corn and soybean planting this season; District Agronomist Jesse Surface noted he had never seen such advanced crop development at this time before.
MFA recommends flexibility as key during fast-moving seasons like this one. Adjustments may be necessary as field conditions change rapidly; careful monitoring is needed so critical application windows are not missed. For fields still awaiting planting, waiting until soil temperature, moisture, and structure are suitable remains important for success regardless of calendar date. “Regardless of the calendar date, it’s important to plant when soil conditions are right,” said Doug Spaunhorst, MFA director of agronomy services.
MFA supports profitable and sustainable farming practices aimed at strengthening rural communities according to its official website. The organization functions as a farmer-owned cooperative serving more than 45,000 farmer-owners according to its official website, with economic benefits provided through cooperative purchasing and sales according to its official website. Governance is provided by a board of fourteen elected farmers who represent owner interests according to its official website.
Serving Missouri farmers as well as those in neighboring Midwest states according to its official website, MFA was established in 1914 offering agronomy services alongside livestock nutrition solutions, grain marketing support and farm supplies while focusing on sustainable operations that benefit both owners’ profitability and community development according to its official website.
