Early detection tips for managing insect pests

By Blake Jackson

Early detection is key to managing insect pests in your fields, according to University of Missouri Extension entomologist Ivair Valmorbida. Regularly scouting your crops throughout the growing season allows you to identify problems early and take targeted action.

Weekly scouting during the growing season helps producers identify and manage problems for early intervention, Valmorbida says. He advises more frequent monitoring when weather favors rapid development of specific insect pests.

Accurate pest identification is crucial. Mistaking one insect for another can lead to using the wrong control methods, harming beneficial insects you want around, and wasting money on ineffective solutions.

The University of Missouri Extension offers a Plant Diagnostic Clinic to help with identification. They can analyze plant samples you submit. Find more information at https://extension.missouri.edu/programs/plant-diagnostic-clinic or call 573-882-3019. The clinic is also located on the MU campus.

By scouting regularly, you can make informed decisions about pest control. Valmorbida advises against using insecticides unless absolutely necessary. Keeping detailed scouting records allows you to track pest populations over time and make informed decisions for future seasons.

Forget about simply driving by the field edges for a quick check. This "windshield scouting" won't give you an accurate picture. Insect pests can be concentrated in specific areas or dwell deeper within the plant canopy.

Valmorbida recommends dividing large fields into manageable sections (40-50 acres) and following a systematic walking pattern to thoroughly cover the entire area. Avoid focusing on areas that seem particularly good or bad, and don't always start at the same spot.

Remember, pests often move from field borders inwards. When you find an issue, assess if it's isolated or widespread. Finally, when estimating damage, consider the entire plant canopy, not just the leaves you can easily see.

By following these tips and incorporating regular scouting into your routine, you can keep insect pests under control, protect your crops, and maximize your yields and profits.
