Aphids are small bugs that like to munch on plants, including corn. Recently, these little insects have been seen in Iowa's cornfields. Farmers are being told to watch out and take some easy steps to keep their corn safe.
Aphids can hurt corn in different ways. They suck juice from the leaves and stems, which can make the plant weak and sick. They also leave behind a gooey stuff called honeydew that attracts other pests. In bad cases, aphids can eat so much that the corn leaves disappear!
If you see aphids in your cornfield, don't wait. Act quickly. There are special sprays that can help, but make sure they're safe for corn. Follow the instructions on the packaging to make sure it is safe for use in your circumstances.
Here are some tips for monitoring your cornfields for aphids:
• Routine Checks: Regularly inspect your fields, especially during periods of hot and dry weather, when aphid infestations are more likely to occur.
• Targeted Locations: Pay close attention to the undersides of leaves, the base of stalks, and the areas around the ears, as aphids tend to congregate in these spots.
• Use a Magnifying Glass: Utilize a magnifying glass to get a clear view of the insects. Although small, aphids are typically identifiable upon closer examination.
• Quantify the Infestation: Should aphids be present, count the number of insects on ten plants. If the tally exceeds 20 aphids per plant, it may be necessary to implement treatment strategies.
By checking for aphids and taking quick steps, you can protect your corn from harm and make sure it grows strong. Remember, aphids aren't just a problem in Iowa – they're found all over the country. So, keeping an eye out is important wherever you grow corn.
