A tiny pest known as the wheat curl mite is causing significant problems for some Oklahoma wheat farmers, according to officials from the Oklahoma State University Extension Office. The wheat curl mite can damage wheat crops by feeding on the plants and transmitting viruses.

Why it matters

Wheat is a crucial agricultural crop in Oklahoma, with the state ranking among the top producers nationwide. Infestations of the wheat curl mite have the potential to severely impact wheat yields and profitability for local farmers, threatening an important part of the state's economy.

The details

The wheat curl mite is an extremely small pest, measuring less than 1/100th of an inch in size. Despite their tiny stature, these mites can cause extensive damage to wheat plants by feeding on the leaves and stems. They also transmit viruses that further weaken and stunt the growth of the wheat. Oklahoma State University experts are advising farmers to closely monitor their fields for signs of the wheat curl mite and take appropriate mitigation steps.

  • The wheat curl mite activity was first detected in Oklahoma in late March 2026.
