What is one of the best ways to limit clover mite injury?

• A. Provide adequate water to high-risk sites
• B. Increase nitrogen fertilizer
• C. Apply pesticides monthly
• D. Remove irrigation

Answer: (A)

Clover mites cause the most damage when turf is drought-stressed. Keeping high-risk areas adequately watered helps maintain plant vigor and cell turgor, making the grass less susceptible to mite feeding and the characteristic bronzing or stippling. Proper irrigation reduces the hot, dry microclimates that mites prefer and limits the tissue they can attack, which directly lowers injury levels. Increasing nitrogen promotes rapid, tender growth and does not address the underlying water stress, and can even invite other pest issues. Monthly pesticide applications don’t fix the stress condition and can disrupt beneficial organisms, while removing irrigation only worsens drought stress. So, ensuring sufficient, appropriate watering is the most effective way to limit clover mite injury.
