Green foxtail is a summer annual grassy weed. It is often found in lawns that are patchy and thin. It is also found in pastures, along roadsides, and gardens. When green foxtail is young it is often mistaken for crabgrass so be careful when identifying. The easiest way to identify green foxtail is by its fuzzy, ‘foxtail’-like seed head that can reach up to 6 inches in length. The foxtail creates thousands of seeds which makes it a difficult weed to control. Stems of this weed can reach up to 3 feet tall.
- Two weeks before green foxtail germinates use a pre emergent herbicide that contains one of the following benefin, bensulide, dithiopyr, oryzalin, pendimethalin, or prodiamine. Be sure to water the herbicide into the lawn. If the spring application does not take care of the problem try another application in the
- If green foxtail has already emerged out of the ground apply a post emergent herbicide. This herbicide may need to be applied more than once. Apply it after the weed has emerged from the ground but try to treat while the weed is young. Contact Us Today for a free quote!
Organic/ Cultural Control
- Sensible nitrogen fertilizer applications may reduce foxtail survival. Apply a nitrogen fertilizer to help control foxtail.
- Throughout dry spells in the spring and summer irrigate your lawn. Contact Us Today for a free quote on an irrigation system.
- Use a pH test kit to determine whether or not your lawn is at the correct pH level. If the pH level of a lawn is overlooked it may cause excessive amount of thatch, disease, insect problems, and an abundance of weeds. The pH level for Kentucky bluegrass should be around 6.5 and 7. If the pH is lower than 6.5 the soil is acidic and lime should be added. IF the pH level is above 7.5 the soil is considered alkaline and sulfur should be added for the soil to be neutral (7).
- If small amounts of green foxtail exist, hand pulling is an effect method of removal.
