| Integrated Pest Management Control Recommendations: |
Cultural Practices:
Horsetail is a summer perennial that thrives in moist or springy grasslands.
Horsetail out competes other plants due it ability to live in wet soils.
To culturally control horsetail, correct the drainage. Low mowing of the
horsetail prevents it ability to spread. Fertilize the turf to increase
it ability to compete with the horsetail.
Herbicide Use:
For best results, apply your post-emergent herbicide when horsetail is
young and actively growing, before spore heads are formed.
