Definition: Problem weeds are undesirable and often very aggressive
Why: If weeds are not controlled they can cause sight distance problems. Weeds are competitive with desirable vegetation and may spread to adjacent land.
Primary Targets:
1. Hemlock - A tall-growing, white-flowering succulent plant with fernlike foliage near the base of the plant
2. Chicory - A plant that typically grows along the edge of pavements with a blue flower that opens and closes daily
3. Phragmites - Extremely tall, reed looking plant that grows in wet areas
4. Sericea Lespedeza - An erect, shrub-like woody stemmed plant that grows three to six ft. tall
Methods:
A. Calibration
B. Use recommended products and rates
Table 821.19 Recommended Products and Rates
| Weed | Herbicide | Broadcast Rate | Handgun Rate | Surfactant |
|---|---|---|---|---|
| Hemlock | Escort | 0.5 oz. per acre | 1/2 oz. | Label |
| Milestone VM | 5 - 7 oz. per acre | 5 - 7 oz. | Label | |
| Chicory | Escort | 1/3 oz. per acre | - | Label |
| Perspective | 3 oz. / acre | 3 oz. per 100 | Label | |
| Phragmites | Aquatic glyphosate | 2 qt. per acre | 2% solution | Label |
| Sericea Lespedeza | Escort | 1/2 oz. per acre | 1/2 oz. | Label |
| Method | 8 oz. per acre | 8 oz. | Label |
C. PPE
Follow label recommendations for each product
D. When to apply
Apply when actively growing. The earlier in the growth stage the better, i.e. rosette stage on most plants. Sericea applications appear to provide better control in a late fall (Sept.) application when plant is blooming.
How to Apply:
1. Handgun
2. Boom Sprayer
3. Hand sprayer / Backpack
4. Injection sprayer
Special Recommendations:
A. Read the label
B. Chicory - Broadcast spray along shoulders in early May with Escort or Perspective for season-long control.
