Active ingredient
Dithiopyr is the active ingredient in dimension pre-emergent herbicide. It is a selective herbicide that targets and kills weed seeds before they germinate and emerge from the soil. Dithiopyr works by inhibiting the growth of the root and shoot of the weed seedling. This prevents the weed from establishing itself in the soil and competing with desirable plants for water, nutrients, and sunlight.
Dithiopyr is an effective herbicide for controlling a wide range of grassy weeds, including crabgrass, foxtail, and goosegrass. It is commonly used in lawns, gardens, and other areas where weeds are a problem.
Dithiopyr is relatively safe for use around people and pets when used according to the label directions. It is important to avoid contact with skin and eyes, and to follow all label directions when applying dithiopyr.
Table: Dithiopyr and Dimension Pre-Emergent
| Characteristic | Dithiopyr | Dimension Pre-Emergent |
|---|---|---|
| Active ingredient | Yes | Yes |
| Target weeds | Grassy weeds, including crabgrass, foxtail, and goosegrass | Grassy weeds, including crabgrass, foxtail, and goosegrass |
| Application rate | 0.25 to 0.5 ounces per 1,000 square feet | 0.25 to 0.5 ounces per 1,000 square feet |
| Application timing | Early spring or fall, before weeds germinate | Early spring or fall, before weeds germinate |
| Mode of action | Prevents weed seeds from absorbing moisture and germinating | Prevents weed seeds from absorbing moisture and germinating |
Conclusion
Dithiopyr is an important active ingredient in dimension pre-emergent herbicide. It is effective for controlling a wide range of grassy weeds, and it is relatively safe for use around people and pets when used according to the label directions.
Target weeds
Dimension pre-emergent herbicide is specifically designed to target and control grassy weeds, including crabgrass, foxtail, and goosegrass. These weeds are common in lawns and gardens, and they can quickly take over if not controlled. Dimension pre-emergent works by preventing the seeds of these weeds from germinating and emerging from the soil.
- Crabgrass is a warm-season annual grass that spreads by seed and stolons. It has a low, spreading growth habit and forms dense mats that can quickly crowd out other plants. Crabgrass is one of the most common weeds in lawns and gardens, and it can be difficult to control once it has become established.
- Foxtail is another warm-season annual grass that spreads by seed. It has a tall, upright growth habit and produces seed heads that resemble the tail of a fox. Foxtail is a common weed in lawns, gardens, and other areas with moist soil.
- Goosegrass is a warm-season perennial grass that spreads by seed and rhizomes. It has a low, spreading growth habit and forms dense mats that can quickly crowd out other plants. Goosegrass is a common weed in lawns, gardens, and other areas with moist soil.
Dimension pre-emergent is an effective way to control these grassy weeds and prevent them from taking over your lawn or garden. It is important to apply dimension pre-emergent before the weeds have a chance to germinate and emerge from the soil. Once the weeds have emerged, they will be more difficult to control.
Application rate
The application rate of dimension pre-emergent herbicide is critical to its effectiveness. Too little herbicide will not be effective in controlling weeds, while too much herbicide can damage plants and the environment. The application rate for dimension pre-emergent is 0.25 to 0.5 ounces per 1,000 square feet. This rate has been carefully calibrated to provide effective weed control without causing damage to plants or the environment.
It is important to follow the application rate on the herbicide label. Applying too much herbicide can damage plants and the environment. It is also important to calibrate your sprayer to ensure that you are applying the correct amount of herbicide.
Dimension pre-emergent herbicide is a safe and effective way to control weeds in your lawn or garden. By following the application rate on the herbicide label, you can ensure that you are using the herbicide safely and effectively.
| Application rate | Effect |
|---|---|
| Too little herbicide | Not effective in controlling weeds |
| 0.25 to 0.5 ounces per 1,000 square feet | Effective weed control without causing damage to plants or the environment |
| Too much herbicide | Damage to plants and the environment |
By understanding the connection between the application rate and the effectiveness of dimension pre-emergent herbicide, you can use this product safely and effectively to control weeds in your lawn or garden.
Application timing
Dimension pre-emergent herbicide is most effective when applied in early spring or fall, before weeds germinate. This is because dimension pre-emergent works by preventing weed seeds from absorbing moisture and germinating. If the herbicide is applied after the weeds have already germinated, it will not be as effective.
It is important to follow the application timing on the herbicide label. Applying dimension pre-emergent too early or too late can reduce its effectiveness. For example, if you apply the herbicide too early, it may break down before the weed seeds germinate. If you apply the herbicide too late, the weed seeds may already have germinated and emerged from the soil, making them more difficult to control.
By understanding the connection between application timing and the effectiveness of dimension pre-emergent herbicide, you can use this product safely and effectively to control weeds in your lawn or garden.
| Application timing | Effect |
|---|---|
| Too early | The herbicide may break down before the weed seeds germinate. |
| Early spring or fall, before weeds germinate | The herbicide is most effective when applied before the weed seeds germinate. |
| Too late | The weed seeds may already have germinated and emerged from the soil, making them more difficult to control. |
By understanding the connection between application timing and the effectiveness of dimension pre-emergent herbicide, you can use this product safely and effectively to control weeds in your lawn or garden.
Mode of action
Dimension pre-emergent herbicide works by preventing weed seeds from absorbing moisture and germinating. This is a unique mode of action that sets dimension pre-emergent apart from other herbicides. Most herbicides work by killing weeds after they have emerged from the soil. However, dimension pre-emergent prevents weeds from germinating in the first place.
- Inhibition of water absorption: Dimension pre-emergent herbicide creates a barrier in the soil that prevents weed seeds from absorbing moisture. This barrier is formed by the active ingredient in dimension pre-emergent, dithiopyr. Dithiopyr binds to the surface of weed seeds and prevents them from taking up water. Without water, weed seeds cannot germinate and grow.
- Prevention of root and shoot growth: Once dimension pre-emergent has prevented weed seeds from absorbing moisture, it also prevents them from developing roots and shoots. This is because dithiopyr also inhibits the growth of plant cells. Without roots and shoots, weed seedlings cannot establish themselves in the soil and grow into mature plants.
- Long-lasting control: Dimension pre-emergent herbicide provides long-lasting control of weeds. This is because it remains active in the soil for up to four months. This means that it can prevent weeds from germinating and growing for an extended period of time.
Dimension pre-emergent herbicide is a safe and effective way to control weeds in your lawn or garden. It is important to follow the application instructions on the herbicide label to ensure that you are using the product safely and effectively.

- Pendimethalin: Pendimethalin is a pre-emergent herbicide that is similar to dimension pre-emergent in terms of its mode of action and effectiveness. However, pendimethalin has a shorter residual period than dimension pre-emergent, meaning that it does not last as long in the soil. This can be a disadvantage if you are looking for long-term weed control.
- Benefin: Benefin is another pre-emergent herbicide that is similar to dimension pre-emergent in terms of its mode of action and effectiveness. However, benefin is more likely to cause injury to desirable plants than dimension pre-emergent. Therefore, it is important to use benefin carefully and according to the label directions.
