Understanding Lesco Pre-Emergent
Lesco pre-emergent herbicide is a type of preventive weed control that works by forming a barrier on the soil surface, preventing weed seeds from germinating. This barrier, typically composed of active ingredients such as dithiopyr or prodiamine, is applied to the lawn before the weeds have a chance to emerge. Lesco pre-emergent is designed to provide long-lasting control, often lasting several weeks or even months, depending on environmental conditions and application rates.
Benefits of Lesco Pre-Emergent
The benefits of using Lesco pre-emergent are numerous. By preventing crabgrass and other weeds from germinating, Lesco pre-emergent helps to reduce competition for water, nutrients, and light, allowing desirable turfgrasses to thrive. This can lead to a denser, healthier lawn with improved color and texture. Additionally, Lesco pre-emergent can help reduce the need for post-emergent herbicides, which can be more expensive and have a greater environmental impact.
| Active Ingredient | Formulation | Application Rate |
|---|---|---|
| Dithiopyr | Granular | 1.5-2.5 lbs/1000 sq ft |
| Prodiamine | Liquid | 1-2 quarts/acre |
Application Guidelines
Application timing is critical when using Lesco pre-emergent. In most regions, the ideal time to apply Lesco pre-emergent is between late winter and early spring, typically 2-4 weeks before the expected germination date of crabgrass. This allows the herbicide to be in place before the weeds have a chance to emerge. It’s also essential to follow the recommended application rates and guidelines for the specific Lesco pre-emergent product being used.
Calibration and Equipment Maintenance
Proper calibration and equipment maintenance are essential for effective application of Lesco pre-emergent. This includes ensuring that the spreader or sprayer is properly calibrated to deliver the recommended amount of product, as well as maintaining the equipment to prevent clogs and other issues. It’s also crucial to follow all safety precautions when handling and applying Lesco pre-emergent, including wearing protective clothing and eyewear.
