Paraquat Dichloride 24% SL, marketed under the brand name "Laster," is primarily used as a herbicide in agriculture, horticulture, and other vegetation management applications. Here are some common uses of Laster:

1. Agricultural Weed Control: Laster is widely used in agriculture to control weeds in various crops such as corn, soybeans, cotton, wheat, rice, sugarcane, and others. It effectively suppresses both broadleaf and grassy weeds, helping to maintain crop yields by reducing competition.

2. Non-Crop Areas: It is utilized for weed control in non-crop areas such as fence rows, roadsides, industrial sites, and utility areas. Laster effectively manages unwanted vegetation, preventing overgrowth and maintaining clear access.

3. Orchards and Vineyards: Laster can be applied in orchards and vineyards to control weeds between tree rows and vine rows, ensuring proper growth and development of fruit-bearing plants.

4. Vegetable Production: In vegetable production systems, Laster helps control weeds that compete with crops for nutrients, water, and sunlight. It is commonly used in vegetable fields and garden plots.

5. Pasture and Rangeland Management: Laster is applied in pasture and rangeland settings to suppress weeds and undesirable vegetation, promoting healthy forage growth for grazing animals.

6. Pre-plant Weed Control: It is used as a pre-plant herbicide to eliminate existing weeds before planting crops, ensuring a weed-free environment for seed germination and early crop establishment.

7. Post-emergence Weed Control: Laster is also employed as a post-emergence herbicide, targeting weeds that have already emerged in the field. Its quick action helps in managing weed infestations during the growing season.

8. Residual Weed Control: In some cases, Laster may provide residual weed control, inhibiting weed germination and emergence for a period after application, depending on soil conditions and environmental factors.

9. Aquatic Weed Management: In certain regions, Laster is used for controlling aquatic weeds in ponds, lakes, and other water bodies, where excessive vegetation growth can impede water flow and aquatic ecosystems.

10. Integrated Weed Management (IWM): Laster can be integrated into weed management programs alongside other herbicides, cultural practices, and mechanical methods to achieve sustainable weed control while minimizing herbicide resistance and environmental impacts.
