Aspis, KE

Reliable Pre-emergence Protection for Sunflowers

Achieving a clean field during the early growth stages is the foundation of a high yield. "Aspis, KE" from SHANDONG QIAOCHANG CHEMICAL is a system-action herbicide designed to provide consistent control against weeds before they become a threat to your sunflower crop. It works by creating an active barrier in the topsoil, essentially stopping weed germination in its tracks.

Application and Field Performance

As a selective soil-applied herbicide, its main strength is its ability to eliminate competition from both annual grasses and broadleaf weeds without affecting the crop's development.

• Dosage: The application rate ranges from 1.5 to 3 L/ha. Adjusting the rate according to soil texture (lower for sandy, higher for clay-heavy soils) is essential for optimal weed control.
• Methodology: It is a pre-emergence product, meaning it must be applied to well-prepared soil. The soil surface should be fine-textured to ensure the herbicide forms an even, unbroken barrier.
• Efficiency: With a maximum of one treatment per season, it simplifies farm management and reduces the need for repeated machinery passes.

Operational Tips and Maintenance

Because "Aspis, KE" is an emulsifiable concentrate, maintenance of your sprayer is crucial. The oily formulation can leave residues on tank walls and hoses, so thorough cleaning immediately after operation is recommended to prevent nozzle clogging. As it is classified as a Category 2 hazardous substance, always use appropriate personal protective equipment (PPE) during handling and mixing.

For the best results, timing is everything. Soil moisture is the key activator for this product. If the field is too dry during application, the herbicide may not integrate well into the soil profile. Plan your application to coincide with periods of expected moisture to maximize the product’s systemic action and ensure long-lasting crop protection.
