SWAL Herbicide Range and Chemical Actives
SWAL Corporation formulates registered herbicides engineered to control aggressive weed complexes in field crops and non-cropped land.
Understanding the timing and selectivity of each formulation ensures weed control without inducing crop phytotoxicity.
- Total (Sulfosulfuron 75% + Metsulfuron 5% WG): High-potency post-emergence herbicide for broadleaf and grassy weeds in wheat
- Sweep / Sweep Power (Glufosinate Ammonium): Non-selective contact herbicide for targeted weed clearance in plantation crops
- Selective weedkillers: Tailored formulations managing grass and broadleaf weeds in pulses, sugarcane, and oilseeds
Target Crops and Application Timing Windows
SWAL herbicides are applied across wheat, soybean, rice, sugarcane, and plantation crops.
Post-emergence applications should target actively growing weeds at the two to four leaf stage under favorable soil moisture conditions.
- Wheat fields: Controls Phalaris minor, Chenopodium album, and Melilotus indica post-irrigation
- Sugarcane & maize: Suppresses difficult broadleaf weeds and annual grasses during early tillering
- Orchard and non-crop: Directed sprays with protective hoods to clear dense unwanted ground vegetation
Spraying Instructions, Moisture, and Operator Safety
Apply using a well-calibrated knapsack sprayer equipped with flat fan or floodjet nozzles for uniform surface deposition.
Ensure adequate soil moisture is present during application, as moisture-stressed weeds exhibit reduced chemical absorption.
Wear standard personal protective equipment during mixing and spraying operations.
- Nozzle type: Flat fan nozzles deliver uniform coarse droplets that minimize drift onto neighboring crops
- Soil moisture: Apply when fields have good moisture to maintain active weed metabolism and uptake
- Personal protection: Wear chemical-resistant gloves, protective clothing, and eye goggles during preparation

Common questions
What is SWAL Total herbicide used for in wheat?
SWAL Total (Sulfosulfuron + Metsulfuron) is a selective post-emergence herbicide controlling both Phalaris minor and broadleaf weeds in wheat.
Why is soil moisture critical when applying post-emergence herbicides?
Moist soil ensures weeds are actively transpiring and metabolizing, facilitating rapid systemic chemical absorption and translocation.
Can SWAL non-selective herbicides be sprayed over crops?
No, non-selective herbicides like Glufosinate will damage crops and must only be used in non-crop areas or with protective spray hoods.
