UPL Spruce Herbicide:
Advanced Pre-Emergence Weed Control for Modern Farming
UPL Spruce is a highly effective pre-emergence herbicide powered by Pyroxasulfone 85% WG, designed to provide long-lasting control of difficult grasses and broad-leaf weeds. It works by inhibiting the early growth processes of weeds, stopping them before they emerge from the soil. Because of its strong residual activity and selective crop safety, Spruce has become a reliable weed-management tool for crops like soybean, maize, wheat, and other field crops.
Pyroxasulfone belongs to the isoxazoline class of herbicides and works by inhibiting very long chain fatty acid (VLCFA) synthesis in weeds. This stops cell membrane formation in germinating weeds, preventing them from establishing in the field. The result is cleaner fields during the critical early growth stages of crops, which ultimately leads to better crop establishment and higher yields.

Spruce Herbicide Features and Benefits
Long Residual Weed Control
Spruce provides extended soil residual activity, controlling weeds for several weeks after application and reducing the need for repeated herbicide sprays.
Broad Spectrum Weed Control
Effectively controls a wide range of annual grasses and certain broad-leaf weeds, making it suitable for integrated weed management programs.
Pre-Emergence Protection
Targets weeds at the germination stage, ensuring crops get a weed-free start during the most critical growth period.
Advanced Chemistry (Pyroxasulfone)
A modern herbicide molecule known for its high potency at low doses and strong activity against resistant grass weeds.
Improves Crop Yield Potential
By eliminating early competition from weeds for nutrients, water, and sunlight, crops grow healthier and more uniformly.
Rainfast Soil Activity
Once activated in soil, the herbicide remains effective and continues to suppress weed emergence.
Usage and Crop Recommendations
| Crop | Target Weeds | Dosage/ha (g) | Dilution in Water (L/Ha) | Waiting Period (Days) |
|---|---|---|---|---|
| Soybean | Annual grasses, broadleaf weeds | 100 – 150 g | 500 L | As per label |
| Maize | Grass weeds, annual broadleaf weeds | 100 – 150 g | 500 L | As per label |
| Wheat | Annual grasses | 100 – 120 g | 400 – 500 L | As per label |
| Cotton | Early emerging grasses & broadleaf weeds | 120 – 150 g | 500 L | As per label |
Application Timing: Apply pre-emergence immediately after sowing but before weed germination.
Method of Application: Uniform soil surface spray using a knapsack or power sprayer.
Safety and Handling
Chemical Toxicity: Follow label instructions and recommended safety measures.
Protective Gear: Use gloves, mask, and protective clothing while spraying.
Storage: Store in a cool, dry place away from direct sunlight and children.
