**Mastrinate (Mesotrione + Atrazine) – Herbicide Use Guide**

1. #### **1. Purpose & Crops**
   – **Combination Herbicide**:
   – **Mesotrione** (HPPD inhibitor) – Controls broadleaf & grassy weeds.
   – **Atrazine** (Photosystem II inhibitor) – Broad-spectrum pre & post-emergence control.
   – **Main Crops**:
   – **Maize (Corn)** – Primary use.
   – **Sugarcane** – Selective weed control.
   – **Sorghum** – Limited use (check label).

#### **2. Target Weeds**
– **Broadleaf Weeds**: Pigweed, Ragweed, Lambsquarters.
– **Grassy Weeds**: Foxtail, Barnyardgrass.
– **Sedges**: Yellow Nutsedge (partial control).

#### **3. Application Rates**
| **Crop** | **Dosage (per acre)** | **Application Timing** |
|—————|———————-|———————–|
| **Maize** | 1.5–2.5 L/ha | Pre-emergence or early post-emergence (3-5 leaf stage) |
| **Sugarcane** | 1.0–2.0 L/ha | Pre-emergence or after planting (before weed emergence) |

#### **4. Key Precautions**
– **Soil Type**: Works best in loamy soils; less effective in sandy/organic soils.
– **Rainfall**: Requires moisture for activation (avoid heavy rain after application).
– **PHI (Pre-Harvest Interval)**: 60–90 days (check label).
– **Rotation Restrictions**: Avoid sensitive crops (soybean, vegetables) next season.

#### **5. Resistance Management**
– Rotate with **glyphosate** or **glufosinate** to prevent weed resistance.

#### **6. Environmental & Safety**
– **Toxicity**: Moderate (Use PPE – gloves, mask).
– **Groundwater Risk**: Atrazine may leach in sandy soils.
