How to Use Dymenox Herbicide Correctly

Dymenox, also known as Pendimethalin, is a commonly used herbicide known for its unique mechanism and broad-spectrum weed control. Let's explore the correct methods for using Dymenox herbicide.

What Weeds Does Dymenox Control?

Dymenox is effective in controlling a wide range of weeds and is suitable for crops such as rice, cotton, corn, tobacco, peanuts, vegetables (like cabbage, spinach, carrots, garlic, onions), and orchard crops. It targets annual grasses and broadleaf weeds, including barnyard grass, foxtail, crabgrass, goosegrass, pigweed, purslane, and amaranth.

Correct Methods for Using Dymenox Herbicide

Step 1: Using Dymenox in Rice Fields

In southern rice-growing regions, Dymenox is often used for pre-emergence soil treatment in direct-seeded rice:

1. Spray Dymenox before the rice seeds germinate.

2. Use 150-200 ml of 33% Dymenox emulsifiable concentrate per acre.

Step 2: Using Dymenox in Rapeseed Fields

For direct-seeded rapeseed fields:

1. Spray the soil surface after sowing and covering the seeds.

2. Use 100-150 ml of 33% Dymenox emulsifiable concentrate per acre.

For transplanted rapeseed fields:

1. Spray the soil surface 1-2 days before transplanting.

2. Use 150-200 ml of 33% Dymenox emulsifiable concentrate per acre.

Step 3: Using Dymenox in Vegetable Fields

For garlic, ginger, carrots, leeks, onions, celery, etc.:

1. Use 100-150 ml of 33% Dymenox emulsifiable concentrate per acre, mixed with 15-20 liters of water.

2. Spray the soil surface after sowing and covering the seeds.

For peppers, tomatoes, leeks, onions, cauliflower, cabbage, eggplants, etc.:

1. Use 100-150 ml of 33% Dymenox emulsifiable concentrate per acre, mixed with 15-20 liters of water.

2. Spray the soil surface 1-2 days before transplanting.

Step 4: Using Dymenox in Cotton Fields

For cotton fields:

1. Apply Dymenox before sowing cotton seeds.

2. Use 150-180 ml of 33% Dymenox emulsifiable concentrate per acre, mixed with 30-40 liters of water.

3. After spraying, mix the soil lightly (3-5 cm deep).

Step 5: Using Dymenox in Red Date Orchards

For red date orchards:

1. Apply Dymenox during the sprouting period of date trees, before weed emergence.

2. Use 200-250 ml of 33% Dymenox emulsifiable concentrate per acre.

3. Apply the herbicide with water before stopping irrigation, ensuring effective weed control.

4. Typically, apply twice per growing season, with a 40-day interval between applications.

Step 6: Using Dymenox in Corn Fields

For spring corn:

1. Use 200-300 ml of 33% Dymenox emulsifiable concentrate per acre, mixed with 15-20 liters of water.

2. Spray the soil surface within 3 days after sowing.

3. Avoid late applications to prevent crop damage.

For summer corn:

1. Use 150-200 ml of 33% Dymenox emulsifiable concentrate per acre, mixed with 15-20 liters of water.
