Application and Usage of Pendimethalin Herbicide

Pendimethalin, also known as Stomp, Pendulum, or Prowl, is an excellent herbicide with remarkable effectiveness against various weeds. Here is an overview of the application range and usage methods of Pendimethalin herbicide.

Application Range of Pendimethalin Herbicide

Pendimethalin is a dinitroaniline herbicide used as a contact soil-applied pre-emergent treatment. It is widely used in agriculture for controlling weeds in rice, cotton, corn, tobacco, peanuts, vegetables, and orchards. It is effective against annual grasses and some broadleaf weeds such as barnyardgrass, foxtail, crabgrass, bluegrass, lambsquarters, pigweed, chickweed, knotweed, shepherd's purse, and sedges.

Usage Methods of Pendimethalin Herbicide

1. Corn

Apply Pendimethalin 180-200 ml per acre 1-3 days before sowing. Use 40-60 liters of water per acre to evenly spray the soil surface, followed by shallow soil mixing.

2. Tobacco

Pendimethalin can be used to suppress tobacco axillary buds. When 50% of the tobacco plants show budding, top them, and apply the herbicide on the same day. Use a 33% Pendimethalin emulsifiable concentrate diluted 80-100 times, spraying 20-25 ml per plant to ensure the liquid flows evenly down the stem, touching every leaf axil.

3. Soybeans

For spring soybeans, apply 200-300 ml of 33% Pendimethalin emulsifiable concentrate per acre, mixed with 15-20 kg of water, and apply to the soil after preparing the land, then sow. For summer soybeans, apply 150-200 ml of 33% Pendimethalin emulsifiable concentrate per acre, mixed with 15-20 kg of water, and spray the soil surface 1-2 days after sowing. Applying the herbicide too late can cause phytotoxicity.

4. Vegetables

For direct-seeded crops like garlic, ginger, carrots, chives, onions, and celery, apply 100-150 ml of 33% Pendimethalin emulsifiable concentrate per acre, mixed with 15-20 kg of water, and spray the soil surface after sowing and covering with soil.

Precautions for Using Pendimethalin Herbicide

  1. It is best to apply the herbicide before or immediately after sowing or transplanting, as applying it to mature weeds can cause phytotoxicity.

  2. Water the soil before applying the herbicide to enhance absorption, and avoid overusing the herbicide.

  3. Use Pendimethalin in recommended dosages, and do not arbitrarily increase the amount.

  4. Ensure seeds are sown at a depth of 3-5 cm to avoid herbicide damage.

  5. Do not apply the herbicide when there is dew in the morning or when temperatures exceed 30-35°C.

  6. Pendimethalin is highly toxic to fish, so take precautions when using it near water bodies.

Pendimethalin is a commonly used herbicide with excellent results against various weeds. When using it, be sure to follow the precautions mentioned above to avoid any adverse effects.
