A Detailed Guide to the Correct Use of Pendimethalin

Use 100-300 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface before crop sowing or after sowing but before emergence, or spray the soil surface 1-2 days before transplanting; the specific use method varies with different crops. It belongs to the aniline herbicide class and is widely used in cotton, corn, rice, potato, soybean, peanut, tobacco and vegetable fields.

1. Cotton: Use 150-200 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface before sowing or after sowing but before emergence. Because the weather in northern cotton areas is dry, to ensure the weeding effect, the soil must be mixed 3-5 cm after application.

2. Corn: For spring corn, use 200-300 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface after sowing but before emergence; application should be carried out within 5 days after sowing, as application too late can easily cause phytotoxicity to corn. For summer corn, use 150-200 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface after sowing but before emergence; apply within 2 days, as application too late can easily cause phytotoxicity.

3. Rice and potato: Use 150-200 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface after sowing but before emergence.

4. Rapeseed fields: For transplanted rapeseed fields, use 150-200 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface 1-2 days before transplanting.

5. Vegetable fields: For direct-seeded fields of garlic, ginger, carrot, chili pepper, Chinese chives, scallion, onion, celery, coriander and others, use 100-150 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface after sowing and covering with soil. For transplanted fields of chili pepper, tomato, Chinese chives, Welsh onion, onion, celery, cauliflower, Chinese cabbage, cabbage, eggplant and others, use 100-150 milliliters of 33% pendimethalin emulsifiable concentrate per mu, dilute with 15-20 kilograms of water, and spray the soil surface 1-2 days before transplanting.
