Advantages and disadvantages of Nicosulfuron
1. Advantages of Nicosulfuron
(1) Double control of grass and broadleaf weeds. Nicosulfuron is used in corn fields and has a good control effect on annual grass and broadleaf weeds.
(2) Thorough weed control. Nicosulfuron is a thorough weed control with no rebound and is systemic. After application, if it rains within 6 hours, there is no need to re-spray.
(3) High safety. Nicosulfuron is used in corn fields before the corn has 5 leaves and a heart, and after the corn has 3 leaves and a heart, the corn is safest.
2. Disadvantages of Nicosulfuron
(1) Slow weed control. Nicosulfuron is systemic and has a slow weed control speed. It takes about 10 days to see signs of weed poisoning. It takes about 20 days for the weeds to dry up and die.
(2) Poor control effect on large weeds. The best application period for Nicosulfuron is when the weeds are 4 leaves old. The older the weeds are, the worse the weed control effect is.
Precautions for using Nicosulfuron
1. Avoid high temperatures. Using Nicosulfuron under high temperatures is very likely to cause pesticide damage. It is recommended to use it after 5 pm.
2. Use with caution on sweet corn, glutinous corn, popcorn, and seed corn.
3. Corn treated with organophosphorus agents is sensitive to this agent. The interval between the use of the two agents is about 7 days.
The above is an introduction to what weeds Nicosulfuron mainly kills. Nicosulfuron is a common herbicide in corn fields and is effective against many weeds.
