Nicosulfuron 75%WDG 40 G/L 95%TC Weedicide

Nicosulfuron is a systemic herbicide that can be absorbed by the stems, leaves, and roots of weeds. It is then translocated within the plant, causing sensitive plants to experience growth stagnation, chlorosis, and gradual death. Under normal conditions, this process takes about 20 to 25 days, but in cooler temperatures, certain perennial weeds may require a longer time to die. The herbicide is most effective when applied before the four-leaf stage; its efficacy decreases when applied to larger seedlings. This product also has pre-emergence herbicidal activity, although it is less active than its post-emergence effects.

Features of Nicosulfuron

  1. Fast efficacy.
    Generally, after application, weeds can show changes in color and wilting within 5-7 days (and will be completely dead within 20-25 days after spraying).
  2. Good residual activity.
    Nicosulfuron is a systemic, foliar herbicide. After foliar spraying, it remains effective against weeds for up to 30 days.
  3. Good rain resistance.
    Rainfall occurring 6 hours after application has no significant impact on the efficacy, so re-spraying is not necessary.
  4. Relatively safe.
    Under normal conditions, nicosulfuron does not cause adverse effects on corn or subsequent crops. However, care must be taken to avoid over-application. Excessive use can lead to injury in corn and potential issues with subsequent crops, such as reduced germination rates or residue problems.

Application

The best time to use Nicosulfuron:

  • During the 3-5 leaf stage of corn (when resistance is strongest and less prone to phytotoxicity).
  • When annual weeds are at the 2-4 leaf stage (weeds are relatively small and easier to control).
  • Before the 6 leaf stage of perennial weeds and when most weeds have emerged, the application will be most effective.

(1) Ordinary Nicosulfuron without a safener:
It is advisable not to use it when corn is below the 2 leaf stage or above the 6 leaf stage, as it is sensitive and prone to phytotoxicity. If it must be used at more than 6 leaves, it should be applied as a directed spray to avoid contacting the growing point and causing damage.

(2) Nicosulfuronwith a safener:
Compared to ordinary Nicosulfuron, this formulation is relatively safer and can be used after the 5 leaf stage. However, the effectiveness of weed control decreases as the application is delayed, so it is recommended to use it during the 3-5 leaf stage.
