  • This herbicide can only be used for rice field weed control. Please do not used for other crops.
  • This herbicide can be used from post-emergence till booting stage, application to Echinochloa at 5-leaf stage can achieve the best effect.
  • In transplanting rice field and Direct Casting-Planted Rice Field, herbicide should be applied at transplanting or 15 days later after casting-planted, at when the seeding turns green. This can avoid poor resistance and phytotoxicity.
  • Drain water and make the weeds show out before application, and then irrigate after two days to keep 3-5 cm water layer for 4-5 days.
  • It has better effect to use with adjuvant.
