Commonly used on

  • Leaf disease
  • Seed rots

Good to know

  • It works only where it lands, so it needs to go on before disease arrives.
  • Check the label on crops and re-entry intervals.
  • Hitting many sites keeps resistance risk low, but rain can wear it off and new growth is not protected.
