Sheath rot (Busuk pelepah)

23 March 2022
4 mins read

Infection occurs in the upper leaf sheath covering the young panicle at the end of the pregnant phase. The initial symptom is the presence of an elongated to irregular round spot with a length of 0.5-1.5cm, gray in the center and brown or gray-brown at the edges. The spots are enlarged, often continuous, and can cover the entire leaf midrib. Severe infection causes the panicles to appear only partially (not growing) and shrivel up. Partially emerging panicles can produce only a few filled grains. The plant’s most susceptible stage is when the panicle leaves until the milk matures. Midrib rot can be controlled by:

  • Burn the stump immediately after harvest to reduce inoculum.
  • Adjust the spacing so that it is not too tight.
  • Give K fertilizer at the tillering phase.
  • Spraying of fungicides on leaves is only carried out when necessary, namely in the pregnant phase, and treatment of seeds with fungicides with active ingredients of carbendazim or mankozeb to reduce disease infection.
  • Spraying with fungicides (if needed) with active ingredients Benomyl is also effective in suppressing infectious diseases.
