Sugarcane - Deformation

Symptoms
Symptoms start on younger leaves showing necrotic and partially split tips that bend down. Leaf blades are brittle, shrivelled and narrow. Irregular dark and light brown patches expand over the leaf. Translucent lesions called "water sacks" may appear between the veins and exude water droplets on the upper leaf surface. Growing points become distorted and may die. Excessive tiller growth gives the plant a bushy appearance. Growth and yield are reduced.

Reasons
Boron deficiency Boron deficiency symptoms are sometimes called "false pokkah boeng" disease. Furthermore, the spindly appearance can be confused with herbicide damage

Boron deficiency made worse by

  • Sandy soils
  • Alkaline soils
  • Soils low in organic matter
  • High levels of nitrogen
  • High levels of calcium
  • Cold wet weather
  • Periods of drought

Boron is important for

  • Cell integrity
  • Efficient uptake of Ca, K and N
  • Development of young shoots and roots
  • Low requirement of monocotyledons, susceptible to B toxicity
