Figure 11. Chlorine deficiency and toxicity are hard to identify in the field. Chlorine deficiency causes abnormally short roots and increases the number of lateral roots. Chlorine toxicity will also cause abnormally short roots with very little lateral branching (from left to right: 0, 1, and 100 ppm Cl). Neither Cl deficiency nor toxicity are likely in commercially-grown sugarcane in Florida.
