Opposite page: Plants with insufficient chloride show chlorotic and necrotic spotting along leaves with abrupt boundaries between dead and live tissue. Leaves wilting at margins and highly branched root systems are also typical chloride deficient symptoms, found mainly in cereal crops (Mengel & Kirkby, 2001). Chloride deficiencies are highly cultivar-specific and can be easily mistaken for leaf diseases.

Chloride deficiency and toxicity can be a real problem
