[1] Trees infected with citrus blight experience a general decline in health; this includes wilting, die-back, loss of foliage, and the production of smaller/discolored fruits.

Though the spreading mechanism of the blight is not known, some sources report trees grown on the same rootstock develop concurrent infections.

[2] Another effective means of identifying citrus blight is by testing a plant's ability to take in water.

The optimal time to test if a plant is able to take on water is in the spring months, namely March, April, and May.

[1] Rates of citrus blight infection can be reduced by growing citrus-bearing trees on rootstocks that are tolerant to the disease.

[2] YARA, an American fertilizer company, notes that orchards treated with Calcium nitrate lose fewer trees to citrus blight, citing a 1995 study.

[4] A field study published by the University of Florida noted that citrus blight causes $60 million in economic damages annually.
