Control
Phytoplasmas are normally controlled by the breeding and planting of disease resistance varieties of crops (believed to the most economically viable option) and by the control of the insect vector.
Tissue culture can be used to produce clones of phytoplasma infected plants that are healthy. The chances of gaining healthy plants in this manner can be enhanced by the use of cryotherapy, freezing the plant samples in liquid nitrogen, before using them for tissue culture.
Work has also been carried out investigating the effectiveness of plantibodies targeted against phytoplasmas.
Tetracyclines are bacteriostatic to phytoplasmas, that is they inhibit their growth. However, without continuous use of the antibiotic, disease symptoms will reappear. Thus, tetracycline is not a viable control agent in agriculture, but it is used to protect ornamental coconut trees.

Famous quotes containing the word control:
“Men who have been raised violently have every reason to believe it is appropriate for them to control others through violence; they feel no compunction over being violent to women, children, and one another.”

“The awareness that health is dependent upon habits that we control makes us the first generation in history that to a large extent determines its own destiny.”

“Every expansion of government in business means that government in order to protect itself from the political consequences of its errors and wrongs is driven irresistibly without peace to greater and greater control of the nation’s press and platform. Free speech does not live many hours after free industry and free commerce die.”
—Herbert Hoover (1874–1964)
