Soil sickness, replant problem or replant disease and its integrated control

The problem of establishing new crops on old sites is known as Replant Problem, Replant Disease, or Soil Sickness. There is confusion about the terminology of “Replant Problems”, Replant Disease, or “Soil Sickness”. The term “soil sickness” may be used for all problems (replant disease, replant problem, or soil sickness) relating to establishing new crop on old sites and to avoid all confusions about various terminologies. Sufficient research has been done on chemical control with fumigation, however, research is needed to develop cultural and biological methods and to breed disease resistant or tolerant crops. There is also need to develop an integrated pest management approach combining cultural and biological control with host resistance. Various strategies to protect new crops from soil sickness to produce higher yields at lower cost, with minimum risk to producers, consumers and the environment are discussed in this paper.
