What is Prunus Replant Disorder?

Prunus Replant Disorder, also known as Prunus Replant Disease or PRD, occurs from planting perennial crops into soils where a complex of nematodes and soil-borne diseases are present. Tree replants, even resistant rootstock varieties, are especially prone to replant disorder.

DID YOU KNOW: Prunus Replant Disease affects roughly 60% of Prunus-to-Prunus plantings

DID YOU KNOW: Orchards suffering from replant disorder show poor, non-uniform growth and low vigor, often for the entire life of the crop. As root and vegetative growth suffers, so do yields.

When you are getting ready to plant your orchard, the health of the soil in which you’re planting, has one of the most influential impacts on early tree growth and harvest yields. Studies repeatedly show that soils fumigated with TriClor produce healthier roots that allow trees to establish themselves faster and more uniformly. This allows fertilizer and irrigation inputs to be utilized more efficiently, saving you time and money on the front end, and maximizing your harvest yields and profits on the back-end.

TriClor is a pre-plant soil fumigant and the foundation for a successful pest management system. For orchard growers, TriClor is used to effectively manage many common soil-borne diseases.

TriClor Manages a Broad Spectrum of Soil-Borne Disease:

  • Prunus Replant Disorder (PRD)
  • Nematodes
  • Phytophthora
  • Root Rot

TriClor’s Double Punch


Immediately knocks back soil borne pathogens giving plants their best start.


New studies have confirmed that TriClor’s active ingredient – Chloropicrin – acts as a selective agent, facilitating the re-colonization of beneficial soil microorganisms post application.
