Pepino mosaic virus (strain CH2, isolate Abp2)

Pepino mosaic virus (strain CH2, isolate Abp2) is a biological agent used in professional greenhouse horticulture. It is not a chemical pesticide, but rather a mild virus isolate specifically selected to provide cross-protection against more virulent and damaging strains of the Pepino mosaic virus (PepMV).

The mechanism of action functions similarly to a vaccine in animals. By deliberately infecting tomato plants with the mild Abp2 isolate, the plant's defense systems are triggered. This induced immunity prevents subsequent infection by aggressive wild-type strains of PepMV, which could otherwise severely reduce fruit quality and yield.

This biological control agent is primarily used for tomato cultivation. It targets the prevention of characteristic PepMV symptoms, such as leaf discoloration, fruit mottle, and distortion, which cause significant economic losses in the greenhouse industry globally.

Application requires high precision and strict adherence to agrotechnical protocols. The inoculum is applied to young plants during the nursery stage. It is crucial to ensure that every single plant in the crop is successfully inoculated to prevent the development of unprotected clusters that could become focal points for aggressive virus outbreaks.

Safety precautions are mandatory when handling this biological agent. Strict biosecurity measures must be in place to prevent the spread of the virus to unintended areas or susceptible crops like peppers or eggplants. Tools, clothing, and equipment must be disinfected regularly, and unauthorized movement between treated and non-treated greenhouses must be restricted.
