Sharing best management practices to counter ToBRFV in glasshouse tomato

Lessons learned in the Netherlands have proven that it is possible to be effective in battling ToBRFV infections. These guidelines and best practices (BMPs) can help you succesfully grow non-ToBRFV and Intermediate (IR) resistant ToBRFV varieties.

About the virus

The Tomato Brown Rugose Fruit Virus (ToBRFV) was initially detected in Israel in 2014 and later in Jordan in 2015. However, since 2018, it has been increasingly identified in various regions worldwide.

The first signs of ToBRFV spreading beyond the Middle East were observed in Mexico during 2018, resulting in a notable outbreak. This outbreak raised significant concerns among regulators and the agricultural industry, prompting them to prioritize disease awareness. Collaborating with Mexican authorities, the seed industry took proactive measures to address the situation and advocate for preventive actions. As a result, in 2019, Mexico reported no cases of ToBRFV in its agricultural production.

ToBRFV can be easily transmitted through several means, including farming tools and equipment, workers' hands, plants, water, soil, and even people. Consequently, detection methods have evolved over time, becoming more precise and sensitive to accurately identify the virus. Implementing strict hygiene measures during production and incorporating multiple control and inspection processes are crucial preventive measures for containing the virus. These measures play a pivotal role in mitigating the spread of ToBRFV. In response to the virus, tomato and pepper breeding programs are actively working on developing resistance to ToBRFV. These ToBRFV Resistance breeding programs aim to enhance the crops' ability to withstand the virus.

How to help Prevent infection from ToBRFV?

Prevent infection from ToBRFV?

Create awareness of ToBRFV with your employees:

• Educate them in recognizing ToBRFV symptoms (marbling of leaves, discolored fruits, vigor loss in heads)

• Emphasize impact (additional costs,
jobs at risk and increased hygiene measures).

Early detection

Early detection can help to prevent and or limit the spread of the virus. Detection can be done visually as well by taking samples before any symptoms are observed.

Finding, Isolating and Crop Handling of ToBRFV

Early detection is key in preventing spread of the virus. By taking the right measures you can lower ToBRFV pressure and spreading which helps to potentially exterminate it. All employees should be aware of ToBRFV symptoms and should notify the manager when a suspicious plant has been found.

Cleaning after ToBRFV infection

Cleaning and sanitation are critical processes after a ToBRFV infection. ToBRFV is known to be I infectious longer on organic waste attached to surfaces. Drain water and drain water silos have also been found to be contaminated with ToBRFV in infected glasshouses, so ensure proper cleaning of these areas as well.


Where possible avoid combining lit with un-lit crops in one location: making effective cleaning possible by having periods of the year with no plants in the glasshouse.
