Syngenta was the first to announce ToBRFV resistance in late 2020, and the first commercial varieties were planted in early 2021. Since then, we’ve continued to work tirelessly to provide solutions for tomato growers.  

Tomato Brown Rugose Fruit Virus has a significant impact on growers. In fact, growers can lose up to 70% of their produce due to the virus, and it's spreading rapidly. -Ruud Kaagman, Global Crop Unit Head, Tomato

Today we have varieties available with ToBRFV resistance, with many more in development. “Broad resistance will be built in the portfolio during the next several years,” said Ruud Kaagman, Global crop Unit Head for Tomato. 

We will continue studying and discovering new modes of action for resistance against ToBRFV with the big picture in mind. Whether its leaf curl, or ToBRFV, you need a disease package that gives you resistance to all key disease threats – not just the newest one.

“At the end of the day, we need to offer growers good commercial yield with good food quality,” says Stéphane Le Caro, Syngenta Portfolio Lead for Indeterminate Tomato, Passive Greenhouse. “For this reason, we are testing a lot of varieties to find the right fit.” 

The ongoing research aims to expand resistance options and provide some that use different resistance mechanisms. Our researchers are diligent in developing the right ToBRFV resistance that also contains a complete package of resistances and adaptability to suit grower needs – without sacrificing the flavor consumers expect.

“We know our customers need resistance to ToBRFV virus, but also others that can be alone or mixed altogether,” Le Caro explained. “I’m considering especially pepino virus, tomato spot virus, which give symptoms very close to the tobamovirus, so we need to combine all of these in any new variety we deliver.” 

More Resistance Varieties Are In Development

Syngenta currently has the following five varieties with ToBRFV resistance available for commercial use: Lansor, Barosor, Ibeth, Quri, and Waqu.

Our researchers are taking the resistance we currently have on the market and introgressing it into new varieties and new kinds of tomatoes. As these experts continue researching new solutions, they’re committed to a stair-step approach to ToBRFV resistance, with each new mode of action discovered bringing a higher level of resistance than the last. The reason is simple: viruses evolve. 

“We know the virus is changing and it can cause a lot of damage, especially in yield, impacting the plant and changing its behavior,” said Rik Lootens, Syngenta Portfolio Lead for Tomato and Blocky Pepper, Active Greenhouse and High-Tech Production. “Viruses are unpredictable and hard to control. It’s our goal to go as fast as possible to bring new resistances to the market. 

Seventeen additional saladette, cluster, and oval mini varieties are currently in trials with customers in the active and passive greenhouse segments

Keep Your Greenhouse Safe with These Hygiene Standards

It’s incredibly easy to be a transmitter of ToBRFV. It spreads on clothing, footwear, jewelry, and any tool used in infected tomato plants.

By adhering to extreme hygiene rules when visiting any greenhouse or field, growers and visitors can limit the translocation of ToBRFV. Follow these rules to reduce the spread of ToBRFV:

  1. If you’re in an infected area DO NOT go to other greenhouses or fields in the same clothing, shoes, etc.
  2. Upon arrival to greenhouses, use an effective disinfectant on hands, eyeglasses, and shoes and ensure clothing is clean of plant residues.
  3. Avoid visiting multiple greenhouses in one day.
  4. Do not take tomatoes, peppers, or any plant materials from one greenhouse to another.
  5. Avoid bringing jewelry, watches, accessories or phones into greenhouses.
