Tomato brown rugose fruit virus In 2015, this deadly virus was detected, and it spreads fast in Israel and Jordan. The abbreviation ToBRFV is used for it. Mechanically - Spread between plants on contaminated tools, clothes or hands. Trade - Seeds you buy are deliberately or unintentionally coated with it. Buy seeds from verified sellers. That I talked about importation of seeds doesnt mean you buy from quacks. Get license to import. Dont smuggle in seeds. I always get this. When people ask me for the prices, they run away. And I do not care. It is why I do not sell seeds. Cos I know majority are looking for quality and cheap. If smuggling will make it cheap they will go for it. But everyone who knows me know I dont do such rubbish. Propagation - Seeds treatment can be infected. Or via cross pollination either by hand or by bees for pollination. No treatment for now. No prevention too. Research is going on, and I am involved in it too. Virus is the new bioweapon. This is going to spread, and new chemicals will be send to you. My Precaution I am an advocate of building strong immume system. This is the clue. This is a principle which works. HIV (it's a virus too) is managed based on this concept. The way antibiotics kill immunity is the way chemicals do. These chemicals are like antibiotics too...and even dangerous. You keep killing immunity using them wrongly. I used to use chemicals wrongly too. Of course, not saying you shouldn't use it at all. But depending on what you do, you use it so you dont kill the immunity of the plant. I cannot teach you. I can only prescribe based on your case the way you visit doctors. Doctors cannot teach you. Goodluck to farmers.
