Why the problem requires a two-level?
Viral and viroid infections rapidly reduce photosynthesis, marketability, and yield. Tobamovirus, Potyvirus, Tospovirus, PSTVd, and HSVd are particularly hazardous to solanaceous and cucurbit crops, which is why combining prevention with replication suppression is required.
Cucumber and tomato crops simultaneously face multiple RNA viruses from different genera, necessitating a broad-spectrum agent that maintains its activity even under high viral load.
Why the pathogen's genetic material is the primary target?
Phitoviruses and viroids spread covertly, accumulate rapidly, and reduce crop marketability. Their nucleic acid is the most vulnerable component: viral RNA or DNA, and in the case of viroids, a circular RNA lacking a protein coat.
Why viruses and viroids remain a difficult challenge?
Viruses and viroids in tomatoes and other vegetable crops are poorly controlled by standard treatment schemes. For both greenhouse and open-field environments, solutions effective against mixed infections are especially important.
