If it is a viral disease, the symptoms of the heart lobe should be more pronounced. The seedlings seen here only have a few abnormal leaves in the upper and middle parts, while the symptoms of the heart leaves are not obvious, not much like viral diseases.If the tomato fruit has a large navel, 2.4-D drug damage can also cause such symptoms.
