Though specific data about seed as a pathway for race 3 in nature has not been found, other races of the pathogen are known to be seed-borne. Seed as a pathway for race 3 seems to be accepted by the industry.

Blotter Incubation
Commercial testing is available but methods have not been validated and standardized. The blotter method can not distinguish between races and requires pathogenicity tests on tomato varieties with resistance to races 1 and 2.

Fungicides
References specific to race 3 were not found, however, a seed treatment (such as Thiram slurry), used as a prophylactic measure, may be effective against the fungus.
