Fig. 1. Hymenium formation of Thanatephorus cucumeris anastomosis subgroup 3-TB (AG-3-TB) strains on the different host crops and the surface soil near tomato stems.

Findings from Minghuan Wang et al. indicate that host plant species, strain differences, urea, and fungistatic stress significantly influence #Thanatephorus cucumeris sporulation, revealing the pivotal role of spore production in the disease development: https://doi.org/10.1094/PHYTO-02-25-0086-R
