Protection methods

To control Corynespora cassiicola Long enough crop rotations will be carried out; they will not involve sensitive cultures.

New plantings should be avoided near affected or sensitive crops.
Old diseased leaves will be removed at harvest time; they will in no case be left on the ground.
Fungicides can be applied preventively during periods of risk, or as soon as you notice the very first symptoms. The following active ingredients are reported in the literature for their more or less good performance with regard to C. cassiicola: chlorothalonil, mancozeb, maneb, copper, dichlofluanide, iprodione, etc.

Unlike cucumber, no resistant tomato variety is currently available. However, some lines and cultivars (in Lycopersicon esculentum and L. pimpinellifolium ) have been shown to be very resistant following varietal screening.
