Experiments have been carried out to assess the possibility of the destruction by composting of mycelium of Didymella lycopersici in diseased tomato haulms. The results of laboratory trials with agar cultures and with infested tomato stems and fruits suggest that the fungus is destroyed if kept under moist conditions at 35° C. for from 3 to 6 days. Agar cultures buried for approximately this length of time in composting material at this or higher temperatures were dead when recovered. When composts made from haulms of tomatoes affected by Didymella stem rot were tested by placing them round the stem bases of tomato plants, or by growing tomato plants in them, few of the test plants became diseased. It was concluded that D. lycopersici present in tomato refuse could be destroyed by careful composting.
