In two consecutive trials, three treatments of tomato plants of the variety Rivermoon with the antiphytoviral substance DHT (2,4‐dioxohexahydro‐1,3,5‐triazine, 0.15%) 2 d a.i. and 2 and 7 d p.i. reduced the concentration of ToMV (tomato mosaic virus) by 62.3 and 60.5%. The average tomato yields increased by 40 and 26 % compared with the virus diseased, untreated controls, but the yields of the healthy controls were not achieved. A combined treatment of DHT, alkane monosulphonate and N‐phenyl‐N'‐p‐carboxyphenyl thiourea only resulted in a minor reduction in the ToMV titre and only a slight increase in yield, compared with the DHT‐solo treatment.
