General use: For outdoor and greenhouse use only. Unless otherwise noted below, the standard application rate for listed species is 1 part Doktor Doom Premium Concentrated Fungicide in 50 (2%) to 200 (0.5%) parts water. Spray all plant surfaces carefully, without exceeding 100 ml of diluted spray per 1 m².
If necessary, repeat sprays every 7 to 10 days unless otherwise noted below. For best control, begin treatment 2 weeks before normal disease onset or when weather forecasts predict a prolonged period of wet weather. You can also start treatment as soon as the disease appears and repeat it at 7-10 day intervals, unless otherwise noted below.
Apply at the highest rate every 7 days or less after heavy rains or when disease extent increases rapidly. For outdoor flowers and ornamental plants, do not exceed 10 applications per year. If possible, schedule applications so that a 12 hour dry time follows application.
Doktor Doom Premium Fungicide Concentrate may cause some copper toxicity on certain plant species. In cases of excessive humidity and cold, leaf spots may appear on cultivated species sensitive to copper. If you are concerned about plant sensitivity, apply to individual plants or small areas of plants and wait to determine if plant damage occurs before treating larger areas.
