Abstract
Summary The preparation Huwa-San TR-50 was used at concentrations of 0.05 and 0.1% to spray plants in a greenhouse after the first visible symptoms of powdery mildew (Sphaerotheca pannosa var. rosae) on roses and of Oidium spp. on cissus plants. After spraying the roses 4 times at 7-day intervals, the percentage rate of effectiveness of Huwa-San TR-50 ranged from 60 to 91% depending on the concentration. In the protection of the Cissus plants, the efficacy of the tested product ranged from 95 to 98%. Increasing the concentration of Huwa-San TR-50 resulted in a significant increase in its effectiveness. In field-grown roses, following the appearance of the symptoms of black spot (Diplocarpon rosae), the shrubs were sprayed with the test product 9 times at 7-day intervals. In results of the assessment carried out after the roses three – fold spraying revealed that the percentage rate of effectiveness of the tested product ranged from 45 to 76% depending on the concentration and the rose variety. After 6 treatments, the efficacy of the preparation Huwa-San TR-50 was lower and ranged from 36 to 47%. And at the final assessment, with increasing severity of the disease symptoms, the effectiveness of the tested product decreased even to 20%. Huwa-San TR-50 was also used to control the rust disease (Puccinia pelargonii-zonalis) in greenhouse-cultivated geraniums. After spraying the plants 4 times, a 3.8–5 times lower number of uredia were found on the leaves of the protected plants in comparison with the control. The spray treatments with Huwa-San TR-50 stimulated the development of the geranium plants.
