Embodiment

[0091] Evaluation of the protective activity of fungicide mixtures against tomato early blight (Alternaria solani; Bayer code: ALTESO):

[0092] Tomato seedlings (Outdoor Girl variety) were grown in soilless media (Metro mix TM ), 1 plant per pot, and used for testing when the first set of leaves were fully expanded. The treated substances consist of econazole, prothioconazole, difenoconazole, azoxystrobin, pyraclostrobin, pyroxystrobin, flufenpyramide, benzovinfluconazole, penthiopyrad, Benbifen, chlorothalonil and zinc manganese Naipur, these compounds are used alone or as a binary mixture with the compound of formula I.

[0093] These compounds were tested as technical grade materials formulated in acetone, and as spray solutions containing 10% acetone and 100 ppm Triton X-100. The fungicide solution was applied to the plants using an automatic compartment sprinkler employing two 6218-1 / 4 JAUPM nozzles set at opposite angles covering the two leaf surfaces at 20 psi ( psi...
