This suspension was then diluted with water to obtain the desired concentration of active material. Wheat plants (Scipion variety), in seedbeds, sown on a 50/50 peat-pozzolan substrate and maintained at 122 ° C, are treated in the 1-leaf stage (10 cm high), by spraying them with the aqueous suspension described above . The plants, used as controls, are treated with an aqueous solution that does not contain the active material. After 24 hours, the plants were contaminated by spraying them with an aqueous suspension of Mycosphaerella graminicola spores (500,000 spores per ml). The spores are obtained from a 7-day culture. The contaminated wheat plants are incubated for 72 hours at about 18 ° C and 100% relative humidity and then for 21 to 28 days at 90% relative humidity. The classification (% of efficacy) was carried out 21 to 28 days after the contamination, in comparison with the control plants.

The following table summarizes the results obtained when compound 1 and tebuconazole are tested alone and in a mixture in a 1/1 weight ratio.

According to the Coiby method, a synergistic effect of the mixtures tested has been observed. Example 2: Efficacy against Erysiphe graminis f. sp. graminisi of a mixture containing N-. { 2- [3-Chloro-5- (trifluoromethyl) -2-pyridinyl] ethyl} -2-trifluoromethylbenzamide (Compound 1) and protioconazole The tested active ingredients were prepared by crucible homogenization in a mixture of acetone / tween / water. This suspension was then diluted with water to obtain the desired concentration of active material. Wheat plants (Audace variety) in seedbeds, seeded in a 50/50 peat-pozzolana substrate and maintained at 122 ° C, are treated in the 1-leaf stage (10 cm high), by spraying them with the aqueous suspension described above.

The plants, used as controls, are treated with an aqueous solution that does not contain the active material. After 24 hours, the plants were contaminated by sprinkling them with spores of Erysiphe graminis f. sp. tri-tici, being dusted using contaminated plants.
