In the case of diseases of the foliage of the drug (100 PM to 1 million of active ingredient) was sprayed on the leaves, and were introduced to the plant roots in the soil. Sprays were applied to the maximum retention on the surface, and the roots were moist to a final concentration equivalent to approximately 40 hours to obtain a final concentration of 0.05%.

In the case of most of the test compound was applied to the soil (roots) and the leaves (spraying) for one or two days before infection of a plant disease. The exception was the test against Erysiphe graminis, in which the plants were inoculators for 24 h before processing. Deciduous pathogens were applied by spraying suspensions of spores on the leaves, used plants. After inoculation the plants were placed in a suitable environment to enable development of the disease, and then were incubated up until inoculation was not ready for evaluation. The period between inoculation and evaluation varied from 4 to 14 days, depending on disease and environmental conditions.
