The experiment time was optimal for growing tomatoes, so that a low natural infection was expected. Universidad Agraria de la Habana. Seven treatments mycorrhizas, spirulina, ASM, their combinations, and an untreated control were studied to assess the plant enzymatic activity and response to the disease after artificial inoculations of a mixture of A.

The disease control showed by turmeric extracts and curcumin solutions was similar to cupric fungicide, but inferior to azoxystrobin control.

Similar experiments in Australia, but with potato in production greenhouses and a dose of mg a. The presented results show a positive effect of combining seed coating with mycorrhizas and ASM tomage once the plants are established after transplantation.
