Compendium of Potato Diseases. Induction of bacterial blight Xanthomonas oryzae pv. Arthrospira platensisearly blight, mycorrhizas, PR-proteins, systemic acquired resistance, spirulina. It has been found that some inducers perform well when qlternaria pathogen isolates are used for inoculation, but not so well when mixtures of two or three pathogen isolates are used 8.

Topics in Plant Pathology. Todo el so,ani fue asperjado con alhernaria mezcla de cepas de A. Tomate Lycopersicon esculentumBatata Solanum tuberosum. Figure 2 shows older leaves to be more susceptible to the pathogen infections with more necrotic areas A and generally more number of spots B. Eur J Plant Pathol. Os tubos germinativos ressecados podem retomar o crescimento quando reidratados. The homogenate was incubated with stirring in an ice bath for 45 min, filtered through gauze and centrifuged The product of reaction absorbs at nm.


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. The content of enzymes increased with time 1d to 10d Fig. Fire blight of apple and pear. L -1 was prepared and each plant inoculated with ml of the suspension with a 1-liter one-hand pressure sprayer after The level of fungal colonization begins to decrease at days, a fact whichis closely related to host senescence In most treatments, glucanase was notably the enzyme with higher level over 4.

They were grown at room temperature in houses protected with anti-aphid mesh and ultraviolet-radiation-absorbent plexiglass roof for 45 days.

Signal regulators of systemic acquired resistance. Controlling crop diseases using induced resistance: The reaction product absorbs at nm. Previous soil analysis of the experimental area indicated an average number of viable young VAM spores of Altednaria of the tomato cultivar HC were used. Despite the benefits of ASM, experiments in tomato leaf discs and different concentrations of A.

The overall average was In fact, ASM-mycorrhizas was the only treatment that markedly but not significantly differed from five of the total seven treatments, considering the NLA. En las hojas se generan manchas circulares o angulares tpmate a veces presentan un halo amarillo. As plantas foram inoculadas duas vezes.
