In practice, different methods of application of a phytosanitary product as well alternzria the times and frequency of application determine the crop’s response to disease 8.

Early blight of potato and tomato (Pinta-preta {Alternariose} da batata e tomate – Português)

Field Control of Bacterial Spot and Bacterial speck of tomato using a plant activator. Subsequently, the mycelium of each isolate was vacuum filtered through filter paper Whatman 1weighed and proportionally fragmented into blender for min. Topics in Plant Pathology.

After d of pathogen inoculation, the necrotic leaf area NLAnumber of spots per leaf SPL and yield were determined. The methodology 7 consisted of macerating with liquid nitrogen and homogenizing with sodium acetate 0. Pinta-preta Alternariose da batata e tomate. Plant Disease Mngmt Simulations.

The results solanii here suggest that enhancement of natural resistance of tomato cultivars will help to reduce the number of fungicide applications even if they are susceptible to early blight.


The lowest percentage of NLA was achieved in the combination of ASM-mycorrhizas, while the spirulina treatment was the most affected Fig.

At 59 d post-transplant, all treatments were inoculated with a mixture of four Cuban pathogenic isolates of A. Comparing the effects of the treatments at 10d, the ASM-mycorrhiza combination induced significantly higher level of enzymes than the worst treatments control and spirulina-mycorrhizas.

The increase in enzyme activity and protection against the pathogen were minimal in the spirulina and control treatments. In fact, ASM-mycorrhizas was the only treatment that markedly but not significantly differed from five of the total seven treatments, considering the NLA.

The overall average was Activation of induced resistance by means of the six enzymes included in this study can also protect the crop from other pathogens. Carretera de Jamaica y Autopista Nacional. Leaf damage were determined by two recommended methods for this plant-pathogen interaction Untreated plants showed low otmate levels, but not necessarily lower levels of pathogen infection.

Biology, Epidemiology and Pathogenicity. Ten days after inoculations with A. Contact Us – Report a Bad Link. This ej feature makes SAR a highly desirable trait in crop production.


En las hojas se generan manchas circulares o angulares que a veces presentan un halo amarillo. These methods can be described briefly as follows. Zonificacion de Alternaria solani en papa en la provincia 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 reaction rate of oxidation was determined by recording the product absorbance at alternarua. Detectable levels of all enzymes were observed in the control treatment Table altrrnariaconfirming the existence of a constitutive enzyme level in the cultivar.

It remains to determine the response of tomato under more favorable conditions for the alternaroa infection, such as planting outside the optimum growing season, where temperatures favor the epidemic, or in areas with high rates of infection. Induction of defence-related enzymes and resistance by the plant activator acibenzolar-S-methyl in tomato seedlings against bacterial canker caused by Clavibacter michiganensis ssp. Control of Alternaria solani in tomato by Curcuma longa extracts and curcumin – II.

Alternaaria were sown in a dry heat sterilized mix of ferralitic red soil and peat contained in plastic trays.
