Utilizaram-se as quatro linhas centrais para o ensaio, deixando-se duas linhas de bordadura.

Principales plagas y enfermedades del tomate

Efecto de extractos vegetales en la germinacion de esporas y en los niveles de dano de Alternaria solani en tomate. It has been found that some alternarria perform well when single pathogen isolates are used for inoculation, but not so well when mixtures of two or three pathogen isolates are used 8. The objective of the research was to measure the protection by chemical and biological resistance activators to the damage of A. The disease control showed by turmeric extracts and curcumin solutions was similar to cupric fungicide, but inferior to azoxystrobin control.

Se estudiaron siete tratamientos: This suggests algernaria the treatments where ASM was included also tended to have more necrotic areas on the leaf, the second principal component increased with increasing yield. Due to the presence of exopolysaccharides in its cultures, it is expected that there is a positive effect on the defense system of plants. Experimental design and analysis. Only in ASM-spirulina and spirulina-mycorrhizas treatments, the differences were significant Fig.


On the other hand, none of the treatments showed enzymatic activity over 4.

Lethal yellowing of palm. The reaction rate of oxidation was determined by recording the product absorbance at nm.

Soybean cyst nematode disease. This cultivar is susceptible to early blight and low inducing pathogenesis-related proteins PR proteins against A. Brazilian Arch Biol Technol. Em um estudo sobre o efeito de C. Fire blight of apple and pear. Los pulgones tienen enemigos naturales que ayudan a su control como Chrysoperla carnea o Chrysopa formosa. Transcriptome profile of acibenzolar-S-methyl-induced genes in tomato suggests a complex polygenic effect on resistance to Phytophthora infestans.

Recibir un email con los siguientes comentarios a esta entrada. Como exemplos tem-se o controle da mancha marrom [ Bipolaris sorokiniana Sacc. BoxGuayaquil, Ecuador. It should be pointed out that there were a low level of mycorrhizas in the field blocks 22between young viable spores data not shown.

Mientras que en el tallo y peciolo se producen lesiones negras y con forma alargada. Permalink Gallery DD Inyectable, fumigante del suelo.

These results show the potential of turmeric and curcumin for the control of tomato early blight. Signal regulators of systemic acquired resistance. Effects of inoculum concentration, wetness duration and plant age on development of early blight Alternaria solani and on shedding of leaves in tomato plants.

Are we there yet? Vloutoglou, I and S. Eur J Plant Pathol. The treatments with spirulina-mycorrhizas, spirulina alone, and the control not treated showed the lowest level of all the enzymes analyzed Fig. Antifungal and insect-repellent activities of essential oil of turmeric Curcuma longa L.

  ASTM D1415 PDF

No significant differences among treatments were observed with ASM-mycorrhizas, although more damage was observed in all the treatments with spirulina Fig. Inoculation Table 1 shows the different resistance-inducing products and treatments.

En las hojas se generan manchas circulares o angulares que a veces presentan un halo amarillo.

Plagas y enfermedades del tomate

Universidade Federal de Lavras. The increase in enzyme activity and protection against the pathogen were minimal in the spirulina and control treatments. Na literatura foi encontrado apenas um relato sobre o controle de A. Experimental design and analysis A random alternaroa design with three replications and seven treatments per block was used. Yield The highest yield in this experiment was 12 kg total, equivalent to 3. By themselves, mycorrhizas and ASM showed no noticeable effects in reducing infection by A.


Similarly, different isolates produce different biochemical responses depending on the cultivar At 12 days post-inoculation, the percentage of necrotic area per leaf NLA a,ternaria determined in all plants by visual assessment by two evaluators see time line in Table 2. The experiment time was optimal for growing tomatoes, so that a low natural infection was expected.

The reaction product, cinnamic acid, absorbs at alternxria, and the reaction rate was determined with its readings.

The level of fungal colonization begins to decrease at days, a fact whichis closely related to host senescence Biology, Epidemiology and Pathogenicity.
