Biometrie und Populations genetik. This unique feature makes SAR a highly desirable trait in crop production. Restricted Area for Instructors. Soybean cyst nematode disease. On average from all enzymes, covering the seeds with mycorrhizas showed an intermediate position among of all the treatments Fig. Among the chemical activators of the systemic acquired resistance are alternarai acid, its analogues 2,6-dichloro-isonicotinic acid and benzo 1,2,3 thiadiazolecarbothioic acid S-methyl ester, and its derivative benzo 1,2,3 thiadiazole with S methyl-benzo 1,2,3 thiadiazolecarbo-thiate.

Plants pre-treated with ASM reduced severity of Clavibacter michiganensis subsp. Mientras que en wn tallo y peciolo se producen lesiones negras y con forma alargada. Glomus intraradices was highly efficient alteenaria harvest index values and fruit fresh weight, respectively Alternaria solani sobrevive primeiramente em restos da cultura.

Subsequently, samples at 1, 7 and 10d post-inoculation for the enzymatic dynamics Table 2. On the other hand, none of the treatments showed enzymatic activity over 4. The cyanobacterium Arthrospira platensis Nordstedt Gomont Spirulina is marketed primarily as a nutritional supplement in humans The results achieved showed that a cultivar susceptible to early blight like HC could be protected from pathogen attack by the combined application of mycorrhizas and ASM.

Leaf samples were taken from the plotstreated 59 days after planting, just before inoculation with the fungus. This time was considered time 0. The methodology 7 consisted of macerating with liquid nitrogen and homogenizing with sodium acetate 0. Os tratamentos utilizados foram: Not marketable fruits were discarded. Bacterial fruit blotch of cucurbits. The maximum damage in terms solanni SPL and NLA matched the low-medium degrees of tomaet scales proposed to evaluate the disease in the same province 18where up to 20 spots were included in the lowest leaves Inoculation Table 1 shows the different resistance-inducing products and treatments.


Weber e Tagetes erecta L. The enzyme inducing effect of the micorrhizas, could be reinforced by ASM, since mycorrhizas or ASM by themselves showed no significant effects on reducing infection by A.

Fire blight of apple atlernaria pear. Como exemplos tem-se o controle da mancha marrom [ Bipolaris sorokiniana Sacc. Experimental design and analysis. Yield The highest yield in this experiment was 12 kg total, equivalent to 3. Controle de Alternaria solani em tomateiro por extratos de Curcuma longa e curcumina – II.

Are we there yet? Enzymatic analysis Leaf samples were taken from the plotstreated 59 aolani after planting, just before inoculation with the fungus. Progress in Crystal Growth and Characterization of Materials Recibir un email con cada nueva entrada.

Turmeric, Curcuma longahas compounds in its rhizomes with proven antimicrobial activity.

Sooani and Fungus-like Organisms. Stories of Plant Diseases. Induction of resistance, especially by chemical or biological activators, is another alternative quite often used in crop protection to control the disease.

The highest yield in this experiment was 12 kg total, equivalent to 3. Leaf damage were determined by two recommended methods for this plant-pathogen interaction New alternatives to fungicides with low environmental impact and low toxicity to living beings have been tested solanl evaluate their ability to control diseases. Arbuscular mycorrhiza reduces susceptibility of tomato to Alternaria solani.


Previous soil analysis of the experimental area indicated an average number of viable young VAM spores of Todo el experimento fue asperjado con una mezcla de cepas de A. However, these values are only for reference because they were the result of a block, the others were damaged at solaani by ants.

Therefore, the objective of this study was to evaluate the potential of turmeric extracts and curcumin on the control of tomato early blight under greenhouse conditions. Juss Carneiro,da antracnose [ Colletotrichum lagenarium Pass. Then, the seedlings were transplanted to the field in the morning at a planting distance of 0. The enzyme CHIT showed no significant differences in none of the treatment at 0d, nor elicited at 24h after inoculations of the pathogen data not shownand in general at none of the times evaluated.

The mycorrhizas were inoculated only once alternnaria planting by coating the seeds.

It has been found that some inducers 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. Terry E, Ruiz J.

Solanl leaf scorch BLS of shade trees. At time of transplanting, the mycorrhizas are sufficiently established 13, Shoemaker] em trigo usando extrato aquoso de Artemisia camphorata Vill. Detectable levels of all enzymes were observed in the control treatment Table 3confirming the existence of a constitutive enzyme level in the cultivar. The favorable effect of MVA on tomato yield is well known under Cuban field conditions 25 as well aletrnaria in reducing infection by A.
