“…This was demonstrated by the percentage of surviving callus up to 100% in subculture I and II. This finding was in according to result in Abo-Elyousr et al (2009) experiment, salicylic acid was a non-toxic compound and could be applied to plants for controlling pathogen infection.…”

“…Salicylic acid compound as the inducer agent of defense could increase the synthesis of peroxide (PO) and polyphenol oxidase (PPO) enzymes. Both of these enzymes associated with the induction of plant resistance against pathogens and some plant defense mechanisms, such as biosynthesis of lignin and other oxidative phenol (Bestwick et al, 1998;Abo-Elyousr et al, 2009;Dihazi et al, 2011). Fusaric acid was a compound produced by the genus Fusarium oxysporum which were toxic at a certain concentration.…”

Fusarium wilt caused by Fusarium oxysporum f.sp.cepae (Foc) is one of the most important diseases of onion in Indonesia. Induced resistance was one of the effective techniques to acquire resistance to fusarium wilt in shallot. Salicylic acid (SA) had been inferred to be in endogenous signal in the systemic acquired resistance response of plants. This research aimed to study the effect of exogenously added SA to resistance in shallot callus cv. 'Bima Brebes' to fusarium wilt disease in vitro; and to determine the effective concentration of SA to induce resistance. A group of shallot callus was grown in MS medium containing varying SA concentration (0, 15, 20 and 25 ppm) in vitro for 2 weeks. Then, the callus were treated with toxin of Fusarium oxysporum, namely fusaric acid, to have observe the resistance response. In vitro selection was done twice in different fusaric acid concentration. Application of exogenous SA at all concentration did not suppres time of appearance of disease symptom yet. Toxic symptom in the callus was shown by the browning or blackening (off) of callus. Salicylic acid at concentration of 20 ppm effectively reduced the toxic symptom up to 16.66% and supported callus regeneration better than the concentration of 15 ppm and 25 ppm. The number of resistant callus regenerated was 66.67% at pretreatment of 20 ppm of SA.

“…The maximum level of PPO activity was 10.7 enzyme unit mg -1 protein min -1 and was recorded at the 3 rd day from the SA or water application. Abo-elyousr et al (2009) reported that PPO activities increased in SA pre-treated onion plants inoculated with S. vesicarium and PPO activities remained at higher levels throughout the experimental period. Tomato plants treated with ASM and inoculated after 3 days with Clavibacter mimichiganensis subsp michiganensis showed higher peroxidase activities than other treatments (Baysal et al, 2003).…”

Tomato bacterial spot caused by Xanthomonas vesicatoria is an important disease in many tomato production areas in the world. The potentiality of salicylic acid (SA) to suppressing bacterial spot of tomato (Lycopersicon esculentum L. var.) under artificial inoculation conditions was investigated in the current work. Tomato plants cv. Super Strain B were sprayed with SA (10 mM) and inoculated with a virulent X. vesicatoria strain for four days post spraying. SA significantly reduced bacterial leaf spot severity, number of lesions per leaf and spot diameter in tomato plants pre-treated with SA compared with the untreated control plants. Changes in the activities of peroxidase, catalaze and polyphenol oxidase in tomato plants after application by SA and inoculation with X. vesicatoria were studied. In SA-treated leaves (plants), an increase in enzymes activities was observed five days after challenge inoculation with X. vesicatoria. The expression of resistance induced by SA was evidenced by the increase in peroxidase (POX) and polyphenol oxidase (PPO) activities, starting from the first day after spraying. These results indicated that the future integrated disease management programs against tomato bacterial spot may be enhanced by including foliar spray of SA.

“…Certain chemicals, such as salicylic acid (SA), 2,6-dichloroisonicotinic acid (INA), potassium salts, amino butyric acid (BABA) and benzo (1,2, 3) thiadiazole-7-carbothioic acid S-methyl ester (BTH) were reported to induce SAR in plants against some plant pathogens (Reuveni et al 2000;Oostendorp et al 2001;Lin et al 2009). Also, Abo-Elyousr et al (2009) found that onion plants sprayed with 20 mM SA can significantly reduce the severity of Stemphylium leaf blight of onion.…”

The efficiency of some commercial biological control agents (BCAs), Bio Zaid and Bio Arc, and resistance inducers chemicals (RICs) (salicylic acid and Bion) on management of cucumber powdery mildew, caused by Sphaerotheca fuliginea, was evaluated in vitro and in vivo. In vitro experiments revealed that application of the tested BCAs and RICs significantly reduced the disease severity, number of conidia per leaf area unit (cm) and reduced germination of conidiospores of the causal pathogen. Under field conditions, application of BCAs and RICs caused significant decrement in the disease severity with significant increment in the fruit yield compared with check treatments. On the average, application of Bion recorded the highest values, either in reducing the disease severity or in raising the average fruit yield followed by Bio Arc. On the other hand, applying salicylic acid (SA) recorded, on the average, the lowest efficiency in reducing disease severity and low values of fruit yield in both growing seasons.
