“…The components with phenolic structures, like carvacrol, eugenol, and thymol, are highly active against pathogens. Obtained findings are in agreement with Karavaev et al (2002) who reported that the aqueous extracts from bird cherry tree Padus avium, aspen Populus tremula, and celandine Chelidonium majus effectively suppressed the P. triticina and antifungal activity was attributed to the high content of phenolic compounds in the leaves of these plants.…”

Five plant extracts, i.e., henna, Lawsonia inermis; acalypha, Acalypha wilkesiana; chinaberry, Melia azedarach; pomegranate, Punica granatum; and lantana, Lantana camara, were tested as inducers to protect wheat against leaf rust infection caused by Puccinia triticina Eriks. The plant extracts were applied pre-infection on susceptible wheat cultivar "Gemmiza-7" under field conditions during two growing seasons (2016/2017 and 2017/2018). All the tested plant extracts were found to be effective against the leaf rust infection. They significantly reduced the coefficient of infection (ACI) to be ranging 7.50 to 20.00, compared to the non-treated control (ACI = 75.00). Lantana extract was the most effective one (efficiency = 88.88%), which was very close to the fungicide "diniconazole" (efficiency = 89.92%). Henna extract ranked second (80.00%), followed by chinaberry (76.00%), acalypha (72.00%), and pomegranate (68.00%). However, wheat yield components were significantly increased by all the tested treatments, especially lantana extract and the fungicide. Similarly, biochemical analyses revealed a significant increase in the plant contents of chlorophyll a and b, total phenolics, and oxidative enzymes activities (POX and PPO) at all the tested treatments. Results indicated that the tested plant extracts could induce wheat resistance to leaf rust.

Rust fungi are devastating plant pathogens, and several Puccinia species have exerting substantial financial impacts on global barley cultivation. Fungicides are used on a large scale as an effective method for combating phytopathogenic fungi. The negative environmental impacts of fungicides are steadily escalating on a daily basis. Consequently, researchers are currently exploring alternative approaches to mitigate the use of fungicides, such as the utilization of plant extracts. This method has proven effective due to its incorporation of natural antifungal substances. Among the nine natural elicitors that were tested, the application of plant extracts on barley seedlings resulted in an increase in the incubation and latent periods of Puccinia hordei. These periods are integral components of partial and induced resistance, effectively mitigating the incidence of barley leaf rust disease by over 70% on mature plants. Similarly, the biochemical analyses demonstrated a notable augmentation in all the tested treatments’ overall phenolics and oxidative enzyme activities (peroxidase and polyphenol oxidase). Random amplified polymorphic DNA (SCoT) test serves as a viable approach for assessing the impact of plant extracts and microorganisms on barley plants. The results obtained from this study indicate that the detection of DNA polymorphism through SCoT analysis holds a significant potential powerful tool to evaluate genetic changes compared with untreated plants although some of them tested displayed high similarities at the morphological reaction.

Soybean (Glycine max (L.) merr.) is a well-known leguminous crop serving as a principal protein rich food source for human and livestock. The study examined the antifungal efficacy of sodium bicarbonate (NaHCO 3) and Carica papaya on fungi isolated from soybean seeds. The inhibitory effects of sodium bicarbonate (NaHCO 3) and leaf extracts of Carica papaya were tested on three fungi. In vitro studies were carried out on Potato Dextrose Agar (PDA) for fungal isolation from soybean seeds and for the control of the pathogens using NaHCO 3 and C. papaya. The results obtained were compared with benlate (a.i 50% Benomyl); a synthetic fungicide. Aspergillus niger had the highest percent occurrence (50%) followed by F. ventricosum (33%) and then B. theobromae (17%). The percent fungal inhibition was highly significant at 1% level of probability, indicating that all the antifungal agents exhibited broad spectrum inhibition against the isolates. Benlate completely (100%) inhibited the three pathogens. There was no significant difference (P ≤ 0.05) in the inhibition of A. niger at 1.54 mg/ml of C. papaya and 3 mg/ml of NaHCO 3. Fusarium ventricosum and B. theobromae were best inhibited at 1.54 mg/ml of C. papaya with mean values of 95.63% and 95% respectively. A positive and significant correlation occurred between the inhibitions of all the fungal isolates. This implies that all the antifungal agents are capable of inhibiting the three fungal isolates. The study suggests that C. papaya and NaHCO 3 are capable of controlling seed-borne pathogens in soybean seeds.
