Background and Objective: Soybeans are a globally important crop consumed by both man and animal. Worldwide production in 2019/2020 was 358 million metric t. The current research aimed at testing the possible correlation between treating seeds and plants of soybean with antioxidants and retreading the disease severity that occurred by the pathogeni...

Uses of a green chemistry in form of antioxidants and micronutrients for seed treatments or for foliar spray on faba bean plants was implemented as a delicate tactic for controlling chocolate spot disease cause by Botrytis fabae. The in vitro trials revealed that salicylic acid at 7 mM inhibited the growth of B. fabae followed by zinc at 8 g L-1 an...

Laboratory and greenhouse experiments were conducted to study the role of some vitamins in decrease of seed deterioration of soybean (Glycine max L. Merrill) during storage and enhance seedling vigor. Seeds stored in cotton bags for 0, 2, 4 and 6 month periods after sprayed with Vitamin C (50, 75 and 100 ppm), Vitamin B9 (10, 15 and 20 ppm) and Vit...

This study was carried out for two successive seasons 2011 and 2012 in order to evaluate the efficiency dipping of Le Gonte pear fruits in sodium bicarbonate (SBC) and/or potassium sorbate (KS) either alone or in combination to maintain fruit quality and control postharvest diseases at cold storage or during marketing at room temperature. Pear frui...

The fungi play an important role in cheese manufacture such as Penicillium roqueforti nevertheless subsequent development of filamentous fungi occurs during cheese ripening on its surface, this accompanied with production of some bad flavors and tastes, as well as some mycotoxins. In this study, 125 samples of cheeses were collected to determinatio...

This study intended to revise the effect of postharvest dipping in boric acid and/or jojoba oil alone on quality of Washington Navel orange fruits through marketing period at 18°C. The experiments were carried out during 2011 and 2012 seasons. Results showed that all dipping treatments of orange increased fruit quality when compared with the contro...

Pesticides can pose risks and technological problems of dairy products if used improperly or frequently. The present work aims to investigate the effect of two fungicides (Anadol and Tasolen), herbicides (Round up and Saturn) and insecticides (Lannate and Reldan) commonly used in Egypt on certain lactic acid bacteria (Streptococcus salivarius subsp...

The causal pathogens of root rot and stalk rot of soybean were isolated from infected plants. Fusarium oxysporum, F. solani, Macrophomina phaseolina and Rhizoctonia solani were the main causal pathogens of pre- and post-emergence damping-off The isolated fungi especially R. solani caused anatomically deformation in the basal portion of infected ste...

... Findings showed that extracts from all natural sources had a positive outcome in reducing pathogen extension when compared to uncovered pathogens. Totally of the extract were able to keep the berries postharvest quality without affecting quality metrics like TSS, total acidity, or total sugar% [11] . ...
... R. solani is proved to be one of the most dominate pathogenic fungi to lupine plants causing root rot symptoms. Some chemicals are effective in controlling plant diseases but they are expensive and not environmentally friendly, therefore, alternative control methods are needed (Abd El-Hai et al., 2016). ...
... As a result, it has produced the maximum numbers of tillers per plant. The same result was reported by different researchers that salicylic acid inhibits the seed germination and seedling growth of faba bean (Elwakil et al., 2016;Lv et al., 2020). The rate of seed germination inhibition increases with increasing concentration of salicylic acid (Elwakil et al., 2016). ...
... In addition to temperature and humidity management, chemical strategies can also be employed to avoid the depression of the protective capacity of the seed against ROS, such as the use of vitamins (El-Metwally et al., 2014) or the use of sodium hydrosulfide (NaHS) (Li et al., 2013) in the treatment of seeds. Vitamins C (ascorbic acid) and E (tocopherols and tocotrienols), for instance, act as antioxidant compounds, preventing the damage caused by the ROS (Xia et al., 2015). ...
... Similar results were also reported by Montagna et al. [72] and Embaby et al. [73] who stated that all examined buffalo milk cheese samples were consistently negative for AFB 1 . In contrast, positive results were recorded by Abou Ayana et al. [74] and Mao et al. [75]. ...
... Flame seedless with K 2 Si 2 O 5 at 250 ppm increased weight of berry and cluster over control. Spraying potassium silicate increased the fruit firmness in "Amal" apricot cultivar 103 , "Anna" apple 104 and orange 105 as compared to untreated trees. Additionally, the exogenous sprinkle of K 2 Si 2 O 5 on banana cv. ...
... The mechanism of BTHWA involves the activation of the genes coding PR proteins and other proteins engaged in induction of resistance (PAL and NPR1). One of the effects of induced resistance is increased content of phenolic compounds [53], anthocyanins [54] and antioxidants [55], which has been also established in our studies concerning the impact of the BTHWA treatment. We found a direct correlation between the content of these substances in the strawberry fruits and the presence of Phytophthora sp. and Colletotrichum sp. ...
... This was because different banana varieties would have different level of susceptibility towards phytopathogenic fungi (De Costa and Chandima, 2014). Other researcher also found that NaHCO 3 effects were less consistent for its ability to control fungi when applied alone (El-Eryan and El-Metwally, 2014). The efficacy of NaHCO 3 of the same concentration probably exerts different effect on anthracnose disease development of different banana varieties. ...
... As shown in Table 3, the diazinon reduction percent by probiotic bacteria in samples containing 5000 μg/L of spiked diazinon (A-9-5) was lower than those containing 1000 μg/L of diazinon (A-9-1) which were 57.53 and 23.63 % which is in good agreement with Đorđević et al. (2013a) and Yousefi et al. (2019) studies. In fact, the presence of diazinon could be effective in probiotic viability and activity (acid and other compounds' production) which was also confirmed by Ayana et al. (2011) in a study done in yogurt in the presence of some pesticides. Đorđević et al. (2013a) also reported that pirimiphos-methyl (a pesticide) could just inhibit the growth of L. plantarum in concentrations higher than 5 mg/kg during wheat fermentation. ...
... Among nanoforms of 15 micronutrients, CuSO 4 and Na 2 B 4 O 7 were found most effective in controlling rust disease of field peas [37] . Microelements such as manganese and zinc also suppressed the damping off and charcoal rot diseases in sunflower [38] . The Ag NPs/PVP were tested for fungicidal activity against different yeasts and molds such as Candida albicans, C. krusei, C. tropicalis, C. glabrata and Aspergillus brasiliensis. ...
