“…Also, they indicated that 1.0% for sodium benzoate showed high radial growth reduction by 63.3% and 61.1%, respectively, compared to the untreated control. Such results are in harmony with those reported by (Menzel et al, 2016 andBarakat andAl-Masri, 2017).…”

“…It is an excellent source of vitamin C, which contains an average 40-90 mg. Egypt is considered the third largest producer of strawberry in the world after the United States and Spain (Wu et al, 2012). In Egypt, strawberry is one of the most important vegetable crops for local consumption and exportation (Embaby et al, 2016, andBarakat andAl-Masri, 2017). Unfortunately, strawberry is affected by several plant diseases that affect its yield and quality in both the pre-and post-harvest stages.…”

Effect of two fungicides (i.e. iprodione and cyprodinil+flydioxonil mixture) and two salts (sodium bicarbonate, SBC, and sodium benzoate, SBO) were evaluated separately or in mixtures in laboratory experiments as well as under field conditions against Botrytis cinerea instant of the fruit gray mould of strawberry. All tested salts and fungicides as well as their mixtures significantly decreased the radial growth of B. cinerea in vitro. Complete inhibition of radial growth was obtained with SBC at 2.0 and1.0 g/100ml. Also, high reductions were obtained with SBC at lower concentrations. The fungicide iprodione at 500 mg/L completely inhibited radial growth of B. cinerea, while complete inhibition was obtained with cyprodinil+flydioxonil at lower concentration (10 mg/L). Mixing the tested fungicides with salts increased their inhibition effect on B. cinerea growth at lower fungicide concentrations. iprodione at 0.1 mg/L mixed with SBO at 1g/100ml completely inhibited radial growth. Also, cyprodinil+flydioxonil at 0.1mg/L mixed with SBC at 0.2 g/100ml completely inhibited radial growth of B. cinerea while 0.001mg/L cyprodinil+flydioxonil fungicide with SBO at 2.0g/100 completely inhibited radial growth. On the other hand, the field experiments showed that all treatments with the tested salts and fungicides significantly decreased postharvest Botrytis gray mould on fruits harvested 1, 3, 7, 10 and 15 days after treatments and stored at 5˚C for seven days. However, the treatment with 50% cyprodinil+flydioxonil + SBC 2% was the most effective and decreased mean percentage of infection to 4% compared to 23.86 % for the untreated control. This was followed by 50% iprodione +SBC 2%, 25% iprodione + SBC and 25% cyprodinil+flydioxonil + SBC 2%, and cyprodinil+flydioxonil, alone, and iprodione, alone, with percentages of infection being 7%, 8%, 8.5%, 8.5%, and 9%, respectively, while (SBC 2%, alone) treatment showed the least effect with 12.93 percentage of infection. Meanwhile, positive strong correlations (r = 0.981 to 0.943) were revealed between Infection (%) and harvest interval periods with two salts mixed with iprodione and cyprodinil + flydioxonil after stored at 5˚C. Also, the enzyme assay revealed that increases in the activity levels of pectolytic and cellulytic enzymes produced by the fungus were associated with high fruit rots incited by B. cinerea. Meanwhile, residues of all tested fungicides in treated strawberry fruits decreased with decreasing fungicide concentrations in the salt + fungicide mixtures. cyprodinil (25%) + SBO, and cyprodinil (25%) + SBC treatments exhibited the lowest residue values being 1.420, and 1.680 mg/kg fruit one hour after treatment while the other treatments showed higher residue values while the highest was recorded for iprodion at recommend dose being 29.81 mg/kg fruit. However, fungicide residues decreased with increasing time after preharvest treatments.

“…A similar combination with a 10-fold reduction of the fungicide dithianon was more effective in controlling scab (caused by Venturia inaequalis) than the fungicide alone at the recommended dose in field trials of apple [56]. Moreover, plant extracts of Inula viscosa combined with the fungicide iprodione at a reduced rate were as effective against B. cinerea on bean plants as the full dose of fungicide [57].…”

Combining Biocontrol Agents with Chemical Fungicides for Integrated Plant Fungal Disease Control

et al. 2020

Feeding a rising population of currently 7.8 billion people globally requires efficient agriculture, which is preferably sustainable. Today, farmers are largely dependent on synthetic fungicides to avoid food losses caused by fungal diseases. However, the extensive use of these has resulted in the emergence of fungicide-resistant pathogens and concerns have been raised over the residual effects on the environment and human health. In this regard, biocontrol agents (BCAs) have been proposed as an alternative to standard fungicides but their disease management capacity is usually incomplete and heavily relies on uncontrollable environmental conditions. An integrated approach combining BCAs with fungicides, which is the focus of this review, is put forward as a way to reduce the fungicide doses to manage plant diseases and thereby their residue on harvested crops. In addition, such a strategy of combining antifungal treatments with different modes of action reduces the selection pressure on pathogens and thereby the chances of resistance development. However, to allow its large-scale implementation, further knowledge is needed, comprising timing, number and interval of repeated BCA applications and their compatibility with fungicides. The compatibility of BCAs with fungicides might differ when applied in a mixture or when used in alternation.

Synthesis of new pyrazolone and pyrazole-based adamantyl chalcones and antimicrobial activity

et al. 2020

View full text Add to dashboard Cite

Chalcones and their derivatives are becoming increasingly popular due to their various pharmacological effects. Chalcone molecules may be extracted from natural resources, entirely synthesised, or biosynthesised by modifying the natural ones. In this study, five pyrazole based adamantyl heterocyclic compounds were synthesised by condensation of 1-adamantyl chalcone with substituted phenylhydrazine. The products were characterised by using ¹HNMR, ¹³CNMR and FT-IR spectroscopy. The microbiological activity of these compounds was investigated against bacteria and fungi. The new compounds showed good to moderate activity against the microbial species used for screening. All developed molecules showed antibacterial activity against gram-negative and gram-positive. These molecules showed antifungal activities against Fusarium oxysporum fungus and in a dose-dependent manner, apart from RS-1 molecules which showed compromised antifungal activity and even at a high dose.
