“…The highest inhibitory effect (69.9% inhibition) was exhibited at 0.2 AA + 4.0 H 2 O 2 g/L while using 0.1 AA + 4.0 H 2 O 2 g/L expressed 51.9%inhibition that showed insignificant effect with using 0.2 AA + 2.0 H 2 O 2 g/L which explored 48.9% inhibition. Antifungal effects for PAA which resulted from mixed AA + H 2 O 2 (Buschmann and Del Negro, 2012) were confirmed against several phytopathogenic fungi ((Mari et al, 2004;Feliziani et al, 2016;Ayoub et al, 2017 andEl-Ashmony et al, 2017).…”

“…It was reported that severe smut outbreak in the Caribbean has created an impact amongst cane growers and sugar industry. Consequently, the plantations are undertaking different smut management practices such as continued monitoring and rouging of smut affected stools, hot water treatment (at 50°C for 2 hours for initial seed cane nursery) of seed sets, chemical treatment of sets, use of resistant varieties, and avoidance of ratooning of affected fields (Abdou et al, 1990;Wada et al, 1999;Abera et al, 2009;Firehunet al, 2009;Mansour et al, 2016;Carvalho et al, 2016;Sánchez-Elordi et al, 2016 andLiu et al, 2017) Due to their core role in plant health, reactive oxygen species (ROS) and antioxidants Sutherland (1991) and Levine et al (1994) have shown a major role in plant pathogen interactions (Galal and Abdou, 1996;Adam et al, 2000;EL-Ashmony et al, 2017). Both acetic acid and hydrogen peroxide reacted as bactericides and fungicides against many phytopathogenic bacteria and fungi (Narcisoet al, 2007 andOsórioet al, 2013;Ayoub et al, 2017 and).…”

n eco-friendly agent, hydrogen peroxide (H 2 O 2)-based compound, peroxyacetic acid (PAA) gave efficiency against Sporisorium scitamineum teliospore viability. A significant sporocidal effects for all AA + H 2 O 2 combinations tested against S. scitamineum teliospores germination was explored. The highest inhibitory effect (69.9% inhibition) was exhibited at 0.2 AA + 4.0 H 2 O 2 g/L followed by 0.1 AA + 4.0 H 2 O 2 g/L (51.9% inhibition) and 0.2 AA + 2.0 H 2 O 2 g/L (48.9% inhibition). Under field experiments, most of AA + H 2 O 2 treatments were reduced smut disease incidence (SDI) significantly. However, SDI values showed insignificant variances among four treatments, 0.1 AA + 1.0 H 2 O 2 g/L, 0.1 AA + 2.0 H 2 O 2 g/L, 0.1 AA + 4.0 H 2 O 2 g/L and 0.2 AA + 1.0 H 2 O 2 g/L, in two planting dates. While the two treatments, viz. 0.2 AA + 2.0 H 2 O 2 g/L and 0.2 AA + 4.0 H 2 O 2 g/L, showed significant variances values in SDI as they significantly reduced SDI values in May more than in October. Meantime, means of protection values (MPV) of 0.2 AA + 2.0 H 2 O 2 g/L and 0.2 AA + 4.0 H 2 O 2 g/L, showed significant variances in MPV values as they were significantly raised in May being 86.55% MPV more than in October, 70.85% MPV. In May planting date, MPV was significantly higher than in October planting date particularly in the check plants.

T HIS STUDY aimed to examine the biofumigation effect of cabbage, broccoli and cauliflower against Sclerotinia sclerotiorum (Lib.), the pivotal agent of white rot in eggplant under in vitro conditions. Also, field experiments were carried out to assess the effects of brassicas on the disease severity index of white rot in eggplant and plant growth parameters in two successive seasons using a hybrid eggplant Darko F1 cultivar. Autolysis products of leaves and roots of the three brassicas plants were analyzed by gas-liquid chromatography-mass spectrometry (GC-MS). The results confirmed that the tested biofumigation plants led to a significant decrease in the mycelial growth and number of sclerotia formation of S. sclerotiorum under laboratory conditions. Cabbage meal was the most effective treatment, resulting in the most reduction in mycelial growth and sclerotia formation. Under field conditions, the incorporation of cabbage, broccoli and cauliflower plants into soil decreased the DSI of white rot during both seasons. This led to a significant increase in plant growth parameters, total fruit yield per plant and total fruit yield per feddan compared to control. Eight glucosinolates were identified by the natural autolysis of leaves and roots of cabbage, broccoli and cauliflower. The autolysis products as isothiocyanates, nitriles and epithioalkane nitriles were analyzed using GC-MS and referred to sinigrin, glucoiberverin, gluconapin, glucoerucin, gluconasturtiin, glucoiberin, glucoraphanin and glucobrassicin glucosinolates. The highest percentage of autolysis products was detected in cabbage roots. Other sulfur compounds and volatile oils with biofumigant activity were also detected in the three investigated plants.
