“…The soil amendments were performed on samples taken at 50% anthesis, as this is the plant development stage when glucosinolate levels peak . This Brassica has shown potential as a cover crop in vineyards and as a rotation crop in rotation programmes that include annual crops, such as planting material in grapevine nurseries . We used propamocarb + fosetyl‐Al because it is widely used for the control of other soilborne diseases in horticultural Spanish nurseries and, given the lack of chemicals registered for use against black‐foot disease, its efficacy against black‐foot under field conditions had not yet been demonstrated.…”

“…Biofumigation, consisting of the incorporation of plant residues that slowly release their bioactive compounds into the soil, has been successfully used to control PPNs since the 19th century . Compounds resulting from field biofumigation have proven nematicidal activities, and the best example is isothiocyanates emitted by brassicas . In the last decade, studies addressing VOCs released by plant residues have revealed a number of molecules with nematicidal activity similar to commercial nematicides, therefore further studies are needed to identify VOCs emitted in biofumigation processes.…”

BACKGROUND Plants emit volatile organic compounds (VOCs) with several functions, including toxicity to plant‐parasitic nematodes (PPNs). However, the toxicity of VOCs from watercress leaves (Nasturtium officinale) and passion fruit seeds (Passiflora edulis) against PPNs has not yet been studied. RESULTS Biofumigation with watercress leaves and passion fruit seeds reduced the infectivity and reproduction of Meloidogyne incognita in tomato plants. The VOCs emitted by watercress leaves and passion fruit seeds caused immobility of M. incognita second‐stage juveniles (J2). The reduction in infectivity and reproduction of M. incognita reached 89% and 99%, respectively, when J2 were exposed to watercress VOCs. Additionally, water exposed to VOCs emitted by watercress caused 79% M. incognita J2 mortality. The volatilome of the toxic water contained 12 compounds, mainly alcohols. The emissions from watercress leaves and passion fruit seeds contained 26 and 12 compounds, respectively, according to gas chromatography–mass spectrometry analysis. The 1‐octanol occurring in watercress emissions demonstrated in vitro and in vivo nematicidal activity against M. incognita, with a lethal dose necessary to cause 50% mortality (LC50) of 382.5 μg mL−1. CONCLUSIONS Watercress leaf and passion fruit seed macerates emitted VOCs with nematicidal activity against M. incognita. The compound 1‐octanol identified in watercress emissions may be useful for the nematicide‐producing industry. © 2019 Society of Chemical Industry

“…In fact, glucosinolate concentrations and the resulting production of different forms of isothiocyanates vary greatly among Brassica species and even among cultivars within each species [58], and are also affected by environmental conditions and plant development [59,60]. This could explain in parts the lack of efficacy in reducing potato diseases in the present work, as FR is known to have moderate glucosinolate content [61] as compared to other Brassicaceae species. In addition, in the field, the expected isothiocyanates concentrations are once more lower, because of a poor release efficiency of these compounds due to incomplete tissue maceration with a mulching implement.…”

Potato is threatened by several soil-borne fungi causing wilt and root rots. In this study, two fodder radish (Raphanus sativus L.) (FR) cultivars (cvs. Boss and Defender), used as green manure preceding a potato crop, were evaluated for their suppressive effects against wilt incidence and severity, potato growth and yield as compared to animal manure. The essay was carried out in a completely randomised design with three types of organic amendment and two potato cultivars (cvs. Spunta and Royal). Incidence of potato wilting noted 100 days post planting (DPP) was high, exceeding 70%, for all soil amendments tested. The extent of vascular discoloration varied depending on amendments used where cv. Defender behaved as the control while the highest extent was noted on potato plants grown in cv. Boss amended plots. As compared to animal manure, the application of cvs. Boss and Defender had increased by 48.43 and 41.28% the incidence of vascular discoloration on cv. Spunta, respectively, while on cv. Royal, only cv. Defender had reduced this parameter by 16.32%. Fungal isolations performed from roots and stems revealed the involvement of several soil-borne pathogens in the recorded plant wilting. Soil manuring using cvs. Boss and Defender FR resulted in significant increment in average stem number per plant and aerial part fresh weight by 22.79 and 21.32% and by 34.62 and 27.03%, respectively, as compared to animal manure. At 100 DPP, potato root fresh weight increase by 8.7 and 33.49% was noted on cv. Spunta compared to 30.34 and 23.48% recorded on cv. Royal. Potato tuber yield was improved by 38.28 and 10.7% and by 28.44 and 27.62% in cvs. Spunta and Royal, respectively, relative to animal manure. The use of FR as green manure may be implemented in the integrated management of soil-borne diseases for the enhancement of potato yield.
