Pythium deliense causing severe damping-off of cucumber seedlings and its biological control by soil bacteria

1996

Abstract Pythium deliense Meurs was isolated from cucumber plant debris and was found to be highly pathogenic to cucumber seedlings, causing severe damping-off disease. The fungus however was completely inhibited by a soil bacterium SU-48.1. In vitro and in vivo studies reveal that the disease can be controlled by using this bacterium. The details of the parasitic fungus, the antagonism between the fungus and the bacteria, and the biological control of the disease, are described in this article.

Contributo per una visione contemporanea dell’azienda agricola: tra sostenibilità e sfide del mondo digitale

2023

Le sfide che l’umanità sta affrontando e da cui dipende la sopravvivenza del pianeta, il diffondersi nell’ambito dell’attività agricola di tecnologie digitali sempre più avanzate e la necessità di adottare un approccio sostenibile che preservi le risorse a tutela delle generazioni future hanno condotto l’azienda agricola a cambiare gradualmente volto. Questo libro mira a contribuire a un’aggiornata riflessione sul ruolo dell’imprenditore agricolo e dell’azienda da lui condotta, osservandone l’organizzazione e composizione alla luce delle regole che oggi la disciplinano e guardando alle innovazioni necessarie a garantire il raggiungimento dei pressanti obiettivi climatici e ambientali verso …

Chemical Ecology of Insect Parasitoids: Towards a New Era

2013

Over the course of evolutionary time, insect parasitoids have developed diverse strategies for using chemical compounds to communicate with various protagonists within their environment (i.e. conspecifi cs, their hosts, and the plants on which their hosts are living). Unravelling the evolutionary meaning of such chemical communication networks not only provides new insights into the ecology of these insects but also contributes to improving the use of parasitoids for the control of insect pests in biological control programmes. A book covering our current knowledge of the chemical ecology of insect parasitoids is therefore particularly timely and will appeal to a large number of potential r…

Recent advances in the application of innovative food processing technologies for mycotoxins and pesticide reduction in foods

2020

Abstract Background Agricultural products are a vital component of the human diet. However, these products can be contaminated by health-threatening pesticides and mycotoxins due to improper farming and storage practices. Besides, pesticide pollution can be also regarded as environmental pollution and pesticide reduction is among the Sustainable Development Goals (SDGs). While these hazardous chemicals are stable during several traditional food processing, innovative food processing technologies, including high-pressure processing (HPP), pulsed electric fields (PEF), cold plasma (CP), supercritical carbon dioxide (SC-CO2), and ultrasound (USN) processing, have been found to have good potent…

128 Development of a job-exposure matrix (JEM) to describe pesticide exposure in Spanish workers (1996–2005)

2013

Objectives Pesticides are intensively used in Spain in a wide range of economic activities such as agriculture, farming, wood treatments or pest control, reaching in 2005 a consumption of more than 100,000 ton/year. Exposure to these substances has been proven to have negative effects on human health. However, there is little information available regarding the levels and frequency of exposure for workers, or the job titles associated with the worst exposure indicators. This study aimed to collect the available information on occupational pesticide exposure in Spain as a job-exposure matrix (JEM). Methods The work was carried out in the context of MatEmESp Project, which aims to build a Spa…

Security of information in IT systems

2005

The aim of the paper is to increase human awareness of the dangers connected with social engineering methods of obtaining information. The article demonstrates psychological and sociological methods of influencing people used in the attacks on IT systems. Little known techniques are presented about one of the greater threats that is electromagnetic emission or corona effect. Moreover, the work shows methods of protecting against this type of dangers. Also, in the paper one can find information on devices made according to the TEMPEST technology. The article not only discusses the methods of gathering information, but also instructs how to protect against its out-of-control loss.

In vitro effect of organophosphate pesticides, Malathion and chlorpyriphos, on lipid peroxidation and antioxidant enzymes

Two new triterpene saponins from Eryngium campestre.

2005

Two new triterpene saponins, 3-O-beta-D-glucopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucuronopyranosyl-22-O-angeloyl-R1-barrigenol (1) and 3-O-beta-D-glucopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucuronopyranosyl-22-O-beta,beta-dimethylacryloyl-A1-barrigenol (2), were isolated from the roots of Eryngium campestre (Apiaceae). Their structures were established mainly by 2D NMR techniques and mass spectrometry.

Tocopherol, fatty acid and phytosterol content in seeds of nine wild taxa of Sicilian Brassica (Cruciferae)

2010

The purpose of this study was to determine tocopherol (Toc), fatty acid and phytosterol content in dry seeds of nine wild taxa of Sicilian Brassica sect. Brassica. Analyses were performed by gas chromatography (GC)-mass spectroscopy (MS). The biochemical analysis of dry seeds showed that in the nine taxa examined, α - and γ -Toc were the major isomers, δ - Toc was present in traces and β -Toc was never found. All taxa had a similar fatty acid composition with C 16:0 (357.2 mg kg − 1 DW), C 18:1 (393.94 mg kg − 1 DW) and C 22:1 (618.29 mg kg − 1 DW) acids present in higher amount. Unsaturated fatty acids (52.5–66.5%) were more abundant than saturated (33.5–47.5%) ones relative to the total f…
