Occupational exposure to fosetyl-Al fungicide during spraying of ornamentals in greenhouses

Archives of Environmental Contamination and Toxicology, 1987
Eight workers were monitored by the dermal patch/hand rinse technique for exposure to the fungicide aluminum tris-o-ethyl phosphonate [fosetyl-Al or ALIETTE®] during treatment of ornamentals in a greenhouse, using commercial back-pack sprayers. The mean total dermal exposure for mixers was 512 μg a.i./hr and for applicators 389 μg a.i./hr.

Ethephon and fosetyl residues in fruits from São Francisco Valley, Brazil

Food Additives & Contaminants: Part B, 2019
This survey describes the occurrence of Ethephon (ETH) and Fosetyl in fruits intended for export produced in the São Francisco Valley, Brazil. The determination of these compounds was carried out by the QuPPe-method (Quick Polar Pesticides Method), which was optimised and successfully validated according to the SANTE/11813/2017.

Residue studies of fosetyl aluminium in citrus fruit on LC-MS/MS

Agricultural Research Journal, 2021
A two year residue study of Fosetyl Aluminium on citrus was carried out following five applications of Fosetyl Aluminium 80% WP @ 3.2 g a.i./L water and 6.4 g a.i./L water at an interval of one month. An easy and simple methodology was standardized for the extraction of residues in citrus fruit and soil followed by estimation and confirmation on LC-MS ...

Aluminum-mediated fosetyl-Al effects on peroxidase secreted from grapevine cells

Environmental and Experimental Botany, 1994
Abstract Grapevine (Vitis vinifera cv. Monastrell) suspension cell cultures were treated with 1.5 mM fosetyl-Al for 48 hr at 25°C to test whether this compound, which is frequently used a as systemic fungicide for grapevine diseases caused by oomycetes, is capable of inducing defense reactions in healthy non-diseased grapevine cells.

Duration of Fungicidal Effect Following Injection of Apple Trees with Fosetyl‐Al

Journal of Phytopathology, 1989
AbstractInjection of 4 g a.i. of fosetyl‐Al into 10‐year‐old apple trees in the growing season gave fungicidal effects in both unlignified xylem tissue and phloem/cortical tissue of the shoots and trunk base within three days. These fungicidal effects persisted for at least 15 months.Phytotoxicity, manifested as browning of the lignified xylem, was ...

Subcellular alterations in Phytophthora infestans infecting tomato leaves treated with fosetyl-Al

Pesticide Biochemistry and Physiology, 1992
Abstract The quantitative changes in organelles of Phytophthora infestans in tomato leaves that had previously been treated with the systemic fungicide fosetyl-Al (2000 μg · ml −1 ) were measured by electron microscopy 15 and 18 hr after inoculation.

Fosetyl-Al alters the respiratory response in Phytophthora nicotianae var. nicotianae-infected tobacco

Physiological and Molecular Plant Pathology, 1989
Abstract Inoculation of susceptible 21-day-old tobacco (cv. 26T68) seedlings by zoospores of the black shank fungus ( Phytophthora nicotianae var. nicotianae ) is followed by rapid colonization, cellular degradation and metabolic disruption. Oxygen consumption increases rapidly in the first 13 h after inoculation from 15·3 μmol g −1 h −1 to 31·4 ...

Efficacy of Fosetyl-Al for Control of Some Bacterial Diseases on Ornamentals

Plant Disease, 1993
Several factors, including pH and timing and number of applications, affect the efficacy of fosetyl-Al for controlling bacterial disease on ornamentals. Although pH may be a factor in the efficacy of fosetyl-Al for sensitive bacteria such as strains of Xanthomonas campestris pv.

Influence of fosetyl-Al on phytoalexin accumulation in the Plasmopara viticola-grapevine interaction

Physiological and Molecular Plant Pathology, 1989
The effect of fosetyl-Al on phytoalexin accumulation was investigated in non-inoculated and Plasmopara viticola-inoculated leaf discs of a susceptible cv. (Riesling) intermediate resistant (V. rupestris 6544), and resistant cv. (Castor) Vitis spp. In non-inoculated tissues fosetyl-Al induced only a weak phytoalexin response.

Chitosan-Coated Fosetyl-Al Nanocrystals’ Efficacy on Nicotiana tabacum Colonized by Xylella fastidiosa

Phytopathology®
Xylella fastidiosa ( Xf) is a quarantine plant pathogen capable of colonizing the xylem of a wide range of hosts. Currently, there is no cure able to eliminate the pathogen from a diseased plant, but several integrated strategies have been implemented for containing the spread of Xf.
