Ecotoxicology of strobilurin fungicides
Science of The Total Environment, 2020Strobilurin fungicides (SFs), a class of new fungicides, use strobilurin A as a lead compound. However, with excessive production and usage, the SF residues in soil and aquatic ecosystems may lead to environmental pollution. The mechanism of action (MOA) of SFs is respiratory inhibition of fungal mitochondria.

The mould, Sphaerotheca fuliginea, appears as a powdery white growth on the leaves of cucumbers and zucchini (Cucurbita pepo). It damages the plants and causes the leaves to shrivel up. To date, only chemical fungicides are available. However, by-products from milk-processing factories have been proven to kill powdery mildew on zucchini. In many cases,

Xenobiotica, 1986
Of the three main groups of pesticides (insecticides, fungicides and herbicides), fungicides have probably the longest history, dating back to the accidental discovery in 1882 of Bordeaux mixture and the value of copper-based preparations for the control of vine downy mildew disease. In more recent times a wide range of fungicides have become available,

Fifty‐four aryloxyalkanecarboxylic acids have been examined as systemic fungicides. Of these, four which produced negligible damage in broad‐bean seedlings yet conferred systemic fungicidal protection to broad beans against Botrytis fabae and to tomatoes against Alternaria solanixvere studied in detail.

This chapter describes the reproductive and developmental toxicity of herbicides and fungicides in humans and animals. Numerous chemicals including herbicides and fungicides are ubiquitous in the environment. Some of them obviously have the potential to cause reproductive and developmental toxicity.

2 : 3-DICHLORONAPHTHAQUINONE (I) is known to be an effective fungicide. It has been shown to be of value as a seed dressing1; but its use on foliage and fruit is limited because of the possibility of phytotoxic effects2. In an attempt to learn more about the reasons for this damaging action, we have prepared and tested the following compounds for ...

Chromatographic analysis of fungicides
Journal of Chromatography A, 1975The separation and analysis of a wide range of fungicides, by gas, liquid, column, paper, and thin-layer chromatography have been reviewed. Major attention has been given to methods for the identification and quantitation of individual and multiresidues of fungicides in environmental and agricultural samples.

Fungicidal activity of cecropin A
Antimicrobial Agents and Chemotherapy, 1997Cecropin A (CA) fungicidal properties were explored. Nongerminated and germinated Aspergillus spp. and Fusarium spp. conidia were treated with CA. CA achieved complete lethality at < or = 25 microM (99 micrograms/ml) for germinating, but not nongerminating, conidia of Aspergillus spp.

The cationic (Hyamine 3500, Cyprex, or dodine, and Triton X-400), anionic (Atlox G-3300 and Santomerse), and non-ionic (Tritons X-100, X-114, and B-1956 as well as Tween 81) surfactants were compared as inhibitors of respiration, as agents promoting the passage of amino acids out of spores into the surrounding medium, and as inhibitors of germination ...
