Target and non-target site mechanisms of fungicide resistance and their implications for the management of crop pathogens.

Pest Management Science, 2023
BACKGROUND Fungicides are indispensable for high-quality crops, but the rapid emergence and evolution of fungicide resistance have become the most important issues in modern agriculture.

Fungicide resistance management: Maximizing the effective life of plant protection products

Plant Pathology, 2021
Effective crop protection is vital to safeguard food security, but growers are reliant on a limited toolbox in the face of diverse and evolving pathogens. New crop protection methods need to be developed, but it is also important to prolong the effective

Discovery of a Fungicide Candidate Targeting Succinate Dehydrogenase via Computational Substitution Optimization.

Journal of Agricultural and Food Chemistry, 2021
Succinate dehydrogenase (SDH, EC 1.3.5.1) has proven to be an important fungicidal target, and the inhibition of SDH is useful in the treatment of plant pathogens. The discovery of a novel active SDH inhibitor is of high value.

The evolution of fungicide resistance.

Advances in Applied Microbiology, 2015
Fungicides are widely used in developed agricultural systems to control disease and safeguard crop yield and quality. Over time, however, resistance to many of the most effective fungicides has emerged and spread in pathogen populations, compromising disease control. This review describes the development of resistance using case histories based on four

Screening for Fungicides [PDF]

Annual Review of Phytopathology, 1987
Interest in finding new fungicides extends over more than one hundred years (2), but only relatively recently have methods for the mass screening of chemicals been developed ( 1). Initially, tests were simple, with the fungus growing on agar or in droplets containing the chemical (8). Tests on plants were pioneered at the Boyce Thompson Institute (23).

Fungicides and photochemistry: photodegradation of the dicarboximide fungicide vinclozolin [PDF]

Journal of Agricultural and Food Chemistry, 1995
To examine the potential of the fungicide vinclozolin to undergo photochemical reactions on plant surfaces, model experiments lambda > 280 nm) were performed in various organic solvents simulating the plant cuticle environment. On irradiation in 2-propanol and n-propanol vinclozolin was completely degraded within 1 h, but the degradation was ...

The strobilurin fungicides

Pest Management Science, 2002
AbstractStrobilurins are one of the most important classes of agricultural fungicide. Their invention was inspired by a group of fungicidally active natural products. The outstanding benefits they deliver are currently being utilised in a wide range of crops throughout the world.

Studies on the Novel Pyridine Sulfide Containing SDH Based Heterocyclic Amide Fungicide.

Pest Management Science, 2020
BACKGROUND Succinate dehydrogenase (SDH) has been identified as one of the most significant targets for fungicide discovery. Until now, 23 commercial SDHI fungicides have been approved for plant protection since the first launch of carboxin in 1966, and ...

Fungicides and photochemistry photodegradation of the dicarboximide fungicide iprodione

Chemosphere, 1995
The photoreactivity of the dicarboximide fungicide procymidone (1) (3-(3,5-dichlorophenyl)-1,5-dimethyl-3-azabicyclo[3.1.0]hexane-2,4-dione) on plant surfaces was studied by irradiation experiments in different organic solvents simulating the plant cuticle environment.

Fungicides and photochemistry: Photodegradation of the azole fungicide penconazole

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1994
In order to examine the photostability of the fungicide penconazole (1-(2,4-dichloro-beta-propylphenethyl)-1H-1,2,4-triazole, 1) in the field, model experiments with organic solvents were performed. Photodegradation (lambda > 280 nm) of penconazole was found to be more efficient in isopropanol and cyclohexane solution than in the presence of ...
