In apple, the glycoside phloridzin (1.27) and its aglycone phloretin are thought to inhibit the apple scab fungus Venturia inaequalis. Phloridzin is also an ort/20-dihydroxyphenolic compound, and, like chlorogenic acid, can also be easily converted to a reactive quinone upon attack by a pathogen. Raa (1968) demonstrated that oxidation products of phloridzin inhibit fungal... [Pg.214]

No problems in the field performance of DMIs have been observed yet for the control of apple scab, although strains of Venturia inaequalis with reduced sensitivity to DMIs have been observed in a few field plots. [Pg.323]

Tolkmith (1966) developed the active substance 0,0-diethyl phthalimidophos-phonothioate (ditalimfos 36), which is a very effective fungicide against powdery mildew in apple and cherry orchards, cucumbers and roses, and is also effective against apple scab ( Venturia inaequalis) and diseases caused by Monilia fructicola, etc. (Huisman, 1972 Huisman and Peskett, 1973). In addition to its protective effect ditalimfos also has a curative action, and is virtually nontoxic to warm-blooded organisms. [Pg.308]

Fortunately, already within the currently known examples, important differences in the dynamics of resistance spread and concurrently in the practical consequences can be found. Worst-case examples, represented by pathogens such as cereal powdery mildew or Septoria tritici, are characterized by a rapid spread of resistance within the fungal population over continent-wide distances but are obviously rare. In other cases such as with the apple scab pathogen (Venturia inaequalis), problems remain localized to certain regions or even individual orchards for many years and give a good chance for consequent resistance management.

Also of limited practical importance is some resistance of Venturia inaequalis (causing apple scab) against kresoxim-methyl, which has its origin in the esterase-mediated metabolization of the active substance by the resistant isolates [85]. Target mutations Phel29Leu (yeast numbering) lead only to lower resistance factors in a few fungal species, and seem also to be of minor practical relevance. [Pg.483]
