Apple scab control

Such situations arose many years after commercial Introduction In the cases of Dodlne for apple scab control, Kltazin P for rice blast control, and benomyl for eyespot control In cereals. However, negative findings in glasshouse and field experiments at least indicate that a build-up of resistance is unlikely to happen quickly, so that there is more time left for development and implementation of antiresistance strategies. 

Other materials based on EDA have also been suggested as fungicides. The most important of the imida2oline type (162) is 2-heptadecyl-2-imida2oline (163), prepared from EDA and stearic acid [57-11-4]. It is used as the acetate salt for control of apple scab and cherry leaf spot. A 2 1 EDA—copper sulfate complex has been suggested for control of aquatic fungi (164).

Folpet is a protective leaf fungicide. Its mode of action inhibits normal cell division of a broad spectrum of microorganisms. It is used to control cherry leaf spot, rose mildew, rose black spot, and apple scab. It is used on berries, flowers, ornamentals, fruits and vegetables, and for seed- and plant-bed treatment. Folpet also finds use in paints, plastics, and treatment of internal and external structural surfaces of buildings to control fungal attack.50,52... 

Protection Offered Sulfur can be purchased alone or mixed with other insecticides and inorganic fungicides to control a wide variety of garden pests. Use sulfur as an insecticide to control insects and mites on fruit trees and citrus. You can also use sulfur as a protectant fungicide. It is effective against apple scab, brown rot of stone fruits, powdery mildews, rose black spot, rusts, and other plant diseases on many crops, including grapes, potatoes strawberries, and tomatoes. 

For tree fruits such as apples (Table IX), low rates of 2-4 grams active ingredient per 100 liters of spray give near-perfect control of both major diseases, scab and powdery mildew excellent cedar apple rust control is also observed at these rates. Standards for these tests include both sterol inhibitors (fenarimol and bitertanol) and non-systemic protectant fungicides (sulfur and captan). 

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. 

Folpet inhibits cell division in many microorganisms. As a fungicide, it is used to control cherry leaf spot, rose mildew, rose black spot, and apple scab and is also used on berries, flowers, fruits, and vegetables for seed treatment. 

Chloro-3-(p-chlorophenoxy)-l,2,6-thiadiazin-4-one (301 R = 4-C1C6H40) is used in low concentration (80 ppm) for the control of apple scab <85USP4497807>, while 3,6-dichloro-1,2,6-thiadiazin-... 

The quinoline derivative quinoxyfen controls exclusively powdery mildews in cereals and broadleaved crops whereas phenylpyrroles such as fludioxonil are used as foliar, post harvest and seed treatment fungicides against a broad range of pathogens such as Botrytis cinerea and apple scab (Table 12.10). 

Fenbuconazole (Table 17.11) is a triazole fungicide intended for use as an agricultural and horticultural fungicide spray for the control of leaf spot, yellow and brown rust, powdery mildew and net blotch on wheat and barley and apple scab, pear scab and apple powdery mildew on apples and pears. Fenbuconazole was already presented to the public in 1988 by Driant et al. [43].
