Thiophanate-methyl 66% + Kresoxim-methyl 7.5% WDG
Thiophanate-methyl NOMENCLATURE
Common name thiophanate-methyl (BSI, E-ISO, (m) F-ISO, ANSI, JMAF)
IUPAC name dimethyl 4,4′-(o-phenylene)bis(3-thioallophanate)
Chemical Abstracts name dimethyl [1,2-phenylenebis(iminocarbonothioyl)]bis[carbamate]
CAS RN [23564-05-8]
Thiophanate-methyl APPLICATIONS
Thiophanate-methyl Biochemistry Carbendazim (q.v.) precursor.
Thiophanate-methyl Mode of action Systemic fungicide with protective and curative action. Absorbed by the leaves and roots.
Thiophanate-methyl Uses A fungicide used at 30-50 g/ha, and effective against a wide range of fungal pathogens, including: eyespot and other diseases of cereals; scab on apples and pears; Monilia disease and bitter rot on apples; Monilia spp. on stone fruit; canker on fruit trees; powdery mildews on pome fruit, stone fruit, vegetables, cucurbits, strawberries, vines, roses, etc.; Botrytis and Sclerotinia spp. on various crops; leaf spot diseases on beet, oilseed rape, celery, celeriac, etc.; club root on brassicas; dollar spot, Corticium, and Fusarium spp. on turf; grey mould in vines; blast in rice; Sigatoka disease in bananas; and many diseases in floriculture. Also used on almonds, pecans, tea, coffee, peanuts, soya beans, tobacco, chestnuts, sugar cane, citrus fruit, figs, hops, mulberries, and many other crops. Used additionally as a wound protectant for pruning cuts on trees.
Thiophanate-methyl Compatibility Incompatible with alkaline and copper-containing compounds.
Kresoxim-methyl NOMENCLATURE
Common name krésoxim-méthyle ((m) F-ISO); kresoxim-methyl (BSI, E-ISO)
IUPAC name methyl (E)-methoxyimino[2-(o-tolyloxymethyl)phenyl]acetate
Chemical Abstracts name methyl (αE)-α-(methoxyimino)-2-[(2-methylphenoxy)methyl] benzeneacetate CAS RN [143390-89-0]
Kresoxim-methyl APPLICATIONS
Kresoxim-methyl Biochemistry Quinone outside Inhibitor. Inhibits mitochondrial respiration by blocking electron transfer between cytochrome b and cytochrome c1, at the ubiquinol oxidising site. Selectivity is partly due to enzymic de-esterification within plants.
Kresoxim-methyl Mode of action Fungicide with protective, curative, eradicative and long residual disease control; acts by inhibiting spore germination. Redistribution via the vapour phase contributes to activity.
Kresoxim-methyl Uses Control of scab in apples and pears (Venturia spp.); powdery mildew on apples (Podosphaera leucotricha), vines (Uncinula necator), cucurbits (Sphaerotheca fuliginea) and sugar beet (Erysiphe betae); mildew (Erysiphe graminis), scald (Rhynchosporium secalis), net blotch (Pyrenophora teres) and glume blotch (Septoria nodorum) on cereals; and mildew (Leveillula taurica, Erysiphe spp., Alternaria spp.) on vegetables.
