Remarks (internal):A toxin produced by F. equiseti caused yellowing and necrosis of fodder crops (55, 5248). Control is by application of thiram and difolatan (56, 2487). Non-sporulating strains are often isolated (54, 2536).

Description:Fusarium equiseti (Corda) Sacc., Sylloge Fungorum 4: 707-708, 1886.
Conidial state of Gibberella intricans Wollenw., Z. ParasitKde 3: 332, 1931.
Selenosporium equiseti Corda, Icones Fungorum 2: 7, 1838.
Fusarium scirpi Lamb. & Fautr., 1894.
Cultures when first isolated white, with a floccose white mycelium tinged with peach, later (7-10 days) changing to beige and finally deep olive buff; from below the initial peach colour changes to vinaceous fawn and finally dark brown. Macroconidia only produced, developing sparsely at first from simple lateral phialides but production increasing with the formation of compact penicillately branched conidiophores after about 10 days, falcate, with a well developed pedicellate foot cell and an attenuated apical cell which curves inwards, with 4-7 thin but distinct septa, 22-60 x 3,5-6 µm (av. 50 x 4,5 µm). Chlamydospores intercalary, solitary, in chains or knots, globose, 7-9 µm diam. Perithecia rare, developing sparsely, ovoid with a rough outer wall, 200-350 µm high, 180-240 µm diam. Asci clavate, with 4-8. Ascospores 21-33 x 4-5·5 µm, hyaline, fusoid, 2-3-septate.
Hosts: Fusarium equiseti has been isolated from a wide range of hosts, especially tropical hosts belonging to the following genera: Agave, Allium, Apium, Arachis, Beta, Brassica, Cajanus, Carica, Chrysanthemum, Cicer, Citrullus, Citrus, Cocos, Coffea, Cola, Crotalaria, Cucumis, Cucurbita, Cupressus, Daucus, Dianthus, Elaeis, Eucalyptus, Ficus, Fragaria, Glycine, Gossypium, Helianthus, Hevea, Hordeum, Linum, Luffa, Lycopersicon, Macadamia, Mangifera, Manihot, Musa, Nicotiana, Oryza, Panicum, Papaver, Pennisetum, Phaseolus, Pinus, Pisum, Prunus, Pyrus, Rosa, Solanum, Sorghum, Theobroma, Trifolium, Triticum, Vicia, Vigna, Zea, Zingiber; also widespread in soil.
Disease: Pathogenic to cucurbits and avocado (54, 2536; 52, 2674; 50, 3350). Causes tuber rot of Cycas (54, 168) and stalk rot of maize (54, 4915). Also isolated from diseased Piper (52, 1993) and mung bean (Phaseolus aureus, 50, 397). Pathogenic to cereals during seedling stage (56, 3493) and also causing root rot (56, 2487).
Geographical distribution: World wide; very frequent in tropical and subtropical areas but occurs also in
temperate regions.
Physiological specialization: Pathogenicity generally non-specific (52, 2674; 53, 1144).
Transmission: Infection and stalk rot of maize caused by F. equiseti appears to be by air-borne spores (54, 4915) although in most occurrences wounding or damage to the host appears to be necessary for infection (53, 4642). Infected soil may cause seedling blight (50, 1397).
