Aliette

Aliette is the trade name of a systemic fungicide and bactericide whose active ingredient is fosetyl-Al (aluminium tris-O-ethylphosphonate), present at 80% in the formulated product. It is used in agriculture, horticulture and arboriculture to control diseases caused by fungi and fungus-like organisms such as Phytophthora and Verticillium, and to protect against root rot, collar canker, bacterial fire blight and downy mildew. Because it is systemic, the active substance is absorbed by the leaves and translocated throughout the plant, including to the roots, so it must be applied while the foliage is still green and active. A common application protocol is a first spray in late September and a second in late October; although often recommended for conifers, the product is described as effective on all trees. On broadleaf trees the foliage may suffer slightly, but this is considered inconsequential because treatment occurs shortly before natural leaf fall. The brand is associated with Bayer CropScience, and the official product page is hosted on Bayer's Spanish crop-science site as Aliette WG.

Aliette is a long-established crop-protection trade name. Its active ingredient, fosetyl-Al (aluminium tris-O-ethylphosphonate), is a systemic phosphonate fungicide that moves within the plant and is used against oomycetes and fungi such as Phytophthora and Verticillium. The product has been marketed for decades in arboriculture, horticulture and viticulture, and is particularly known for autumn applications on trees. The brand is associated with Bayer CropScience, and current product information is published on Bayer's national crop-science websites, including a Spanish page for Aliette WG. The French Wikipedia entry describes it as the trade name of a systemic fungicide and bactericide composed of 80% fosetyl-Al, used against dieback of plants sensitive to fungi such as Phytophthora or Verticillium, while sparing mycorrhizae and soil fauna. It also protects against root rot, collar canker, bacterial fire blight and downy mildew. The treatment is absorbed by the leaves and transmitted to the roots, so it must be applied while foliage is still green and active. Although often recommended for conifers, it is described as effective for all trees. The safest application protocol is a first spray in late September and a second in late October. On broadleaf trees the foliage may suffer slightly, but this is without consequence because the product is applied shortly before natural leaf fall in autumn.

Systemic fungicide and bactericide for preventive and curative control of Phytophthora, Verticillium, root rot, collar canker, fire blight and downy mildew in trees and other crops.
