Trifloxystrobin 肟菌酯
Introduction: Trifloxystrobin is a synthetic derivative of the naturally occurring strobilurins found in several genera of wood-decaying fungi such as Strobilurus tenacellus. It is a strobilurin foliar fungicide. Trifloxystrobin inhibits mitochondrial respiration by blocking electron transfer within the respirator chain. Therefore, trifloxystrobin is a potent inhibitor of 2 fungal spore germination and mycelial growth. It has a high level of activity against many fungal pathogens within the Ascomycete, Deuteromycete, Basidiomycete, and Oomycete classes. Pests controlled by trifloxystrobin include grape and cucurbit powdery mildew, apple scab and powdery mildew, peanut leafspot, and brown patch of turfgrass. It could be applied to cereals, ornamental, vegetables (carrots, asparagus, cucurbits, fruiting vegetables, root vegetables (except radish)), fruits (apples, pears, grapes, strawberries) and tropical crops.

ENVIRONMENTAL FATE
Animals In rats, absorbed from the gastrointestinal tract, rapidly metabolised and quickly and completely eliminated from the body. Plants Metabolic profile is similar for a range of crops. Based on wheat, apple, cucumber and sugar beet metabolism data, trifloxystrobin is considered as the residue of concern for food and feed commodities of plant origin. Soil/Environment Dissipates rapidly from soil and surface water. Soil DT50 4.2-9.5 d. Koc 1642-3745. No leaching potential. In water, DT50 0.3-1 d, DT90 4-8 d.
Usage: Trifloxystrobin was introduced by Novartis Crop Protection AG (became Syngenta AG). It is a strobilurin foliar applied fungicide for control of certain foliar, stem and root diseases.
Application: Biochemistry Inhibits mitochondrial respiration by blocking electron transfer at the Qo centre of cytochrome bc1. Mode of action Mesostemic, broad-spectrum fungicide with preventative and specific curative activity and displaying rain-fastness. Redistributed by superficial vapour movement and also has translaminar activity. Uses Broad spectrum fungicide for foliar use on a wide range of agricultural and horticultural crops in temperate, sub-tropical and tropical climates in open fields or protected under glass and plastic. In Europe its uses will be focussed on cereals (at 50 g/ha), grapes (at 187.5 g/ha), pome fruit (at 75 g/ha), and cucurbit crops (at 187.5 g/ha).Trifloxystrobin is active against fungi in all four classes - Ascomycetes, Deuteromycetes, Basidiomycetes and Oomycetes.
