Fenbutatin Oxide
苯丁锡
Introduction: Fenbutatin Oxide is an insecticide that specifically target mites (acaricide). It is used primary on fruit trees and nut trees, but is also approved for use on ornamentals. Fenbutatin Oxide is used to control the following: mites, aphids, thrips, mealybugs, whiteflies and scales, although it was originally created as a miticide (acaricide). It is applied only to agricultural sites, as residential use is not permitted. Fenbutatin Oxide may be applied 2-4 times per year at a rate of 1.25-2lbs active ingredient per Acre.

ENVIRONMENTAL FATE
Soil/Environment In soil, it is metabolised to dihydroxy-bis(2-methyl-2-phenyl propyl)stannane and 2-methyl-2-phenylpropyl stannonic acid, presumably ultimately forming tin oxide/hydroxide. In tests in commercial use, there was minimal movement of fenbutatin oxide or its metabolites out of the top 30 cm of soil.
Usage: Fenbutatin Oxide was introduced in USA by Shell Chemical Co. (now DuPont Agricultural Products) and elsewhere by Shell International Chemical Co., Ltd (now BASF AG). It is an acaricide used to control a wide range of phytophagous mites and other insects, such as spidermites, aphids, mealybugs, thrips, whitefiles, scale, in fruit trees including citrus, apples, apricots; currants; vines; nuts; ornamentals, etc.
Application: Biochemistry Inhibitor of oxidative phosphorylation; disruptor of ATP formation. Mode of action Non-systemic acaricide with contact and stomach action. Uses Control of all motile stages of a wide range of phytophagous mites on pome fruit, stone fruit, citrus fruit, soft fruit, vines, bananas, cucurbits, ornamentals, and glasshouse crops. Gives long residual control. Phytotoxicity Phytotoxic to tangerines, tangelos, and some varieties of grapefruit. Otherwise, non-phytotoxic when used as directed.
