Introduction and Properties
Fenpyroxymid, under the brand name Orthos, is a phenoxypyrazole acaricide with very high contact and penetration properties that prevents electron transfer in mitochondria. This toxin is used with a rapid knockdown effect for different ages of nymphs, adults, and eggs of mites. Its use in the sensitive stages of mites reduces the consumption of this acaricide. Consecutive use of this product during a crop season should be avoided, as it may cause resistance to develop. Therefore, it is recommended to use this combination once or, if necessary, twice (preferably with the advice of a plant health expert) during a crop season. It should also be noted that the use of another acaricide that has a similar mechanism of action on mites may increase the likelihood of resistance in mites.
Instructions for use
Citrus red mite at 0.5 parts per thousand (for eggs) and 0.5 parts per thousand + 1% Volk oil for adults and nymphs
European red apple mite at 0.5 parts per thousand
Citrus rust mite at 0.5-0.7 parts per thousand
