- Active ingredient
- Clofentezine
- Chemical class
- Tetrazine; IRAC Group 10A mite growth inhibitor affecting CHS1, the subgroup it names and shares with hexythiazox and diflovidazin.[2][1]
- Mode of action
- IRAC Group 10A: Mite growth inhibitors affecting CHS1: clofentezine, diflovidazin, hexythiazox[2]
- Signal word
- Clofentezine SC Ovicide/Miticide: Caution[1]
One spray per crop
In greenhouse, saran and shade house culture, apply it only once per crop cycle. Outdoor ornamentals get no more than one application per crop cycle within a year.[1]
For an untested plant, the label suggests two sprays a week apart on 25 or more plants, then watching 7 more days for injury.[1]
Cross-resistance with hexythiazox
IRAC places hexythiazox in the same subgroup as clofentezine because mites resistant to one show cross-resistance to the other, so switching between them is not a true rotation.[2]
Where it is used
Spray at the first sign of mite activity and egg laying, when females, eggs and the youngest mites make up most of the population.[1]
If many adult mites are already present, the label says to tank-mix it with an adult miticide, after checking compatibility and plant safety.[1]
It works through direct spray contact or when mites touch dried residue on leaves, and activity can persist up to 45 days.[1]
The magenta formula may leave a residue on light-colored flowers or foliage, and it can never go through an irrigation system.[1]

Safety and environmental hazards
People
Signal word CAUTION. Handlers wear long sleeves, long pants, shoes and socks, and chemical-resistant gloves. Workers stay out of treated areas for 12 hours, and flowers can't be hand-harvested for 7 days.[1]
Pets
The label is for commercial production sites and states it is not for residential use, so it has no directions for treating around pets at home.[1]
Bees and pollinators
There is no bee statement. The label says it has limited to no effect on beneficial insects, particularly predatory mites, and fits IPM programs that use them.[1]
Fish and water
Keep it at least 100 feet from lakes, reservoirs, rivers, streams, marshes, ponds, estuaries and fish farm ponds, and never spray directly onto water.[1]
Common questions
- Does clofentezine kill adult mites?
- It is described as highly active on mite eggs and early stages. With a heavy adult population, the label calls for tank-mixing an adult miticide.[1]
- How long does clofentezine last?
- The label reports activity and persistence up to 45 days after application, which may delay or remove the need for other miticides.[1]
- Can I use Clofentezine SC on my home plants?
- No. It is labeled for commercial ornamental production and says Not for Residential Use.[1]
