Comment

Avid/Abamectin *+
(microbial toxin)

SC

Primarily effective against twospotted spider mite; less effective against mites on conifers; limited systemic movement.

Bifenazate/Floramite*+
(carboxylic acid ester)

HC

This miticide does not kill predators; spider mites only.

Bifenthrin/Talstar*+

(pyrethroid)

NC

Broad spectrum pyrethroid.

Carbaryl/Sevin

(carbamate)

NC

Repeated use may stimulate spider mite reproduction; broad spectrum.

Chlorfenapyr/Pylon*
(pyrrole)

NC

Thrips, mites, foliar nematodes; phyto cautions.

Clofentezine/Ovation*/Savey*
(tetrazine)

HC

This miticide does not kill mite predators; only eggs and immatures.

Dicofol/Kelthane*+
(organochlorine)

NC

Very long residual miticide; kills mite predators.

Dienochlor/Pentac
(chlorinated hydrocarbon)

SC

Short toxicity to predatory mites, but not toxic to predatory beetles.

Etoxazole/TetraSan 5WDG*+

C

Eggs, immatures, eggs in adults.

Fenbuatin-oxide/Vendex*+
(organo-tin)

MC

Conserves predatory mites when used properly. 

Fenpyroximate/Akari*
(phenoxypyrazole)

C

Eggs, immatures; eggs in adults.

Fluvalinate/Mavrik*+
(pyrethroid)

NC

Long residual; broad spectrum.

Hexythiazox/Hexygon*+
(thiazolidine)

HC

Kills only spider mite nymphs and eggs; long residual. Does not kill predators.

Horticultural oil*+

C

Inactive when dry; kills soft bodied insects and pupal stage parasitoids.

Hydrophobic extract of Neem Oil/Triact 70*+
(botanical)

NC

Mites, some insects, foliar diseases.

Imidacloprid/Marathon/Merit+
(chloronicotinyl)

NC

Ability to kill predaceous bugs can cause spider mite outbreaks.  Long residual when systemically applied.

Insecticidal Soap*+

C

Inactive when dry; kills soft bodied insects and pupal stage parasitoids are not killed.

Lambda-cyhalothrin/Scimitar*+
(pyrethroid)

NC

Very long residual; broad spectrum.

Naled/Dibrom8*+
(chlorinated hydrocarbon)

NC

Broad spectrum.

Oxythioquinox/Morestan/Joust+
(dithiocarbonate)

NC

Long residual; broad spectrum.

Phosmet/Imidan+
(organophosphate)

SC

Reportedly low impact on spider mite predators in orchards with long history of pesticide use.

Propargite/Ornamite+
(sulfite ester)

C

Compatible with beneficials.

Pyradiben/Sanmite*+
(pyradazinole)

NC

Lasting effects on mites and predators; immatures only.
