Relative Toxicities of Insecticides Used in Cilantro and Parsley to Natural Enemies and Honey Bees

(Reviewed 12/15, updated 12/15, corrected 10/16)

In this Guideline:


Common name (Example trade name) Mode of action1 Selectivity2 (Affected groups) Predatory mites3 General predators4 Parasites4 Honey bees5 Duration of impact to natural enemies6
acetamiprid (Assail)± 4A moderate (sucking insects, larvae) 7 8 II moderate
azadirachtin(Neemix, Aza-Direct) un broad (insects, mites) M L/M L/M II short
Bacillus thuringiensis ssp. aizawai (Xentari) 11A narrow (caterpillars) L L L II short
Bacillus thuringiensis ssp. kurstaki 11A narrow (caterpillars) L L L III short
Beauveria bassiana (BotaniGard) un broad (insects) II
chlorantraniliprole (Coragen) 28 narrow (primarily caterpillars) L L L/M III short
dinotefuran (Venom)± 4A narrow (sucking insects) L L I short
emamectin benzoate (Proclaim)± 6 narrow (caterpillars) I
flonicamid (Beleaf)± 9C narrow (aphids) L L L III short
flupyradifurone (Sivanto) 4D Narrow (aphids, leafhoppers) II
indoxacarb (Avaunt)± 22A narrow (caterpillars) L L L I moderate
insecticidal soap (M-Pede)± un broad (exposed insects, mites) M M M III short
methomyl (Lannate)± 1A broad (insects, mites) H H H I moderate
methoxyfenozide (Intrepid) ± 18 narrow (caterpillars) L L L II short
narrow range oil (Glacial Spray Fluid)+ broad (exposed insects, mites) L9 L L II short to none
neem oil (Trilogy) un broad (soft-bodied insects) L L L II short
permethrin (Ambush, Pounce)± 3A broad (insects, mites) L H H I long
pymetrozine (Fulfill)± 9B narrow (aphids, whiteflies) L L L II short
rosemary oil (Hexacide) un broad (exposed insects, mites) L L L III
spinetoram (Radiant) 5 narrow (caterpillars, thrips, whiteflies, aphids, leafminers) L/H M10 L/M II moderate11
spinosad (Success, Entrust) 5 narrow (caterpillars, whiteflies, aphids, leafminers) L M10 L/M II moderate10
spirotetramat (Movento)± 23 narrow (aphids, whiteflies) L L L II short
thiamethoxam (Platinum)± 4A narrow (sucking insects) M I moderate
zeta-cypermethrin (Mustang) 3A broad (insects, mites) H M M I moderate
H = high    M = moderate      L = low     — = no information
1 Rotate chemicals with a different mode-of-action group number, and do not use products with the same mode-of-action group number more than twice per season to help prevent development of resistance. For example, the organophosphates have a group number of 1B; chemicals with a 1B group number should be alternated with chemicals that have a group number other than 1B. Mode-of-action group numbers (un = unknown or uncertain mode of action) are assigned by IRAC (Insecticide Resistance Action Committee).
2 Selectivity: Broad means it affects most groups of insects and mites; narrow means it affects only a few specific groups.
3 Generally, toxicities are to western predatory mite, Galendromus occidentalis.
4 Toxicities are averages of reported effects and should be used only as a general guide. Actual toxicity of a specific chemical depends on the species of predator or parasite, environmental conditions, and application rate.
5 Ratings are as follows: I–Do not apply or allow to drift to plants that are flowering; II–Do not apply or allow to drift to plants that are flowering, except when the application is made between sunset and midnight if allowed by the pesticide label and regulations; III–No bee precaution, except when required by the pesticide label or regulations. For more information, see Bee precaution pesticide rating.
6 Duration: short means hours to days; moderate means days to 2 weeks; and long means many weeks or months.
7 May cause flare-ups of spider mite populations.
8 Acute toxicity low but reproductive capacity is impacted.
9 Rating depends on rate used.
10 Toxic against some natural enemies (predatory thrips, syrphid fly larva, beetles) when sprayed and up to 5 to 7 days after, especially for syrphid fly larvae.
11 Residual is moderate if solution is between pH of 7 to 8.
± Registered on parsley, not on cilantro.
+ Registered on cilantro, not on parsley.
