Insecticides

The classification scheme listed below is adapted from the Insecticide Action Committee Mode of Action Classification (IRAC) V7, September 2010.

Group #	Primary Site of Action	Group Name	Product Name (s)	Risk of Developing Resistance
1A1		carbamate	Furadan 480 F, Lannate, Pirimor 50 DF, Sevin XLR, Vydate L	High
1B	Acetylcholine esterase inhibitors	organophosphate	Agrox B-2, Agrox CD, Counter 15 G, Cygon 480, Imidan 50 WP, Lagon 480, Lorsban 4E, Lorsban 15 G, Malathion 500 E, Monitor 480, Pyrifos 15 G, Pyrifos 50 W, Pyrinex 480 EC, Thimet 15 G	High
2A	GABA-gated chloride channel agonists	chlorinated cyclodiene	Thiodan 4 EC, Thiodan 50 WP, Thionex 50 W	Moderate
3A	Sodium channel modulators	pyrethroid	Concept, Decis 5 EC, Force 3.0 G, Matador 120 EC, Pounce 384 EC, Ripcord 400 EC, Silencer 120EC	High
4A	Nicotinic acetylcholine receptor agonists	neonicotinoids	Admire, Gaucho 480 FL, Concept, Gaucho GS, Poncho 600, Cruiser 5FS, Cruiser 350FS, Helix Xtra, Prosper	Low to Moderate
5	Nicotinic acetylcholine receptor agonists (allosteric, not group 4)	naturalyte/spinosyns	Success 480 SC, Delegate	Low
9B	Selective homopteran feeding blockers	pyridines	Fulfill 50 WG	Low
11	Microbial disruptors of insect midgut membranes	biologicals	Bioprotec CAF, Dipex 2X DF, Novodor, Thurcide HPS	Low
17	Molting disrupters (Diperta only)	cyromazine	Citation 75 WP, Governor 75 WP	Low
21	Mitochondrial complex I electron transport inhibitor	botanicals	Rotenone 5, Rotenone 1% WP, Rotenone 5% WP	Low
23	Inhibitors of acetyl CoA carboxylase	tetronic and tetramic acid derivatives	Movento
24	Mitochondrial complex IV electron transport inhibitors	inorganics (aluminum phosphide)	Fumitoxin, Phostoxin, Gastoxin	Modertae
28	Ryanodine	diamides	Coragen	Low to Moderate

¹ Although sharing the same primary target site, it is possible that not all members of a single major mode of action (MoA) class have been shown to be cross-resistant . However, for the purposes of this classification system, it should be assumed that cross-resistance exists between compounds in any one sub-group.

Fungicides

This classification scheme is based on the Fungicide Resistance Action Committee (FRAC) List, 2010
