Triflumuron is a benzoylurea insecticide
Of the 11insecticides identified below as benzoylureas, 10 are organofluorines.

Benzoylureas are an entirely different class of insecticides that act as insect growth regulators (IGRs). Rather than being the typical poisons that attack the insect nervous system, they interfere with chitin synthesis and are taken up more by ingestion than by contact. Their greatest value is in the control of caterpillars and beetle larvae. Benzoylureas were first used in Central America in 1985, to control a severe, resistant leafworm complex (Spodoptera spp., Trichoplusia spp.) outbreak in cotton. The withdrawal of the ovicide chlordimeform made their control quite difficult due to their high reistance to almost all insecticide classes, including the pyrethroids. The first benzoylureas were introduced in 1978 by Bayer of Germany, triflumuron (Alsystin(r)) being the first. Others appearing since then are chlorfluazuron (Atabron(r), Helix(r)), followed by teflubenzuron (Nomolt(r), Dart(r)), hexaflumuron (Trueno(r), Consult(r)), flufenoxuron (Cascade(r)), and flucycloxuron (Andalin(r)). Others are flurazuron, novaluron, and diafenthiuron. Lufenuron (Axor(r)) is the newest addition to this group, appearing in 1990. Surprisingly, none of these are registered in the U.S. The only benzoylurea registered in the U.S. is diflubenzuron (Figure 21) (Dimilin(r), Adept(r), Micromite(r)). It was first registered in 1982 for gypsy moth, cotton boll weevil, most forest caterpillars, soybean caterpillars, and mushroom flies, but now with a much broader range of registrations.
Mode of action--The benzoylureas act on the larval stages of most insects by inhibiting or blocking the synthesis of chitin, a vital and almost indestructible part of the insect exoskeleton. Typical effects on developing larvae are the rupture of malformed cuticle or death by starvation. Adult female boll weevils exposed to diflubenzuron lay eggs that do not hatch. And, mosquito larvae control can be achieved with as little as 1.0 gram of diflubenzuron per acre of surface water.

October 2002 - Factsheet. Guidelines for producing European eco-label and nil residue wool. Western Australia Department of Agriculture.
No diflubenzuron or triflumuron to be used, as residue levels are likely to exceed limits.
Eco-label wool does not mean nil residue wool and the current limits for pesticide levels can be achieved fairly easily using standard production systems. The pesticide limits for greasy wool are:
Total synthetic pyrethroids (SP) less than 0.5 mg/kg
Total organophosphates (OP) less than 2 mg/kg
Total insect growth regulators (IGR)* less than 2 mg/kg
*IGRs cover diflubenzuron (e.g. Magnum, Strike, Fleececare etc.) and triflumuron (e.g. Zapp, etc.). Use of either of these chemicals is likely to exceed this level, e.g. expected residues from using triflumuron (e.g. Zapp etc.) off-shears is 2530 mg/kg...
