CONTROL GUIDE
Annual Bluegrass Weevil (ABW)
Atexzo®
(isocycloseram; IRAC 30)
Suprado®
(novaluron; IRAC 15)
Atexzo (isocycloseram; “Plinazolin” technology) is an IRAC Group 30 insecticide/miticide with contact and ingestion activity for ABW adult and larval control (all damaging stages), enabling broad timing flexibility compared to other products that only control ABW larvae. The unique mode of action is an excellent rotational tool for resistant management on ABW. For best results, use Atexzo in a programmed approach with other larvaecides such as Acelepryn and Ference. Atexzo also controls other insect pests like surface feeding caterpillars, European crane fly, and billbugs when applications are timed and targeted appropriately.
Suprado contains novaluron and is an IRAC Group 15 insect growth regulator that interferes with chitin production during molting. Suprado disrupts ABW development and controls ABW more gradually vs rapid knockdown like other insecticides. It is effective across multiple ABW life stages and can be applied during adult and all larval life stages to deliver consistent control with a high degree of flexibility. As a unique IGR mode of action, Suprado is an excellent rotational option, especially in programs that frequently rely on diamide chemistries or synthetic pyrethroids for primary control.
MatchPoint®
(spinosad; IRAC 5)
Tetrino®
(tetraniliprole; IRAC 28)
MatchPoint contains spinosad and is an IRAC Group 5 insecticide to stop ABW feeding immediately and control larvae from 1st through 5th instar via contact and ingestion. It is best used as a later stage, rescue treatment in programs or in situations where diamide or pyrethroid resistance is suspected. Matchpoint is formulated with a unique lignin component that helps to reduce UV degradation of the active ingredient spinosad, which allows post-application irrigation to be delayed up to 24 hours.
Tetrino contains tetraniliprole and is a Group 28 (diamide) insecticide promoted for fast-acting, systemic control of ABW larval stages, with rapid feeding cessation after exposure. Target early-mid stage instar larvae with a preventive to early-curative timing. Tetrino can also be effective on later stage larvae outside of the plant. For best results, combine with other effective products such as an adulticide and Dylox in a programmed approach. Tetrino also controls many other damaging insect pests like surface feeding caterpillars and white grub grubs when applications are timed and targeted appropriately.
Dylox
(trichlorfon; IRAC 1B)
Ference®
(cyantraniliprole; IRAC 28)
Dylox is a fast-acting contact insecticide that works well on late-stage ABW larvae feeding outside of the plant. Dylox can be effective in rescue treatments when watered in immediately, given its ability to move through thatch compared to many other insecticides. Dylox can serve as an effective rotational active ingredient as a non-diamide chemistry in programs.
Ference contains cyantraniliprole (anthranilic diamide; IRAC 28) for systemic control of ABW larval instars at all damaging stages (1–5), including larvae inside stems (early) and later instars feeding outside the stem. Ference is best used in the spring and early summer as a first-line attack on ABW larvae, but can be incorporated into programs for later generations to target asynchronous populations because it covers multiple larval stages rather than a narrow timing window.
Always read and follow label instructions. All products may not be registered for use in all states.
