SPLAT PBW 30M-1TM:
Mating Disruption of the Pink Bollworm Moth, Pectinophora
gossypiella
EPA Product #: 08286-2
SPLAT (Specialized Pheromone and Lure Application Technology) is an
amorphous polymer matrix for the sustained release of insect
pheromones. SPLAT PBW 30M-1 provides control of the pink
bollworm by disrupting mating behavior.

Pest: Pink bollworm (Pectinophora gossypiella)
Crops: Cotton
Application rate: 1 kg/a
Means of application: Aerial, tractor, spatula
Duration: Varies by application method (and thus dollop size),
2 applications should last the season
Field Tests:
- Tacna, AZ
SPLAT PBW 30M-1 and SPLAT PBW 30M-1 w/ cypermethrin (SPLAT
PBW A&K) were hand-applied
at 1 kg/a to determine if the addition of cypermethrin to a
mating disruption formulation further decreases moth counts.
One plot was treated with the
industry standard, PBW rope, at the prescribed rate of 500/ha.
Three plots received SPLAT PBW A&K and 5 plots were treated with SPLAT
PBW. Of these 5 plots, 2 received the full dose (1 kg/a) of
SPLAT and 3 received 50%
of the full dose (0.5 kg/a). When trap catch throughout the
fields was analyzed, all formulations performed similarly.
However, when we look at
just the traps in the middle of the field, we see that SPLAT
formulations slightly outperformed Rope in efficacy and longevity.
Fields treated with
SPLAT A&K had slightly more moths than those fields treated with the mating
disruption formulations.

SPLAT PBW 30M-1 was applied on the ground and aerially at 333g/a
(first application) or 666g/a (second application). When compared
to the control, both applications resulted in at least 30 days
of suppression with less than 1 moth/trap/day. The ground application
lasted longer, which
is to be expected due to the larger dollop sizes (approximately
1g) and nearly direct application to the 6-leaf stage plants.
The aerial
application
performed very well, considering the small dollop size (0.5-4mm)
and the nature of aerial applications which result in non-foliar
applications (the
SPLAT landed everywhere, not just on the plants).
SPLAT has proven its effectiveness in mating disruption,
lure and attract & kill programs for many insect pests
(such as codling moth, oriental fruit moth, pink bollworm,
gypsy moth, brazilian apple leafroller), and ISCA welcomes
collaborative efforts to develop new SPLAT applications.
