Aphids, Spirea, - Under Microscope, Insect
Aphid populations explode quickly, tend to develop at
growing tips, and can damage young tissue. Select a
bloom friendly option with low bee exposure risk when
treating blooming plants destined for the landscape.
TriStar, Rycar and XXPire are examples of safe and
effective products for use against exploding aphid
populations.

Aphids, Roots – Rudbeckia, Insect
Root aphids can be difficult to control, in part because
detection is often delayed. Always check the roots of
plants showing poor growth, especially if the pattern
is spotty or patchy in a crop. In retail, if the problem
is limited to a handful of plants, dumping the infected
plants is the most effective means of quick control.

Spider Mites

Mandevilla, Spider Mite Damage
Tropical plants, such as mandevilla, are known spider
mite havens. Scout susceptible crops regularly,
especially upon arrival to your store.

When thrips feeding scars are present on a crop, be
sure to scout for both adults (check flowers) and larvae
(check foliage). Pylon TR and TriStar are effective.
Mainspring and XXPire are also bloom-safe options.

Gerbera Daisy, Broad Mite and Thrips
Flower Damage
Thrips can be destructive pests, greatly reducing
salability due to flower damage. White streaking on
blooms indicates thrips presence. Scout affected
plants using a beat test: tap flowers over a piece of
white paper to dislodge thrips, which will be visible on
the paper.
