Q: What treatments would you recommend for controlling fungus gnats, thrips and whiteflies?

A: Combating ornamental pests is crucial to ensure important crops such as poinsettias, pansies, and chrysanthemums remain healthy and ready for the season. Growers need to have a successful preventive program in place to best control insect pests.

We recommend the following for fungus gnats:

Safari®: Long residual drench (six weeks)

Gnatrol®: Drench the soil area

Distance® IGR: Excellent control product

We recommend the following for thrips:

TriStar®: Use as a translaminar on adults

Safari®: Long residual drench (six weeks)

Overture®: Excellent on thrips, different mode of action

We recommend the following for whiteflies:

Safari®: Controls Q- and B-biotypes, drench for residual

Menace®: Spray only on adults, no phytotoxicity problems

Distance® IGR: Good on immatures, drench or spray

TriStar®: Spray only as translaminar, rotate with Safari
