Question

Is there a real solution out there for whiteflies? I've been fighting them in the greenhouse for several years.

Asked by Cecelia

They obviously hide enough eggs, etc. to survive no matter how many different soaps, so-called good bugs and chemicals I throw at them. If anything says it eliminates whitefly, I buy it.

Whiteflies are a terrible nuisance and, in large numbers, a major pest.

The best product I have used is called TriStar (Cleary Chemical Corp.).

  • It utilizes three modes of action: systemic, contact, and ingestion.
  • TriStar is a neonicotinyl foliar insect spray for greenhouse, field, nursery and landscape crops.

The label covers broad spectrum control of aphids, mealy bugs, caterpillars, scales, whiteflies, thrips, leaf eating beetles and leaf miners.
