There are several insecticides that can be used to control whiteflies, but it is important to note that they can be difficult to control with insecticides. Here are some of the most effective insecticides for whiteflies:
-
Imidacloprid: This is a low toxicity product designed to affect insect neurotransmitters, and it has been proven effective in treating whiteflies.
-
Marathon: This systemic insecticide has been used most frequently over the past few years to control whiteflies.
-
Celero, Flagship, Safari, and TriStar: These are newer chemically related compounds that are also effective against whiteflies.
-
Judo: This is the newest material to be registered for whitefly control, and it has been found to be effective.
-
BotaniGard ES: This is a highly effective biological insecticide containing Beauveria bassiana, an entomopathogenic fungus that attacks a long list of troublesome insects, including whiteflies.
-
Safer Soap: This is a short-lived natural pesticide that works by damaging the outer layer of soft-bodied insect pests, causing dehydration and death within hours. It can be effective on heavy infestations of whiteflies.
-
Multipurpose Insect Killer: This product works immediately and will provide a fast knockdown of all garden pests, including whiteflies. It can be mixed with water to be sprayed as needed.
It is important to note that due to the propensity of whitefly populations to develop resistance, it is essential to scout weekly and develop a Resistance Management Program (RMP) .
