Use En-Strip for biological control of greenhouse whiteflies (Trialeurodes vaporariorum) and tobacco whiteflies (Bemisia tabaci) in the third and fourth larval stage. Use En-Strip preventively and at the first sign of pest presence.
How does En-Strip work?
Female adult parasitic wasps parasitize the third and fourth larval stage of the whitefly. Additionally, host feeding also occurs.
How to use En-Strip
Open package carefully inside the greenhouse
Bend and tear off the strips opposite from the mounting hole.
Suspend the cards in the crop, if possible approximately 75 cm under the plant head.
Avoid direct sunlight
Do not touch the pupae
Best working conditions En-Strip
Optimal working conditions for En-Strip require a minimum 24 hour average greenhouse temperature of at least 17°C/63°F. At lower temperatures it is recommended to use the cards with half the amount of pupae.
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store En-Strip, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer and/or under different conditions than recommended.
