Use Ercal for biological control of greenhouse whitefly (Trialeurodes vaporariorum) and tobacco whitefly (Bemisia tabaci) in the second and third larval stage. Use Ercal preventatively and at the first sign of pest presence.
Adult female parasitic wasps parasitize the second and third larval stage of the whitefly. Additionally, host feeding also occurs.
Optimal working conditions for Ercal require a minimum of 24 hour average greenhouse temperature of at least 20°C/68°F. However, successful introduction is possible at lower temperatures. Eretmocerus eremicus also stays active at temperatures above 30°C/86°F.
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 Ercal, 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.
