Best working conditions Ercal

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.

Handling

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.

  • Storage after receipt: 1-2 days
  • Storage temperature: 8-10°C/47-50°F
