Only use products that are permitted in your country / state and crop. Check local registration requirements.
Environmental conditions:
High relative humidities give better effects. The night temperature has to be above 16 degrees Celsius / 61 degrees Fahrenheit for oviposition.
Storage and handling:
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Storing them for a period can have a negative impact on their quality and is only possible under the conditions described below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.
