Plant damage caused by vapors released when heating (plastic) materials


Use of materials in the greenhouse can lead to the emission of harmful fumes. Plastics and paint in particular can release vapors after heating. Damage occurs mainly after installation of new materials, in winter with little ventilation, when the plants are relatively weak. In order to estimate the likelihood of damage before use by growers, a test method has been developed to test materials for the release of plant-harmful substances. 




- Testing materials prior to use; 

- Testing materials that are the cause of visible damage in the greenhouse 



The test consists of exposing plants to vapors of the specific material. 


- home-grown plant material (cucumber, Chinese cabbage, kohlrabi) to have the same quality year-round; 

- test for 16 days during which heated air is blown by the relevant material at the plants. Quality and growth of plants is compared with a control;

- reporting the test to the supplier / manufacturer;

- Delivery approval code for placement on the relevant material.


- test facilities available to test materials for vapor delivery;

- inspection report available for supplier / manufacturer;

- Damage to vapors in greenhouses is kept to a minimum.
