Table explanation
This table contains data on the use of biological control agents in horticultural crops under cover. Except about the number of companies which apply biological control agents and the corresponding area, the table gives information about the number of macrobial organisms, as a total and per group of organisms and per ha. A selection can be made by crop.
Microbial pesticides (like bacteria, fungi) are not is this table because they are plant protection products.
Data available from: 2012
Status of the figures:
The figures of 2012, 2016 en 2020 are definitive.
Changes as of 10 January 2023:
For the subject use of biological control agents the datatype is adapted, because this gave undesirable round numbers. The structure of the table is not changed.
Changes as of 28 December 2022:
Provisional figures 2020 are replaced by definitive figures.
Changes as of 19 July 2022:
None, this is a new table. This table is the processor of the table Biological control in horticulture under cover 2012-2016, see paragraph 3.
When will new figures be published?
New figures over 2024 will become available in December 2025.
Description topics
- Biological control
- Biological control implies the deployment of purchased biological control agents for prevention and control of plagues. A biological control agent is a natural enemy of a plague. The agent is an invertebrate macrobial
- Area size with deployment of macrobials
- Size of area with deployment of macrobiological control agents.
- Area size with deployment of macrobials
- Size of area with deployment of macrobiological control agents.
- Area size with deployment of macrobials
- Size of area with deployment of macrobiological control agents, as percentage of the size area of the crop. In case of 100% each hectare of the crop is treated with at least one macrobial.
- Deployed macrobiological control agents
- The number of deployed macrobiological control agents against plagues. Numbers of macrobials from bankerplants are not included. Numbers of macrobials from sachets with guaranteed outflow are included. Nutrition for predators is not included. Notice that the number of nematodes is very large and therefore a total is only provided for the level of biological groups or macrobial organism.
- Deployed biological control agents per
- Numbers of deployed, purchased, macrobial control agents against plagues. Per hectare. Growth of the population during crop growth is neglected.
- Crop area
- Numbers of deployed, purchased, macrobial control agents against plagues. Per hectare of a crop. This number depends also on the number of cultivations of the crop.
- Area with biological control agents
- Numbers of deployed, purchased, macrobial control agents against plagues. Per hectare of a crop with deployment of at least one macrobial. This number depends also on the number of cultivations of the crop.
