Aerobic microorganisms
Microbes that can only thrive with a good supply of oxygen
Agriculture
Agriculture primarily involves the growing of field crops such as wheat, oilseed rape, etc.
Anaerobic microorganisms
Microbes that can only thrive without oxygen
Apex (tip of the embryo)
Active growth zone at plant tip(s) |
B
|
|
Beneficial creatures
Organisms that promote productivity in an agricultural system, e.g. earthworms as soil improvers or rove beetles as killers of harmful insects |
C
|
|
Carcinogenic
Substance that can cause cancer
Citrus fruits
Oranges, lemons, limes, grapefruit, mandarins, etc.
CO2
Chemical formula for carbon dioxide
Crop rotation
Periodical cultivation of a field with differing crops in succession

Formulation
The form in which a pesticide is used, e.g. slug pellets contain a bait material incorporating Meta metaldehyde as the active ingredient
Fruit-growing and horticulture
Professional growing of fruit and vegetables and, in some cases, ornamental plants |
H
|
|
H2O
Chemical formula for water
|
I
|
|
Indigenous
Native, of local origin
Integrated Production (IP)
Agricultural production system in which fertilizers and crop protection measures are used only as required. Only pesticides with minimal side effects are employed.
|
L |
| Leguminous plants
Plants of the pea family which, thanks to nodule bacteria, are capable of assimilating nitrogen from the air. Examples of leguminous plants include clover, lupins, beans, peas and lucerne. |
M
|
|
Metaldehyde
Active ingredient of Meta slug pellets. Metaldehyde is the tetramer of acetaldehyde.
Mollusks
Class of invertebrates in the animal kingdom that includes slugs, mussels and squid
Mutagenic
Causing changes in the genes of an organism |
O
|
|
Organic farming
Agricultural production system based primarily on self-regulating biological processes and natural balances. Only a very limited number of auxiliary substances (pesticides, etc) can be used. |
P
|
|
Photolytic
Describing a chemical reaction triggered by light. By contrast, a photolytically stable substance is one that is not affected by the action of light.
Photosynthesis
Formation of sugars from water and CO2 in the plant leaf under the influence of light
Plant residues
Leaf, stem or root material that is left on the field after harvesting |
S
|
|
Secondary fungal infections
Infection of an organism with a fungus that is capable of overcoming the defense system of the host only because the host organism has been weakened by a different pathogen
Selective molluscicide
A slug control preparation that acts exclusively against slugs and does not adversely affect other organisms
Semiarid climate
Zones with low precipitation (not more than 500 mm a year)
|
T
|
|
Teratogenic
