Integrated crop protection

from Wikipedia, the free encyclopedia
The ladybird, a scavenger predator, feeds on aphids, scale insects, thrips, and egg larvae on insects. The mycelium of the powdery mildew is also consumed as food. The ladybug does not manage to reduce the fungus sufficiently.

The Integrated pest management is considered as a model of practical pest management . It comprises systems in which all economically, ecologically and toxicologically suitable processes are used in the best possible way in order to keep harmful organisms below the economic damage threshold, whereby the conscious use of natural limiting factors is in the foreground.

Section 2 of the Plant Protection Act defines integrated plant protection as a combination of processes in which the use of chemical plant protection products is limited to the necessary extent, taking priority into account biological, biotechnical, plant breeding and cultivation and cultural measures . According to Section 2a, good professional practice in the implementation of plant protection measures includes taking integrated plant protection into account. It has been a compulsory part of the advanced training for the certificate of competence in plant protection since 2013.

Integrated pest management begins with the selection of the suitable location for the crop , the correct soil cultivation, the selection of the suitable seed or planting date, the use of healthy seeds or plant material of a variety that is as resistant as possible to the predominant harmful organisms, and a balanced organic variety or mineral fertilization. A crop rotation as varied as possible should be adhered to. Targeted chemical plant protection measures should, if possible, be carried out taking into account the appropriate control thresholds or damage thresholds or relevant forecasting methods.

In the context of integrated pest management, biological pest management can also play a role. It encompasses the human-controlled use of organisms (including viruses) and their services to protect plants from exposure to biotic or abiotic factors. Examples are the use of beneficial insects, i. H. Predators or parasites against animal pests (e.g. parasitic wasps against European corn borer ) or antagonists against fungal pathogens ( e.g. Coniothyrium minitans against S. sclerotiorum, the pathogen that causes white rot on oilseed rape ).
