This kind of control consists in the utilisation of a physical agent in order to modify the physical environment of the pest or disease.
A lot of different options can be found among the physical strategies: tillage, mulching, photoselective covers, etc.
- Utilisation of a hoeing machine between the crop rows to avoid emerging weeds.
- Ploughing with flexible tine harrow to eliminate recently emerging weeds.
- Placing of mulching (plastic, paper, organic materials) in the entire surface (green houses) or around the crop (mainly fruit trees or horticultural crops).
- Placing of black plastic mulching, that avoids the normal proper development of a pest. For example, in the case of asparagus, this technique avoids the bean seed fly laying eggs near the crop.
-Placing meshes in greenhouses’ apertures and covering fruit trees to avoid insects damaging crops. Besides, in horticultural crops, agricultural thermal blankets can contribute to protect against pests.
Implementation of this measure in LIFE AGROintegra project:
Some experiences regarding physical control have been done in the framework of LIFE AGROintegra project. In some horticultural crops (broccoli and green beans) the effect of a hoeing machine in the control of weeds that are between the crop rows.
