Description of practice

Physical pest control is a method of removing insects and small rodents by trapping, setting up barriers or kaolin sprays to prevent further crop damage. It also includes controlling pests before plants are sown.

Insect traps

Coloured traps emitting pheromones are set up in agricultural fields to attract and kill flying insect pests. These traps are intended to provide an effective replacement for expensive insecticides.

Tree bufferzone

Indigenous trees are used to create a buffer zone between fields, preventing the spread of diseases. The trees also enhance the biodiversity of the area.

Kaolin spray

Kaolin (a clay mineral) is sprayed onto tree and vegetable crops. The spray leaves a particle film that protects from pests and environmental stresses.

Nets and nethouses

Nets are used in fruit cultivation to protect against birds. A net house is a structure that is enclosed by a nylon net (like a mosquito net) protecting vegetables from insects and damage by rainfall, wind and sunlight.

Temporary inundation

Bulb fields are temporarily inundated to clear the soil of nematodes, weeds and bulb residues. Inundation reduces the use of chemical pesticides and the submerged plots are popular with birds attracted by mosquito larvae, worms, and water fleas.
