|8. Pest control using insecticides|
In pest control there are two kinds of treatment which complement each other: preventive and curative measures. The preventive measures, which consist above all in suitable storage buildings and the careful observance of all hygiene measures, form the basis of all pest control. Without these, any other measures are bound to be of no effect arid uneconomic. Preventive pest control is described in detail in section 5.2; section 3.3 also contains relevant information.
The most important curative measure in stored-product pest control is the application of chemicals. A distinction is made between insecticides and fumigants (see chapter 9).
The parts of this chapter concerned with the use of insecticides apply only to central storage. section 4.4.3 deals with the application of insecticides in small farm storage. The remaining parts of this chapter are equally relevant for both types of storage.
