This booklet is a synthesis and a party of a giant physique of agro-ecological examine performed at the administration of the pests of cotton, one of many world�s significant vegetation and one that has traditionally been a really heavy customer of inputs of insecticides. It demonstrates how agro-ecological ways to pest administration are eventually coming near near the �mainstream�, with an expanding acceptance that farmland supplies a variety of atmosphere providers (nature�s items and services), together with yet under no circumstances exclusively comprising the creation of meals.

According to an analysis by the World Bank (23), the spectacular progress achieved in the field of biotechnology The New Issues in Crop Protection 17 applied to industrial agriculture is not easily transferable, given the huge number of small-scale farmers in the developing world, due to inadequate investment in ensuring the expression of the agronomic potential of improved varieties. However, the success of genetically modified cotton among small-scale farmers in China — and now to a similar extent in India — make it clear that it would not be prudent to generalise the conclusions of this analysis and that the diversity of socio-economic and agronomic circumstances should be kept in mind.

To help understand the examples used as illustrations in the following chapters, some general information is given below. 1 COTTON AND ITS CULTIVATION Cotton is a perennial, woody plant exploited as an annual crop by 100 million farmers on 30-35 million hectares in 100 different countries, in tropical and sub-tropical areas characterised as hot/ temperate. Today, production exceeds 25 million tonnes of cotton fibre, up from only 6 to 7 million tonnes in the 1950s from a roughly equal area. Sixty per cent of the total is produced in Asia, mainly in China, India, Pakistan, Uzbekistan and Turkey, 25% is produced in North and South America, especially the USA and Brazil and 10% in Africa, especially in Egypt, Mali, Côte d'Ivoire, Benin, Burkina Faso and Zimbabwe.
