Agrochemicals are synthetic elements; used to increase agricultural production in both quantity and quality along different stages of food production chain. Generally they are divided into two major groups. Fertilizers and pesticides, and each group was classified into subgroups according to their nature, purposes and use, whether they are mixed or complex. 1.1.1 Fertilizers Fertilizers provide plants with the food they need for their growth and development. Their occurrence can be either naturally inform of free nutrients or industrially manufactured product in form of mixed or complex fertilizers, which contain more than one of the primary plant nutrients produced by a process of chemical reaction. 1.1.1.1 Fertilizers classification Plants require practically 92 natural elements for their growth. But 16 out of these are the most important for good growth, and 13 out of 16 are highly essential mineral nutrient elements, which must be supplemented to the plant by mineral fertilizers. Accordingly fertilizers can be classified as follows: (cid:190) Primary Plant Nutrients These are nitrogen, phosphorous and potassium, which are required by plants in large amounts. (cid:190) Secondary Nutrients These are calcium, magnesium and sulphur, which are needed, in smaller, but still appreciable quantities (cid:190) Micro Nutrients These are boron, chlorine, copper, iron, manganese, molybdenum and zinc 1.1.2 Pesticides Pesticide is a poison used to kill a plant or animal which some humans consider a pest. It is also used to prevent, control, and destroy and to reduce the number of the pests. 1.1.2.1 Classification of Pesticides Crop protection agents use different methods for classifying the pesticides, but generally the following classification is the most common: (cid:190) Targeted pest whether it is insecticide, herbicide fungicide etc. (cid:190) Effect of active ingredient on the pest that is wide spectrum compounds, selective compounds… etc. (cid:190) According to the residual period whether it is a long residual effect or short period. (cid:190) According to the effect on the pest physiology (cid:190) According to chemical compounds whether it is organic or inorganic (cid:190) According to the speed of the poisoning whether it is fast or slow (cid:190) Degree of the toxicity on the pesticide users, high toxicity low or non toxic etc The physical and chemical properties of the compound processing that is concentrated, emulsphier, dust, powder etc 1.2 Why we use agrochemicals? 1.2.1 Historical Background. 1.2.2 Agrochemicals have been put in use for a long time period and developed according to the people need in the context of quality, quantity and method of use. Pesticides have been used in china before five thousand years. Since then their use increased gradually till the end of the first millennium when inorganic pesticides became widely used. At the end of the nineteenth (19th) century, organic pesticides were discovered. The pesticides industry started during the Second World War and production expanded during the sixties to meet the requirements of the green revolution in the third world countries. From that time till now there is a tremendous increase in agrochemicals production coupled with advanced technology in processing, manufacturing and usage 1.2.2 Rationalization of Fertilizers Use World population will probably peak at some 8000 million around 2030, when two out of every three people will live in towns and cities. Rising income will create a disproportional higher demand for food, meaning over the three next decades food production will need to increase by about 60%. Nearly all of the increase in production will have to come from developing countries through the intensification of agriculture, that is more yields per unit time and per unit area. L.O. Fresco FAO (2003). Fertilizer is known to be a powerful input enhancing production. Indeed, one third of the increase in cereal production worldwide and 50% of the increase in India’s grain production has been attributed to fertilizers. FAO estimated that fertilizers are expected to contribute over 50% of the vertical increase in food and agricultural production. 1.2.3 Economics of Pesticides Usage Pesticides are playing an important role in reducing pre and post harvest losses, which are estimated to be around 50% FAO (1967), 14% out of these losses are due to insects, 14% due to store pests, 12% due to plant disease and 10% due to weeds. The annual global losses are estimated to be from 70 to 240 billon USD (considering only crops) and it was found that the cost of one USD incurred in pest control could result in yield increases by five USD, Yahia (1994). Most of the studies held on the research and mass production scale confirmed the fact that pests and diseases can reduce the yield by 70% if they are not well controlled. It was found that 100 jassides/100 leaves in cotton crop can cause a reduction of 2-3 kantar /feddan, 17 white fly per one cotton’s leaf can reduce the yield by 60% and the African Bollworm can cause a total loss of the whole crop if not controlled. 1.3 Agrochemicals Outlook 1.3.1 International Market In the recent years the international market reflected a tremendous increase in the production, consumption and trading of agrochemical, that is, the market reached the maturity stage. Marketing activities in the global system vary from country to another depending on political, social, economical natural and technological factors, which resulted in integrated marketing system contributing to a collective movement in the direction of sustainable development 1.3.2 World Production The main fertilizers raw materials are hydrocarbons and ammonia feed stock (today mostly natural gas), phosphate rock, sulphur and potassium salts. The total world production was found to be 142 million MT in 2000/2001. China is a leading producing country with 29.2 million MT. In 1996/97 developing countries all share in world total was 43% with annual growth rate 4.5% while all developed countries share was found to be 57% with annual growth rate 2.3% for the same year, (FAO, 2001) Figure (1,1) shows total world Fertilizer production.

The present world production of pesticides is about 2.6 million tones of active ingredients. 1.3.3 World Consumption From 1989 to 1993/94 world fertilizer consumption decreased but started increasing in 1994/95 onwards. In 1996/97-world fertilizer consumption continued to rise from 131.3 million tones to 135.1 million tones, an increase of 2.9%. Fertilizer consumption increased in developed and developing countries by 1.9% and 3.6% respectively for the same year. In 2000/2001 the total world fertilizer consumption was 136.4 million tones, China was a leading fertilizer consuming country 34.6 million MT followed by USA 18.5 million MT, Ireland is the most intensive fertilizer using country in arable land and permanent crops 594 kg/ha although the world average is 91 kg/ha. Cost Rica is most intensive fertilizer-using country in arable land 884kg/ha compared with international average, 100kg/ha (FAO, 2001). Meanwhile the average consumption of chemical fertilizers in Africa is only 5kg/ha. Fig. 2 shows the total world consumption Fig. 1.2 Word Fertilizer Consumption In Million MT 160 140 137 138 141 136 120 100 81 83 85 82 80 60 40 33 33 33 33 23 22 22 22 20 0 1997/98 1998/99 1999/00 2000/01 Nitrogen Phosphate(P205) Potash (N+P205+K205) Pesticides are a capital-intensive industry, used all over the world. About 80% of the total world pesticide production is currently used by developing countries. Africa consumes 5% of the total world pesticide production, 3% out of these 5% consumed by South Africa, 1% consumed by North Africa and the remaining 1% consumed by Africa south of Sahara. 1.3.4 World Trade Most countries increasingly trade agrochemicals. Therefore the international trade is an important part of the agrochemical business. About 57 million tones of fertilizer were traded in 1996/97 for an estimated value of approximately US$ 14 billion. USA is the largest fertilizer importing country in the world 14.02million MT, while Canada is a leading fertilizer exporting country 10.07 million MT. in 2000/01 the total world exports and imports of fertilizers were found to be 60.2 million MT and 63.7 million MT respectively, while total world supply was 136.4 million MT for the same year (FAO, 2001).
