PREFACE Everyone eats in order to live and so with the pests. Crop protection, therefore essential for humans to study, comprehend, research, apply, extend and produce for he will be able to contribute in answering the problems in crop production and add on to the body of knowledge in agriculture. Crop Protection is stimulating, attention-grabbing, vital, and worth studying in its own right. It is also, however, a science that has a hands-on and upright goal of protecting the food available for humans and animals. Plant pathogens, arthropods, weeds and vertebrate pests by their existence, inhibit the crop growing in some areas or food crops may be grown but plants may attack by them, tear parts or entire field and reduce much of their produce before they can be harvested or consumed. It is predictably estimated that diseases, arthropods, weeds and vertebrate pests together annually interfere with the production of, or destroy, between 31 to 42% of all crops produced worldwide. The losses are usually higher in the developing countries and lower in more developed countries. The necessity for management and control measures to plant pest and diseases limits the total land available for farming each year, limits the kinds of crops that can be grown in fields already contaminated with certain microorganisms and every year we need millions of tons of pesticides for treating seeds, fumigating soils, spraying plants and treatments for postharvest fruits and vegetables. It is therefore the responsibility and goal of crop protectionists to balance all the factors involved so that the maximum amounts of food can be produced with fewest side effects to the people and to the environment.

CHAPTER I II. INTRODUCTION Plants make up the majority of the earth’s living environment as trees, grass, flowers, and so on. Directly or indirectly, plants also make up all the food on which humans and all animals depend. Even the meat, milk, and eggs that we and other carnivores eat come from animals that themselves depend on plants for their food. Plants are the only higher organisms that can convert the energy of sunlight into stored, usable chemical energy in carbohydrates, proteins, and fats. All animals, including humans, depend on these plant substances for survival (Agrios, 2005 ). Note. Pls add on references Plants, whether cultivated or wild, grow and produce well as long as the soil provides them with sufficient nutrients and moisture, sufficient light reaches their leaves, and the temperature remains within a certain “normal” range. Plants, however, also get infected and infested. These plants grow and produce poorly, they exhibit various types of symptoms and damage and often, parts of plants or whole plants die. It is not known whether diseased plants feel pain or discomfort. The agents that cause disease in plants are the same or very similar to those causing disease in humans and animals. It includes pathogenic microorganisms, such as viruses, viroid, bacteria, spiroplasmas, mycoplasmas, fungi, protozoa, and nematodes, and unfavorable environmental conditions, such as lack or excess of nutrients, moisture, and light, and the presence of toxic chemicals in air or soil (Agrios, 2005). Plants also suffer from competition with other, unwanted plants (weeds), and, of course, they are often damaged by attacks of insects. Plant damage caused by insects, humans, or other animals is not usually included in the study of plant pathology. Plant pathology is an integrative science and profession that uses and combines the basic knowledge of botany, mycology, bacteriology, virology, nematology, plant anatomy, plant physiology, genetics, molecular biology and genetic engineering, biochemistry, horticulture, agronomy, tissue culture, soil science, forestry, chemistry, physics, meteorology, and many other branches of science. Crop protection profits from advances in any one of these sciences, and many advances in other sciences have been made in attempts to solve plant pathological problems. As a science, crop protection tries to increase our knowledge about plant diseases and arthropods damage. At the same time, crop protection tries to develop methods, equipment, and materials through which plant diseases and arthropods damage can be avoided or controlled. Uncontrolled plant diseases and arthropod damage may result in less food and higher food prices or in food of poor quality. Diseased plant produce may sometimes be poisonous and unfit for consumption. Some plant diseases may wipe out entire plant species and many affect the beauty and landscape of our environment. Controlling plant disease and arthropod damage result in more food of better quality and a more aesthetically pleasing environment, but consumers must pay for costs of materials, equipment, and labor used to control plant diseases and arthropod damages and, sometimes, for other less evident costs such as contamination of the environment. In the last 100 years, the control of plant diseases and other plant pests has depended increasingly on the extensive use of toxic chemicals (pesticides). Controlling plant diseases and arthropod damages often necessitates the application of such toxic chemicals not only on plants and plant products that we consume, but also into the soil, where many pathogenic microorganisms live and attack the plant roots. Many of these chemicals have been shown to be toxic to nontarget microorganisms and animals and may be toxic to humans. The short- and long-term costs of environmental contamination on human health and welfare caused by our efforts to control plant diseases (and other pests) are difficult to estimate. Much of modern research in plant pathology aims at finding other environmentally friendly means of controlling plant diseases and arthropod damage. The most promising approaches include conventional breeding and genetic engineering of disease-resistant plants, application of disease-suppressing cultural practices, RNA and gene-silencing techniques, of plant defense- promoting, nontoxic substances, and, to some extent, use of biological agents antagonistic to the microorganisms that cause plant disease and arthropod damages. The challenges for crop protection are to reduce food losses while improving food quality and, at the same time, safeguarding our environment. As the world population continues to increase while

arable land and most other natural resources continue to decrease, and as our environment becomes further congested and stressed, the need for controlling plant diseases and arthropod damages effectively and safely will become one of the most basic necessities for feeding the hungry billions of our increasingly overpopulated world.

The healty and well being of the plant plays a major role in crop production. It is, therefore, necessary that the plants must be kept free of any abnormality caused by any factors in its environment. The ultimate goal of applied crop protection is to hold pest populations below their economic threshold level. This can be achieved through application of control measures which may not assure complete success but at least reduce pests population. 1.1. Definition of Terms 1.1.1. Healthy Plant - is a normal plant growth without any disturbance of its physical and physiological growth processes. 1.1.2. Diseases or abnormal Plant Growth - is a plant which growth processes are affected either by insect pests and diseases including its physiological functions either caused by water stress or nutrients deficiency or toxicity. 1.1.3. Crop Protection- is a science of preventive and curative againts pests. Pests are living organisms that compete with man in their needs for food and shelter. The term pest includes all harmful insects, pathogens, birds, rodents, noxious weeds and human. 1.1.4. Integration 1.1.5. Pests 1.1.6. Management 1.1.7. IPM 1.1.8. Equilibrium Position 1.2.
