Effects of Excessive Pesticide on Agriculture
What is the goal of agriculture? Mainly, it is to produce healthy food, affordable for consumers to purchase, while ensuring that farmers are able to earn a decent income. Recently, with greater environmental awareness in society in general, it is also now very important to protect the agricultural environment. This is a big challenge for farmers as they must still obtain reasonable yields and produce quality produce in order to meet the demands of the market. Both these can be severely affected by harmful organisms, commonly referred to as pests (weeds, disease, etc.) that compete against, infect or damage the cultivated crop in a detrimental manner. The most economic and effective way to handle these has been to employ pesticides, many of which are now composed of synthetic chemicals, and it is these substances - very beneficial from the economic and production aspects of farming - which can pose risks to human health and the environment if not properly used. Pest problems are not new; in fact, they have been around as long as agriculture itself. But the pest pressure faced by farmers is now as great as it ever was: the world's fast-growing human population needs to be fed from an always shrinking base of agricul
2. Check labels of products to be mixed to make sure that there are no explicit restrictions against mixing with other chemicals. All pesticides should be stored under lock and key, outside the home. Storage facilities should be well-ventilated and well-lit. Pesticide storage areas should be located away from water sources such as ponds or wells. However, a supply of clean water for decontamination is recommended. Non-porous materials are recommended for flooring and shelving. It is important to locate materials in the storage site so cross-contamination does not occur. Do not store pesticides with food, feed, seed or fertilizer. An emergency ? Subchronic effects are generally limited to very high doses when compared to the exposure levels humans may face in the environment. Examples of bioherbicides that have been registered for weed control are DEVINER, a liquid formulation of Phytophthora palmivora that was registered in 1981 for control of Drift and Volatility of Herbicides - Drift can be a problem with any pesticide; however, drift of herbicides is the most commonly encountered cause of pesticide damage to susceptible crops. No pesticide can be applied by either aerial or ground- equipment without some drift. Spray drift is influenced by air movement, droplet size, and distance traveled by spray before reaching the target area. For minimum drift, application should be made as close to the ground as possible, when air movement is at a minimum, and using spray nozzles which eliminate fine droplets. In some instances, spray additives or thickeners may be used to improve application to the target area and to reduce drift. ? protects people and animals from accidental exposure;
