What are the primary benefits of pesticides?

The primary benefits are the consequences of the pesticides’ effects – the direct gains expected from their use. For example the effect of killing caterpillars feeding on the crop brings the primary benefit of higher yields and better quality of cabbage. The three main effects result in 26 primary benefits ranging from protection of recreational turf to saved human lives. The secondary benefits are the less immediate or less obvious benefits that result from the primary benefits. They may be subtle, less intuitively obvious, or of longer term. It follows that for secondary benefits it is therefore more difficult to establish cause and effect, but nevertheless they can be powerful justifications for pesticide use. For example the higher cabbage yield might bring additional revenue that could be put towards children’s education or medical care, leading to a healthier, better educated population. There are various secondary benefits identified, ranging from fitter people to conserved biodiversity.


What is the pesticide use in India?

The pattern of pesticide usage in India is different from that for the world in general. As can be seen in Figure 1, in India 76% of the pesticide used is insecticide, as against 44% globally (Mathur, 1999). The use of herbicides and fungicides is correspondingly less heavy. The main use of pesticides in India is for cotton crops (45%), followed by paddy and wheat.


How do pesticides help the Indian economy?

This result has been achieved by the use of high-yield varieties of seeds, advanced irrigation technologies and agricultural chemicals (Employment Information: Indian Labour Statistics, 1994). Similarly outputs and productivity have increased dramatically in most countries, for example wheat yields in the United Kingdom, corn yields in the USA. Increases in productivity have been due to several factors including use of fertiliser, better varieties and use of machinery. Pesticides have been an integral part of the process by reducing losses from the weeds, diseases and insect pests that can markedly reduce the amount of harvestable produce. Warren (1998) also drew attention to the spectacular increases in crop yields in the United States in the twentieth century. Webster et al.(1999) stated that “considerable economic losses” would be suffered without pesticide use and quantified the significant increases in yield and economic margin that result from pesticide use. Moreover, in the environment most pesticides undergo photochemical transformation to produce metabolites which are relatively non-toxic to both human beings and the environment (Kole et al., 1999).


How many pesticides were used in 1996?

In industrial settings, workers are at increased risk since they handle various toxic chemicals including pesticides, raw materials, toxic solvents and inert carriers.


Why is prevention of adverse health effects and promotion of health profitable investments for employers and employees?

There is a need to convey the message that prevention of adverse health effects and promotion of health are profitable investments for employers and employees as a support to a sustainable development of economics. To sum up, based on our limited knowledge of direct and/or inferential information, the domain of pesticides illustrates a certain ambiguity in situations in which people are undergoing life-long exposure. There is thus every reason to develop health education packages based on knowledge, aptitude and practices and to disseminate them within the community in order to minimise human exposure to pesticides.

How does the dominant agricultural model affect the natural environment?

The dominant agricultural model has increased the chemical burden on natural environment (140, 142). Moreover, international agrochemical companies absorb traditional agricultural companies, leading to an industrialized agriculture model and leaving the local farmers and small producers to face the consequences (138, 143). In many cases, these people are obliged to adopt environmentally unfriendly techniques to increase their production in order to survive in the market, causing more environmental degradation (138). However, due to the fact that food sovereignty does not necessarily mean pesticide-free, organic food production, and because it does not determine pesticide use levels, for this reason, international eco-friendly standards should be implemented. People must be free to decide the method of production of their own food, and an important component of this decision concerns agrochemical products. The decision of the people of Mals to reject pesticides can be considered a step in this direction.


How does food sovereignty affect the environment?

Food sovereignty promotes social, economic, and environmental sustainability , for instance, through the protection of the indigenous population and the production of food for distribution in local markets, and there is an ongoing effort for its recognition as a basic human right (138–140, 142, 145).


What are the factors that determine the health outcome of pesticides?

The type of pesticide, the duration and route of exposure, and the individual health status (e.g., nutritional deficiencies and healthy/damaged skin) are determining factors in the possible health outcome. Within a human or animal body, pesticides may be metabolized, excreted, stored, or bioaccumulated in body fat (1, 2, 13).


Why is pesticide important?

The need for protection against pests is a given and has its roots in antiquity, when both organic and chemical substances were applied as pesticides (146). Since then, numerous chemical pesticides have been produced, and now multinational agrochemical companies, which mostly control global food production, apply new chemical substances with pesticide properties and implement biotechnological advances, thus diverging from traditional agricultural methods. Furthermore, current agricultural practices are based on the wide use of chemical pesticides that have been associated with negative impacts on human health, wildlife, and natural environment (9, 11, 120, 147, 148).


How does industrialization affect agriculture?

The industrialization of agriculture has brought a series of problems including economic, social, and environmental impacts that local populations cannot manage. Furthermore, the overproduction of food, export-oriented monocultures, the demand for cheap labor, and the other characteristics of industrialization have clearly failed to solve the problems of hunger and malnutrition. On the contrary, inequitable food distribution, overexploitation of land and water sources, the overuse of agrochemicals, and the degradation of the natural environment are some of the results of the dominant agricultural model (138, 142–144). Food sovereignty promotes social, economic, and environmental sustainability, for instance, through the protection of the indigenous population and the production of food for distribution in local markets, and there is an ongoing effort for its recognition as a basic human right (138–140, 142, 145).


Why do farmers use pesticides?

Conclusion: Farmers (both conventional and organic) must use pesticides in order to produce enough food to feed the world. Pesticide use peaked in the 1980’s and will continue to decline as farmers and scientists develop new and more effective methods.


Why are pesticides so toxic?

Glyphosate (the most popular herbicide in agriculture) is the least toxic agro-chemical on the list. This is one of the reasons farmers have used it so much instead of other chemicals over the years. Another reason is because glyphosate resistant plants (GMOs) were developed so that farmers could control weeds post emergence with a safer chemical like glyphosate. Household items more toxic than glyphosate include baking soda, table salt, Tylenol, and caffeine.


Why did pesticides decrease?

Reasons for the initial rise include no-till agriculture, herbicide resistant crops, and crops like corn and soybeans being planted over more acres. Reasons for the decline include more effective pesticides, better application technology, genetic engineering (GMOs) and new production methods like cover crops. (This is further explained in Part 2)


Why is glyphosate considered a safer chemical?

This is another reason glyphosate is considered a safer chemical, because it is a herbicide. Over the last 50 years, the use of safer herbicides has risen while the use of insecticides and fungicides has declined.

Is glyphosate safe for plants?

However, research on Canada, United States, and Sweden found the chemical to be a possible carcinogen. Glyphosate was generally thought to be safe because of its low toxicity on environment.


Is parathion a cancerous pesticide?

Many pests that hinder the crops and plantation start to fade while these vegetation continue to flourish. Yet, despite its successful and effective , recent study found that parathion has the possibility to be cancerous to human. Human exposed to it may start to get their cells degenerate quicker than normal pace. Thus it is dangerous to be around one.
