Impact on environment

Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

What are the benefits of pesticides in agriculture?

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.

How to reduce pesticide use?

Today there is a consensus among a wide range of stakeholders that pesticide use needs to be gradually reduced to a level that is effectively required to ensure crop production, and that risks of pesticide application need to be reduced as far as possible. Here are listed 7 strategies available for pesticide reduction. 1. Agronomic practices.

Is pesticide reduction a shared goal in United States agriculture?

This enthusiasm of the biotechnology industry might suggest that pesticide reduction is a broadly shared goal in United States agriculture. But is it? Outside of the biotechnology industry trying to promote its products, not many in mainstream agriculture give high priority to pesticide reduction.

Examples of acute health effects include stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death.


What are the harmful effects of pesticides and fertilizers?

Fertilizers and pesticides use has led to the problem of air, water and soil pollution. The nitrous oxide (N 2 O) produced by microbial action on inorganic fertilizers in soil causes depletion of stratospheric ozone layer, which serve as shield against harmful UV-rays emanating from the sun.


How is soil affected by insecticide and pesticide?

Uncontrolled application of pesticides can contaminate soil and may kill other nontarget organisms. Pesticides can damage soil biomass and microorganism such as bacteria, fungi, and earthworms. Microbial biomass is a labile component of soil organic matter and has an important role in soil nutrient element cycle [1].


How can farmers stop using pesticides?

The main way farmers can gain leverage that will allow them to quit the use of pesticides involves new agriculture technology and its adoption pace. Farmers who have sufficient knowledge and capital to invest in new equipment will have the ability to enjoy the benefits of IoT which will acutely increase their crop monitoring abilities. By knowing exactly when a crop is being attacked by fungus, bacteria or viruses, pesticide use can be used when needed rather than used on a continuous basis – this will reduce its potent negative effects. Moreover, the more data we gain by using AgTech on crop health, we will be able to pinpoint and manufacture more eco-friendly solutions that will aid in protecting crops from diseases without negative health effects for humans.


Why do farmers use pesticides?

In order to protect crop health from pests that feed on or infect the plants themselves, farmers tend to use pesticides in order to retain their produce. This helps them prevent potential losses and maximize gains as more crops are produced and thus more are sold in the market.


Why are pesticides used in agriculture?

The biggest reason why using pesticides seems worth it to local farmers is because they are a cost-effective way to do more business if their produce is prone to pests. The reality is, that by “playing it safe” and avoiding the use of pesticides, the financial loss that professional growers will incur due to the loss of produce is far greater than the expenses required to purchase pesticides and prevent that from happening in the first place. On top of that, by actively and continuously making your crops “disease-proof”, the chance of the produce being infected in the future drops significantly.


What are the negative effects of pesticides?

Those who are continuously exposed to pesticides are prone to developing respiratory diseases and serious illness es that include cancer, as some of the chemicals that pesticides consist …


What are the different types of pesticides used in farms?

There are 6 main types of pesticides that are being commonly used in most farms: Insecticides – used to deter insects from feeding on the produce. Herbicides – used to kill malicious plants that damage crops. Rodenticides – chemicals that protect plants from rodents. Bactericides – kills bacteria on the surface (or inside) of the plant.


What is the best way to kill rodents in plants?

Rodenticides – chemicals that protect plants from rodents. Bactericides – kills bacteria on the surface (or inside) of the plant. Fungicides – help plants in areas where they are prone to fungus infections. Larvicides – Used to effectively kill larva in areas where crops are prone to it.


Is pesticide bad for the environment?

Using these chemicals might sound like a great decision for the short-term, however, there are huge long-term disadvantages for using toxic chemicals for the soil on which the produce is grown on. At the end of the day, pesticides are poisons – toxic chemicals that don’t just harm the “malicious bugs” that attack plants, but the consumer, producer (farmer) and the environment as well. Valuable vitamins and minerals that the plants absorb from the soil are being “dissolved” by the pesticides, which causes plant health to deteriorate and produce low-quality gains for the long-run.


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.


What is pesticide?

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Among these, organochlorine (OC) insecticides, used successfully in controlling a number of diseases, such as malaria and typhus, were banned or restricted after …


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 1996, seven pesticides (acephate, chlopyriphos, chlopyriphos-methyl, methamidophos, iprodione, procymidone and chlorothalonil) and two groups of pesticides (benomyl group and maneb group, i.e. dithiocarbamates) were analysed in apples, tomatoes, lettuce, strawberries and grapes.


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 are the high risk groups exposed to pesticides?

The high risk groups exposed to pesticides include production workers, formulators, sprayers, mixers, loaders and agricultural farm workers. During manufacture and formulation, the possibility of hazards may be higher because the processes involved are not risk free. 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.

Should we ban pesticides?

Banning individual pesticides (like neonicotinoids) isn’t the answer. History shows these come too late and are simply replaced with another pesticide. Instead, we need to urgently support farmers to fundamentally change how they farm. This is entirely possible without a reliance on pesticides, as organic farmers worldwide demonstrate. Using these greener farming approaches, known as agroecology, farmers aim to work with nature to create a more balanced system that doesn’t rely on pesticides.
