Chemicals that drift out of your yard may travel to other areas and hurt wildlife or plants. The chemicals can wash away into nearby waterways or travel down into the groundwater supply. The weed killer may damage the environment and enter the human food chain and water supply.
What are the disadvantages of using chemicals to control?
Another disadvantage of chemical pesticides is resistance. Pesticides are often effective for only a (short) period on a particular organism. Organisms can become immune to a substance, so they no longer have an effect. These organisms mutate and become resistant.
What is the disadvantage of herbicide?
Herbicides contribute to air, water and soil pollution. It can contaminate the soil and the rainwater can carry these chemicals to other areas which will eventually pollute the waterways. Herbicide-contaminated waters can kill fish and other aquatic life.

What are the advantages of using chemicals to control weeds?
Advantages of Herbicides or Chemical Method of Weed Control
The use of herbicides as pre-plant and pre-emergence treatment can control weeds, before their emergence from the soil so that crop can germinate and grow in weed free environment or with minimum competition during their tender and seedling stage.

| Can help to overcome poverty | Pesticides are not selective enough |
What are disadvantages of weeds?
1. Reduction in crop yield: Weeds compete for water, nutrients & light. Being hardy & vigorous in growth habit, they soon outgrow the crops & consume large amounts of water & nutrients, thus causing heavy losses in yield.The loss of N through weeds is about 150 kg/ha.
What are the disadvantages of insecticides?
Disadvantages of insecticides
Non-target organisms Insecticides can kill more than intended organisms and are risky to humans.Resistance Insects when repeatedly exposed to insecticides build up resistance until finally, they have little or no effect at all.
What are the advantages and disadvantages of using herbicide?
Pros & Cons of Herbicides
- Pro: Crop Yield. Left untended, weeds compete with crops for water, sunlight and nutrients in the soil.
- Pro: Economic Benefits.
- Pro: Beautiful Landscaping.
- Con: Health Effects.
- Con: Increased Resistance.
- Con: Pollution.
What are the disadvantages of using chemicals in agriculture?
Disadvantage: Unsustainable Soil Conditions
Nitrogen is often regarded as a highly effective and cheap fertilizer. However, repeated use of the chemical can cause an imbalance in the pH of the soil, eventually rendering it useless for growth of any kind.
What are the advantages of chemical control?
Chemicals control can bring society and industry various benefits as it makes production and supply chains cleaner and safer, and reduces the risk of costly accidents. It also provides incentives to develop safer chemicals and more resource-efficient and safer production methods.
What are the disadvantages of biological control?
Disadvantages of biological control
Biological control agents are expensive to find. The greatest expense is during the field survey and early testing stage which must be conducted overseas. Suitable agents may not even exist. Potential agents are also expensive to test for specificity.
What are advantages of using chemicals in agriculture?
With the introduction of pesticides, farmers have been able to produce bigger crops on less land, Increasing crop productivity by between 20 and 50 percent. In addition, pesticides allow farmers to maximize the benefits of other valuable agricultural tools, such as high quality seeds, fertilizers and water resources.
What are the advantages of chemicals?
List of the Advantages of Chemical Energy
- Chemical energy can be converted into electrical energy.
- Plants have the energy to grow because of chemical energy.
- It is available in great abundance throughout the world.
- Chemical energy is easy to consume.
- We can store chemical energy so that it can be used in the future.
What are the negative drawbacks of using pesticides?
After countless studies, pesticides have been linked to cancer, Alzheimer’s Disease, ADHD, and even birth defects. Pesticides also have the potential to harm the nervous system, the reproductive system, and the endocrine system.
What problems can weeds cause?
Weeds can cut off your plants food supply
If your plants aren’t getting enough nitrogen, potassium and other nutrients, they become more susceptible to disease and insect infestation. And as weeds suck up nutrients from the soil, this can not only cause plants to wither, it can lead to abnormal fruit growth and color.
Why do weeds cause problem?
They cause problems because they: Rob crops of light, water, and nutrients, Grow faster than crops and crowd them out, Can produce certain chemicals that are toxic to crops or grazing animals.
What are the effects of weeds to plants?
1. Weeds compete with the crop plant for light, nutrients, water, space and other growth requirements and reduce the crop yield. 2. Increase the cost of production by increasing the cost of labour.
What harm is caused by using an excess of chemical insecticides?
Answer: The chemicals can bioaccumulate in the body over time. Exposure effects can range from mild skin irritation to birth defects, tumors, genetic changes, blood and nerve disorders, endocrine disruption, coma or death.

- Cons: Persistence is Varied.
- Pros: Low in Toxicity.
- Cons: Glyphosate Is Still Toxic.
- Pros: Effective Weed Control.
- Cons: Nonselective.
