What are the disadvantages of chemical pesticides?
On the other hand, the disadvantages to widespread pesticide use are significant. They include domestic animal contaminations and deaths, loss of natural antagonists to pests, pesticide resistance, Honeybee and pollination decline, losses to adjacent crops, fishery and bird losses, and contamination of groundwater.
What are the dangers of using pesticides?
Any harmful effects that occur from small doses repeated over a period of time are termed “chronic effects.” Suspected chronic effects from exposure to certain pesticides include birth defects, toxicity to a fetus, production of benign or malignant tumors, genetic changes, blood disorders, nerve disorders, endocrine …
How do pesticides affect plant growth?
Pesticides may impact the crop physiology through various disruptions, such as perturbation in the development of the reproductive organs, growth reduction, and alteration of the carbon and/or nitrogen metabolism, leading to a lower nutrient availability for plant growth.
What is a bad effect of spraying pesticides on crops apex?
-1- It affects the animals and aquatic life. Some pesticides wash away with rain and flow into water bodies. -2- It kills some useful microorganisms/ decomposers in soil.

Are pesticides harmful to plants?
When used properly, pesticides can protect your plants or home from damage. However, when the label instructions are not followed correctly, plant injury may occur, pests may not be controlled, health may be impaired, and pesticides may contribute to soil, air, or water pollution.
Can pesticides damage plants?
They certainly can be. Insecticide plant injury, or actually any kind of chemical plant injury, is known as phytotoxicity. Herbaceous plants are most vulnerable to pesticides. Woody plants tolerate them better, but new fresh growth can be damaged by these chemicals.
What is the effect of chemical spray?
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.
Why is the spraying of pesticides harmful to US Class 8?
pesticides are poisons that are poisonous to animals and both humans. herbicides will not affect humans or other animals. However, other pesticides are not as selective, and can be harmful to other organisms such as butterflies or humans.
What are the negative effects of pesticides?
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.
Can secondary benefits be justifications for pesticide use?
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.
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.
What are the effects of killing caterpillars on the crop?
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.
