Unlike DDT and other chlorine-based insecticides, the newer chemicals
are not stored in fat tissue; they are soluble in water, Animals can remove
them from their bodies by breaking them down in their livers and
excreting them. They can also be broken down within the soil, These new
compounds operate like nerve gases, which act by preventing electrical
messages from travelling from the brain to the muscles that control
breathing or the limbs, This either kills the animal directly or makes it
vulnerable to predators.
Although somewhat safer than the older chemicals, the newer
insecticides are not without their problems. First, they break down quicldy
in the soil, and so must be applied to crops more often. Second, these new
chemicals are not selective. Because the nerve action of most larger
animals is very similar, these insecticides are capable of killing mammals,
birds, reptiles, amphibians, and fish. Unintended changes to the food web
are difficult to predict. Third, animals that have died or been weakened by
the toxin put any other animal that eats them at risk through
bioamplification. Large dosages of the toxin can still cause death.
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
Zebra mussels reproduce rapidly due to high fecundity rates and lack of natural predators in new ecosystems. Garlic mustard possesses allelopathic compounds that inhibit the growth of other plant species, giving it a competitive advantage and allowing it to spread quickly in new environments.
Recycling paper is better than composting it because paper can be recycled multiple times without losing quality, while composting paper requires more energy and resources to break down the material. Additionally, recycling paper helps to save trees and reduce the need for new paper production, which can have a significant environmental impact.
Substitution reactions are commonly used in organic chemistry for the modification of functional groups on molecules. They are often utilized in the synthesis of new compounds, as well as in pharmaceutical and agrochemical industries to create new drugs or pesticides. Substitution reactions are also important in biochemistry for understanding enzyme mechanisms and metabolic pathways.
They produce chemicals in the form of pesticides, herbicides, fungicides and insecticides to better target weeds, different fungal diseases and insects that would decrease production value of a crop. They can also measure and analyze nutrient content of different feeds, analyze blood, urine and fecal tests for any parasites or diseases, and, as a part of a team of food scientists, create different food for people.
DDT cannot be used in New Zealand. New Zealand has signed and ratified the Stockholm Convention on Persistent Organic Pollutants which includes DDT. DDT was prohibited from use on New Zealand farmland in 1970, and its production and sale for all other purposes was banned by law in 1989.
Using the new pesticide produces bigger tomatoes than using the old pesticide. -Apex

We made DDT for the War Effort.
new things are better than old depending on what your talking about.
new york is way better than paris.
New Moon was way better than Avatar.
DDT is a pesticide that was used in the past to control insects and to prevent them from damaging crops. The problem with DDT is that it accumulates in the environment and remains in the muscles of animals and fish. When birds consume too much DDT, such as by eating fish, they are unable to make hard shells on their eggs, resulting in very few new babies being born in certain bird populations, such as pelicans.
no
today's life is better than before as new inventions are done there are new technology and discovery
That depends on personal opinion. If you think Twilight is better than New Moon, or if you think New Moon is better than Twilight, that is your own opinion.
