The most complex structure of natural product compounds, easily synthesized or synthetic high cost; active ingredients decompose, preparations are complicated and difficult to standardize; most of the efficacy of botanical pesticides are slow, leading some farmers to believe that the use of pesticides has no effect; spraying more often, residual limitation period is short, not easy for farmers to accept; plant collection is seasonal, etc.
These pesticides have toxic effects on humans beings and other animals.

The disadvantage of the botanical in shampoo is that it contains certain chemicals that can react with the human hair.
Yes, insecticides can be made from the leaves of the calamansi [x Citrofortunella microcarpa]. The plant in fact is a popular source of botanical pesticides in its native Philippines. Botanical pesticides are organic pesticides whose ingredients draw on plant parts.
The greatest advantage of pesticides is their ability to eliminate pests. However, pesticides also carry the risk of poisoning beneficial plants and animals. Some forms of pesticides even directly damage the environment.
Biological, botanical, chemical, and mechanical treatments are some of the methods for eliminating annoying pests. They respectively involve natural enemies, organic pesticides, synthetic treatments, and fences, live traps, row covers, and sticky traps.
You can be killing millions of living things, no matter where you spray the pesticide there are several things that die. Certain other insects are on a plant when you apply a pesticide, and that could kill them and the bad insect. When it rains, the pesticides are carried away with the rain, going to the ocean, polluting the ocean and also killing coral. THere are still millions of other disadvantages of using pesticides.
pesticides poison pests, but they can also poison other living organisms, or those who eat poisoned organism etc. also, farmers who don't use pesticides can sell their produce for more money as it is organic.
Organic pesticides are considered more favorable than chemical pesticides. Their ingredients include only animal- and plant-based inputs that are supposed to be ecosystem- and people-friendly. The above-mentioned assumption needs to be checked and revisited since the botanical pesticide rotenone is listed among the controls that harm people, pets and wildlife.

Yes pesticides are some what bad because of what they do, they kill insects. They also go threw the ground and eventually end in water making pollution... Some of the insects that the pesticides kill are actually not going to hurt the plants that the pesticides are on in the first place. that means pesticides kill and pollute, does that sound very good. Pesticides are made from chemicals, bad ones at that and poison's in poison's out.
A pest-killer that contains naturally occurring mineral or plant derivatives describes a botanical pesticide. The pesticides in question also have the synonymous names natural and organic insecticides. An example is the pyrethrum derived from dried flower heads of Chrysanthemum cinerariifolium (Dalmatian chrysanthemum) or of Chrysanthemum coccineum (painted daisy).
Pesticides are used in order to kill insects. If insects get on some types of vegetation, it can kill it.
