Biopesticides are naturally occurring biological chemicals that kill pests to achieve a better crop yield.

The bacterium bacillus subtills which is comm Nowadays two-third of the world population is dependent on agriculture and to keep this process at the best condition we need to avoid any pests that might hurt our crops and the best solutions technology have created are the biopesticides.

Biopesticides are biological pesticides obtained from various organisms which include plants, bacteria, fungi , and nematodes.

You may find them similar to chemical pesticides in the way of application and the way they are used but these pesticides achieve better pest management results in an environmental friendly way.

Compared to chemical pesticides biopesticides have a slow action rate and unlike the chemical pesticides, they require a high specificity so they are unable to kill any unrecognized pest.

There are around 299 active ingredients that have the properties of biopesticides in which the canola oil and baking soda are also included.

Biopesticides are the most preferable pesticides since they have the least polluting ingredients.

Plants make up their own natural biopesticides by producing chemicals that kill any pests present on its leaves.

What makes those pesticides great is that only small amounts are required and since they break down rapidly there is no polluting of the environment.

You might ask yourself if these pesticides are that great why is  not all the farmers just throw away the chemical ones and shift toward the biological ones, wow the answer of this question is limited cause Many farmers just still believe that chemical ones are more efficient and they are not used to the Idea of using natural ingredients.

Chapter one: What are biopesticides

Biopesticides fall into three major classes

anly used to fight botrytis is the most widely used biopesticide in the world.

Biopesticides are biodegradable and eco-friendly to the environment.

Biopesticides are 100 % natural and can be made up from many different natural things which include fungus, bacteria and many kind of plants.

You need to apply biopesticides in small amounts because they are highly active and they can work effectively in small amounts.

There are around 1400 registered biopesticides which is a large number compared to the chemical pesticides.

In order for these pesticides to work effectively, You need to apply them specifically, which means there is a certain bio pestcides for every pest present on the plant.


Chapter two: Classes of biopesticides

1, Biochemical pesticides

A Biochemical pesticide is a naturally occurring non-toxic pesticide in which it uses a natural mechanism to inhibit the growth of pests inside a plant.

The four groups that are widely used biochemical pesticides that you can find on the market easily are pyrethrum, rotenone, neem oil ,and various essential oils.

biochemical pesticides use a natural mechanism to manage the growth of pests, for instance, insect sex pheromones which are also biochemical pesticides use substances that interfere with the mating process of the insects and limit their growth.

These kind of pesticides are considered safer and better to the environment due to their fast decomposing property in which they rapidly decompose to the soil as soon as they are putted into it.

These pesticides are also extremely non – toxic and inactivate or kills the pest by using a natural mechanism which is considered the best solution for sensitive or small quantity crops.


2, Microbial pesticides 

They consist of naturally occurring bacteria, viruses, fungi as an active ingredients to fight pests.

Microbial pesticides can control d/t kinds of pests, but however, they are highly selective and unlike their chemical counterparts they don’t kill all the pests present on the plant as the chemical pesticides eliminate all the pests that are present in the plant which may result the absence beneficial pests.

Because they use only natural substances they are less toxic than their chemical-based pesticides.

there are many kinds Microbial pesticides but I tried to list the common ones below.


Bacterial Biopesticides

Account more than 74% of the total microbial pesticides present in the world.

Bacterial biopesticides are the most widely used form of microbial pesticides in which they have many functions.

They are mostly used as insecticides however in small amounts they are used u to control the growth of plant pathogenic bacteria and fungi.

As an insecticide, they mostly target some individual species of moths and butterflies and mosquitoes.

For best results, they must be contacted with the target pest and ingestion inside the plant may b required.

Fungal pesticides

Account more than 10% of the total microbial pesticides present in the world.

Fungal biopesticides are used to control
pests and plant diseases including other fungi,
bacteria, nematodes, and weeds.

Unlike the bacterial biopestIcides they don’t need to be injected inside the plant to be effective you can simply put them on the plant and they will start working.

However ,they need certain type of environmental conditions in order work effectively.

These kind of pesticides are extremely eco-friendly and they have many benefits to the environment.

Viral biopesticides

Account more than 5% of the total microbial pesticides present in the world.

As with the bacterial and fungal ones these kind of biopesticides play a big role in managing crops of different kinds.

They mostly eliminate the bacteria that cause plant disease by infecting its cell wall.

They are very environmental friendly and they don’ t have any side effects on the crops after application.


3, Plant incoprporated pesticides

Plant incorporated pesticides contain biopesticidal substances that are produced by plants and the genetic material needed in order for the plant to produce the substance.

In this kind of biopesticides genes are inserted inside the plant so that the plant can produce its own pesticide naturally and next time pest attack the plant it will have the ability to it automatically without the help of any external body.

after extensive research and numerous findings and Since it doesn’t have no risk to human health or the environment when applied the EPA registered it officially as a pesticides in 1995 so you can find some of the best plant – incoprated pesticides on the market.


Chapter Three: Advantages of biopesticides

As an expert in agriculture, I want to tell you that biopesticides are the best pesticide products you can ever use in farming.

Biopesticides are with many advantages and they have dominated their counterpart the chemical ones,

But we tried to list out some points why biopesticides are considered the most desired option in farming.

1, high specificity

Biopesticides gives us the ability to select the one or two kinds of pest species we want to eliminate without hurting the other beneficial pests which may result in a better crop yield.

and Unlike the chemical pesticides they don’t destroy all the organisms or pests present on the plant but what they really does is just killing the target species which are specifically applied to eliminate.

2, less pollution

Biopesticides are made up from 100% natural ingredients which are much less polluting than most of the chemical pesticides that contain very toxic ingredients which are very harmful for both the human health & environment.

Since biopesticides decompose rapidly they restore the health of the environment and ecosystem.

They result in better crop yield since they don’t contain any toxic materials which may stop the crops from reaching their top state.

3, cost-effective

Compared to the chemical pesticides biopesticides are much cheaper this is due to the fact that biopesticides are produced naturally unlike the chemical ones which may require high amounts of resources and time to produce.

In addition to that you don’t need to apply significant amounts of biopesticide in order for it to work effectively as it with the chemical ones but small amounts can be enough.

4, less pest resistance

As time have passed new strains of pests were emerging and resistance against pesticides were developed in which left the agricultural society in a big dilemma.

Until the biopesticides came in 1990s since then resistance against pesticides were less often observed.

This another advantage of using biopesticides in which using biopesticides for longer period of time may result in totally elimination of a pest and its resistance developing ability over time.

5, safe to use

As the wise says “first safety” I my self deeply believe in this fact that says safety comes first and you need to apply all the necessary things to assure you have 100% safe conditions before approaching any method.

You need to make sure that the materials you are working with are not dangerous for your health

With biopesticides you don’t face such problems because biopesticides are 100% natural and the EPA had done a lot of researches before serving it to the market.

And unlike the chemical pesticides which has been rumored for years that they can develop disease such as asthma, reproductive dysfunction and Parkinson’s disease they are completely safe.



Chapter four: Disadvantages of biopesticides

Although biopesticides have many advantages they sill are not that perfect, some disadvantages accompany them and I tried to list some of them below.

1, high specificity

Don’t be confused to see high specificity to be mentioned here High it can also be a problem because an exact identification of the pest species is required in order for the the pesticide to work effectively.

The problem is that there are plenty of the species and it hard for hard you to know them all so research is required.

2, slow speed of action

Another disadvantage of biopesticides I want to mention is that Most of the time biopesticides are very slow in action and due to this fact they are unable to manage an immediate outbreak of pests.

3, short-term of use

Due to the fact that biopesticides decompose rapidly they are not capable of protecting the crop for longer period of time in which reapplying is required every season to make sure that all the crops are out of any threat.


Chapter five: conclusion

If you was unaware of biopesticides before reading this article I am glad to tell you that now you have enough knowledge of biopesticides to consider yourself as an expert.

As you saw in the article biopesticides are a more preferable pesticides when it comes to farming and I recommend you using them.

Although the chemical ones are polluting and expensive it won’t be that bad them sparingly while the biopesticides being our best choise.

And with this we end our article and I hope that you have learned a big lesson from this article and I hope at this very time you are totally out of confusion and next you will decide to choose the best pesticides in which I recommend biopesticides.
