For many, farming is more than just a livelihood. It’s an adventure.

If you are someone who loves plants or has been doing farming or agriculture for a while, you probably already know the importance of protecting our crops from invaders.

As you know, we utilize the services of different pesticides in order to deter, incapacitate, control, or discourage pests.

Let me tell you, the overall sustainability of crops depends largely upon the use of pesticides.

By controlling invasive species, you’ll be able to improve the yield and quality of the crops you grow. These are classified depending on their uses and the type of pests they control.

One of these types is known as systemic insecticide, which is primarily responsible for the control and treatment of insects.

For this reason, you need to equip yourself with the relevant information when using systemic insecticide.

I have prepared this guide to assist you in with all the relevant information you may need, have a look.

 

What is Systemic Insecticide?

Systemic Insecticide

Systemic Insecticides are chemicals which are absorbed by plants and renders its parts poisonous to certain pests and invading organisms.

After being absorbed through the microscopic cells on the surface of the leaves, stems, and roots, it moves through the plant by using water conducting ( xylem) and food-conducting tissues ( phloem) as pathways.

In case you are wondering when it was first developed to become the most widely used insecticide in the world today, it all started during the 1950s when soluble organophosphorus compounds were first introduced.

These were primarily responsible for controlling burrowing larvae and sucking pests in crops. Nowadays, soluble organophosphorus compounds are the most popular pesticide used in developing tropical countries.

In 1991, Neonicotinoids and Fipronil, which are the most common systemic insecticides were developed and was introduced to the market for commercial use in the mid-1990s.

Having an estimated 40% share in the world market, these group of systematic insecticides has become the most widely used globally.

Systemic Insecticides  can be applied in conventional ways—as sprays, dusts, or granules.

 

Systemic Insecticide List

Currently, you can find various types of systemic insecticides available in the market. These are classified based on their specific uses.

In order to guide you better in choosing what’s best to use for your agricultural needs, below is a complete list of systemic insecticides:

       Carbamates.

Carbamate Insecticides has the same level of toxicity as Organophosphates. However, it has less severe and more reversible effects. It is an acetylcholinesterase enzyme (AChE) inhibitor that   blocks nervous impulse transmission through neuronal synapses.

  • Aldicarb
  • Bendiocarb
  • Butocarboxim
  • Butoxycarboxim
  • Carbofuran
  • Ethiofencarb
  • Methomyl
  • Oxamyl
  • Pirimicarb
  • Thiodicarb
  • Thiofanox
  • Triazamate

        Dithiol.

A type of organosulfur, or organic compounds which contain sulfur. These are compound which normally contains two thiol groups.

  • Cartap

        Insect Growth Regulator.

These are chemicals that inhibit the growth of insects by mimicking their hormones and disrupting how insects grow and reproduce.

  • Halofenozide
  • Hexaflumuron
  • Novaluron
  • Teflubenzuron

 

Neonicotinoid.

These are chemicals which are especially effective when used against sap-feeding insects. It is classified as a neuroactive insecticide and is and has chemical similarities with nicotine.

  • Acetamiprid
  • Clothianidin
  • Dinotefuran
  • Imidacloprid
  • Nitenpyram
  • Thiacloprid
  • Thiamethoxam

Organophosphate.

This belongs to a group of insecticides which act on the enzyme acetylcholinesterase enzyme (AChE).

  • Demeton S – Methyl
  • DIcrotophos
  • Dimethoate
  • Disulfoton
  • Fenamiphos
  • Fosthiazate
  • Heptenophos
  • Methamidophos
  • Mevinphos
  • Monocrotophos
  • Omethoate
  • Oxydemeton – Methyl
  • Phorate
  • Phosphamidon
  • Thiometon
  • Vamidothion

Phenylpyrazole.

these are broad-spectrum insecticides designed to address problematic insect resistance.

  • Fipronil

 

How To Apply Systemic Insecticide ?

The following are the common methods of applying synthetic insecticides:

Foliar Spraying –

Although it cannot substitute for healthy soil, foliar spraying is usually recommended for some plants which suffer from nutritional deficiencies.

It is an effective option when taking on and taking out various kinds of harmful insects.

Foliar application means applying the insecticide directly on the foliage. Through the pores on their surface, leaves are able to absorb the chemicals.

This absorption occurs in the stomata and epidermis. Although it may travel faster through the stomata, efficiency in absorption is the same through the epidermis.

Doing foliar pesticide spraying, it is always advised to use a small amount as possible and necessary. It Is only considered a supplement to regular soil application.

Remember to be cautious when doing foliar application during summer.

Normally, labels will give instructions as to what degree of temperature you should avoid in order for the leaves not to get scorched. This can still happen cooler temperature, but the incidence is definitely higher during the warm season.

 

Drenching the Soil –

This involves the process of applying the diluted products directly to the base of the plant in order to provide deep and targeted penetration.

It is an effective way to treat trees with severe pest infestation.

This process helps identify the particular plant for the chemicals and reduce the likelihood of the chemicals affecting the other plants.

Soil drenches generally takes effect slowly, especially if you’re trying to treat a large plant or a tree.

It takes time for the chemicals to spread from the base of the tree where it was applied to the branches, stems, and leaves. Because of this, it is advised that soil drenching is done during spring.

This gives enough time for the chemical to work through the plant before bugs start coming out in force.

Most drench chemical products include labels and specifics as to the amount of chemical you need to apply. This generally depends on the size of the plant.

 

Treating the Seeds-

Seed treatment is one of the cheapest and safest methods of chemical application to treat infestations.

The benefits of using this procedure include lower risks to workers, minimized possibility of runoff to waterways, and a lower overall amount of pesticide in the environment.

There are different techniques of seed treatment which aims to improve the growth environment of the seed, seedlings, and plants.

  • Seed Dressing. The most common technique of seed treatment wherein the seeds are dressed using a dry formula or wet treated with a liquid chemical or formulation.
  • Seed Coating.This technique requires an advanced technology wherein a binder is used with the chemical to increase adherence or attachment to the seed.
  • Seed Pelleting.  The most advanced seed treatment technique, it requires a special machinery which results in changing the physical shape of the seed to improve palatability and ease of handling.

 

CONCLUSION

 

Systemic Insecticides, when used properly, offer numerous advantages such as providing a higher yield and better quality of crops.

It also enables you to lower down the total cost of labor by ensuring a long-term protection from insect pests, thus decreasing the need to rely on routine insect spray applications.

With these in mind, it is no surprise why systemic insecticides are the most widely used pesticide in the world today.
