Natural Kleaner: A Natural Alternative for Controlling Plant Pests

Protecting Crops from Pests: The Limitations of Conventional Treatments

Growing plants—whether outdoors, in pots, in the ground, or indoors under artificial lighting—requires constant attention. Among the many factors to manage, pest control is one of the key challenges in maintaining crop health.

In their natural environment, plants have mechanisms that allow them to adapt to external conditions, grow, and cope with various types of stress. However, the growing conditions we impose on them are often far removed from this natural balance.

Monocultures, simplified ecosystems, unsuitable growing media, and soils depleted of microbial life can weaken plants and make them more vulnerable to external stressors.

Among the most difficult threats to control are insect and mite pests. Their presence can quickly jeopardize plant growth and lead to significant losses. Farmers and pests have always been locked in a constant battle, for which no universal solution has yet emerged.

While conventional chemical treatments can certainly help control certain infestations, their use raises environmental concerns and can have consequences for non-target organisms. Natural alternatives, such as neem oil or plant extracts, are also available. However, they sometimes have limitations on their use, particularly as harvest time approaches.

In fact, many treatments cannot be applied during the final days of ripening. Pests can therefore continue to multiply during this particularly critical period.

We developed Natural Kleaner to address this issue: a naturally derived solution designed to act directly on pests found on foliage. Its mode of action relies primarily on a physical process that coats insects and larvae, without resorting to chemical insecticides. Its biodegradable formula can also help nourish the plant as it breaks down.

Another notable feature is worth highlighting: Natural Kleaner can be used up until the day before harvest for most plants, in accordance with the product’s usage recommendations.

Natural Kleaner: A New Way to Care for Your Plants

To protect plants while minimizing the use of conventional treatments, we have developed Natural Kleaner, a foliar cleaner that uses a mechanical approach to control pests.

What is Natural Kleaner, the natural leaf cleaner?

Natural Kleaner is a naturally derived, vegan, and biodegradable foliar cleaner. What sets it apart is its physical mode of action: it forms a coating around insects and larvae on the surface of leaves.

In addition to helping remove impurities from the foliage, it helps control various pests that may infest the above-ground parts of plants, particularly spider mites.

Its formula is designed to clean leaves without using harsh chemicals. It therefore serves as a complementary solution for maintaining foliage and limiting the presence of unwanted organisms.

Natural Kleaner offers several features that are of interest to growers:

  • Natural origin: a formula derived from natural sources, vegan, and biodegradable.
  • Mechanical action: Coating insects and larvae allows for physical control of pests.
  • Foliar cleaning: Helps remove impurities from the leaves.
  • Wide range of uses: Suitable for controlling various foliage pests.
  • Pre-harvest interval: Can be used up to one day before harvest for most plants.


It can therefore be easily incorporated into routine crop maintenance practices and has been tested by professionals.

They’ve tested it and approved it

Natural Kleaner has already won over many users and vegetable growers, who have incorporated it into their farming practices.
Their feedback provides concrete examples of how this foliar cleaner is used on different crops and in various situations.

How to Use Natural Kleaner? Dosage and Application Tips

To get the most out of Natural Kleaner, it is important to follow the dilution ratios and proper spraying techniques.

Preparation and application:

  1. Shake the bottle well before each use to ensure the solution is thoroughly mixed.
  2. Dilute 25 ml of Natural Kleaner per liter of clean water.
  3. Spray the solution evenly onto the leaves, making sure to cover the foliage thoroughly.

When should Natural Kleaner be applied, depending on growing conditions?

Natural Kleaner can be used at various stages of the growing cycle: when setting up the plants, at planting time, or during their growth.

It can also be applied up to one day before harvest. No rinsing is necessary before harvest, provided the product is used as directed.

However, the timing of spraying must be adapted to the growing environment.

When growing under artificial lighting:

It is recommended that you spray a few minutes before the lights are turned off. This prevents application during the lighting period.

When growing under natural light:

Apply the product in the early morning or late afternoon. It is important not to apply the product when the plants are exposed to direct sunlight.

Nettoyage intensif ou entretien préventif : quelle fréquence choisir ?

The frequency of application depends on the desired result and the condition of the foliage.

For a deep clean:

In cases of heavy pest infestation or when the foliage requires thorough cleaning, applications may be repeated every two days until the desired result is achieved.

For routine cleaning:

As part of a regular foliage care routine, an application every one to two weeks may be considered.

What sizes of Natural Kleaner are available?

To meet the various needs of growers, Natural Kleaner is available in several package sizes:

  • 0.25 L
  • 0.5 L
  • 1 L
  • 5 L

These different sizes allow you to choose the right amount based on the size of the cultivated area and the frequency of use.

Natural Kleaner: Compatibility with Fertilizers, Growing Media, and Biological Pest Control

Can Natural Kleaner be used in combination with other gardening products?

Natural Kleaner was designed to integrate easily into various growing systems.
It is compatible with different types of fertilizers and biostimulants, as well as with mineral and organic growing media.
It is suitable for use in both hydroponic systems and outdoor cultivation.

Combination with biological control agents:

Natural Kleaner can also be incorporated into an integrated biological control strategy, complementing the use of natural predators and other beneficial organisms.

However, one precaution is essential: you must wait 24 hours after application before introducing biological control agents. This waiting period helps minimize the risk of interaction between the treatment and the beneficial organisms.

Precautions for Use and Storage of Natural Kleaner

To ensure proper use and preserve the product’s properties, there are a few recommendations that should be followed.

Precautions to Take During Application

  • Avoid spraying in direct sunlight or when temperatures are particularly high.
  • For sensitive plant species, conduct a preliminary test on a small portion of the foliage before treating the entire crop.
  • Follow the recommended dosage of 25 ml per liter of water.
  • Adjust the timing of application based on light conditions and the growing environment.

How should Natural Kleaner be stored?

To keep the product in good condition after opening, be sure to follow these instructions:
