Hydroponics is a type of plant growing that has no need for soil, and has several controlled systems that can help plants to grow faster and produce more produce. But as much as with conventional gardening, pests are inevitable in hydroponic systems and if not detected on time, will affect the plants. Hydroponic system is vulnerable to pests including aphids, spider mite, and fungus gnats which causes damage to the plant and low productivity. It’s important to know how to deal with these pests in order to protect your garden and its inhabitants.
Control of pests in hydroponics systems both requires preventive measures and active control measures. Some of the ways that can be used to manage pests include cleaning, checking for pests frequently and also introducing good insects. On the same note, the environmental factors such as humidity and temperature should also be regulated in order to reduce the growth of pests. In this guide, you will learn different techniques on how to minimize pest issues in hydroponics so that your plants are healthy and pest-free.
Below is a step by step guide on how to control and prevent pest in hydroponic gardening.
1. Keep Cleanliness and Hygiene
The most efficient method of minimizing pest problems in hydroponic systems is having a clean environment that is free from mold and bacteria. Some pests breed well in dirty conditions hence the need to clean all the surfaces, tools and containers used in your hydroponic system. Here’s what you can do:
Sterilize equipment: Also before using tools, containers or grow trays, wash them with warm water mixed with a bleach solution or any other disinfectants.
Eliminate plant debris: Both dead leaves and plant matter are known to attract pests to the garden and your home in general. It is also important to clear any debris from your growing area on a regular basis.
Clean water reservoirs: Water reservoirs where algae are found can attract pests. These should be cleaned often to avoid getting contaminated.
2. Monitor Plants Regularly
Pest detection is best done when you are inspecting your plants on a regular basis. The earlier one is able to identify the pests the better it will be to contain them. Inspect the following:
Leaves and stems: Look for signs of holes, discoloration or any other signs that suggest pest infestation.
Undersides of leaves: Some of the pests such as aphids and spider mite tend to hide under the leaves and therefore one has to take time to turn the leaves.
Water systems: Some pest like fungus gnats is associated with moisture so monitor the water and root of the plants.
3. Use Physical Barriers
It is critical to avoid pests from getting to your hydroponic system in the first place. Here are some ways to use physical barriers:
Install insect screens: Insect screens should be placed over the vents as well as the windows to help exclude pests from gaining access to the growing area.
Cover plants with row covers: Clear polyethylene row covers can protect plants from flying insects while at the same time letting in light and air.
Sticky traps: Spray your hydroponic system with sticky traps to capture flying insects such as whiteflies, thrips and fungus gnats before laying eggs.
4. Introduce Beneficial Insects
Another method of pest control is the use of beneficial insects that can be released into the hydroponic system you are growing. These insects feed on pests, and therefore useful in controlling the pests’ populations. Some examples include:
Ladybugs: Being aphid eaters, ladybugs would be a welcome addition to any hydroponic setup.
Predatory mites: These mites are predators that feed on other dangerous mites known as spider mites.
Parasitic wasps: Proven to be efficient in suppressing and eradicating the whitefly.
5. Velocity of air flow, humidity and temperature
Some pests are known to favor certain environmental conditions and therefore, controlling the conditions in your hydroponic system will also help to control pests. Most of the pests thrive well in places with high humidity and warm temperatures. You can manage these factors by:
Ventilation: Proper ventilation should be provided so that the humidity levels in the growing area should be controlled.
Dehumidifiers: They should use a dehumidifier to regulate the amount of humidity in the air in their homes.
Temperature control: Maintain the temperatures to a reasonable level, and avoid high temperatures that would enhance reproduction of pests.
6. Use Organic Pesticides
If pest pressure is high, organic pesticides can be used safely in hydroponic system as a means of pest control. These are less toxic to plants and pollinators, and effective against most pests that affect plants. Consider using:
Neem oil: Neem oil is effective for most of the pests like aphids, whiteflies and mites.
Insecticidal soap: This is a contact spray that will effectively kill soft-bodied pests such as aphids, and thrips without affecting the plants.
Diatomaceous earth: A natural powder that acts as an abrasive and kills pests on contact as it destroys their hard outer cover.
7. Biological Control Agents
In a more detailed procedure of pest control in hydroponics, the biological control agents which include bacteria and fungi can be used. These agents target specific pests without affecting your plants:
Bacillus thuringiensis (Bt): It is a naturally occurring bacterium which has been found to control caterpillars and some other larvae.
Beauveria bassiana: A mutualistic fungus that parasitizes and kills several insect pests including aphids, whiteflies, and thrips.
Conclusion
Pests in hydroponic systems are best controlled using a lot of attention, frequent checkups, and by employing various methods. It is therefore important to practice hygiene, introduce useful insects in the garden, control the environment and use organic chemicals to manage the pests affecting the hydroponic garden. Just like with any pest issue, it is always important that you act as soon as you can before the problem gets out of hand, so make sure to check on your plants often to minimize your risks of getting an infestation. When these strategies are implemented, you can be assured of a healthy pest free hydroponic garden.
