Hydroponics farming has changed the pattern of growing herbs by providing a medium free system that is more productive, compact and profitable. This new method enables plants to be fed from a water solution which makes the growth rates faster and the yields higher than in the garden. When herb growers including the conventional gardeners and the commercial growers also shift to hydroponics, it is important that the growers should be aware of some features that are unique to the method.
As much as hydroponics is good for agriculture, it is not without some disadvantages. Hydroponic herb gardens have some challenges, the most common one being the outbreak of pests. Pests are known to affect plants in a very short time, stunt their growth and at worst decrease their yield, it is therefore important for the growers to be watchful and always on the look out for any signs of pest infection. In hydroponic system, plants are comparatively sensitive and require nutrient solutions for their growth, so identification of most potential pests and control techniques is crucial.
In this article I am going to discuss about the most prevalent pests of hydroponic herb gardens such as aphids, spider mites, and whiteflies with their indicators. Most importantly, this paper will give you working techniques on how to control these pests to enhance the health of the hydroponic garden. When equipped with the right information and equipment, your hydroponic herbs will grow well to give you fresh herbs for your dishes.
Common Pests in Hydroponic Herb Gardens
Aphids
Description: These tiny, fragile parasitic insects are available in green, black, and brownish colors. It is a sap feeder that is known to cause stunting, deformation, and in some cases death to a plant.
Signs of Infestation: Some of the things that you should look for include curled leaves, sticky substance (honeydew) and ants.
Spider Mites
Description: Spider mites are very small and almost impossible to see without a magnifying glass; they are pests that prefer warm and dry climate. They inject their bodies into plant cells and suck the contents, resulting in leaf damage and formation of webs.
Signs of Infestation: Rich yellowing of leaves, presence of fine webbing and speckled appearance of foliage are symptoms of spider mite infestation.
Whiteflies
Description: Small and white, these insects can fly and are similar in size to tiny moths which can lay eggs frequently. As with aphids, they feed on plant sap, causing stress and possible disease.
Signs of Infestation: The small white flying insects that are usually associated with this pest are easily seen, as well as the honeydew on the leaves.
Fungus Gnats
Description: Also known as sciarid flies, fungus gnats are gray, small and rather dark preferring moisture laden locations. Adults and their larvae are phytophagous and the latter feed on roots and organic substrata in the growing media.
Signs of Infestation: Some of the symptoms include: adult flies flying around plants and root damage in the seedlings.
Mealybugs
Description: These pests are covered with white, waxy substance that makes it look like small cotton like substance. They are plant sap suckers and they are known to cause growth retardation, and leaf shedding.
Signs of Infestation: One way to identify the problem is if white, cotton like masses can be seen on the stems and leaves of the plants.
Control of pests in hydroponic herb farming
Preventative Measures
Clean Environment: Maintain cleanliness in your hydroponic system to minimize pest invasions within your hydroponic garden. They should always check plants for any form of pest since this is a common sign that they are around.
Healthy Plants: Make sure that your herbs are healthy and fed. It was also established that strong plants are not easily affected by pests.
Biological Control
Beneficial Insects: Use predatory insects such as ladybugs or lacewings because these are natural enemies of most insects. This natural method can assist to keep the natural balance of living organisms in your garden.
Predatory Mites: Spider mites should be managed by introducing predatory mites that feed on the spider mites hence minimizing their number.
Cultural Practices
Proper Spacing: Do not cluster plants to allow for proper air circulation, which pests dislike and low humidity that pests love.
Rotation of Crops: Get rid of your herbs after some time in a way that will interfere with the pest breeding cycle in a way that will not allow pests to infest your plants.
Physical Controls
Insecticidal Soap: Insecticidal soaps should be used because they kill pests without affecting insects that are good for plants. It should be used topically as required over the affected part of the body.
Sticky Traps: Spray yellow sticky traps in your garden to control flying insects such as whiteflies and fungus gnats.
Monitoring and Intervention
Regular Inspections: It is recommended that you should take your time often to inspect your plants so that you can easily detect pest infestation. They should have signs of discoloration of the leaves, webbing or visible insects.Pesticides: However, if the infestations continue, the use of organic pesticides should be the last option. Make sure they are safe for hydroponics and read the application guidelines to the letter.
Conclusion
Hydroponics farming has the potential of enabling herbs growers to achieve high yields but the vice has its challenges especially in the area of pests. If you know the kinds of pest that could infest the hydroponic herb garden, you can avoid them or minimize their impact on your plants and get good yields. There are various ways in which one can practice hydroponics hence the need to practice monitoring, preventative measures and the use of both biological and physical methods in order to have a healthy and growing plants. With such measures, you will be on the right track of getting fresh home grown herbs throughout the year.
