Sciarid Fly Killer Nematodes 15 sqm

Product Information

Some species of nematodes are plant-eating, but the ones in your biological control product are insect-eating. As such they will have no effect on your plant, as they cannot consume any part of the plant. Yes, disposing of the top 2-inch layer of potting soil is an important aspect of getting rid of fungus gnats. Replace that soil with new, sterile potting mix suited to the particular plant, and consider topping it with a half-inch of sand or diatomaceous earth to make the plant less hospitable to the bugs.. Final Thoughts

Marigolds make great bedding partners for carrots, celery, and onions to help keep invading species at bay. Alternatively, plant marigolds in your fallow soil — that will also keep the nematodes away. Any questions Mix powder in 1.5 L of water and apply evenly to the area to be treated using a watering can or hose end sprayer. Water from the bottom using a tray, rather than the top. Since the eggs tend to be laid near the top of the soil, this prevents the top section becoming too moist. Mix this powder in a 1.5L watering can and water the area, preferably the ants nest. Keep the soil moist for two weeks. Repeated applications are often needed. Reapply in 2 to 4 weeks under moderate to heavy infestations. For longer term crops, apply at the beginning and at mid-crop.

Fungus gnats reproduce and develop optimally within overly moist or saturated media; therefore, moisture management is critical for preventing major fungus gnat outbreaks. 5 Fungus gnat survival is the highest when media is kept at a constant moisture level of 50%. 5 Growers should practice proper moisture management by allowing the crop to dry out between irrigations. Proper irrigation management also aids in reducing excess moisture on production floors and media surfaces, thus, reducing algal growth that benefits fungus gnat populations. Additionally, installation of cement floors or geotextile fabrics under growing benches and frequent removal of spent media under the benches can help reduce algal growth and discourage fungus gnat activity. 1 Physical Control Certain predatory mites can also be applied to the surface of the house plant compost, and can provide a very useful additional control of Fungus Fly. These tiny predatory mites feed on the small Fungus fly larvae they locate on top of, and just under, the compost surface. The most effective predatory mite to apply against Fungus Fly is called the Macrocheles robustulus, also known as Mighty Mite. And that’s it. You should see results in around 3-7 days, although you may have to wait between two and four weeks for the full effect. Fungus gnat larvae damage plants by feeding on plant roots. They are especially destructive to seedlings and young plants, but can also damage mature plants if numbers are high. Larvae can tunnel into succulent stems at and below the growing medium surface. This tunneling collapses the stem causing the plant to wilt, or grow less vigorously. Larvae are capable of transmitting fungal pathogens such as Pythium, Thielaviopsis, and Fusarium. In addition, larval feeding creates wounds that allow secondary soil-borne pathogens to enter roots. Adult fungus gnats are also capable of transmitting fungal pathogens, including Botrytis. In addition to damaging plants, fungus gnat adults emerging from plants in wholesale or retail situations are considered a nuisance that can affect plant sales. Shore Flies

Nematodes (phylumNematoda) are a very diverse group of animals. There are more than 25,000 described species, and they are found in almost every habitat. Most are microscopic and theyare important components of soil and marine ecosystems. Many nematodes are free living, but more than half of described species are parasitic on plants or animals. A fewspecies such as the potato cyst nematodes ( Globoderaspecies), leaf and bud nematodes ( Aphelenchoidesspecies)and stem and bulb nematodes ( Ditylenchus dispasci) can feed on garden plants.The harmful species invade the root system and change the plant’s metabolism via their saliva. For example, Beet cyst nematodes (Heterodera schachtii) can damage beetroot, spinach, and rapeseed. Note: It is important to read manufacturer's instructions for use and the associated safety data information before applying chemical treatments. Organic Fungus gnats are tiny flying bugs belonging to a few insect families (namely Sciaridae, aka dark-winged fungus gnats). They eat plant matter, mulch, compost, and—true to their name—fungus. All of these materials can be found outdoors, but these dietary needs can be found even more reliably in potting soil for houseplants. Their attraction to potting mix’s warmth and moisture makes fungus gnats particularly problematic indoor pests.

Fully-grown plants are much less likely to be damaged, but can be if there's no other food source for the Scaridae. Where do gnats live? Figure 1. Fungus gnat larvae.

Fungus gnat numbers grow exponentially, and once set in can be hard to eradicate completely. Traps

Once a gnat infestation is controlled, there’s still a good chance they’ll return if you don’t take proper fungus gnat prevention measures. Carefully discarding the topmost layer of potting soil outdoors and replacing it with sterile mix is only part of how to prevent fungus gnats in houseplants. The above gnat treatment methods will be most effective if you also take the following steps:
