Sciarid Fly Nematodes Fungus Gnat Compost Fly Organic Natural Killer Treatment Treats 12.sqm

Product Information

Adult fungus gnats only live on liquids, and don’t actually do any damage to plants. Their presence is just very irritating. Young bedding plants, especially bizzie-lizzies, can be affected with large numbers of small flies covering young plants, whilst larvae eat the roots. Normally one application of Fungus Fly Killer is sufficient to kill most Fungus Fly larvae but large infestations may require further treatments. Predatory Mites

Media temperatures should be above 50° F but avoid applying when soil temperatures are above 80°F. Optimum media temperatures are between 60-70°F. Use a soil thermometer to monitor temperature. 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 Efficacy of biological control with beneficial nematodes will be variable depending upon the relative humidity and temperature in your greenhouse, dose applied, frequency of application, and life stage of thrips. As with any biological control measure, they are most effective when used preventively in conjunction with good cultural practices such as greenhouse sanitation and regular monitoring. For more information on Steinermena feltiae: Holding the spray bottle between 1 and 2 feet away, apply the pyrethrin mixture to the leaves and topsoil layer of fungus gnat-infested plants. Take care to spray both the tops and undersides of leaves, but don’t overly drench the plant or the soil surface. STEP 3: Reapply the mixture as needed.Effective: Kills at the early larvae stage preventing hatching; nematodes can hunt the larvae by themselves; nematodes multiply until all the larvae are dead Fungus gnats are often more numerous in composts that are constantly wet, allowing compost to dry can reduce infestations, provided this does not affect the health of plants. Potting media formulated for houseplants is the best choice for indoor plants The whole lifecycle is about 28 days, but the adult fungus gnats live only around 7 days. Where do fungus gnats come from?

Before adding the nematodes to the soil, make sure you soak the area because, like the fungus gnat, they prefer dark, moist environments. Once you’ve added the nematodes to the soil of your houseplants, they will get to work feeding on any gnat larvae that they find. Soil Drench to Kill Fungus Gnats This neem oil spray is also extremely effective against mosquitoes and will kill spiders, too. Nematodes for Fungus GnatsParasitoid wasps, Leptomastix species, Leptomastideaspeciesand Anagrusspecies. These are often available in combinations and with Cryptolaemusfor mealybug control.These parasiotoids are good at searching for mealybugs and can find them when populations are small. There are six different families of insects that make up the broader category of fungus gnats. These include the Sciaridae, Mycetophilidae, Ditomyiidae, Bolitophilidae, Diadocidiidae, and Keroplatidae. Most fungus gnat species are not harmful to our gardens, but the dangerous ones are in the Sciaridae family, especially those in the Orfelia and Bradysia species.

Calculating the number of nematodes you need depends on the treatment area. Generally speaking, we recommend 500,000 nematodes per square metre, which might sound like a massive population, but remember: they’re teeny tiny. Always use sterilized potting soil to pot plants. Additionally, keep extra soil inside of a closed container after opening its bag, and don’t mix compost into your potting soil unless it’s been completely finished and sterilized. Mix this powder in a 1.5L watering can and water the soil around your plant. Keep the soil moist for two weeks. The removal of peat composts to more organic based composts has been a positive move for the environment, but the new organic based composts do also attract more Fungus Fly, which enjoy feeding on organic matter. This has led to a general increase in the activity of this particular pests for many people growing house plants.The nematodes kill the fungus gnat larvae, which are hiding in the soil of your plants and hatching into more gnats. This prevents new flies from hatching and breaks the lifecycle. Water your plants less. Many a houseplant is watered more than it actually needs. Try watering it less and see how it responds. 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. Several species and combinations of species can be available including, Steinernema kraussei, S. feltiae, Heterorhabditis megidis and H. bacteriophora. Steinernema species can remain active at soil temperatures down to 5ºC (41ºF) whilst Heterorhabditis require temperatures above 12ºC (54ºF). Solarize potting soil and compost to sterilize it. To do so, place soil inside of a sealed plastic bag and pat it flat so that it is no more than 8 inches deep. Lay it on a raised location in the sun for at least a month—or two months or longer in cloudy places.
