Steinernema Feltiae x50,000,000 (ENTON)

Steinernema feltiae is an effective natural solution for controlling fungus gnat larvae, Vine weevil larvae, thrips pupae, and other soil-dwelling pests. These beneficial nematodes actively seek out and eliminate pests below the surface with no residue or harm to plants, pets, or people. Easy to apply and highly effective, S. feltiae is the go to biological control for healthier roots and thriving plants in greenhouses, gardens, and indoor growing environments.

Active Ingredient

1 x pack of 50 million- Steinernema feltiae

Technical Comments

Environmental conditions: Steinernema feltiae is active between 10-31°C/50-88°F but performs best at temperatures between 14-26°C/57-79°F. Soil or air temperature below 5°C/41°F and above 35°C/95°F can be lethal Nematodes are susceptible to ultraviolet light (UV): do not use them in direct sunlight

Timing: Timing and frequency depend on the pest species and the crop environment (relative humidity, soil moisture and temperature). Consult an Indoor Organics technical advisor for advice on the best strategy for your situation.

The moisture content of the soil must be kept high for several days after application. When possible, irrigate the crop before and right after application. For foliar application, spray Steinernema feltiae when relative humidity will exceed 75% for several hours after the treatment.

Activity / Control

Steinernema feltiae can be used for biological control of various insect pests indoors. It is effective at low temperatures, thus can also be applied in colder parts of the season. Pests controlled: Fly larvae (Diptera): Sciarid flies (Lycoriella spp., Bradysia spp.); Shore flies (Scatella spp.); Leaf miners (Liriomyza spp.), Leatherjackets, Thrips (Thysanoptera) pupae and larvae: a.o. Western flower thrips (Frankliniella occidentalis), Weevil larvae (Coleoptera): Black vine weevil (Otiorhynchus sulcatus); Other weevils (Otiorhynchus spp.), Caterpillars (Lepidoptera): Tomato leaf miner moth (Tuta absoluta); Oak processionary moth (Thaumetopoea processionea); Common swift moth (Korscheltellus lupulina); Noctuidae: Armyworms (Spodoptera spp.); Cotton bollworm (Spodoptera littoralis); Corn earworm (Helicoverpa zea); Tomato looper (Chrysodeixis chalcites); cutworms (Agrotis spp.); Silver-Y moth (Autographa gamma), Bugs (Hemiptera): Sycamore lace bug (Corythucha ciliata)

Application Method

Preparation: Remove the sachets from the box and keep them at room temperature for 30 minutes. Empty the contents of the sachets into a bucket containing at least 2 litres of water per sachet (water temperature: 15-20°C/59-68°F). Stir well and leave the contents to soak for five minutes. Stir again apply directly after preparation of solution.

Application: Nematodes can be applied using a watering can, a pump sprayer, through a sprinkler system. To avoid blockage, all filters should be removed, especially if finer than 0.3 mm (50 mesh) Use a maximum pressure of 20 bar/290 psi (on nozzle). The spray nozzle opening should be at least 0.5 mm (500 microns – 35 mesh) – preferably high flow rate cone nozzle types Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank. Avoid sprayers equipped with centrifugal or piston pumps. Water tank temperature must not exceed 25°C/77°F and pH must be between 4 and 8. Distribute the nematode/water solution evenly over the soil/medium surface.

Application through irrigation systems: Pressure-compensated irrigation systems are recommended. If not available, spray or drench applications are recommended. For injection through Dosatron/Venturi systems, please contact Indoor Organics for specific advice. Spray the solution as soon as it is prepared and within a short timeframe. Do not store mixed suspensions.

Application Rate

Steinernema feltiae is typically applied at a rate of 250,000 to 500,000 nematodes per m² for soil application and 1 to 3 million nematodes per litre for foliar applications
