When to use Entonem?

Entonem can be used for biological control of various insect pests in protected crops and urban green. It is effective at low temperatures, thus can also be applied in colder parts of the season.

Pests

• Fly larvae (Diptera): Sciarid flies (Lycoriella spp., Bradysia spp.); Shore flies (Scatella spp.); Leaf miners (Liriomyza spp.)

• 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)

How does Entonem work?

The nematodes enter the pest and release symbiotic bacteria into the body cavity. These bacteria convert the larval tissue into a food source, on which nematodes feed, develop, and reproduce. The host pest dies within a few hours to days after infection. The Infected host turns yellow to brown but may be difficult to find, due to rapid degradation in the growing media, or, as with foliar pest, it simply falls to the ground.

How to use Entonem?

Preparation of the spray solution

• Remove the sachets from their packaging and keep them for 30 minutes at room temperature

• 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 and pour the contents into the half-filled spray tank (except when tank mixing with a compatible product)

• Maintain agitation of mixture in the tank (e.g. with a recirculation pump)

• Fill the spray tank with the required amount of water

• If tank mixing with a compatible product, add Entonem at the end to a fully filled tank

• Apply directly after preparation of spray solution

Application

• Nematodes can be applied using a watering can, an airblast sprayer, through a sprinkler system, with a backpack sprayer, or a vehicle-mounted spray unit

• 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 spraying 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 your local Koppert representative for specific advice

• Spray the solution as soon as it is prepared and within a short timeframe. Do not store mixed suspensions

Best working conditions for Entonem

• 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

• 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 Entonem when relative humidity will exceed 75% for several hours after the treatment

• Adding an adjuvant and/or an anti-desiccant/humectant can be beneficial. Ask your Koppert representative/distributor for more information

• Spray in the evening (or morning in some cases) allowing nematodes to work for several hours within the optimal range of temperature and humidity, as described above

Product Handling

• Storage time after receipt: See expiry date on the box. On average product can be stored for 2-3 months

• Storage temperature: Refrigerate at a temperature of 2-6°C/35-43°F in a ventilated refrigerator/cold room

• Storage conditions: Upon receipt, take boxes out of the insulating shipment packaging. Keep in a dark, ventilated refrigerator/cold room until use
