When to use Capsanem?

Use Capsanem for the biological control of:

Lepidoptera – caterpillars
Tomato leaf miner larvae (Tuta absoluta)
Noctuids larvae armyworms (Spodoptera spp.), cotton bollworm, corn earworm (Helicoverpa sp.), tomato looper (Chrysodeixis chalcites), cutworms (Agrotis sp.), silver y moth (Autographa gamma), European pepper moth (Duponchelia fovealis)
Box tree moth larvae (Cydalima perspectalis)
Cranberry girdler larvae (Crambus hortuellus, Chrysoteuchia topiaria)

Colorado potato beetle larvae (Leptinotarsa decemlineata)
Flatheaded root borer larvae (Capnodis tenebrionis)

Shore flies larvae (Scatella sp.)
Tipulids-crane flies larvae / leatherjackets (Tipula sp.)

Other orders
Mirid bug (Nesidiocoris tenuis)
Sycamore lace bug (Corythucha ciliata)
Mole crickets (European mole cricket Gryllotalpa gryllotalpa, American mole crickets Neoscapteriscus sp.)

How does Capsanem 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 application, it simply falls to the ground.

Application Capsanem

Preparation of the spray solution
1. Remove the sachets from their packaging and keep them for 30 minutes at room temperature.
2. 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).
3. Stir well and leave the contents to soak for five minutes.
4. Mix again and pour the contents into the half-filled spray tank (except when tank mixing with a compatible product).
5. Maintain agitation of mixture in the tank (e.g. with a recirculation pump).
6. Make up the spray tank with the required amount of water.
7. If tank mixing with a compatible product, add Capsanem at the end to a fully filled tank.

1. 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.
2. To avoid blockage, all filters should be removed, especially if finer than 0.3 mm (50 mesh).
3. Use a maximum pressure of 20 bar / 290 psi (on nozzle).
4. The spray nozzle opening should be at least 0.5 mm (500 microns – 35 mesh) - preferably high flow rate cone nozzle types.
5. Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank.
6. Avoid sprayers equipped with centrifugal or piston pumps.
7. Water tank temperature must not exceed 25°C (77°F) and pH must be between 4 to 8.
8. Distribute the spraying solution evenly over the soil/media surface.
9. Application through irrigation systems and/or Dosatron Venturi 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 representative for specific advice.
10. Spray the solution as soon as it is prepared and within a short timeframe (5 hours). Do not store mixed suspensions.

Capsanem is compatible with many crop protection products. Check the Koppert side effects app for compatible products, or contact your local representative for advice. As a general rule for tank mixing, always add the nematodes to a fully filled tank containing the compatible product.
