50000000 larvanem for a knapsack sprayer for 1000m square
Instructions for the Koppert Larvanem (Heterorhabditis bacteriophora) are as follows
Preparation of spray solution
Put the contents of the pack into a bucket containing 5 litres of water 59-68F (15-20C).
Stir well and leave to soak for 20-30 seconds.
Stir well once again and pour the entire solution into the spray tank.
Top up until the required amount of solution is in the tank.
Spray immediately after preparation.
Use the whole pack in one go, as the distribution of nematodes in the pack is not homogenous.
Application and dose
With a watering- can, sprinkler system, backpack spray unit or vehicle-mounted spray unit.
To avoid blockage, all filters should be removed.
Use a maximum pressure of 12 bar on spraying boom or pistol.
The spray nozzle opening should be at least 0.5 mm (500 microns).
Spray over the soil surface.
Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank.
Water the crop before and after application.
Keep the soil moist for the first 2 weeks after application.
