The Fungus Fly Killer nematode pack (50 million) is designed to treat an area of up to 100 square metres or approximately 2000 2-litre pots. Before application, make sure the compost is damp or moist. To prepare, mix the contents of the pack with 5 litres of water and stir thoroughly. Next, take 0.5 litres of this solution and add it to an 8-litre (2-gallon) watering can filled with clean water. Stir well and water the compost using a coarse rose attachment. This concentrate can be used to fill up to 10 watering cans. Alternatively, a knapsack sprayer can also be used for application.
