Optimal rates of beneficial nematodes required to treat different sizes of area
How many nematodes should be applied?
For the successful control most of the soil dwelling insect pests, the optimal rate of 1 billion infective juvenile nematodes in 100 to 260 gallons of water per acre is generally recommended.Table1. Showing the number of nematodes required to treat different sizes [area in sq ft (sq M)] of lawns or fields
