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.
