I did forget to mention that the H.
bacteriophora beneficial nematodes are very good against Japanese Beetle
grubs. The best way to fight them is to get the grubs before they morph
into beetles while they are still in the ground. The H. bacteriophora
also are good against asparagus beetle, bagworm, banana weevil,
banana moth, bill bug, black vine weevil, cabbage root maggots, carrot weevil,
citrus weevil, Colorado potato beetle, cucumber beetle, European chafer, adult
flea, flea beetle, gall midge, Japanese beetle, masked chaffer, May/June
beetles, strawberry root weevil, sugarcane stalk borer, sweet potato weevil,
various tree and vine borers. At $85 per acre, it is rather expensive
for commercial use since our typical spray runs about $50/acre, but
for small scale use, it is a great alternative to more toxic
chemicals.
