Do nematodes really work?

Go out to the plants at night with a torch, shine it on the plants and believe me the little blighters just sit there and let you pick them off the plant. What you do with them is your business I just crush them, they are quite hard but it is very satisfying.

Depends what nematodes you buy and in what quantity.

I own an agricultural market research firm and we ask farmers this very question. It's actually a low percentage that find them of any benefit. Organic solutions like this can vary significantly. Better results were found in ladybirds for aphids.

That's all I can tell you without charging you for the study, I have to make a living!

if you are growing a bit of weed indoors yes, but if youve got a garden as much as i hate to say it you are gonna have to use chemicals,i try to use organic but vine weevils are a right pain and cause a lot of damage,my favourite organic is derris,comes in liquid or dust which i prefer,give your plants a liberal dusting,if no good its chemical warfare,good luck.
