I planted a new raspberry bed last year. They are doing very well.
I have experienced a very serious problem with a previous bed. They became infected with a maggot that eats the new growth while it is still dormant (late winter) and the new growth is then very weak and produces only a few shrivled fruit.
The adult insect looks like a yellow wasp (mud daubber) and hatches out about now, only to lay eggs in the late summer and reinfest the new crown that forms in the early fall.
I used to use Diazianon dissolved in water and drench the plants spring and fall to control this pest. Now Diazianon is no longer available.
Does anyone know what I can now use to control this pest in my new raspberry bed?

Have you tried Sevin Dust? Maybe some others here can help you better than me, I don't use chemicals- don't have a problem with those that do- so I'm not sure which are for what pests.
I hope you can get your problem solved- I love raspberries

if you can id the maggot, then I'd do a web search for that maggot and see what the treatments are. sometimes the treatment is chemical. sometimes it's bringing in another type of bug (which may or may not become another problem - lol )
i used to use alot of chemicals. now that I have kids, i try not to especially in areas they'll be. although I do still use chemical fertilizers as well as natural ones. where i live the fertilizer is critical. but i wash things before eating them too of course.
