Hi, my chilli plants have become covered in greenfly and although I've sprayed the numerous times it dosent seem to be having any affect? The buds are now drying up and falling off which I assume is down to the greenfly! Any suggestions on what I can do?

Pic above of stuff I used! Plants leaves all still look fine do you think more buds should appear or am I best taking them out and starting again?

One, or at the most two applications should have been enough to kill the greenfly. Although they were probably still on the leaves I'm sure that they would have been the dead ones.
As you mentioned that you sprayed them numerous times the problem could be that you used too much insecticide. Also, using Provado in extreme weather conditions, i.e. bright sunlight could cause the buds to drop.

Thanks for your reply and I guess a lesson learned! But they still have lots of greenfly but I think I probably have caused the problem through over doing it!

try a spray with a little washing up liquid in it and make sure you do under the leaves as well. as a few missed can breed faster than rabbits, flowers should regrow unless you have overdone it spray above is much gentler than your spray .

Thx for replys! When you say a spray with a little washing up liquid is this just soapy water or add this to the bug spray?

Soapy water.

Dodger, if you mix a solution of washing-up liquid and water, roughly twice as strong as you would normally use for the dishes and spray it on the leaves as Eamonn said then this should do the trick. I also add about 2 tablespoons of cooking oil per 3 litres of this mix. The oil will mix with the solution because soap is an emulsifier. When the the water evaporates the oil will cling to the leaves and forther discourage the aphids. It doesn't need to be washing-up liquid, any soap will do.
The advantage of using soap, especially on plants that you're going to eat is that it's organic, hence no nasty chemicals and it's to hand. I have always found that this works for me so I stick with this method instead of buying expensive chemical pesticides.

It could be the greenfly has caused the damage, it could also be that you have used too much insecticide and that has seen your chillies off. What kind of spray did you use?
