I really don’t know what kind of pesticide to use. I would appreciate help. The growth of the rose plants has been retarded. When ever the new shoots seem to be growing it turns black and dies . I am located in India and all my roses are in pots. I would appreciate if I could get to know about the specific pesticide. All the answers were excellent to my previous query. I really need help desperately.
I am located in Kolkata India and the weather is humid and the temp is high for November

I answered your question that you had posted yesterday and had no idea you were located in India.
Your problem is due to a "Rose Midge" infestation. There are several options for you......and probably the best way is to use one of the following sytemic insecticides; Orthene or Cygon. Be sure to get good coverage of flower buds. Remember to read the labels and follow directions regarding rates and frequency of application.
Diazinon, a non-systemic, is also an option, but larvae can be protected from the chemical within the flower or vegetative buds.
I'd also recommend you do an online search for "Rose Midge" to determine if that's the problem you're having on your roses.... but according to your description.... it certainly sounds like that's your problem.
Hope you found this information helpful. GOOD LUCK!

If the pots are not drained properly, you are flooding the root system. If draining doesn't help then your roses have a virus blight and should be destroyed to prevent further contamination. Pesticides will not help. Get rid of the soil the plant is in, also. Start over with new potting soil and new plants.

Sounds more like a fungus to me. You need to find a good fungicide. I am in the US so I can't tell you one to buy because I don't have a clue what is available to you. Find out what time of year is right to cut your bushes back and do so. Hope you find what you are looking for.
