Re: help
Umer there are two things which makes the foliage rubbed. First is spider mites in this case the foliage looks like rubbed & some spider web is visible. Spider mites normally attack in long dry season.
Second is the Green Aphid (Sabaz thela) it attacks when the days are hot & nights are cool.There is no spider web since they are not from the spider family. Both pest are not easily visible. I am 100% sure this is Green Aphid. Spray Imeda Cloprid. Inshallah the problem will be solved.
The plus point is that keep the remaing Imeda Cloprid( under lock & key) which will help you in the early spring. Aphids normally attack roses & other plants in early spring & damage the buds. The buds either die or either fail to open due to Aphids. So the stored Imeda will help you again. Please try to purchase pesticide with max possible expiry date.

Re: help
You can also spray Acceta Meprid which will also help you against mealy bugs in the summer. So buy one pesticide & you will control two pests with one pesticide.

Re: help
Another thing you should do never sprinkle water on the foliage specially after the evening.Sprinkling water over the foliage will cause black spot which has no cure. Imeda Cloprid or Acceta will not kill spider mites. Oberon is the best pesticide for mites. But the case is not of mites my dear.
Re: help
Looks like mildew. A fungal disease precipitated by stress either through heat or moisture or nutrition deficiency. there are two types, Downy and Powdery.
Downy mildew develops spores only on the undersides of leaves, it appears in cool, wet conditions and is generally stopped by warm, dry, windy weather.
Powdery mildew will appear on both sides of leaves as well as shoots, buds and sometimes flowers. It thrives when foliage is dry and the weather is warm; wind spreads the spores to other plants. In fact, powdery mildew spores can’t germinate or grow when foliage is wet, so overhead watering is sometimes recommended as a preventative on highly susceptible plants.
Powdery mildew spores will overwinter on your roses, or in plant debris left from last year. When conditions are just right, this year’s growth can be affected and the disease spreads quickly. The optimum situation for the development of the disease is cool, humid nights followed by hot, dry days. If left unchecked, powdery mildew will cause leaves to turn yellow, die and fall off, leaving flowers unattractive.
What conditions are the roses growing in??? because if not right then that the real cause of the problem. You could as Farhan Sb said prune them and hope for the best the following year, however remember to burn the debris and goddi the planting bed free of weeds etc. If the overall conditions are not made right then they will fail to thrive and again succumb to the same mildews next year, eventually they will become so weak and spindly they die.
Give them better growing conditions without other plants competition until they are established and they will revive themselves. If they are under trees or next to vigorous plants as well as understory weeds/flowers rather than lose them I would be tempted to move them during the dormant season. A home made spray recipe of 10% milk solution works just as well as the leading synthetic fungicide and as well as sulphur. This will kill off most of the current fungus spores.
Good luck and my best regards
