Kindly suggest the possible remedy for disease because of this the plant doesn't grow and it's leave are like this

Hi! This is effected by Mealybug Pls Clik on blue link for more inf.. (For home remedy) Dry dish soap and laundry detergent contain chemicals that are harmful to plants, so avoid using these when making a soap spray. To make a soap spray for controlling mealybugs on plants, mix 2 teaspoons of mild liquid dish detergent in 1 quart of water & spray.

Its due to Mealybug infestation. Visit plantix library for more info.
