Take 100gms to 150gms of garlic. Take 100gms curd. Mix both and grind in mixer. Add to two litres of water and keep this mixture covered in a corner undisturbed for seven to ten days. This will stink very badly, but it's an effective remedy. Strain this liquid and put in a sprayer bottle and spray thoroughly lifting the underside of the leaves too. Repeat once in ten days. This liquid has a shelf life of a month.
