A 0.5 per cent solution of baking soda and water (3 teaspoons baking soda per gallon of water) sprayed on roses is a remedy for black spot and powdery mildew. (Based on research by R.K. Horst, professor of plant pathology at Cornell University).
Try insecticidal glue spray! Mix 4 fluid ounces (one half an average-sized bottle of glue) white glue in 1 gallon warm water. Spray the glue mixture on the twigs and leaves of infested fruit trees; soft-bodied bugs, like aphids, red spider mites, scale, and mealybugs, will all be killed. When the glue is dry, it will flake off with the dead insects. Repeat treatment in seven to ten days as necessary.
Don’t hog water! Clean your sidewalks with a broom, not with a hose!

Remember that three thousand litres of water go into producing a kilo of sugar! 5,000 litres are needed to get an equivalent weight of rice or cheese to go to the table and a scary 20,000 litres go ino the same amount of coffee! From: Seven Years to Save the Planet by Bill McGuire.
What we can do is save water by rainwater harvesting, using water from washing vegetables and fruits, in the garden to water plants, and stop leakages at once. In India, in Government buildings, especially inside toilets water leaks horribly, frighteningly, from sinks and small taps, and no one cares a bit!
