Calcined soda, or sodium carbonate, Na₂CO₃.

Uses. Sodium carbonate has proved to be an effective product for combating various pests:

Against powdery mildew: dissolve 2 tablespoons of soda in a 10 L bucket of water, mix thoroughly and add 40 g of crushed household soap. Spray every 7 days.
Against grey mould: dissolve 1 tablespoon of soda in 10 L of water and spray affected plants. Repeat several times, but no more often than once every 2 weeks.
To protect viburnum against viburnum leaf beetle (Pyrrhalta viburni): mix 1 bar of green soap with 10 L of water and 1 tablespoon of soda. Treat the undersides of the leaves weekly until the pest has completely disappeared.
Against aphids and other vegetable-crop pests: mix soda with ash, pollen or vegetable flour at a ratio of 1:1 and spread it thickly over the plants. Do not do this in hot weather, as it may damage leaves.
