Worse from damp (337)
Insects, plants in general. Important 'pesticide' for cabbage, eggplant, squashes, cucumber, potato, wine vines, and fruit trees. (1810)
In warm and humid spring weather a lilac showed wilting and blackening blossoms. Sprayed foliage and blossoms (sparingly) with Cuprum 30c in water, one time. Due to lack of time, the diseased tissues were not removed. In the following weeks the blossoms dried up. No further evidence of disease. One month later the considerable amount of new growth looks perfectly healthy. (1534)
