Our invaluable Potato, which enters so largely into the dietary of all classes, belongs to the Nightshade tribe of  dangerous plants, though termed "solanaceous" as a natural order because of the sedative properties which its several genera exercise to lull pain.
In the courts were small plantations of tobacco, and a little solanaceous plant which the Balonda use as a relish; also sugar-cane and bananas.
The milk of goats does not coagulate with facility, like that of cows, on account of its richness; but the natives have discovered that the infusion of the fruit of a solanaceous plant, Toluane, quickly produces the effect.
(Corn earwomm) garlic and onion, peanuts, solanaceous crops

There are solanaceous weeds that carry diseases harmful to solanaceous garden plants.
Rotating crops from other families, such as chilis from the solanaceous family, will control the pathogen.
Some diseases only affect certain crop families, for example tobacco mosaic virus (TMV) only occurs in solanaceous crops (tomato, pepper, eggplant, potato, tomatillo), and the fungus causing clubroot only on crucifers
In the case of TMV, nonsolanaceous crops can replace those that have succumbed to virus, although solanaceous crops may be tried again the following season because the virus does not remain in the soil.
