| It seems to destroy the autotoxins and overcome the nervous inactivity. |
| Damaged plants, even if they survive, never produce as well as plants not affected by autotoxins. |
| These unwanted signs of lowered productivity were observed, let us say prior to 1950, but were not judged to be associated with autotoxins. |
| In continuously cropped fields, residues from decomposing watermelon plants are a primary source of autotoxins, which can inhibit watermelon growth and facilitate invasion of soil-borne pathogens. |
| The composition of the autotoxins produced and the primary microbial decomposers remain unknown. |
| Potential autotoxins have been explored for different compounds. |
