| One of the key functions of caffeine in the plants that produce it is allelopathy – the ability to reduce competition from surrounding species by suppressing their growth. |
| It can provide a potent mixture of allelopathy and shade for the soil, inhibiting weed seed germination. |
| Secreted secondary compounds are positioned to be leached to the soil, in some cases for the purpose of contributing to allelopathy. |
| It's unlikely that allelopathy will totally replace herbicides in weed control. |
| Ideally, growers will vary cover crops from year to year to take advantage of different botanical characteristics such as rooting patterns, allelopathy and nitrogen fixation. |
| Potential biological control of weed in rice fields by allelopathy of dwarf lilyturf plants. |
