Survey Weeds—Fruit Development
By surveying weeds in late spring, you can identify any species that escaped previous control attempts and
determine what perennials are present. Weeds in tree rows must be managed, but annual weeds in row middles
may be beneficial. If herbicides were used, surveying identifies any need for changing to another herbicide.
Use the late-spring weed survey
form to
record your observations in order to make weed
management decisions. Keep
these records so that you can track weed population information
from year
to year to better understand
how weed populations change, problems with herbicide resistance,
and how effective your management operations have been over
the
long
term.
How to survey your orchard
- Survey your orchard in late spring or early summer, after summer annuals
have germinated.
- If you use cultivation for weed control, monitor at least 2 weeks before you plan to cultivate.
- Check for regrowth of perennials a few weeks after cultivation.
- Sketch a diagram of the orchard and mark areas where perennials are found.
- Keep records of your survey results. By knowing what species
are present, you will be able to make appropriate decisions
on cultural and chemical controls.
