Survey Weeds—Late Fall

Survey your orchard after the first rains of the fall, after winter annuals germinate. Monitoring weeds in fall helps identify any summer species that escaped the previous year’s weed control program; adjustments can be made to control these species in the next year. Fall monitoring will also identify any winter species that are emerging.

How to survey

  • Pay particular attention to perennials.
  • Check for re-growth of perennials a few days after cultivation.
  • Weeds in tree rows must be managed, but annual weeds in row middles may be beneficial as a cover crop.
  • Record your observations on the fall weed survey form (105 KB, PDF) and use the map to show areas of of problem weeds.

Also keep records of weed management actions including timing, rates, and dates of herbicide applications and cultivations. Survey information collected over a period of years tells you how weed populations may be changing and how effective yourUmanagement operations have been over the long term.
