LettuceSurvey for Weeds—PreplantStart surveying your fields for weeds before harvesting the preceding crop. Determine the dominant weed species present, and maintain records of weed species and the severity of their infestations. Also, check weed infestations in adjacent fields. Depending on when you monitor, you may see winter annual seedlings, summer annual seedlings, or perennial weeds. Weed surveys can help you select herbicides, rotational crops, and cultural practices. How to survey your field
Survey information collected over a period of years tells you how weed populations may change and how effective your management operations have been over the long term. By knowing which species are present, you will be able to make appropriate decisions on cultural and chemical controls.
