Weed Scouting Aid


Horizon Point Weed Scouting Aid

This information should be used as a general guide to aid in weed scouting and weed management decisions. These calculations are based on the ambient air degree days accumulated since January 1. Additional factors, such as the soil type, amount of rainfall received, and the presence of crop residue will have a significant impact on the likelihood of weed emergence in a given situation.

The following weeds could have emerged in your area recently:

Common lambsquarters,   pennsylvania smartweed,   common sunflower,   giant ragweed,   woolly cupgrass,   common ragweed,   velvetleaf,   giant foxtail,   field sandbur,   yellow foxtail,   common cocklebur,   shattercane,   black nightshade
 
The following weeds could be emerging in your area by the date given.
 

Weed Emergence Table
Calculations based on growing degree days.
 Weed Emergence
 Wild-proso millet 4/21/2020
 Large crabgrass 4/21/2020
 Morningglory species 4/21/2020
 Witchgrass 4/23/2020
 Fall panicum 4/23/2020
 Common/Tall waterhemp 4/28/2020

The information above will be included in your daily report.

The weed scouting aid is composed of 2 sections. The first section lists weeds that could have emerged in your area already depending on the number of growing degree days that have occurred for your area. Particular attention should be given to these weeds while scouting. The names of individual weed species will stay on the report until it is expected that a majority of that species has emerged, and then they will be removed.

The second section estimates when weeds will emerge in your area based on the actual number of growing degree days that has occurred and the normal number of growing degree days that is expected to occur in the future. The emergence date indicates when 10% of the weeds of that species are expected to have emerged.

After all the weed species have emerged, the weed scouting section will not appear on reports even if the subscriber has selected to receive them.

Weeds listed in the report are linked to pictures of the emerging weeds to aid you in identification of the weeds.
