Purdue specialist provides tips on 2010 weed outlookWEST LAFAYETTE, Ind. - It is never too late for farmers to start thinking about their 2010 weed control plan, according to a Purdue University specialist.
"The most common weeds to keep an eye on for 2010 are marestail, giant ragweed, common ragweed, common water hemp and volunteer Roundup Readyâ corn in soybean fields," said Bill Johnson, Purdue Extension weed specialist.
All of those weeds can be treated with a glyphosate and have occasionally survived control strategies.
"Although each farmer's situation is different, some basic strategies should help all producers," Johnson said.
First, farmers should note what weeds are common in their fields.
"Knowing what weeds were an issue for them in 2009 will give the producer a good idea of what is in store for 2010," Johnson said. "Each year you will have some variation between fields due to crop rotation, soil type and the local complex of weeds in the area. So each filed should be observed and managed as if it contains its own set of weed problems."
Second, producers should develop a plan for the upcoming season.
"Farmers should look at the Weed Guide for Ohio and Indiana and also keep in contact with their chemical dealer to determine what herbicides will suit them best," Johnson said.
The Weed Guide for Ohio and Indiana is located at https://www.btny.purdue.edu/Pubs/WS/WS-16/WS-16.pdf
There also are many workshops and events between December and February where weed specialist will be on hand to answer questions.
"It is important for farmers to attend these workshops, because in the middle of the season they will have to make decisions on a daily basis. This is one way for them to stay informed and prepared for the upcoming season," Johnson said.
If farmers notice an excessive weed problem, Johnson suggests contacting their Extension educator or chemical dealer immediately to help with identification and control.
Johnson will be speaking more about weed topics at the Michiana Crop Conference on Monday (Nov. 30) in Shipshewana, Ind. A downloadable brochure and registration form is located at https://www.ag.purdue.edu/agry/dtc/
