Rapid, uniform germination and emergence of corn help set the stage for maximum grain yield at the end of the season.
Rapid, uniform germination and emergence of corn help set the stage for maximum grain yield at the end of the season.
Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place.
Scouringrushs and horsetails are known by many different common names such as snake grass, jointed grass, monkey grass or simply Equisetum to name a few.
Every spring we receive several calls and e-mails about a certain 3-foot tall weed with yellow flowers (Figure 1).
Night time and early morning temperatures across Indiana dipped to lows (less than 28oF) on Wednesday and Thursday that may be concerning to alfalfa producers. Damage may be little to none, or possibly severe. Minimal damage may appear as new leaves emerging next week being bleached. Whereas, severe damage will have the plant losing its upright integrity and appearing water soaked (mushy). New seedlings will take on a water soaked appearance if freeze damaged. Variation in response could be extreme across a field due to differences in temperature because of topography. Older stands that were well managed last year will have a greater chance of survival. Please contact me at johnsonk@purdue.edu if damage is severe because of the freeze events.
2019 Black Cutworm Pheromone Trap Report Form
Armyworm Pheromone Trap Report – 2020
Last week’s articles were concerning the eye-popping numbers of black cutworm and armyworm moths being captured by pheromone trap cooperators and weevil damage being reported in southern Indiana alfalfa fields.
Pest managers, in southern Indiana, should now be scouting their alfalfa for leaf feeding from weevil larva.
While the coffeeshop rumor mills were active this past week with talk of “a lot” of corn planting going in areas of the state, in reality very little planting actually occurred (USDA Weekly Crop Progress, 13 Apr 2020).
