“Chestnuts roasting on an open fire,” is a line from a song that conjures up fond holiday memories for some Americans. For others, the joy of roasting chestnuts has yet to be experienced. But the lack of American chestnuts could change in the coming years, thanks to some very dedicated people.
Palmer amaranth has caused corn, soybean and cotton farmers a world of trouble.
Now, tobacco farmers may be in danger of a big loss due to the weed.
Bed bugs and head lice are the two insects that will most commonly send people into a sudden shudder, just from the thought of an infestation. Head lice seem to make a resurgence around the holidays, especially in schools. However, not many people are as well-versed in what to do about head lice, or even about the truths about lice. An article in the Washington Post has some facts–and debunks seven of the most common myths–about head lice.
It’s a tough fight, but there is no reason for Palmer amaranth to kick a soybean grower’s butt.
Some growers continue to struggle, but soybean farmers now have the tools to win against it. So how can farmers not lose against pigweed? Two Southeast weed specialists have good game plans.
Even though the tail end of harvest for this year is in sight, it’s never too early in Georgia for farmers to get pigweed strategies lined up for next year’s row crops, including soybean. Get a good plan and stick to it as best able, said Eric Prostko, weed specialist with the University of Georgia Cooperative Extension.
“As it has been said before ‘the devil is in the details,’” Prostko said. “In my opinion, there are three details that growers must use if they ever expect to get a handle on Palmer amaranth control.”
No. 1: Start clean. You will lose if you plant soybeans into a stand of Palmer amaranth. Till it, burn it down with herbicides or use rye cover crops, but start Palmer–free. If there will be a long delay between tillage and planting, use of a residual herbicide to prevent Palmer emergence during that time period.
No. 2: At least one or even two residual herbicides will be needed for the season. “Sadly, the good old days of just spraying glyphosate or Liberty are over (in Georgia),” he said. “There are many effective residual herbicide choices.”
Authority MTZ, Boundary, Canopy, Dual Magnum, Envive, Tricor, Warrant and Valor all work. “I would prefer herbicides like Reflex or Prefix be applied postemergence. These are the only over-the-top herbicides that will control small emerged Palmer plants and provide residual activity,” Prostko said.
Even if a farmer uses a LibertyLink soybean system, he still needs a residual herbicide. But a residual is only good if it can be activated timely with irrigation or rain. If not activated, the soybean farmer will lose against pigweed.
No. 3: Postemergence herbicide application must be made before the biggest pigweed hits 3 inches. If the plants are bigger, well, you know, a farmer will lose against pigweed. Scout fields once a week or more, he said, and do it from outside of the truck.
“My greatest wish is that I never again receive a phone call about how to control 12-inch Palmer amaranth in soybeans. That is a question for which there is no answer. … Palmer amaranth control does not have to be the major management issue. I will be the first to admit that it is not easy.”
Two weevil species, the bluegrass billbug and the hunting billbug, have caused widespread economic damage to orchardgrass, a cool season grass that is cultivated throughout the United States as a high-value forage crop.
