It’s Agronomy Monday, hosted by Shaun Haney and Kelvin Heppner — highlights:

  • Peter Johnson takes a few minutes from harvesting wheat to discuss soybean issues growers are seeing — late maturity, downy mildew, aphids and more, as well as western bean cutworm in corn;
  • Rob Saik, Agri-Trend founder and executive producer of the “Know GMO” film, discusses food marketing and where the film project is at;
  • Ontario environment minister Glen Murray is moving on, joining Calgary-based environmental think-tank, the Pembina Institute;
  • Sherrilyn Phelps of SaskPulse on whether desiccating is necessary with hot, dry weather quickly drying pulse crops down.

Join us for RealAg Radio every weekday — 4pm eastern on Rural Radio 147 on SiriusXM!

  1. Good show—I farm corn and beans just east of SIoux Falls, SD—I listen on satellite Rural Radio on iPhone, your show comes on after a popular agronomy show, “Ag PhD”, Regarding soybean aphids, the universities came up with the 250 aphids per plant threshold…way too many….you are already losing yield, The spray is cheap—$2 acre for the pyrethroid lambda cyhalothrin–AgPhd recommends spraying when you see a few on a leaf—they multiply fast—–if you want fast knock down, use combination of chlorpyrifos (Lorsban) and lambda cy—chlorpyrifos kills instantly, lambda cy has 7-10 days residual—that’s about $4 acre—-if you have lots of aphids, you want to kill them right away—-lambda cy takes 3 days

      1. Thanks for your reply—Heard you on Agri-Talk yesterday as you were down with the crop tour—I live east of Sioux Falls on Mn border—-April rain 3.1, May 2.6, June 3.5, July 1.3, and August 6.3 so far—-July was dryer—3 weeks in between rain, subsoil carried corn, but less rain in July probably affected corn yield—-we were 4 inches behind normal until All this August rain—-I forgot to mention about soybean aphids—-the Universities used 250 aphids per plant threshold back when the insecticide cost a lot more $10 acre and soybeans were $5-6 a bushel—-now the insecticide is $2-4 and beans $9 and up—makes more sense to spray sooner, aphids do lower yields and their piercing of plants lets in other diseases—–especially 250 per plant, way too many—under the right conditions when you see a few, they multiply fast—they like 77 degrees—spider mites like hot and dry—90 degrees and above.
