Cold stress negatively impacts plant growth, germination, and crop yield, especially when seeding in cold soil conditions.
Herbicide layering strategies involve combining multiple herbicide modes of action to target weeds effectively and prevent resistance development. This approach requires careful planning to apply different chemical classes at appropriate growth stages, ensuring comprehensive weed control while reducing selection pressure for resistant populations.
The more than 220-year-old tree was grown from a pip planted by Mary Anne Brailsford between 1809 and 1815. Its apples were discovered nearly 50 years later by local gardener Henry Merryweather in a garden owned by Matthew Bramley. Merryweather was given permission to take cuttings from the Bramley seedling as long as the apples he sold bore Bramley's name. Steven said her great-grandfather, Merryweather, believed in that apple, he commercialised it, he marketed it, he promoted it he called it the King of Covent Garden'.
More than 100 research studies show that soybeans typically suffer from a nitrogen gap when yields exceed 60 bu/ac. At that yield level, the combination of soil nitrogen and nodulation often doesn't provide what the plant requires to achieve higher yields. Could biologicals - including nitrogen-fixing endophytes and biostimulants - fill that "yield gap" and provide the nitrogen required at high yield levels? That's a question Syngenta Canada biological field specialist Greg Stewart has been working on for the past two years.
