As the calendar moves through the summer months and postemergence herbicides are applied to late-planted crops, it's a good time to review some research on the effects of high temperatures on Group 27 herbicides.
University of Nebraska-Lincoln greenhouse studies have confirmed a Palmer amaranth population resistant to postemergence application of atrazine and HPPD-inhibiting herbicides (Callisto, Laudis, Armezon/Impact). This is the second report (after Kansas) of a Palmer amaranth population resistant to atrazine and the HPPD group of herbicides.
The first confirmed case of weeds resistant to HPPD-inhibiting herbicides has been found in waterhemp in Illinois, according to University of Illinois weed scientists.
New products are mostly refinements of old standbys and recent successful introductions. Manufacturers are emphasizing convenience and market competition.
No-Tillers planning for the 2004 growing season can look forward to a handful of new alternatives for protecting their corn from weeds and insects. Herbicide and insecticide manufacturers and seed producers introduced their new products to attendees at the National No-Tillage Conference held in Des Moines, Iowa, in January.
While Hypoxia has been a serious issue for a half dozen years in the Gulf Of Mexico, pollution and sediment left nearly half of the Chesapeake Bay so depleted of oxygen this summer that it couldn’t sustain aquatic life.
Since herbicide-tolerant transgenic cotton varieties became widely available in 1997, the no-till cotton acreage has nearly doubled in the United States. A recent survey by the National Cotton Council indicates that no-till made up 29 percent of total cotton acres while reduced tillage made up 30 percent of all cotton acres in 2002.
With fewer new herbicides coming on the market each year, no-tillers are paying much closer attention to developing more effective weed-management plans. As a result, no-tillers are intently studying how various herbicide and tankmix combinations perform in their fields.
