Hand-rouging and pulling late season weeds by hand may be the best way to remove them, more so than using a herbicide, a Purdue Extension weed scientist says.
Simply attempting to control Palmer amaranth often leads to ineffective herbicide applications, substantial crop yield loss, and increased weed infestations, says a University of Illinois weed scientist.
The enhanced formulation has improved viscosity and increased stability under heat and controls more than 60 high-anxiety grasses and broadleaf weeds found in corn fields.
BASF has invested more than $270 million to expand herbicide production capacities in the U.S., including more than 20 new products to be launched over next two years.
The Provisia Rice System will provide a new tool for post-emergence control of a broad range of grass weeds, including ALS-resistant grasses, weedy rice and red rice.
BASF suggests a post-emergence herbicide with residual control before weeds reach four inches in height as the best way to tackle tough to control weeds after they have emerged.
Within the Acuron signature, four inverted triangles adjoin to create a star. Each triangle represents the herbicide’s four active ingredients, including new bicyclopyrone.
Many herbicides are still safe for farmers to use after corn has emerged so long as they pay close attention to product selection and application timing, according to Purdue Extension weed scientists.
Typically, soil-applied herbicides control target weed species with little to no adverse effect on the crop. However, there are some factors that can contribute to herbicide-induced soybean injury.
The Weed Science Society of America (WSSA) has announced plans for a second national scientific summit on the topic of herbicide resistance in Washington, DC, in September.
Field studies show that a fall application of certain herbicides before weed emergence, leads to more successful crop planting and weed control in spring.
Palmer amaranth has prolific seed production, rapid dispersal, and high competitiveness with crops, making herbicide-resistant strains difficult to control.
