Farmers in the major States of grain production have to resort to harmful environmental practice deep plowing of fields to win with the problem of active growth "superweeds"that are resistant to herbicides and threaten productivity.
Resistance to glyphosate, the main component of the widely used herbicide roundup, led to the fact that farmers in the Midwest are struggling to restrain the invasion of weeds.
According to experts, it is necessary to develop a means of emergency controls to combat resistant to the herbicide weed in some areas. Especially active weed, which can grow on 1-2 inches in a day, it Palmer amaranth.
Farmers who face uncontrolled growth of weeds, must perform a deep ploughing, which removes the weeds, but may also lead to soil erosion and other environmental problems.
The farmers refused deep ploughing a few decades ago. But switched to intensive use of herbicides such as glyphosate.
The Ministry of agriculture of the USA has informed, that in 2013 70 million acres of farmland in the country have grown resistant to glyphosate weeds.
