"Damage to sowing by trustees herbicides has become a more serious problem throughout North Carolina. Farmers, seeing low-spirited plants with deformed leaves, fear that herbicidal injury will lead to a crop loss. - tells John Hart in his article on the portal www.farmprogress.com.
For the most part, such injuries are cosmetic character and do not harm crop, says Wes Everman, arising, mainly on weather reasons.
"Cool weather and humidity are always aggravated by injuries from predatory products, because plants cannot grow well and split herbicides. When cool, everything slows down. Even we are braked. Cool in the morning is moving not as fast as usual, "explains Everman.
"In general, in most cases, we observe how the plant will safely convert this injury as the cultivation conditions improve. If this is a temporary cooling or rain period, after which the water dried and the heat is warm, the temperature rises, the plant comes back to normal. Metabolism will work, and we will not see any effect from this injury from the point of view of growth and yields in the future, "said Everman.
The expert noted that all promenof herbicides can cause damage to crops. As a rule, injuries do not arise in ideal conditions, being mainly the problem of cool and wet weather and the flaws of the Agrarian themselves.
"We see herbicidal damage for a number of different reasons: the norm may be high. We may have overlaps of sprayers. Maybe more often, especially with strong rains in the spring, we can have the movement of the soil. Some herbicides stick to this soil a little stronger than others, and they can move along with this soil, "said Everman during a webinar to combat weeds.
Everman calls on farmers not to reduce the norms from the recommended to avoid herbicidal injury.
The reduced rate really reduces injuries, but also gives weeds more chances to survive. "
