Grass occurs generally, and species is various, occurs seriously in Huang-Huai-Hai summer corn crop smothering, crop smothering occurring area Zhan Gai areas cultivated area
82%～96%, wherein medium above hazard area is up to 64～66%.Maize at Seedling Stage is the most serious by crop smothering, in corn growth
Impact of the later stage weeds to yield is little.When Maize Seedling receives Weed infestation, plant is short and small, bar spire yellow, causes middle and late stage beautiful
Rice undergrowth, Severe Reduction.
With the development of agricultural cience and farming techniques, the popularization and application of chemical herbicide as saving of labor, save time, it is cost-effective
One of strong well stimulation.Mostly before seedling and after seedling two critical periods of early stage enter after broadcasting for the chemical prevention of corn field weed
OK, before the leaf phase of Semen Maydiss 2, medication is dangerous after 6 leaf phases for ordinary maize herbicide after seedling.At present, corn herbicide kind is more,
The wherein representative kind for having Control Weeds in Maize Field has nicosulfuron and mesotrione.But nicosulfuron is to having
A little corn varieties have poisoning, and mesotrione is good to corn safety, but less desirable to grassy weed effect.
