Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of rice post-emergence complex weedicide containing propanil.
Background technique
Rice is not only one of most important cereal crops and world's staple food crop in China.In the world nearly one
Half population, the population including almost entire East Asia and Southeast Asia are all food with rice；It is produced also throughout each in addition to the South Pole
Continent.No matter cultivated area and yield, all rank first in China cereal crops.The rice field of all rice workspaces in China, always
There are a large amount of weeds.Medium crop smothering area accounts for 46% or more of total cultivated area, wherein serious injured area 11.5% with
On, thus annual more than 200 hundred million kilograms of grain of loss.Therefore, the use ratio of domestic herbicide for paddy field nearly reaches 100%,
Its dosage is very big.
Barnyard grass in paddy field is the important crop smothering of paddy field.Barnyard grass, Classification system: Echinochloa crusgalli (L.)
It Beauv., is a kind of annual herb plant, barnyard grass and rice shape are very much like.Barnyard grass grows in rice field, marsh, irrigation canals and ditches
Other, low-lying wasteland.Shape like rice but blade hair it is puckery, color is shallower.Barnyard grass and rice absorb nutrient in rice field, therefore barnyard grass jointly
Son is the malignant weed in rice field.There are barnyard grass in South And North Rice Regions, develop into multiple product such as red stalk barnyard grass, green barnyard grass, rice barnyard grass, river barnyard grass at present
Kind.
