Abstract
The invention relates to a synergetic herbicidal composition, and particularly relates to a novel compounded herbicidal composition which is a ternary compounded system including pyribenzoxim, carfentrazone-ethyl and pyrazosulfuron and is used for rice fields. The synergetic herbicidal composition comprises herbicidal effective amounts of (a) pyribenzoxim, (b) carfentrazone-ethyl and (c) pyrazosulfuron, wherein a weight ratio of the three active components (a) to (b) to (c) is 1-100 : 1-100 : 1-100. The synergetic herbicidal composition also can comprise a safety agent. Through ternary compound of pyribenzoxim, carfentrazone-ethyl and pyrazosulfuron, the obtained novel composition can effectively overcome the defects that pyribenzoxim is used individually, enlarge herbicidal spectrum for weeds and delay the generation of resistance. The weeds in rice fields can be largely eradicated by applying the synergetic herbicidal composition at one time. The synergetic herbicidal composition is labor-saving, time-saving and effort-saving, thereby relieving labor crunch in rural areas, and has a certain effect for increasing both production and income for the rice. An enhanced effect in prevention of broad leaf weeds, grassy weeds and cyperaceae weeds in the rice fields is obtained.
Description
Technical field [0001] The present invention involves a coordinated weedian composition, especially a pyrimidine molt ether and azolone and pyrazone sulfuron triple relics, and a new type of re -weeding sanctuary applied to rice fields. Background technique [0002] Rice is one of the main food crops in the world. Nearly half of the world, including the population of almost the entire East and Southeast Asia, use rice as a food and produces all continents except Antarctica.In the early stages of the last century, the average annual output of rice rice was about 400 billion kg, and the planting area was about 145 million hectares.Rice in my country is also the most important food crop.my country's rice breeding noodles account for one -third of the national grain crops, about 35 million hectares each year, and the output accounts for more than half.Regardless of the planting area and yield, it ranks first among my country's grain crops. [0003] There have always been a lot of wee...
