Description
Technical field
The invention belongs to technical field of pesticide, more particularly, to a kind of Herbicidal composition for rice field.
Background technology
China's rice cultivation is with a long history, and region is wide, is one of View of World Rice main production country.In the 70-80 ages in 20th century
Chemical herbicide enters China, and the farmland weed to China prevents and kill off work and brings Gospel, and substantial amounts of labour is able to from heavy
Artificial weeding work in free.But meanwhile between past 25 years, sulfonylurea, amide-type and synthetic hormone class etc.
The rapid popularization of the selective herbicide of the similar mechanism of action and long-term a large amount of uses, some weeds product sensitive to all class medicaments
System by eliminating, less sensitive drug resistance plant due to gene selects act on and caused drug-resistant organisms type starts to rise rapidly
Sprawling.Occurs anti-dichloro quinolinic acid bion barnyard grass, anti-penoxsuam bion barnyard grass, anti-cyanogen after 2000 in rice terrace
Fluorine grass ester biological type moleplant seed etc..Wherein, come barnyard grass, bald barnyard, very popular actor or actress barnyard grass, blue or green barnyard grass resistance with barnyard grass population Chinese and Western particularly to dash forward
Go out, to existing mostly except barnyard grass herbicide kind is insensitive, turn into the dominant population in some areas, preventing and controlling are arduous.According to
Report that it is 123.47 to the resistance index of dichloro quinolinic acid to determine barnyard grass with pot-culture method under the pool of Zhejiang, this resistant biotypes weeds
The purpose prevented and kill off is extremely difficult to using barnyard grass agent such as dichloro quinolinic acid, bispyribac-sodium, penoxsuam, pretilachlor etc. is individually killed, this
Class bion resistant weed can slowly develop into dominant population, strive water with rice and strive fertilizer, paddy growth is had a strong impact on when density is big,
The underproduction that rice is different degrees of is caused, threatens the stability and development of China's Rice Production.
Metamifop (Metamifop), chemical name (2R) -2- [4- [(the chloro- 2- isoxazolyl benzenesulfonamides bases of 6-)] phenoxy group]-N-
