Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of mixed herbicide containing propaquizafop and flufenacet and its answer
With.
Background technique
Propaquizafop category aryloxyphenoxypropanoates class selective herbicide is acetyl-CoA carboxylase (ACCase) inhibitor,
It is absorbed quickly by grass cutting blade after cauline leaf process, conduction to entire plant, accumulation inhibits acetyl in weeds body auxiliary in separate living tissue
The activity of enzyme A carboxylase leads to fatty acid biosynthesis block to kill weeds.It is mainly used for preventing and kill off numerous annual and many years
Raw gramineae weed, it is best in weeds Seedling Stage and growth period application preventive effect.
Flufenacet is aromatic amides herbicides, main by inhibiting cell division to play a role with growth, at present
Numerous annual gramineous weeds can be effectively prevented and kill off, such as Itanlian rye, herba digitariae, herba eleusines indicae and certain broadleaf weeds
It early stage before seedling and after seedling, can be before planting or before seedling for before corn field and soybean field weeding, potato plantation or potato, sunflower
Seedling before weeding and wheat, barley, rice, seeding corn and other crops postemergence weed control.
Compounding between herbicide not only can solve the problem that pesticide single dose toxicity is big, effect is poor, but also less investment, R&D cycle
It is short, and it is used interchangeably the generation for capableing of retarding action object drug resistance between different pesticides, it is imitated with ideal use
Fruit, therefore the compounding of pesticide is current research focus in the field of pesticide between different role mechanism.It will not dislike in the prior art
