Abstract
The invention relates to a field weeding composite of wheat. The field weeding contains clodinafop-propargyl and triclopyr used as effective ingredients and auxiliary components which can be accepted in pesticide, and the weight ratio of clodinafop-propargyl to triclopyr is 1:1 to 1:60. The composite of the two effective ingredients has synergism, and can be used to prevent and kill off various annual grassy weeds and broadleaf weeds and remarkably enhance the weeding effect.
Description
technical field [0001] The invention relates to a herbicide composition, especially a herbicide composition used in wheat fields. Background technique [0002] The trade name of clodinafop-propargyl is the top and also called Maiji, and the common name in English is Clodinafop-Propargyl. The chemical structure is as shown in formula (I). An excellent variety of herbicides, with high efficiency, low toxicity and low residue, it can effectively control many grass weeds such as wild oats, ryegrass, rye grass, etc. Safe for subsequent crops. [0003] Triclopyr, whose chemical structure is shown in formula (II), is a pyridyloxyacetic acid compound and is a selective systemic herbicide, which is absorbed by weed leaves and roots and transmitted to the whole plant, acting on nucleic acid metabolism , Excessive nucleic acid is produced, some tissues are transformed into meristems, resulting in abnormal growth of leaves, stems and roots, depletion of storage substances, embolism or...
