Abstract

A mixed herbicide of wheat after seedling relates to a herbicide used in the fields of crops, comprising triasulfuron, fluoroglycofen-ethyl, a synergist, a safener, an emulsifier, a cosolvent and solvent. Triasulfuron, fluoroglycofen-ethyl, the synergist, the safener, the emulsifier and the cosolvent respectively account for 5-50%, 1-45%, 4-20%, 2-15%, 2-15% and 3-10% of the total mass of the herbicide, and the balance is the solvent. The herbicide of the invention has remarkable weeding effect which is obviously better than the weeding effects of two single herbicides and other mixtures. Meanwhile, the herbicide has wide spectrum of weeding and is capable of effectively preventing and removing annual grassy weeds and annual broadleaf weeds. In addition, the herbicide has long application stage and can be used in 2 leaf stage to jointing anterior lobe stage after seedling of wheat; and the herbicide has moderate residual duration, one-time application can prevent and remove the weeds in the whole growth and development period of the crops, without any effect on the following crops.

Description

Technical field: [0001] The invention relates to a herbicide used in crop fields, in particular to a compound herbicide for wheat post-emergence. Background technique: [0002] Wheat is one of the main food crops in northern my country, and it is also an important feed crop. Its perennial planting area reaches more than 30 million hectares, second only to rice. The area of ​​weed damage in my country's wheat fields accounts for more than 30% of the wheat planting area, of which 8% are seriously damaged, and the yield is generally reduced by more than 15%. Therefore, the area of ​​domestic wheat using herbicides reaches 100%, and its dosage is very large. At present, the medicaments used for post-emergence stem and leaf treatment of domestic wheat fields mainly include: tribenuron-methyl, thiasulfuron-methyl, dicamba, metsulfuron-methyl, huma, and dicamba, etc. Grass, or against broadleaf weeds. Because it has been used for many years, weeds will develop resistance to pes...
