Problems solved by technology

With the large-scale use of herbicides in the field for many years, from the actual effect, the following problems have appeared in the control of field weeds: prominent weed resistance, difficult to eradicate perennial weeds and short duration of soil control agents And other issues
Traditional chemical herbicides play a role in screening weeds for resistance, which not only reduces the weeding effect, but also causes new environmental pollution to soil, crop fruits, groundwater sources, etc.

Abstract

The invention belongs to the technical field of weeding, and particularly relates to a preparation method of a composite field herbicide. The herbicide disclosed by the invention is prepared from thefollowing components in parts by mass: 10-20 parts of cyhalofop butyl, 1-5 parts of metolachlor, 1-5 parts of oxyfluorfen, 1-3 parts of ZumSil, 1-3 parts of dimethachlon, 5-7 parts of green tangerinepeel oil, 8-10 parts of thifensulfuron-methyl, 10-25 parts of pretilachlor, 5-15 parts of budding stopping agent, 6-8 parts of carbamate, 6-8 parts of an aromatic hydrocarbon organic solvent, 3-5 parts of a surfactant, 2-4 parts of a synergist, 1 part of a safener, 5-15 parts of a Trifolium repens extracting solution, 3-9 parts of quick lime and balance of vegetable oil. Cyhalofop butyl is adoptedas a main material of the herbicide, has high safety to various field mainstream crops such as rice, has a strong removal effect on main gramineous weeds in the field, can prevent and remove digitaria sanguinalis, paspalum distichum, setaria viridis, eleusine indica, alopecurus amurensis and the like, and has the characteristics of broad spectrum, strong selectivity, convenience in use and the like.

Description

technical field [0001] The invention belongs to the technical field of weeding, and in particular relates to a preparation method of a compound field herbicide. Background technique [0002] Because field weeds have the characteristics of large population, wide adaptability, wide vitality, and strong vitality, in order to reduce the harm of farmland weeds and ensure the safe growth of crops, chemical weeding is one of the important means in the comprehensive prevention and control of farmland weeds. With the large-scale use of herbicides in the field for many years, from the actual effect, the following problems have appeared in the control of field weeds: prominent weed resistance, difficult to eradicate perennial weeds and short duration of soil control agents And other issues. Traditional chemical herbicides screen the resistance of weeds, which not only reduces the weeding effect, but also causes new environmental pollution to soil, crop fruits, groundwater sources, etc...
