Problems solved by technology

[0003] In 2009, pinoxaden was temporarily registered in my country, and was officially registered at the end of 2010. It is used to control gramineous weeds in winter wheat, spring wheat and barley fields. Due to the large planting area of ​​crops in China, the usage of pinoxaden in China However, pinoxaden is limited by patent protection and has not yet been fully developed in the domestic market. The pinoxaden patent is valid until 2018. However, there are very few domestic reports on pinoxaden rapid detection technology, and domestic A quick and easy detection technique has not been established, so it is particularly necessary to develop a rapid method for pinoxaden in crops on LC-MS / MS

Abstract

The invention discloses a method for rapidly measuring the content of oxazoline in crops, comprising the following steps of: Step a: preparing a solution; Step b: pretreating the crop sample; Step c:measuring the sample; Step d: analyzing and calculating. The method for rapidly detecting the content of oxazoline in crops provides a reference basis for the pretreatment of the sample by rapidly designing the pretreatment of the sample in the crop by the design of the pretreatment method of the crop, and detects the content of the oxazoline in the crops accurately through the design of the rapiddetection method.

Description

technical field [0001] The invention belongs to the technical field of detection of agricultural residues in grains, and in particular relates to a method for rapidly detecting the content of pinoxaden in crops. Background technique [0002] my country is a large crop-growing country. Pinoxaden is a new phenylpyrazoline herbicide, which also belongs to the acetyl-CoA carboxylase (ACC) inhibitor herbicide class. Pinoxaden is mainly used for the control of annual grass weeds in wheat and barley fields, against grass weeds such as wild oats, ryegrass, foxtail, hard grass, chrysanthemum, kangaroo, Japanese kangaroo, and clubhead grass It has good control effect, especially close to 100% control effect on some vicious grass weeds such as wild oats, ryegrass, hard grass and chrysanthemum. In addition, it is relatively safe to wheat and barley, and has a wide application period. Therefore, the usage of pinoxaden has gradually increased. [0003] In 2009, pinoxaden was temporarily...
