Scope

This document specifies the monitoring methods, critical prevention periods, and pesticide prevention methods for the control of Uroleucon gobonis (Matsumura) on saffron. This document is applicable to saffron production in Ningxia. 3 Terms and Definitions There are no terms or definitions that need to be defined in this document. 4 Monitoring Methods The morphological characteristics and occurrence patterns of Uroleucon gobonis are described in Appendix A. According to the distribution of saffron planting, a "checkerboard" sampling method is used to set up fixed monitoring points. Starting from mid-to-late May before the saffron buds appear, surveys are conducted every 7 to 10 days. At each sampling point, 2 plants are selected, and the number of Uroleucon gobonis on the topmost shoots within 20 cm of 5 branches is investigated. 5 Critical Prevention Periods The critical prevention period is from the end of May to the beginning of June before the saffron buds appear. 6 Pesticide Prevention Methods The recommended pesticide application methods in this document are all spray applications. The dosages of pesticides for controlling Uroleucon gobonis are listed in Table 1. The safe use of pesticides shall comply with the relevant provisions of GB 2763, NY/T 1276, and NY/T 393.
