Scope

This document specifies the terms and definitions, control targets, control techniques, and evaluation of control effects for the prevention and control of major pests in alfalfa fields. This document is applicable to the Ningxia Hui Autonomous Region. 3 Terms and Definitions The following terms and definitions are applicable to this document. Alfalfa Pest Ecological Regulation Based on the theory of plant volatile substances, pest attraction, and push-pull control, by mixing different pest-resistant alfalfa varieties, intercropping alfalfa with functional plants, and creating habitats that are unfavorable for pest growth and population increase while providing shelters for natural enemies, the aim is to effectively regulate the population density of alfalfa pests. 4 Control Targets Alfalfa leafhopper (Therioaphis trifolii), pea aphid (Acyrthosiphon pisum), horned thrips (Odentothrips loti), common large thrips (Megalurothrips usiatus), grasshopper (Lygus pratensis), cotton bollworm (Helicoverpa armigera), sweet potato moth (Spodoptera exigua), and meadow moth (Loxostege sticticalis). 5 Control Techniques Control Indicators Follow the provisions of NY/T 2994. Investigation Methods Follow the provisions of DB64/T 1258. Control Methods 5.3.1 Agricultural Control Select pest-resistant alfalfa varieties; timely remove weeds in the field; and mow the grass about 7 days before mowing when the pest population reaches the control target. 5.3.2 Biological Control Follow the provisions of NY/T 2994. 5.3.3 Physical Control Sticky Board Traps Use yellow boards to trap alfalfa leafhoppers and pea aphids, and blue boards to trap horned thrips and common large thrips. Place the traps so that the lower edge of the board is flush with the top of the plant, and adjust the hanging height as the plants grow; hang 20–30 pieces of 25 cm × 30 cm or 35–40 pieces of 20 cm × 30 cm sticky boards evenly across 667 m2 during the pest outbreak period.
