T/NAASS 101-2024 Technical Specifications for Field Efficacy Test of Insecticides against Wolf Spiders in Wolfberry Fields

Scope

Scope: This document specifies the methods and basic requirements for field efficacy trials of insecticides against wolf spiders in wolfberry plantations. This document is applicable to field efficacy trials of insecticides against wolf spiders in wolfberry plantations. Main technical content: 3. Terms and definitions: There are no terms or definitions requiring definition in this document. 4. Test objects: Wolfberry wolf spiders: Bactericera gobiaca (Loginova), belonging to the family Hemiptera, subfamily Tingidae. Symptoms of damage are described in Appendix A. 5. Selection of test sites: Wolfberry plantations with frequent occurrence of wolf spiders and moderate or severe damage should be selected. The cultivation conditions (such as soil type, fertilization, planting spacing, etc.) and tree ages of each test site should be consistent. Field management should follow local conventional practices. 6. Test agents: 6.1 Test agents should be labeled with their common name (Chinese name) or code, trade name, dosage form, content, manufacturer, and treatment dose (effective ingredient dosage in mg/kg or effective concentration in mg/L). At least three doses or as required should be used for test agents. 6.2 Selection of control agents: Registered products with proven good efficacy in practice, whose types and modes of action are similar to those of the test agents, should be selected and used at local conventional dosages. If the test agents are single agents, at least one locally commonly used single agent should be used as the control agent; if the test agents are compound agents, each single agent in the compound should be used as the control agent, and another locally commonly used agent should also be used as the control agent. 6.3 Blank control: No agent treatment (treated with an equal amount of water) should be used as the blank control. 7. Test design: A randomized block design with four replicates and a plot area of 25–30 m2 should be used, with 8–10 trees per
