T/ZYNY 013-2023 Plant-based nematicide against root-knot nematodes

Scope

Scope: This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, etc. for extracting root-knot nematodes from plant sources. This document is applicable to the production of root-knot nematode control agents primarily made from plant-derived extracts. Main technical content: 1. Technical requirements: The technical requirements shall comply with the specifications in Table 1. Table 1: Specifications for extracting root-knot nematodes from plant sources. Appearance (25℃) Solid content (%) pH value (1% aqueous solution) TH-2 Light yellow to dark brown liquid ≥55.0 - 7.0 2. Determination of solid content: Use a pre-weighed flat weighing bottle (with a weighing error of ±0.0004g) to weigh 2g of the sample (weighed to an accuracy of ±0.0004g) and place it in an oven at a temperature of 100℃-105℃ until it reaches a constant weight (with a weighing error of ±0.0004g). The solid content is calculated according to the following formula: G2-G1X(%) = 100 - ────×100G Where: G -- Weight of the sample, g G1 -- Weight of the weighing bottle and the sample after drying, g G2 -- Weight of the weighing bottle and the sample before drying, g
