1. Technical requirements Technical requirements should comply with the provisions of Table 1. Table 1 Required specifications for extracting root-knot nematodes from botanical sources Appearance (25°C) Solid content (%) PH value (1% aqueous solution) TH-2 Light yellow to dark brown liquid ≥5 5.0-7.0 2. The solid content is measured with a constant Use a heavy flat weighing bottle (constant weight error ±0.0004g), weigh 2g of the sample (weighing accurately to 0.0004g), place it in an oven, and bake it at a temperature of 100°C to 105°C until it reaches constant weight (constant weight error ±0.0004 g), the solid content is calculated according to the following formula: G2-G1 The weight of the sample, g; G2──The weight of the weighing bottle and the sample before drying, g.
