Scope

Scope: This document specifies the terminology and definitions, experimental methods, investigation and recording, evaluation methods, and experimental results for evaluating the sensitivity of sugarcane to herbicides. This document is applicable to the evaluation technology of sugarcane's sensitivity to herbicides; Main technical content: 4 Experimental methods 4.1 Variety selection: Selected varieties of sugarcane that have been widely planted or new sugarcane strains with potential for promotion. Record the name, source, and seed storage time of the tested varieties. 4.2 Experimental design 4.2.1 Field experiments 4.2.1.1 Experimental site: Field experiments were conducted in the main sugarcane-growing areas. All experimental plots must have uniform cultivation conditions (soil type, terrain, fertility, and tillage), and the previous crops should not have been treated with long-residue herbicides. Record the type, time, and frequency of herbicide application in the previous crops. 4.2.1.2 Sugarcane planting: Selected fresh, intact, and disease-free sugarcane shoots were used as seedlings. The seedlings were cut into 2-3 bud segments and disinfected with a 50% Multisporin solution at 500-1000 times dilution for 10-20 minutes. The seedlings were planted in a herringbone or railroad-style double row arrangement, with a covering layer of 3-5 cm of soil after planting. The seeding rate was 75,000-90,000 buds per hectare, and the seeding rate was consistent across all experimental plots. The experimental plots were arranged in randomized block design, with a plot area of no less than 30 m2 and at least 4 replicates. 4.2.1.3 Herbicide preparation: Herbicides were selected as either pure products or formulations, and were prepared at four concentrations: the registered recommended minimum dose, the recommended dose, and twice the recommended dose. A control treatment with no herbicide was used. The preparation methods for different herbicide concentrations
