Comparison of pre-emergent herbicides for annual ryegrass control in wheat at four locations across WA in 2016

To compare the efficacy of commercial pre-emergent herbicides and mixtures for ARG control across multiple soil types using grower machinery for seeding and ongoing management consistent with the grower’s practice.To determine yield and $ return on investment to the grower from current standard pre-emergent herbicides Sakura, trifluralin, Avadex Xtra and Boxer Gold with new options such as standalone prosulfocarb, the main component of Boxer Gold. Prosulfocarb (e.g. Arcade) must be incorporated within 7 days of application.

本试验针对多种土壤类型，采用贴合种植者实际作业流程的田间播种及后续管理所用农机设备，评估商用苗前除草剂（pre-emergent herbicides）及其复配制剂对ARG的防控效果。同时，本研究将测定当前主流苗前除草剂（包括商品名Sakura、氟乐灵（trifluralin）、Avadex Xtra及Boxer Gold）搭配新型制剂（如单独使用的Boxer Gold核心有效成分丙硫草特（prosulfocarb））时，可为种植者带来的作物产量与投资回报率。需注意，丙硫草特（例如其商品名Arcade）需在施药后7日内完成土壤混拌处理。
