Residual Control of Summer Grasses in Wheat locations
Aims

To evaluate herbicides for the residual control of feathertop Rhodes grass in wheat

Key messages

This trial was established to evaluate the residual control of Feathertop Rhodes (FTR) grass in wheat. Stubble levels were extremely low with the paddock long fallowed from sorghum in 2019/20.
The majority of treatments were applied 3 days prior to planting (-3 DAP) and incorporated by sowing (IBS) using a commercial disc planter on 28cm row spacing. The post sowing pre-emergent treatment (PSPE) was applied 4 days after planting. No rainfall was recorded between the IBS and PSPE applications with ~24 mm recorded in the first 9 days after the PSPE application. The in-crop application was applied at a crop stage of 2-4 tillers, 57 days after planting (57 DAP) and received ~11mm of rain the following day.
A total of 175mm was received during the 5-month duration of the trial. Monthly totals of less than 10mm of rain were recorded in August and September with a total of ~65mm in October.
Wheat establishment was assessed at 18 DAP with ~104 pl
