The term 'residual' applies to a number of herbicides that have a long lasting activity in the soil. These herbicides are often applied directly to the soil prior to planting crops, pre-emergent.
Much of the Western Australia's wheatbelt has experienced a very dry 2018–2019 summer leaving very little stored moisture at present (DPIRD, May seasonal report 2019). Yield potential varies signif
A new guide has been published to assist cereal growers to identify frost damage and consider crop management decisions.
Taking experimental measurements can be labour intensive and time consuming, in addition the methods chosen must be repeatable (regardless of operator) with small degrees of error.
In 2020 the Department is conducting over 300 Grains Research trials across the state from Kununurra in the north to Esperance in the south.
This page hosts the 2018 frost trial information, handy project resources and the frost severity maps (from August).
How late is too late to sow canola? What is the yield penalty from time of sowing (TOS) or late sowing? What is the estimated yield loss from delayed sowing of canola in WA?
Delayed seeding or emergence will shorten the growing season for wheat, reducing yield potentials.
Field research services (FRS) ensures the delivery of timely and efficient technical expertise to implement field research experiments across the Western Australian grainbelt.
One method of weed control is to remove weed seeds in the fallow, stubble and pre-sowing phase.
