Teagasc is strongly advising all cereal growers to walk crops now in order to identify problem weeds and plan future controls options
The challenge of herbicide resistant grass weeds continues to grow on Irish tillage farms at an alarming rate.
Given the threat of herbicide resistance, agronomists are strongly advising that grass weeds should not be allowed to develop seed heads.
Teagasc is working closely with the farmer on whose land the first Irish case of glyphosate resistance in Italian ryegrass has been found
Teagasc has said it is concerned after identifying the first case of resistance to the weedkiller glyphosate in Irish cropping systems.
The Weed Resistance Action Group (WRAG) has confirmed the first case of glyphosate resistance within a weed population
Securing effective autumn weed control in newly established cereal crops is crucially important if optimal yields are to be secured
Teagasc is confirming that the challenge of ‘uncontrollable grass weeds’ within crops remains a major challenge for tillage farmers.
Teagasc is confirming that the threat of herbicide resistance in blackgrass, Italian ryegrass and spring wild oats is now very real.
According to crops specialist at Teagasc, Shay Phelan, blackgrass plants have already started to flower in some cereal crops...
It is now evident that an insufficient glyphosate application rate for a specific weed species can increase problems with grass weed control.
