Kerb Weather Data - Final Report - week ending 16th November 2012Follow @DOWAGROUK
Where travelling is possible, soil temperatures are now favourable for maximising efficacy of Kerb* Flo 500 applications. Crop selectivity for propyzamide is by depth protection of the roots. Applications to very small oilseed rape plants can cause problems such as stunted growth with leaves fused to the axil or stem and yield depression. Once a crop has reached the three true leaf stage the roots are at sufficient depth to not take up a dose of propyzamide that could cause problems. Some judgement may be needed in backward crops as to the risks on any smaller plants and on shallow rooted areas. Applications of Kerb Flo 500 may be made to 31st January. In order to maximise the efficacy of Kerb Flo 500, we recommend applications are made when soil temperatures fall to below 10°C and where there is sufficient moisture in the soil for plant uptake.
This autumn has been challenging and optimal weed control will be vital in order to maximise yield potential and financial returns from late drilled, backwards crops. Download our current topic sheet for more information. If spray days are limited this autumn, growers can maximise spray efficiency with the new Kerb Flo 500 formulation:
We support a range of herbicides and fungicide tank mixes - Download the Tank Mix List for Kerb Flo 500 Open, backward crops and missed herbicide applications have resulted in some crops with broad-leaved weeds such as mayweeds and thistles. Kerb Flo 500 may be applied in tank mix with Galera* from 4 true leaves. Water Stewardship In a season where levels of metaldehyde in the water are receiving a lot of attention, water stewardship needs to be top of mind to safeguard the environment and protect products from withdrawal. If you can travel, applications of Kerb Flo 500 must only be made after taking all necessary precautions to avoid contaminating surface waters. Kerb Flo 500 may be applied in frosty conditions but avoid application onto frozen ground where subsequent rainfall could result in run-off into watercourses.
