After what turned out to be a difficult harvest, harvest 2020 is almost complete with the exception of the remaining bean crop still to be harvested. Farmer’s attention will now turn to preparing ground for the planting of winter cereal crops. Farmers have begun to sow winter crops earlier this year in an effort to avoid the problems that were encountered last autumn. Early sowing of winter cereals from mid to late September usually ensures that farmers can prepare good seedbeds for planting and temperatures are much more favourable to promote fast germination rates and a greater number of plants established.
- Early sowing although has benefits is often associated with creating disease and pest problems which can inhibit the profitability and yield of crops.
- Earlier sown winter cereal crops have an increased risk of lodging later on in the crops life cycle, Take all, foliar diseases, problematic grass weeds such as brome and blackgrass, aphids and BYDV.
- The planting of winter cereal crops later in the year in the month of October does significantly reduce the risk of BYDV when compared with September planting.
- Farmers should plan to sow all heavier land and any land with a history of low pressure of BYDV and problem grass weeds incidence such as sterile brome and blackgrass, leaving the most vulnerable land until last to be planted.
- Identify fields with a history of problem weeds such as sterile brome and blackgrass and avoid sowing winter barley in these fields.
- The key germination period for sterile brome species and black grass is September and tapers of as sowing moves into October.
Drummonds can provide a number of tried and tested seed varieties for winter cereals with a choice of three different seed dressing to suit each farmer’s requirements.

Drummonds is one of Ireland’s premier seed assemblers and farmers can chose from three options of seed dressing.
Single Purpose dressed seed: (Kinto Plus) Gives the seed protection against all seed and soil borne diseases.
Radiate Dressed: (Zinc based) is an excellent seed dressing for promoting root establishment and growth. Increases yields on average between 0.4 -0.6 t/ha in our trials. With the increase in root mass, fertiliser utilisation is maximised which means the plant can cope better against stress e.g. drought and Take –All
Manganese Dressing: Benefit any soil that is deficient in manganese to ensure efficient and quick establishment.
Farmers who have sown oilseed rape should be now walking their crops of OSR to identify if slugs or the flea beetle are present in their crops. Cabbage stem flea beetle attacks seedlings and causes shot holing in the plants
Once cotyledons have unfolded, treatment for cabbage stem flea beetle and slugs should be considered if present (From the time the first leaf unfolds at GS10 to GS29). Karate (lamba –cyhalothrin) is generally the product of choice for CFB .
Post emergence herbicide:
- Should be applied when 6-8 true leaves are present
- Still time for Katamaran Turbo once the weeds are small
- ASTROkerb applied at 1.7 l/ha – Don’t apply until soil temperatures are below 10 degrees celsius
- From November through to January is the ideal timing for Astrokerb
- Volunteer cereal should be sprayed before the 2 leaf stage with a graminicde
- Clearfield varieties have a tolerance to cleranda.
- Cleranda is a co-form of imazamox + metazachlor
- Rate of use is 2l/ha + Dash 1l/ha (Dash is an adjuvant)
- Cleranda works best when applied to small actively growing weeds.
- Apply to a dry leaf.
- Avoid rain after application.
- Spray window is compromised if left to the end of October.
