Inclusion of maize in the dairy ration has long been favoured by many dairy farmers and with the current costs of other crops and inputs, 2022 represents an even better opportunity for maize.
When growing high yielding varieties, often other agronomic features such as disease resistance are sometimes overlooked. The fungicides at our disposal today are capable of producing extremely good results, but it is important to apply as much thought to the fungicide programme and timings as to the choice of product, to achieve optimum yield potential.
Over recent years, the emphasis has moved away from reactive fungicide applications to treat visible disease in the crop, and more towards a strategy where prevention is better than cure. To achieve this, the fungicides must be applied at the correct time and early in the development of the disease, or even before infection occurs, with timing infl uenced by growth stage, weather and the variety’s disease resistance.
When it comes to producing good quality, nutritious silage small things can make a big difference. This is especially true of mistakes. A shortcut or a small oversight can ultimately result in silage that is unusable due to insufficient dry matter content or worse, silage that is dangerous to herd health because of mould growth and the likely presence of mycotoxins or Listeria.
Many farmers have come to accept some issues, particularly with mould, as inevitable and as a necessary evil. The reality is however, it's all too often caused by someone committing one of a number of silage "sins".
For cost-effective weed control in root crops the emphasis must be placed on pre-emergence application of herbicides. Every year we receive a large number of calls from concerned growers who have applied no herbicide at all and who are concerned that their root crop is disappearing under a sea of weeds. By this point, it is usually too late to save the crop!
Grassland management is often overlooked for new leys, but by prioritising weed control early during establishment, you will achieve cost-effective, long-lasting control, resulting in higher yields of grass.
Top questions to ask yourself this March to maximise the potential of your maize crop. Have you carried out soil analysis to identify nutrient shortcomings that could hamper the crop’s performance?
The timing of nutritional inputs to the maize crop is usually early in the season, either applied to the seedbed pre-drilling, or early post-emergence up to the 4- 6 leaf stage.
KORIT®PRO is a new unique seed treatment combination for maize being offered by Limagrain. The treatment has three modes of action, and unlike the standard Korit, which only offers a measure of bird repellency, the new Korit Pro also includes additional fungicide protection, it boosts root development and improves crop emergence.
Growers are being urged to monitor maize crop nutrition throughout the growing season, to make sure they reach their full potential.
Dr Simon Pope, Wynnstay crop protection manager, says ideally the nutrient inputs for sowing and establishment will already have been applied, and plans should be made regarding the maize crop nutrition throughout the rest of the season.
The last three maize seasons have had the same result – a mixed bag of performance depending on region, drilling date and harvest timings. However, in 2020, growers had a new challenge to contend with.
The removal of the maize seed treatment Mesurol left a hole in the crop protection armoury, resulting in crops being at greater risk from bird damage, which in previous years would not be high on the list of issues for most growers.
