Sonido

Reduce early pest damage in maize with Sonido (active substance: thiacloprid). It helps deliver healthy crops with high yields for both forage maize and anaerobic digester applications. Partner with MaisTer WG herbicide later in the season for effective broad-leaf weed control.

Quick facts & important recommendations

Quick facts

Sonido increases crop stand and early vigour by reducing wireworm feeding damage. It controls key maize pests, especially wireworm, on crops planted in good soil and weather conditions and with early vigour. In addition, Sonido has an excellent environmental profile including beneficial insects.

Composition: 400 g/l thiacloprid concentrated suspension for seed treatment (FS).

Dose rate: 125 ml/unit (50 g active per unit seed). Calculate your seed rate.

Registered crops: maize grain (silage and seed production) and sweetcorn.

Usage restrictions: none concerning crop rotation, succeeding crop and soil type.

Important recommendations

  1. Test all varieties to assess compatibility before commercial treatment with Sonido.
  2. Use Sonido only on high-quality seed lots showing strong emergence and vigour.
  3. We do NOT recommend co-treatment with Mesurol (methiocarb).

Making maize easier

Maize can be difficult to grow. Every farm’s situation is different, so seek guidance from your advisor. To help you, we have compiled some pointers with the Maize Growers’ Association. Don’t forget, though: maize is a poor competitor for soil nutrients at early growth stages, so remove problem weeds early.

Dry matter

For forage maize, try to achieve 30-35% dry matter: this should lead to the same percentage of energy-rich starch. For biogas maize, try to achieve 27-31% dry matter to enable effective fermentation.

Adjust dry matter as plants grow by managing seed rates, drilling dates, nitrogen levels, choice of variety and use of starter fertilisers.

Seedbeds

Soil structure and seedbed preparation are vital: to ensure rapid rooting, deep-cultivate or plough the field, especially if it has been trafficked through slurry or FYM applications.

The seedbed should be fine enough for good germination but not so fine that capping may occur.

Drilling

Only drill maize when soil temperature is over 8°C at 9 a.m. for seven consecutive days.

To grow quickly and efficiently, maize requires warm days and nights. If you are growing under colder conditions, choose varieties from earlier ‘maturity groups’.

Good germination and early vigour are essential to avoid gappy crops and achieve best yields.

Pests

Where you have soil pests such as wireworm, treat maize seed with Sonido.

Harvesting

Later harvesting can produce higher yields but at the risk of soil compaction and run-off with potentially serious environmental effects.
