The power of Mycotal + Addit
19 August 2009
In the Netherlands, Mycotal + Addit has been used more than 15 years. Target pests are whitefly, thrips and it has a side effect against spider mite. So far no resistance has been seen, and none is expected. This is a big difference from many chemicals. Another big advantage: Mycotal+Addit has no MRL!
Recent trials in Spain and Holland confirmed the excellent results on whitefly: 88% mortality on whitefly larvae in cucumber, one week after a single treatment.
In the UK, last year a trial with Mycotal (without Addit) in Poinsettia was carried out by the Central Science Laboratory in York. The effect on Bemisia eggs was 60% reduction. On the second instar larvae the reduction was around 70%. In this trial , the chemical product Oberon was a reference and gave on the eggs a reduction of 10% and on the second instar larvae 68%. The combination Mycotal + Oberon gave on the second instar larvae an effect of 85%. This study shows the good effect of Mycotal but shows also that a tank mix of Mycotal with Oberon increased the effectiveness of both products.

Some tips for use
- Mycotal + Addit is most effective on white fly larvae (stage 1 - 3) and thrips larvae (stage 1 and 2).
- Use Mycotal + Addit in an IPM system before whitefly or thrips population is too high. Start in time with corrective measures.
- Spray 3 times with an interval of 5-7 days to cover one generation of the pest.
- Use Mycotal + Addit in rotation with insecticides in a chemical (non IPM) system
- Against thrips: best results will be obtained in crops were the relative humidity is higher like cucumber, beans and chrysanthemums.
- Mycotal + Addit is a contact product. Use the right spraying equipment.
- Combinations with insecticides against whitefly and thrips is possible (for example Mycotal + Addit + pyriproxifen). This results in a ‘1 + 1 = 3’ effect.
