Comet 200 is a fungicide with protectant and curative properties for disease control in winter wheat, spring wheat, winter barley, spring barley, winter oats and spring oats. Comet 200 is also a fungicide with protectant properties for disease control in forage maize and grain maize.
- Yield response even in the absence of disease
- Delivers additional yield, quality and disease control when used with SDHIs (such as Adexar) and triazoles.
- Best rust strobilurin with good activity on abiotic spotting, rhyncho, net blotch and Septoria in wheat and barley
- Improved drought/cold/heat tolerance protects yield in stress situations
- Reduces plant stress by reducing/reversing ethylene production caused by leaf damage

Why Comet® 200?
Comet® 200 can prevent yield loss by direct control of diseases, for example rusts and net blotch but in addition may bring extra yield even in the absence of disease. Comet® 200 improves nitrogen assimilation by increasing nitrate reductase activity and has been shown to give a more consistent response over varying nitrogen levels (ADAS). Comet® 200 has also been shown to increase light use efficiency - lower light reflection from the crop means more light is used by it for photosynthesis and yield generation (ADAS Boxworth).
In maize, an increase in cob weight of over 30% has been demonstrated and increases in dry matter and feeding units per hectare worth an extra €274/ha (BASF Denmark 2012).
Production efficiency and quality
In silage maize*, Comet® 200 not only increases yield, but also quality and feed intake. As well as an increase in cob weight - over 30% heavier cobs in maize -, a more even cut of better quality has been demonstrated that has led to a more dense clamp and higher intake by cows.
Stress and drought tolerance
Comet® 200 is the only strobilurin to have a label claim for increase in yield in the absence of disease. Comet® 200 is also the best 'stress-busting' strobilurin. It helps keep crops cooler in hot conditions and reduces the levels of stress hormones (ethylene) and damaging free radical molecules in the leaves.
Comet® 200 is the only strob to have demonstrated reduction of germ tube growth of strob resistant Septoria, leading to improved control when used early in the programme. It has an alternative mode of action against rust and reduces the selection pressure on triazoles early in the season against Septoria when used in combination with a protectant.
Even in a “low” disease season where no rust is present, Comet® 200 shows a significant increase in Septoria control and an improvement in green leaf area
