Parthenium weed is the major host of tobacco streak virus (TSV) in CQ. To minimise the risk of TSV in sunflower and other crops:

• Choose tolerant sunflower varieties (listed in the brochure below).

• Become familiar with the TSV lifecycle, including hosts and the thrips vector.

• Avoid planting near or downwind of known parthenium weed infestations.

• Control other host plants in the vicinity, if practical.

• Expect infection levels of 20 to 60 per cent in susceptible cultivars if environmental conditions are conducive to disease outbreaks.
