What have we observed about addressing the pompom threat?


Herbicide –
•    Can be obtained from www.ecoguard.co.za
•    Recommend Plenum
•    Plenum requires a wetting agent (called Actipron) and a dye (blue is best)
•    The Actipron and dye should be mixed with the herbicide on the day of use and should be used on the same day (efficacy deteriorates once mixed)
•    Plenum comes in 10 liter container only (and you will spend around R3500 to get started when you buy from Ecoguard in the minimum quantities)
Use of herbicide –
•    Toxic, and must be used with great care and wearing protective gear
•    May not be used in water courses, near boreholes, in wetlands
•    Should not applied in windy conditions
•    Is not effective when temperature exceeds 290C because of the plant’s protective mechanisms
•    Must rest on the plant for at least 2 hours to take effect
Best results achieved when –
•    Work commences early summer when the plant is very small
•    Work is followed up at least once, but preferably three to five times during the season
•    When herbicide is applied BEFORE a flowerhead forms
Flowers –
•    It is an insufficient and wasteful effort to cut off the flowers
•    A cut flower stem on a growing plant WILL produce between 5 and 7 NEW buds
•    If the flower has opened (is fluffy) when the herbicide is applied, it is better to cut the flower off
Later
Many land users delay treating the plants because they are waiting for the neighbours, the roads department, a change in circumstances, etc.  Delaying the treatment will make the situation worse.  The plants do not disappear – they are dormant in winter and flourish in the spring.  The seeds are very effective, and a few WILL be many next season.  Fire does not destroy the plant. Cutting it down stimulates growth.
