1. Himalayan Blackberry Background • Most common blackberry • Came natively from Eurasia • Known to take over stream channels and ditch banks, killing other species. • Grows quick, spreads through roots and seeds. • Almost impossible to eliminate

2. Blackberry Control • In order to eliminate blackberries permanently you can use several methods, most effective if you use them repeatedly. • Whether it be from Herbicides or hard labor you will see the best results if you combine both together. • Herbicides should always be your last resort as they can damage the eco-system even further • More detail for both methods is available in further slides but I don’t feel the need to get into it

3. Blackberry Control Hand and Mechanical “Blackberry canes (stems) grow from underground burl-like root crowns. Where berry plants are few in number, they can be killed by grubbing out the burls with a mattock. Larger infestations away from fences or ditch banks can be disked out with repeated cultivations if the soil is not too wet. It may be necessary to burn out large thickets where appropriate before disking. Hand grubbing will be more effective after disking when new canes are forming. Blackberry vines are vigorous Re-sprouters if the burls are not killed. Patience is required for successful control.” Source: http://ceamador.ucdavis.edu/files/957.pdf

4. Blackberry Control Control with herbicides “Glyphosate (Accord, Roundup, Rodeo) and triclopyr (Redeem, Remedy) effectively control blackberries. Application timing (growth stage) and season are important in using these foliage-applied translocated chemicals. Repeat applications if necessary to completely remove the plants.” Source: http://ceamador.ucdavis.edu/files/957.pdf
