the tomato/potato psyllid is an introduced pest that can run havoc in your garden as you are experiencing. Their life cycle is complex and treatment can be effective with a varied approach. In the first identify the deposits, eggs and leaf infection to gauge if any other plants need treating as well. Identifying eggs ? these are yellow in colour and oval in shape that is attached to the leaf with a stem. Things to look for on leaves – their excretions which are called ?psyllid sugar? are easily seen and is the most common symptom gardeners see on their plants. Discoloured leaf edges upturn and shop yellowing or purpling. Check other plants for these symptoms as your food plants they are most likely to be interested in are capsicum, egg plant, potatoes, tomatoes and will even spread to kumera. Remove and destroy affected leaves by method of containing in a sealed bag (either tie off a rubbish bag or pop in a sealed container) for 4 ? 5 weeks then destroy. Hang yellow sticky traps from the top of your plants to catch adults and an insecticide that controls aphids will work. Pop into your local store where you can get the sticky traps and insecticide. Best of luck!
