Deal early to garden pests
Potatoes planted within the last couple of months will need to be protected from the psyllids.
Citrus trees should also be treated the same way to prevent insect pests from establishing.
Aphids on roses and other plants can be controlled with a combination spray of Key Pyrethrum and Wally’s Neem Tree Oil. Mix with warm water, and spray just before dusk to take care of leaf hoppers, mealy bugs, beetles, caterpillars, psyllids, and whitefly.
Spray black pear/cherry slugs on your plum, cherry or pear trees with Wally’s Liquid Copper. If you don’t control the first flush, a second generation will appear about February and do far more leaf damage.
If you find holes in the leaves of plants but no culprits, it’s likely to be either grass grub beetles or birds. Check with a torch after sunset for beetles and spray them with Key Pyrethrum, which only has a one-day withholding period on food crops.
Porina caterpillars in the lawn are easily controlled with Wally’s Neem Tree Oil mixed at 15ml per litre of warm water. Cut the lawn and just before sunset, spray the base of the grass where the caterpillars feed.
Yellow sticky whitefly traps are starting to catch whitefly and psyllid adults now that the weather is warming and settling.
