Brassicas is the name given to a family of plants that includes popular vegies like cabbage, kale, broccoli, cauliflower and Brussels sprouts. Winter is ideal for growing these delicious and super healthy vegies, whether it’s out in the vegie patch or in pots on a sunny balcony, veranda or patio.
These vegies are unfortunately also very popular with caterpillars, including the voracious cabbage white butterfly and cabbage moth caterpillars as well as lopper caterpillars. They can rapidly skeletonise leaves and chew into and ruin heads of cabbage, cauliflower and broccoli.
You may not see the caterpillars themselves, just the damage they cause or their droppings. To ensure you’re able to eat more of your brassicas than the caterpillars, you can protect your precious plants with Yates® Nature’s Way® Caterpillar Killer. Also known as Dipel®, it’s based on naturally occurring beneficial bacteria that only affects caterpillars. It’s safe for beneficial insects like bees and ladybirds and is certified for use in organic gardens by Australian Certified Organic.
Spray foliage every 5 – 7 days, including the undersides of foliage where caterpillars often hide. The spray does not kill the caterpillars immediately. After a caterpillar eats the sprayed foliage, it stops eating but may take up to 3 – 4 days to die and drop from the leaf.
