The safest and most effective method for ridding food crops of cabbage looper and other lepidopterans (moths and butterflies) is BT. This is a beneficial bacteria that kill the larvae when it feeds on the treated plant. BT stands for Bacillis Thurengensis. Safer brand "Caterpillar Killer" is the most popular edition of this for the non-professional. It's easy, you just spray it on the leaves. Find it at any garden center or Home Depot. It will work instantly, and you won't enjoy a problem. It is a great preventive treatment as well. dust the plant with cyan pepper powder
Answers: Grubs of the cabbage moth or white cabbage butterfly are a common pest on various home veggies. These green caterpillars grow to around 30-mm long (1") and can cause masses of trash to plants or fruit. Being vigilant is the first step, watch out for leaf or fruit disrupt, generally first seen as small holes, or the tell-tale white butterflies as they flit around looking to deposit eggs. It's later you need to consider treatment or control.
Younger plants will be most damaged, within fact many elder plants may only suffer cosmetic damage to leaves that you may prefer to tolerate for the sake of a truly organic crop.
In the first instance, particularly if your crop is small, you may be capable of physically remove and dispose of all of the grubs. Look on the underside of leaves as the green caterpillars tend to hide near during the day to avoid being eat by birds.
If there comes a need to spray to knock-off the pests afterwards the first step is to ensure that what you use is appropriate for food crops & to observe all of the safekeeping precautions including withholding period (the time that must elapse between spraying and harvesting).
Many people find they hold success with home brew formulas containing things similar to chili & garlic or, if you can see each grub, you may find a pyrethrum spray will do the trick.
If you need to resort to using a commercially available product afterwards seek out those that are based on caterpillar specific germs. Yates (www.yates.com.au) make a couple of these for example.
Ask your local garden professional for advice on the best product for your desires, its a good idea to bring a sample of the damaged fern or fruit with you (or even a grub in a jar!). Make sure that you explain that the product will be used on tasty crops and before you leave the store read adjectives of the instructions first to ensure suitability with your needs. Don't clutch the old pack of a product like tomato or cabbage dust thats be sitting at the back of the garden shed for 5 years. It may well contain immediately banned or de-registered active constituents such as Carbaryl.
A preventative step that can be taken, extremely if you prefer to keep things sustainable & organic, is to explore the reach of companion plants that you can put in when you plant your seedlings.
Plants such as marigolds, garlic & onions (some right to be heard garlic chives too), nasturtiums, sage or mint are just a few. Just google 'companion planting, vegetables' to find a list for your requests and region. You'll find they don't just help next to pests they'll give you a beautiful and suspended veggie patch.
Happy gardening!
