Exclusion bags - the verdict



Our ongoing battle with fruit fly is familiar to long-time readers of this blog. Even though we didn't know it at the time, our decision to plant stone fruit set us on the path of a long and frustrating battle with these pesky buggers, usually ending in victory for the fruit fly. It was a case of to the defeated the spoils, as we bagged up kilos and kilos of spoilt peaches, plums and feijoa over the years.

This year, we decided to conduct a controlled experiment with the use of exclusion bags. These are little paper bags with a wire insert that allows you to cover up each fruit totally closed, keeping the little buggers out. Not much hope though. Fruit fly are insidious little things.

We bought 6 packets of 25 bags at the cost of about $35 dollars, and used them on our plums, white peach and nectarine. We had fantastic fruit set this year, so we knocked off heaps of small fruit and kept the rest of the fruit uncovered with the intent of spraying with Eco-naturalure.

Unfortunately, our plan to spray was totally nixed by a very wet spring - we barely had two days running of dry weather for a couple of months. So in the end, the uncovered fruit wasn't treated at all.

The result - hooray, the exclusion bags worked! For the first time, we are eating our own unspoilt white peaches. And yes, the uncovered fruit has been spoilt. Unsurprisingly.

If you're interested, you can purchase exclusion bags on line here at the Green Harvest website.

Actually, this is an interesting little website offering all sorts of organic gardening supplies.
