Groundbreaking Biological Control Trial to Combat Bronze Beetle
At Bostock NZ, we’re committed to driving innovation in organic horticulture — finding smarter, more sustainable ways to protect our orchards and improve fruit quality. One of the biggest challenges we face is the bronze beetle, a destructive pest that can damage up to 25% of organic apple crops, costing growers up to $13,000/ha annually in damaged fruit and physical control methods.
To tackle this issue, we’ve launched a cutting-edge biological control trial aimed at reducing bronze beetle damage in our apple orchards. By injecting beneficial nematodes directly into the soil, these microscopic organisms naturally prey on soil-dwelling pests like bronze beetle larvae at the root zone. Offering a revolutionary alternative to traditional organic pest management practices, such as intensive under-tree cultivation.
Using high-pressure air-injection technology, the nematodes are delivered directly into the soil using compressed air, targeting bronze beetle larvae before they emerge. This method not only aims to reduce pest pressure but also supports soil health and improves fruit quality both pre- and post-harvest.
We’re working with Air8tors Ltd, led by Clive Umbers, who brings over 20 years of experience in air soil aeration and biological soil enhancement. Their technology enables precise delivery of biological inputs directly to the root zone, helping us explore new ways to manage pests naturally.
This innovative technique is a bold move toward cleaner, smarter growing — and we’re excited to see how it transforms orchard health and fruit quality.
