![]() For in-depth species profiles, scroll down to the problem and common weeds of field crops below, and click on the images to reach the species page. Then the model will be embedded in an app for people to use on their phones,” he said. They have photos, identification tips, and chemical, mechanical, and cultural management options for the most common and troublesome field crop weeds. ![]() “The next step is using AI to train a weed image classification model so the AI can accurately recognise each weed species. We try to find weeds growing at different life stages, such as before it flowers and after it sets seed. Then we take photos of the weed from multiple different angles. “Firstly, we identify each weed plant carefully. “We are working on 300 priority weed species that are causing problems in different places all over Australia,” Alexander said. The latest app is WeedScan, a collaboration with NSW Department of Primary Industries (DPI) and the Centre for Invasive Species Solutions, funded by National Landcare.Īlexander is coordinating field work from Tasmania to the Top End to take photos of weeds growing in bushland and on farms. He now uses artificial intelligence (AI) to build apps to identify invasive insects and weeds. In recent years, Alexander has expanded his work as a taxonomist classifying daisies. To identify a pest plant, enter the name of the plant. Many daisies, such as dandelions, are successful weeds because their seeds can travel long distances on the wind. Our pest search has photos and descriptions of all pests in Auckland. There are more than 25,000 species in this family. Identifying weedsĬSIRO botanist Alexander Schmidt Lebuhn specialises in daisies. Enter the idea for a national scale weed identification and reporting app. Identifying and reporting harmful weeds is important for managing both farmed and natural landscapes. They make up about 12 per cent of our flora, a higher proportion than any other continent. ![]() Weeds cost Australia’s agriculture industry at least $5 billion a year. Blackberries are delicious but one of Australia’s worst weeds.
