The Hazera onion disease app is a practical instrument for onion growers to recognise diseases and malfunctions in onion. It features detailed explanations, pictures and recommendations on bacterial, soil-borne, virus, foliar and storage diseases, insects, nematodes and disorders. It also offers company information and contact persons.
This app would be awesome if the picture would load. I have the tomato app and it asked to download 200 plus pictures. This one should do the same but it hasn't prompted for it.
