(Botrytis paeoniae) Peony wilt is a common fungal disease of peonies, producing brown patches on the leaves and stems, which then collapse, and flower buds fail to develop and open.

(Taphrina deformans) Peach leaf curl is a fungal disease that attacks peaches and nectarines and sometimes almonds and apricots. It produces distorted leaves with red blisters.

(Sclerotium cepivorum) Onion white rot is a devastating fungal disease of onions, leeks and garlic and other plants in the allium family. It causes the plants to rot, making them unusable.

(Gaeumannomyces graminis, Laetisaria fuciformis, Monographella nivalis and other species) Lawn grasses are subject to a number of disease problems. Luckily, they rarely do very severe damage, but can lead to brown patches and areas of dead grass.

(Armillaria species) Honey fungus is a devastating disease of trees, shrubs and other woody, and some herbaceous, plants. It attacks and kills the roots, then rots the dead wood.

(Numerous fungal species – including Cercospora, Microsphaeropsis and Septoria) Fungal leaf spot diseases attack a very wide range of plants, producing spotting or marks, in numerous different shapes, sizes and colours, on the leaves.

(several fungus-like organisms) Downy mildew diseases attack many ornamental and edible plants, producing a range of different symptoms, including discoloured, shrivelled and brown leaves.

(Fusarium, Phytophthora, Pythium, Rhizoctonia) Damping off is a disease that affects seedlings, causing them to collapse, keel over and die. They may also become covered in a whitish, furry fungal growth.

(Numerous species) Annual weeds are easy to deal with, especially if controlled as seedlings or young plants. Then, they don’t get out of control and become a time-consuming problem.

(Mercurialis annua) Annual mercury is a common weed throughout the garden, but particularly wherever soil is disturbed or cultivated. It sets lots of seeds each year and spreads readily.
