Prevention and treatment of diseases and insect pests in spring

In early spring, most pathogens are in a dormant state, but as temperatures gradually rise, they begin to become active. At this stage, many disease-causing organisms tend to reside on infected plants, old leaves, and fallen debris. It's crucial to promptly remove these diseased materials and either burn them centrally or bury them deeply to prevent the spread of germs and diseases effectively. Rose rust, black spot, and powdery mildew often overwinter on branches, leaves, and buds. Before the flower buds start to open, it's recommended to cut off the affected parts of the plants and apply a 2–4° Baumé solution of lime sulfur. This treatment can significantly reduce the risk of disease during the blooming season. During the bud sprouting period, it's important to closely inspect rose buds for any signs of swelling or deformation. These symptoms are often the first indicators of rust. If detected early, affected leaves should be removed before yellow spores appear, helping to control the disease at an early stage. Botrytis, also known as gray mold, can affect numerous types of flowers and trees. Once the infection starts, it typically forms a fuzzy gray layer on wounds, dead leaves, or damaged branches. In greenhouses, high humidity in early spring creates ideal conditions for the rapid spread of this fungus. To manage the issue, it's essential to lower indoor humidity, avoid overcrowding plants, and promptly remove any infected flowers or leaves to eliminate hiding spots for the mold. From February to March, although pests may not yet cause visible damage, they are entering their reproductive phase. For example, scale insects are actively reproducing, overwintering aphids are beginning to hatch and feed on new growth, and moths like codling moths, leaf miners, and spider mites are preparing to emerge from their winter shelters. During this time, it's important to carefully inspect the stems and leaves of plants for signs of scale insects. If found, they can be manually removed. Flower beds that have been heavily infested by caterpillars should be pruned, with damaged bark and eggs scraped off the branches. Weeding and tilling the soil can also help eliminate overwintering pests such as Pygmaeopsis, Hymenoptera, and various moth species hiding in weeds and topsoil. By late March, a variety of plant diseases begin to appear. New infections such as black spot, powdery mildew, rose rust, and rhododendron leaf blight start to develop. Additionally, rust-infested larvae move from cypress and juniper trees to Begonia esculenta between late March and early April. This period is critical for disease prevention and management. Gardeners must monitor their plants closely and take action early. However, it's important to note that food roses should not be sprayed from bud formation until flowering to avoid contamination. For potted plants and trees, watering should be done carefully—avoid pouring water directly onto the foliage. Instead, water should be applied directly to the soil in the pot. Make sure that leaves do not remain wet overnight, as this increases the risk of pathogen infection and damage to the plants.
