Purple Moss Diseases and Pests and Their Control
As a common ornamental plant in courtyards, Purple Moss is deeply loved for its brilliant flower colors. However, many plant enthusiasts have noticed abnormal phenomena such as yellowing and curling leaves on the plants, which often herald the invasion of diseases and pests. This article will systematically analyze the common diseases and pests of Purple Moss and provide scientific control methods.
Purple Moss Disease Control System
Foliar Blight: Typical Symptoms of Fungal Infection
In the North China region, July is the peak period of high incidence, with brown circular spots appearing on the leaves and gradually expanding. A three-step prevention and control method is adopted: ① promptly remove and destroy the diseased leaves; ② alternately spray 800 times the solution of chlorothalonil and 1000 times the solution of carbendazim, with an interval of 7 days; ③ apply additional phosphorus and potassium fertilizers to enhance disease resistance and maintain soil permeability.
Strategies for Dealing with Purple Moss Pests
Leaf Pest Control
Leaf-rolling caterpillars weave silk to damage leaves, and fenvalerate emulsion can be used for targeted spraying. Snails hide during the day and eat tender leaves at night; after rain, apply aldicarb granules around the plants to form a protective circle.
Control of Subterranean Pests
Grubs eating the roots cause the plants to wilt; it is recommended to use phoxim granules for soil disinfection before planting, and set up black light traps during the adult stage for physical control.
Fruit Pest Management
Peach borers bore into seedpods. Spraying 3000 times the solution of fenoxycarb emulsion in advance during the bud formation stage can prevent it, and any fruit with signs of borer damage should be promptly removed.
By establishing a plant protection system that focuses on prevention and comprehensive management, the resistance of Purple Moss can be significantly improved. It is recommended to clean the leaves monthly and regularly rotate the use of different mechanism-based pesticides. Combined with reasonable pruning to improve ventilation and lighting conditions, the incidence of diseases and pests can be reduced by more than 60%, allowing Purple Moss to continue to bloom with healthy beauty.
