Product Details
Red leaf Photinia is a general term for the hybrid species of Photinia in the Rosaceae family, named after its bright red shoots and tender leaves. It has many cultivated varieties, including leaf spot disease, gray mold disease, and other common diseases. Common pests include aphids, crustaceans, and longicorn beetles. Let's take a look at the common pest and disease techniques of Red leaf Photinia together!
Gray mold disease
【 Harmful characteristics 】 Gray mold mainly damages the tender branches, young stems, leaves, flowers, and fruits of red leaf photinia. The disease spots initially appear as small water stains, then expand into large gray spots with irregular round shapes. Finally, the infected area is covered with gray mold layers until necrosis or decay.
【 Method 】 Strengthen cultivation management in daily life, pay attention to removing accumulated water, reducing humidity, and removing diseased and residual bodies. Before the rainy season, 50% carbendazim 800 times solution spray can be used for prevention, and 50% mancozeb 800 times solution or tobuzin 800 times solution spray can be used during the onset period.
Leaf spot disease
【 Harmful characteristics 】 Leaf spot disease mainly damages its leaves and stems. When the leaves are affected, brown spots first appear, and then gradually expand and develop into multi angular disease spots. The disease spots on the front of the leaves are reddish brown, and on the back are yellow brown. When the disease is severe, the disease spots can form blocks, or even the entire plant withers.
【 Method 】 In winter and spring seasons, combined with nurturing management, concentrated cleaning of fallen leaves and elimination of overwintering pathogens. Spray 1% equivalent Bordeaux solution every 10-15 days in March and early June for prevention, and use 50% carbendazim 300-400 times solution or 50% tobuzin 300-400 times solution during illness.
illness
【 Harmful characteristics 】 Disease is a major disease that occurs during the cutting period of red leaf photinia. It is more likely to occur under high temperature, humidity, and poor ventilation environmental conditions, which can easily lead to the condition of red leaf photinia only taking root but not sprouting.
【 Method 】 After the completion of seedling cutting, it is necessary to pay attention to the humidity and temperature of the cutting bed at all times, maintain good ventilation, and pay attention to removing severely affected diseased leaves. At the initial stage of the disease, use 500~1000 times liquid of 70% tobuzin wettable powder or 600 times liquid of 65% mancozeb wettable powder to spray, and spray again every 7~10 days.
aphid
【 Harmful characteristics 】 Aphids, also known as putty or honey insects, are adult aphids or if aphids cluster on the young buds, tender stems, or tender leaves of red leaf photinia. They use needle shaped suction mouthpieces to suck on the sap of the plant, causing the leaves to curl and shrink towards the back, directly affecting the growth and ornamental value of red leaf photinia. They can also cause coal pollution disease, have a large breeding volume, and are prone to disasters in dry seasons.
[Methods] Generally, when the temperature rises in spring, 10% omethoate emulsion 1000 times or malathion emulsion 1000~1500 times or dichlorvos emulsifiable concentrate 1000 times is sprayed. During the high incidence season of aphids from March to October, aphid repellent or aphid repellent are sprayed every 7 days to prevent adult infestation.
Crustacean
【 Harmful characteristics 】 The shell insects mainly include the white wheel shield scale, which damages the top buds and tender branches of the red leaf heather. When severe, they can cover the entire branches and leaves, leading to coal pollution disease and affecting the ornamental value.
【 Method 】 Before sprouting in spring, spray 10% to 15% diesel emulsion for prevention. When the disease occurs, spray 40% omethoate 1000 times solution, or 2.5% deltamethrin 2500 times solution, 20% chrysanthemum oil 2500 times solution, and 40% rapid killing oil 1500 times solution, all of which can achieve good results.
Longicorn beetle
【 Harmful characteristics 】 The longicorn beetle mainly drills and damages the branches and trunks of red leaf photinia during its larval stage, which lasts for a long time and affects the growth and development of the plant. It weakens the tree, leading to the invasion of pathogens and being easily broken by wind. When severely damaged, the entire plant dies, seriously affecting its ornamental value.
【 Method 】 The main method for treating longicorn beetles is to use a combination of measures such as applying white paint on the tree trunk to avoid laying eggs of adults, manually killing eggs, larvae, and adults, and injecting medication into the tree trunk wormholes. The medication can be 50% malathion emulsifiable concentrate, 50% dichlorvos emulsifiable concentrate, 40% omethoate emulsifiable concentrate, and 2.5% deltamethrin emulsifiable concentrate 200 times.
