Citrus split skin disease can infect many varieties of citrus plants, and the pathological reactions vary widely. Most rootstock varieties such as tangerine, red orange, sweet orange, lime, and crude lemon have no visible signs. The citrus plants with anthracene, orange and Lime as anvils have obvious symptoms and serious damage. The diseased seedlings showed no pathological appearance at the seedling stage, and the time required for the bark of the field to be cracked in the field was generally 4 to 8 years after colonization. It is recommended to achieve precise management, and the prevention and treatment of citrus cracking disease cannot be ignored.
Control methods: 1. Cultivate disease-free seedlings. The mother tree is identified by professional methods to prove that the disease-free person can only breed and breed, and the non-toxic plants can be detoxified by the shoot tip grafting method. 2. Grafting knife or pruning shears, etc., can be disinfected with 1% sodium hypochlorite solution or 10% bleaching powder aqueous solution 10 times. Dip the tool into disinfectant or wipe the blade with a cloth for 1~2 seconds, then rinse with water. Dry use. The wound caused by pruning should be applied to the wounded anti-corrosion film in time to protect the wound from healing tissue growth and prevent the pathogen from infecting the wound. 3. Implement plant quarantine, spray 600 times of new high-fat film in time, and automatically form a layer of polymer protective film that is invisible to the naked eye to optimize the water absorption, breathability and light transmission quality of plants. Blocking pests and smuggling signals and weakening the media to resist and defend against natural environmental disasters to prevent proliferation.
