1. Vaccinated plants often suffer from large areas of bark rot, preventing nutrient transport, resulting in branches and leaves falling, in serious cases the death of the whole plant. Fluidic lesions often occur in the trunk. The damaged bark was water-stained, turning brown and often leaking glue. When dry, the cortex is cracked and the xylem is exposed. The pathogen is a variety of fungi. Factors that can cause excessive humidity in the orchard: such as soil viscosity, poor drainage, excessive planting, intercropping high-stalk crops, can cause the disease to occur. Control methods: In the diseased section, a shallow and scratching method is adopted. First, the rough skin scraping of the diseased part (now going to green and yellow is appropriate) is followed by slitting several slits, reaching deep into the xylem, and then coated with 50% thiophanate or multiple bacteria. Spirit 100 to 200 times liquid. Disease-resistant rootstocks such as red tangerine, lime, etc. can also be used. Raising the grafting site can also reduce the occurrence of dermatosis. Pay attention to drainage and improve orchard environmental conditions.
2. The spider mites and yellow spiders mostly occurred in April-May and August-September. When the damage was most severe, all the leaves of the plants turned yellow, the tree vigor was weak, and even a large number of deciduous and deformed flowers increased. Team management methods: When lime sulfur is used to control fleas, the preparation concentration should be lower than that of citrus, especially in winter, so as to avoid phytotoxicity and defoliation.
