I plan to plant gastrodia next year, but what pests harm gastrodia? What methods can be used to control them? I hope experienced netizens can offer guidanceThe pests that generally need to be controlled when planting gastrodia mainly include white grubs, springtails, mole crickets, scale insects, and termites. The following is a detailed explanation (if you have better methods, you can post them at the bottom. Many thanks from Zhongdiwang).
1. Control methods for white grubs and mole crickets, pests of gastrodia:Per 100 sq m, use 0.15 kg of 90% trichlorfon crystal or 50% phoxim diluted with a small amount of water, mix with 10~15 kg of fine soil to make poisoned soil, and broadcast it.
2. Control method for springtails, pests of gastrodia:Springtails are small in size and white in color. Higher humidity favors their occurrence, and they are most active at 20°C~25°C. They can reproduce 6~7 generations a year. They mainly bite and feed on the mycelial membrane inside the cortex of the fungus sticks, and also feed on gastrodia stems and tubers, causing rotten holes in the gastrodia tubers. During the peak occurrence period, spray or drench with an 800~1000 times dilution of dichlorvos solution or 0.1% derris extract solution, or fumigate with 4 tablets of aluminum phosphide per sq m.
3. Control method for termites, pests of gastrodia:In addition to harming the fungus wood, termites also bore into and feed on gastrodia protocorms and tubers. During the peak damage period, termite powder can be used to poison and kill them.
4. Control method for scale insects, pests of gastrodia:The main problem is mealybugs harming gastrodia tubers. They are generally brought into the pit by trees such as fungus wood and new wood. After the damage, the growth of gastrodia weakens and the quality decreases. If damage occurs, the gastrodia in that pit should be dug up promptly, all processed into commercial gastrodia for sale, and strictly forbidden to be kept for seed. The fungus wood in that pit should also be burned to prevent spread.
