How to control the diseases and insect pests of hickory? Please guide the prevention and control methods of diseases and insect pests of Carya cathayensis can refer to the following: there are many diseases and insect pests in Carya cathayensis seedlings, the common pests are buds, beetle larvae, ground tiger larvae and so on, the disease is mainly root rot. The prevention and control of diseases and insect pests should grasp the principle of "prevention is more important than control". The occurrence of buds can be sprayed with 50% dimethoate emulsion 1000-2000 times. Beetle larvae (ground silkworm harm hickory seedling root), ground silkworm can be artificially killed when sowing and ploughing the land, or pesticide methyl 1605 (powder) can be used to spread in the sowing ditch to poison the larvae. Golden Electronics has a generation a year, the adult period is long, and there are certain group activities in the nursery, which can be hunted and killed manually. The ground tiger (endangering the root bark of seedlings) can be trapped and killed by stacking grass in the drainage ditch and caught artificially in the early morning. In addition to timely drainage, the root rot of Carya cathayensis can be prevented by spraying 0.5-1.0% Bordeaux solution once a week in sunny days when the seedlings grow higher than 20cm. The cultivation of hickory mu is a production with high input, high output and risk. In recent years, there are very few successful nursery seedlings in the same year. The above technical measures should be fully mastered and tightly fastened, all of which are indispensable, and it is particularly important to promote germination and apply sufficient base fertilizer before sowing. Through scientific cultivation and careful cultivation, the height of Carya cathayensis seedlings can reach more than 50cm in one year, the diameter of rhizosphere is 0.5~0.8cm, and the seedling yield is about 10 000 plants per mu.
