How does Elaeagnus angustifolia prevent insects

Elaeagnus angustifolia can prevent pests by chemical control and pruning diseased branches. The mixture of dichlorvos and dimethoate EC can be sprayed on the positive and negative sides of the leaves to eliminate and prevent the jujube Psylla. Another way of pruning diseased plants is mainly suitable for the emergence of diseases and insect pests or when diseases and insect pests are flooding in a large area. Cutting off the diseased plants in time also has a good preventive effect. 1、 How to prevent pests of Elaeagnus angustifolia 1. Chemical control: during the growth period of Elaeagnus angustifolia, the more likely pest is Elaeagnus angustifolia wood lice. The way to control this pest is very simple. There are two ways. The first is to use 80% dichlorvos stock solution and 50% dimethoate EC, mixed with water, diluted and sprayed routinely. Second, mix dichlorvos and dimethoate stock solution with binary oil in the ratio of 1:2:1, and then spray it on the leaf surface. Both pesticides can be sprayed in a conventional way. If conditions permit, they can be sprayed in a low amount by aircraft, and the effect is better.

2. Pruning diseased plants: when the insect damage is serious, the diseased plants with insect damage can be directly cut off, and they can be separated from healthy branches to isolate pathogens. Appropriate pruning and closed cutting can also be used to enhance the disease resistance of Elaeagnus angustifolia and reduce the incidence of pests. 2、 How to sow and raise seedlings of Elaeagnus angustifolia 1. Seed seedling raising can be used to plant Elaeagnus angustifolia. Select the seeds with full particles and no pests and soak them in warm water for 2-3 days, which can make the seeds absorb water and expand.

2. Mix the seeds with 40% methyltobuzin wettable powder, stir evenly, and then moisturize and promote germination. When a large area of seeds is exposed, they can be sown.

3. Select plots suitable for planting and apply base fertilizer before planting. When planting, dig a deep ditch of 3-5cm, put the seeds in, cover the soil and water. (ShaZaoZenMeFangChong)
