Methods of beech pest control

1.When the beech tree appears big bag moth to eat the leaves, you need to use 90% trichlorfon dilution 1200 times of the solution, or with 6 diluted 000 times of the solution of the beech to kill 1 2 times every 2 months to control the bag moth, to avoid the yellowing of the leaves of the plant, wilting, the big bag moth generally appears on the back of the leaves, spraying pesticides must be sprayed on the back of the plant.

2.When there are borers on the zelkova tree to suck nutrients, it is necessary to dilute the solution of 1000 1500 times with 50% malathion emulsion, or the solution of deltamethrin emulsifiable concentrate diluted 3000 times to spray the zelkova tree to avoid malnutrition and defoliation when the plant grows.

3.When poisonous moths appear on beech trees, it is necessary to spray the plants with a solution of 1000 1500 times diluted with 40% acemethamidophos emulsifiable concentrate and a solution diluted 1000 times with 50% pine borer to prevent the poisonous moth from burrowing into the cracks of the bark of the plant, eating the trunk and roots, resulting in the failure of the plant to grow normally, or even death.

4.When there is a small ground tiger on the beech tree, it can be controlled by manual hunting. Soak a towel in a solution diluted 1000 times with 50% dichlorvos, soak for 10 minutes, take it out, and wipe off the trunk where there are small ground tigers and wipe them off with a damp towel.

Pest control. There are not many beech tree diseases and insect pests, and the common ones are big bag moths that eat leaves, and the damage is the most serious from July to September, and can be sprayed with 90% trichlorfon solution. It can also be manually cut in winter or early spring.

Beech. It is a common ornamental plant with high appreciation value and is sought after by the majority of plant lovers. The growth of beech is relatively slow and needs more careful maintenance, so let's introduce the maintenance skills of beech.

First of all, when planting beech, you can use fertile and well-drained soil, and prepare an appropriate amount of decomposed compost or compound fertilizer for it to ensure that it has sufficient nutrients**.

Secondly, in the process of maintenance, it is necessary to pay attention to the watering of the beech, generally speaking, the appropriate amount of watering per week is enough, but it is also necessary to adjust it according to the weather conditions. When it is dry in summer, you can increase the amount of watering appropriately, but not too much, so as not to cause root rot.

Beech needs the right amount of light to grow, so we need to choose a location with plenty of ambient light for planting. When planting indoors, it is necessary to clear windows or other obstacles in time to ensure sufficient light.

In addition, we need to prune the zelkova regularly to promote its flourishing. It is possible to cut off the withered or overgrown parts to maintain the overall appearance.

In short, the maintenance of zelkova requires our patience and care, and only with adequate preparation can we harvest a healthy and beautiful plant.

Beech tree breeding should control the temperature between 15 and 25, ensure that the scattered light is sufficient, choose fertile and loose soil, water every 5 days in spring and autumn, water every 5 days, water every day in summer, water once a month in winter, apply basic fertilizer in the early stage of growth, and apply nitrogen, phosphorus and potassium fertilizer in the later stage.

When cultivating zelkova trees, the temperature needs to be controlled between 15 and 25, and the plants need to be guaranteed to have 5 7 hours of scattered light time every day, and they must do a good job of shading and sun protection in summer. The soil for cultivating zelkova trees needs to choose soil containing sand, peat, vermiculite, and humus.

In spring and autumn, water every 5 days, watering the roots of the plants until the water can penetrate the bottom of the soil. In summer, the beech tree is watered once a day, and the beech tree is wrapped from the root to the tip with a straw rope to lock in water and moisturize. In winter, just water every other month.

In the early stage of zelkova growth, a small amount of farm fertilizer and organic fertilizer should be applied quietly, and in the growing period, it is necessary to apply 1 or 2 times every other week, fermented nitrogen and phosphorus fertilizer or oil meal water, and in the later stage of growth, phosphorus, potassium fertilizer, and potassium dihydrogen phosphate or superphosphate of the witherer.

Prune the branches and leaves of zelkova trees in spring and during the dormant period, prune off the branches in the spring where the growth is messy or densely grown, and prune off the dead, thin and diseased branches on the plant during the dormant period. Every 1 2 months, the zelkova can be loosened and weeded 1 2 times, the soil can be loosened to improve ventilation and drainage, and the weeds around the roots of the plant can be removed regularly, which can reduce the loss of plant nutrients.

Beech trees have serious diseases, and more than 20 kinds of insect pests have been found. The main pests at the seedling stage are small ground tigers, aphids, inchworms, leaf borers, poisonous moths, bag moths, beetles and other hazards, which can be sprayed with 80% dichlorvos 1000 times liquid, 90% trichlorfon 1200 times liquid or 6000 times liquid and other insecticides 1 2 times per month. Small-ground tigers must be watered or killed with poisonous bait.

After afforestation, it is necessary to control the main dry-boring pests such as purple stem beetle, a little flat moth, and codling moth. It should be combined with tending, germination, pruning and other work, check the harmful parts, and kill them with iron wire in a timely manner, or use absorbent cotton dipped in insecticide stock solution or low-power dilution solution such as methamidophos, dimethoate, dichlorvos, etc. to block the insect holes to kill. The fundamental method of control of purple stem beetle is to remove kudzu vines in the forest.

For leaf-eating pests, it can also be considered to trap with black light or sweet and sour liquid with insecticides.
