What medicine is used for the withered leaf tip of sweet-scented osmanthus

If you want sweet-scented osmanthus potted plants to maintain good growth and ornamental effect, the usual maintenance and management work should not be careless. But sometimes we find that we have done a good job in light, temperature, water and fertilizer, but potted sweet-scented osmanthus still has poor growth. The most prominent performance is the leaf tip of sweet-scented osmanthus trees appear dry phenomenon, and even have the trend of expanding the area, how is this going on?

In fact, although the above commonly used management and protection work has been done well enough, the phenomenon of leaf tip dryness may still occur. First of all, we rule out the above reasons for the improper use of maintenance methods, and the rest may also be a detail that we are most likely to ignore. That is, the plant is infected with leaf blight.

Of course, it is a special drug for the prevention and treatment of leaf withering, but before spraying the medicine, we need to stop spraying and replenishing water immediately, otherwise it will only aggravate the disease and let the leaf tip withering spread more rapidly. Then we can targeted through drug intervention to achieve the effect of prevention and control, so that the situation can be controlled. The following are common prevention and control methods:

1. First clean up the diseased branches and leaves, and be careful not to let them fall into the basin, otherwise they will continue to infect healthy branches and leaves. Then these germ-carrying branches and leaves are burned together to remove the aftermath.

2. the next thing to do well is the maintenance and management of the disease period, so as to reduce or avoid the continued occurrence of the disease. In order to ensure fertility, looseness and acidity, the acidity of the soil was properly adjusted after loosening the soil to improve the soil quality to meet the growth needs of sweet-scented osmanthus trees.

3. Some organic fertilizer and a small amount of phosphorus and potassium fertilizer were mixed into the basin soil as base fertilizer to increase nutrients and plant immunity. Because sweet-scented osmanthus is not tolerant of big fertilizer, thick fertilizer, especially raw fertilizer. Therefore, it is recommended to use thin and rotten organic fertilizer, the concentration of phosphorus and potassium fertilizer should be low enough to avoid fertilizer damage.

4. Prune branches and leaves properly, especially those that grow too densely, in order to improve the effect of ventilation and light transmission. At the same time, pay attention to control the temperature and humidity, avoid putting it in a hot and humid closed environment, in order to reduce the risk of infection of diseases and insect pests.

5. After the plant enters the growing season, the growth factor of the plant is often in the active phase, so it grows faster, and the diseases and insect pests are often more active. Therefore, it is recommended to spray the plant once a week, after several consecutive times, the disease will be removed and the leaves of the plant will gradually return to normal.

In the process of disease control, the main drugs available are Bordeaux solution, topzine, carbendazim, benzoate, Dysen zinc and so on. As long as we spray it with water according to a certain proportion, the effect is very obvious. However, if you want to make the sterilization effect more prominent and achieve the effect of a radical cure, it is recommended that you use the above drugs alternately.
