How to treat the disease of Yulong grass

Yulong grass is a plant of the genus Artemisia, which grows and divides rapidly, and the planted ground can quickly grow into a dense felt-like turf, which is an excellent ground cover. So how to treat the disease of Yulongcao?

First, how to treat the disease of Yulongcao

1. Anthrax

Balanced spraying of nitrogen, phosphorus and potassium fertilizer, avoid fertilization in hot and dry weather, reduce the number of irrigation, not in the afternoon and night irrigation, in order to reduce environmental humidity. Plant immune or highly resistant varieties of Kentucky bluegrass and spray fungicides if necessary.

two。 Rust disease

When you get sick, you can use diurnal sulfide mixture, Dysen zinc, verapamil, triadimefon wettable powder 1000-2500 times, 12.5% Subali wettable powder 2000 times, and so on.

3. Powdery mildew

Spraying prevention and treatment began at the early stage of the disease in spring, and the effective agents were 25% carbendazim wettable powder 500 times, 70% methyl topiramate wettable powder 1000-1500 times, 50% carbendazim wettable powder 1000 times, and 25% triadimefon wettable powder 2000-3000 times, etc.

4. Cercospora leaf spot

The rational use of fertilizer is beneficial to the control of the disease. Improve the lawn environment and remove trees and shrubs around the grass to keep the grass ventilated and have plenty of sunlight. Disease-resistant varieties have been selected and varieties resistant to Cercospora leaf spot have been bred, such as blunt-leaf grass. The use of fungicides can effectively control the occurrence of leaf spot.

Second, the growth environment of Yulong grass.

Yulongcao is a light-loving and shade-tolerant plant, which can not only grow under strong light but also tolerate a hidden environment. It can also grow normally in the shade with a shading rate of 70% / 90%. However, too weak light can easily lead to excessive growth of leaves and affect tillering.

The optimum growth temperature of Yulong grass is 25-30 ℃, and-3 ℃ ~ 0 ℃ in winter can survive the winter safely. The requirement of soil is not strict, and it grows better in sandy loam with good drainage. Like the moist growth environment, keeping slightly moist during the growth period can make it grow and divide rapidly.

Yulong grass also has a strong ornamental, more resistant to trampling than the general turf, is an excellent ground planting material. It can also be used as slope protection plants, courtyard quilts and flower beds, and can also be used to beautify hillsides and walls, or to be planted in the courtyard to watch.
