Diseases and control methods of Basglobose

Sheath Rust

Usually occurring on the upper and lower sides of leaves and rarely on branches and stems, they appear as raised bracts filled with powdery spores that can be yellow, orange, rusty or even purple-black.

Sheath rust does not cause the death of the plant or the leaves to fall off, but the growth rate of the entire plant will slow down and the growth will become weak.

Prevention and treatment methods

When you find sheath rust on the leaves, cut them off in time.

You can spray with 500-600 times diluted 65% Zineb powder or copper-containing fungicide.

Sclerotium rolfsii

This disease often occurs during the rainy season. In the early stages of the disease, the base of the leaves is covered with white mycelium. In the later stages, when the disease becomes serious, the rhizomes rot and the plants die.

Prevention and treatment methods

Replace the potting soil in time, disinfect the soil with high temperature before repotting, and sprinkle pentachloronitrobenzene powder or lime.

During normal maintenance, pay attention to more ventilation, more light, and keep the drainage system of the potting soil good.

Severely diseased plants should be removed and burned promptly.

anthrax

It can occur at any time of the year, but is more common in hot and rainy seasons.

The spots spread from the leaf tips to the rhizomes. They are brown at first, then gradually expand and increase in number, and many dry black spots appear. In severe cases, the plant dies.

Prevention and treatment methods

During the disease period, you can first spray 800-1500 times of 50% methyl thiophanate wettable powder once every 7-10 days; then supplement it with 1% equal-volume Bordeaux mixture once every half a month, and spray continuously for 3-5 times.

Scale insects

Commonly known as "orchid lice", they reproduce fastest under conditions of high temperature, high humidity and poor air circulation.

It will suck the juice from the leaves of the bracteata, causing the leaves to fall off, the plant to grow slowly, and in severe cases, the plant to die.

Prevention and treatment methods

During the hatching period of scale insects, spray with 1% omethoate or 1500 times 50% malathion.

If there are not many bracts grown at home, you can remove them manually.
