The brown spot disease began to occur in the cucumber melon period. The middle and lower leaves first developed and gradually developed towards the upper leaves. The diseased leaves began to produce small grayish-brown spots on the leaves, which gradually spread to light brown or brown spots with unequal round or near-circular edges of varying sizes. The lesions are mostly 8 to 15 mm in diameter, 3 to 5 mm in size, and 20 to 25 mm in size. The lesions in the middle of the lesions become lighter, sometimes grayish and grayish brown on the edges. When the humidity is high, sparse gray-brown moulds are sparse on both sides of the lesion. A large number of lesions or several large lesions are merged and the leaves soon die. When the disease is heavy, there will be oval-shaped grayish-brown lesions on stems and petioles. When the lesions spread more, it can cause the whole plant to die.
Cucumber brown spot lighter or emerging symptoms can be used 40% myclobutanil EC 3000 times or 41% EC allicin EC 2000 times spray, once every 5 to 7 days, continuous control 3 times. When the disease is severe, 25% azoxystrobin suspension agent 1500 times or 25% pyraclostrobin EC can be used for spraying. In addition, when the disease occurs at 25 to 28°C and humidity is heavy, prevention and control should also be controlled from the environment, creating ecological conditions that are not conducive to disease.
Handrails play a very important role in the aging of the family. Through a small handrail, create a safe and secure living environment for the elderly at home. When installing the handrail, pay attention to determine the installation height of the handrail according to the height of the elderly at home. The armrest is located at the crotch of the elderly. Generally speaking, it is about 80 to 85 cm from the ground. In order to provide safe and effective support for the elderly, different products need to be selected according to different installation conditions. Some families want to install handrails on non-load-bearing walls. We suggest that they install lining plates first, and then install handrails on the lining plates.
When selecting the material of the handrail, pay attention to the coordination with the furniture environment, create a warm atmosphere, avoid making it cold and hard, and do not give the elderly the illusion of "being a patient". For example, the wooden handrail in the video looks very warm and feels good. It is suitable for the elderly.
