Tea plants are prone to banjhi (dormant buds) after autumn, so effective prevention and control are very important
Banjhi in tea plants refers to the phenomenon where tea buds are slow to grow, or bud break is delayed with a low sprouting rate and the new shoots produced are rather small. When tea plants are in the banjhi state, it is extremely favorable for flower bud differentiation, causing the tea plants to produce a large number of tea flowers from late October to mid-November, which consumes a great deal of nutrients, directly affects the growth of tea leaves the following year, and accelerates the aging of the plant. Therefore, preventing banjhi in tea plants is very important. To prevent banjhi in tea plants, the tea garden soil should be fully tilled 3-5cm deep in summer and autumn, so as to cut the soil capillaries and

Identification of Honeysuckle Disease Symptoms and Control Methods
Brown spot disease is a common leaf disease that causes plants to grow weakly. It mostly occurs in the middle and late growth stages, with August and September being the peak period of onset, and it is severe under rainy and humid conditions. In the early stage of onset, small brown spots form on the leaves, then expand into brown round lesions or irregular lesions. Grayish-black mold-like substances grow on the underside of the lesions. When the disease is severe, the leaves fall off, affecting plant growth and flowering. Control method: prune diseased leaves, then spray with 1:1.5:200 Bordeaux mixture, once every 7 to 10 days, for 2 to 3 consecutive times. Powdery mildew occurs under warm and dry

Why are there cone-like objects on young spruce trees? Control of the larch adelgid
On young spruce trees, round objects resembling small cones often appear in June. They are actually galls formed by the damage of the larch adelgid (Adelges laricis).

What are the white hairs on larch leaves". Before the galls split open, remove the galls on spruce by hand. Strengthen preventive measures to prevent the transport and planting of infected seedlings.
