two。 Shell worm

Scale insect is a kind of pest that occurs in the growth process of many plants, and brown bamboo is no exception. this pest mainly feeds on the sap in the leaves and stems of brown bamboo, and it gradually absorbs the sap, which leads to the gradual loss of nutrients of brown bamboo and finally shrinks.

The method of controlling diseases and insect pests of brown bamboo: rot bud disease

Brown bamboo rot: mainly harms young buds and tender, at the beginning of the disease, the undeveloped leaves withered first, brown, and then drooped.

The base of the ununfolded leaves in the center turns brown and rotten, giving off a bad smell. The disease also harms palm plants such as loose-tailed sunflower, fish-tail sunflower, coconut, false betel nut and coconut, which is the most serious disease of palm plants. The pathogen overwintered as oospores in susceptible bud leaves and roots, or in soil with diseased remains, and was spread by sputtering with Rain Water or irrigation water and shower water. Rainy season and rainy days, temperature 20 ℃ to 25 ℃, relative humidity above 90%, moisture retention time is easy to develop.

Prevention and treatment: at ordinary times, we should strengthen ventilation and light transmission, and strictly prevent moisture from remaining on the leaf surface for a long time. It was found that a small number of diseased leaves were cut off from the base of the stem and burned in time. If in the early stage of the disease, 50% carbendazim wettable powder plus 75% chlorothalonil wettable powder, or 80% mancozeb wettable powder 500x, or 1 ∶ 1 ∶ 100 Bordeaux solution, take turns spraying heart leaves and the whole plant, once every 10 days, 3 to 4 times in a row, has a very good control effect.

Leaf spot disease of brown bamboo
