Control of diseases and insect pests of Polygonatum polygonatum
The main results are as follows: (1) the occurrence of black spot is more common in spring, summer and autumn. Prevention and control methods: clear the garden during harvest, eliminate the disease and disability, and spray 1-1-100-du liquid in the early stage, once every 7 days, 3 times in a row. (2) the grub harms the larvae, harms the roots, bites off the seedlings or eats the roots of the seedlings, resulting in seedling breakage or root cavity, causing serious harm. Control method: the seed can be mixed with 75% octanoic acid EC according to 0.1% seed quantity, or irrigated with 1000 times of 90% trichlorfon solution during the field occurrence period.

The fruiting body is 18. Below C can not differentiate and develop, at 24-28. The differentiation and development between C was rapid, and the mycelium growth temperature was 3-40. C, to 24-30.
