When choosing a tax classification code, you should first judge whether it is a commodity or a service industry, which will help you find it in the category. It is recommended to use search to search for keywords first (do not enter the full name). For example, if a commodity shelf resident list is issued, the reduced range of shelves can be retrieved.
Basic principles of pest control:
The prevention and control of pests and diseases of edible fungi, like the prevention and control of crop pests and diseases, should also implement the plant protection policy of "prevention first, comprehensive prevention and control". Because the environmental conditions required for the growth and development of edible fungi are also very suitable for the occurrence and development of edible fungi pests and diseases, once pests and diseases occur, their development and spread are often very fast and difficult to control.
Especially infectious diseases, whose pathogenic organisms are the same as edible fungi, are also microorganisms, so it is more difficult to prevent and control them. Even if measures can be taken to control pests and diseases in time, it will affect the yield and quality to varying degrees, and it will also consume more working hours and increase the cost. Therefore, taking various measures to prevent the occurrence of pests and diseases before the onset can get twice the result with half the effort.
On the other hand, the prevention and control measures of edible fungi diseases and insect pests have their limitations, and it is difficult to effectively solve the problems of diseases and insect pests by any method alone. It is necessary to supplement and coordinate various measures according to the specific situation in order to get the best prevention and control effect. Therefore, the policy of "prevention first, comprehensive prevention" must be resolutely implemented in the prevention and control of edible fungi diseases and pests.
