Technical Specifications for Integrated Prevention and Control of Yellow Aphids

[Objectives]The purpose was to standardize the scientific prevention and control of yellow aphids and effectively control their occurrence and spread.[Methods]On the basis of consulting domestic and foreign data and standards extensively,a series of related trials were carried out.[Results]Technical specifications for integrated prevention and control of yellow aphids were formulated.[Conclusions]It is of great significance to the healthy and sustainable development of the fruit trees’industry,the implementation of standardized management,the reduction of pesticide uses,and the reduction of damage caused by yellow aphids to fruit trees,and also provides urgent-needed technical support and guarantee for the prevention and control of yellow aphids.

Occurrence Regularity and Integrated Control Technology of Canker in Citrus

Canker is a quarantine bacterial disease that seriously harms leaves,branches and fruits of citrus,leading to a decrease in the production and affecting the commodity and sales of citrus.Citrus canker has the characteristics of fast spreading speed and difficult radical cure.Through the identification of symptoms and a summary of occurrence regularity,the integrated prevention and control technology for citrus canker is described in this article,in order to achieve effective prevention and control and reduce prevention and control cost.

Advances in Integrated Control Techniques of Rice Blast

Rice blast is the most devastating disease in rice,and it seriously threatens the safety of rice production.Improving the ability of integrated prevention and control of rice blast has always been an important part of ensuring food production safety.In the past decade,scientists have made great progress in the prevention and control techniques of rice blast,which paves the way for the green controlling of rice diseases.In this article,the advances in the intelligentization of rice blast field monitoring techniques,the optimization of prediction and forecast modeling system,the research and development of low-toxic and high-efficiency chemical pesticides,biogenic pesticides and inducers and the regulation of multiple ecological factors including variety and cultivation are reviewed,and the new strategies for green controlling of rice blast based on these techniques are summarized.Further,the problems such as high pesticide prices and pesticide residue faced by rice blast prevention and control and the challenge of slow research and development of low-toxic and economical biogenic pesticides are discussed.Finally,the development direction of green controlling of rice blast based on molecular targets,small interfering RNA(siRNA)and CRISPR/Cas9 technologies is predicted,with a view to guaranteeing the safety of rice production.
