On January 10, the Provincial Plant Protection Station issued the “2011 Prospects for the Main Pests and Diseases of Crops in Our Provinceâ€, said underground pests, wheat red spiders, wheat spikes, wheat weeds, corn borers, corn red spiders, corn-sized spots, and dwarfs. Mosaic disease, potato late blight, soil mites, cotton nursery, cotton blind mites, apple tree rot, apple brown spot, apple spotted deciduous disease, pear small heartworm, protected vegetable downy mildew, open vegetable virus disease, 19 species of pests such as Plutella xylostella will threaten the growth of 175 million mu of crops in our province this year.

It is expected that the basis of this year's pests and diseases will be mainly based on the number of pests before the winter and ecological conditions. The main wheat varieties in our province are generally susceptible to powdery mildew, sheath blight and rust, and have no obvious resistance to wheat spiders and wheat bran. In the past two years, the fresh glutinous corn and the “Xianyu 335†corn variety in our province have been planted in large areas, which provides favorable host conditions for the occurrence of diseases and insects. In addition, most of the main varieties of corn are less resistant to large and small spot diseases. Many potato growing areas are accustomed to self-retaining potato varieties, not paying attention to the selection of resistant varieties, and the resistance of potato varieties is seriously degraded, which is beneficial to late blight and viral diseases. In recent years, the planting area of ​​insect-resistant cotton has accounted for more than 80% of the cotton planting area, which has inhibited the second and third generations of cotton bollworm; the increase of insect resistance has made the cotton blind, whitefly and thrips more serious. Straw returning no-tillage technology and large-scale promotion of mechanized combined harvesting are beneficial to underground pests, pests and diseases.
