      The overall incidence of pests and diseases tended to trend
      Rice focus on the two migratory insects, stem borers, rice blast. Wheat focuses on scab, stripe rust and aphids. Corn focus on worms, cotton bollworm, corn borer, big blotch. Potato focuses on late blight. Grasshoppers should focus on the concentration of damage in some areas. The above pests and diseases are greatly affected by the climate factors and have the risk of recurrence and epidemic. Farmland weeds tend to occur, with special attention to the problem of weeds in the southern direct broadcast rice fields. Moderately heavy occurrence of rodent pests in farming areas, but special attention should be paid to rodent pests in the structural adjustment area of ​​planting industry.
      The total amount of pesticide demand steady decline
      Pesticide consumption continued to decline. Demand for organic phosphorus will drop significantly, down about 10% over the previous year, carbamate is expected to decrease by about 16% over the previous year. The demand for acaricides increased, the demand for herbicides slightly increased over the previous year, the fungicides were basically the same, and the demand for plant growth regulators rose sharply. Pesticide prices are expected to rise steadily.
      High demand for plant protection machinery warming
      In 2018, there is strong demand for highly efficient plant protection machinery. Plant protection UAVs will continue to heat up with an estimated demand of about 8,000 sorties and an expected operating area of ​​200 million mu. Self-propelled sprayer impacted by aviation plant protection, demand was basically flat, but the demand for orchard self-propelled sprayer increased.
      Pest control will strengthen technical integration
      With the green development as the main line, taking the reduction and control of pesticides as the starting point, the existing agricultural technologies are integrated. Such as pest and disease control, chemical control, biological control and other single technology and soil treatment, fallow rotation, good seed law, biodiversity, protection and utilization of natural enemies and other environmentally friendly to ensure quality and safety of agricultural products organically integrated approach to promote Agricultural green development to provide technical support.
