Control efficacy on south rice black-streaked dwarf disease

A trial of control efficacy of different control measures on south rice white-backed plant hopper and black-streaked dwarf disease was conducted in 2013. The results showed that the control efficacy on south rice white-backed plant hopper and black-streaked dwarf disease reached 100.00% when covering fly net in seedling stage. In field period, when treated by soil treatment in seedling field+seeding dressing+applying pesticides (toxic fluoride and nitenpyram) before transplantation and applying pesticides (toxic fluoride and nitenpyram) in field period, the control efficacy peaked with 92.75% on white-backed plant hopper and 80.69% on rice black-streaked dwarf disease, and the rice yield was 526.70 kg per 667 m².
