The invention provides a safe and circulating
disease and pest prevention and control method for organic rice and belongs to the technical field of organic
agriculture. The method is characterized in that agricultural prevention and control methods such as rice field-upland field rotation, resistant rice seeds, ploughing and soaking for a long time for killing stem borers and cultivation of strong seedlings are adopted according to
rice growth and
disease and pest occurrence rules, biological prevention and control methods of
stocking of fish fries and tadpoles and biological modelling utilizing a sex attractant are adopted, a physical prevention and control method of mounting of insecticidal lamps and yellow sticky traps is adopted, plants are combined for protecting
copper sulphate products, 100 billion spores per g of
bacillus subtilis,
bordeaux mixture, 40 billion spores per g of
beauveria bassiana WG and 0.3%
sophocarpidine EC, and special and circulating prevention and control on diseases and pests are carried out. The method provided by the invention has the advantages that the problems that prevention and control means on the diseases and pests of the organic rice are less and the effect is poor are effectively solved, the control efficiency on
rice plant hoppers is more than 80%, the control efficiency on rice leaf folders, the stem borers and
weevil larvae is more than 90%, the control efficiency on rice leaf blast is 60%, the control efficiency on neck blast is 80%, the large-scale yield increase is 10%, and safe and efficient internal circulation of prevention and control on the diseases and pests is realized, so that the aim of protecting
ecology is achieved.
