在代表在桂南、桂西、桂中、桂北的县（市）设点，开展稻瘿蚊药剂防治策略研究。试验研究表明，在秧田、本田同时施药，防治效果最好，其次为秧田不防治本田防治田，较差的是秧田防治本田不防治田。
In this study,3% of'miral'granular medicament was applied to prevent Pachydiplo sis Oryzae in late rice peddy field.The result showed that:The Prevention effect in rice seedling bedand peddy field was obvious.The prevention effect for the former was up to 88.55% and the averageeffect was 78.48% .The Prevention effect for the latter was up to 88.97% and the average effectwas 71.35.Thus the emergence of Pachydiplosis Oryzae was controled effectively.
